IP and OSI Networking Essays

TCP/IP and OSI Networking Essays TCP/IP and OSI Networking Essay TCP/IP and OSI Networking Essay In this essay I intend to analyse why networking software is divided into layers, and to evaluate the advantages and disadvantages of such a division. I will then go on to analyse what the main differences between the networking protocols known as OSI and TCP/IP are. I will also attempt to analyse what factors led to their successes and failures respectively in terms of their diffusion into the technology sector. However, before we can discuss this, we must first be sure that we are aware of the meanings of terms such as networks, network architecture, protocols, and distributed networks/systems so I will begin by defining these phrases. Essentially, a network is the connection of two or more computers for the purpose of data communication and resource sharing. the formal definition of a network could be given as a number of interconnected devices capable of communicating and sharing each others resources (Bandyo-padhyway, 2000:157) As can be seen from the above quote, networking offers organisations a wealth of benefits. A network enables an organization to centralize its computer system and allows users to access the facilities of a large computer system via desktop computers. (Bandyo-padhyway, 2000:157) It could be said that network architecture is, in theory, a model for the set-up of a network. To help deal with this complexity, network designers have developed general blueprints usually called a network architecture that guide the design and implementation of networks. (Peterson Davie, 1996:29) Protocols, in the networking sense, could be considered as sets of rules or procedures that control how a message is sent from sender to receiver and all the factors involved in this process. A protocol is a set of rules or conventions which govern the way a message is transmitted from the sender to the receiver passing through a number of steps and via a number of network elements. (Bandyo-padhyway, 2000:178) Finally, a distributed network/system is where the tasks to be to be performed are distributed among a number of small PCs that are coordinated by a larger central computer. (Bandyo-padhyway, 2000:173) Having defined the aforementioned basic technological terms, I can now go on to my analysis of the reasons why networking software is divided into layers. The primary reason is that having separate distinctive layers reduces design complexity. By this, I mean having different layers means certain operations and tasks that must be carried out, can be carried out in a simple and organised order, rather than all at the same time. First, it decomposes the problem of building a network into more manageable components. (Peterson Davie, 1996:30) Layering allows for changes to be made at a specific layer, as a result of new ideas/innovation, and will not disrupt the software at other levels. Second, it provides a more modular design. If you decide that you want to add some new service, you may only need to modify the functionality at one layer, re-using the functions provided at all the other layers. (Peterson Davie, 1996:30) This means that it accommodates incremental changes more readily. (www. cs. wpi. edu/~rek/Undergrad_Nets/B03/HTTP_DNS. pdf) Another advantage of layering is that details of how the lower level services are implemented are shielded from the higher levels, allowing the higher levels to function more efficiently. This can be seen, from a more technological point of view, in the following quote. Many times there are multiple abstractions provided at any given level of the system, each providing a different service to the higher layers but building on the same low-level abstractions. (Peterson Davie, 1996:30) A final advantage of layering is that as a result of the different types of layers, making it so different types of translations can take place; different types of hardware are enabled to communicate. Having looked at the advantages of layering, I will now spend some time discussing its disadvantages. Some functions (like FDDI station management) really need to access and operate at multiple layers. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) As the above quote displays, one disadvantage is since the software is split up into layers, functions will operate at one level at a time, where as some functions have the necessity to operate at several layers. Poorly conceived layers can lead to awkward and complex interfaces. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) This quote shows us that unless a large amount of thought and work goes into each individual layer, then a very bad and hard-to-use interface can be the end-result. Another disadvantage is if new design for a layer is done, an old layer may become inappropriate or unsuitable given the properties of the new layer. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) A final disadvantage of layering is something known as information hiding, this may take place and this can lead to inefficient implementations. (www-inst. eecs. berkeley. edu/~cs268/ sp03/notes/Lecture2. pdf) I have discussed why networking software is divided into layers as well as evaluating both the advantages and disadvantages of layering. I now intend to introduce the first of the aforementioned protocols Open Systems Interconnection (OSI), before then introducing the second. A number of different types of distributed systems were being developed in the 1970s and as a result, a range of standards had to be introduced. (Halsall, 1996:11) An organisation called the International Standards Organizaton (ISO) created the ISO Reference Model for OSI. The ISO was a body founded in 1945 to coordinate international standards for a wide range of industries. (The Internet in the Arena of International Standards) Below is a diagram of the OSI protocol, taken from Peterson and Davie. As can be seen, the OSI protocol has seven layers. The application layer provides the user interface to a range of networkwide distributed information services. The presentation layer is associated with the representation of data during transfer between two communicating application processes. The session layers job is to set up a communication channel between two communicating application layer protocol entities during a network transaction. The network layer is responsible for establishing a networkwide connection between two transport layer protocol entities. The link layers job is to build on the physical connection provided by the network to provide the network layer with a reliable information transfer facility. Finally, the physical layer is associated with the physical and electrical interfaces between the user equipment and the network terminating equipment. (Halsall, 1996:16, 17, 18) I will now introduce the second networking protocol so that we have a good understanding of them both, before analysing their differences. The second protocol is called Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP was developed by the US Department of Defence (DOD) research project to connect a number of different networks designed by different vendors into a network of networks. (www. yale. edu/pclt/COMM/TCPIP. HTM) The idea behind the DODs thinking was that in the Cold War, if the right designated place was bombed successfully, then the whole countries network communication facilities would become inoperable. This was obviously be a bad thing and so the DOD wanted to develop a standard that would connect all the networks together to prevent this from happening. Below is the model of the TCP/IP protocol, taken from (www-staff. t. uts. edu. au/~sean/DSP. dir/dsp00s. dir/lect1. dir/sld014. htm) As can be seen, the TCP/IP protocol has only four layers. The application layer handles high level protocols. The transport layer deals with quality-of-service issues. The internet layer determines the path to forward packets of data. The network layer is concerned with all of the issues that an IP packet requires to make a physical link. (www-staff. it. uts. edu. au/~sean/DSP. dir/dsp00s. dir/lect1. dir/sld014. htm) Now that I have briefly introduced both of the protocols, I will now move on to my analysis of their main differences. A difference between the two protocols in terms of their establishers is that OSI was orally established by Telcos, a telecommunications company and had a large connected emphasis linked to it. TCP/IP came more from a computing background with a large connectionless emphasis associated with it. Another difference that should be noted is that the two models have opposing approaches. The OSI model has a top-down approach meaning the processes that take place within the layers start at the top of the model and work their way down to the bottom. The TCP/IP model has a bottom-up approach meaning the processes taking place within the layers begin at the bottom of the model and move upwards. As can be seen from the models, the visible difference is the number of layers present within each. The OSI protocol has application, presentation, session, transport, network, data link, and physical layers. Where as the TCP/IP protocol has only application, transport, internet and network layers. Even though some of the layers have different names, they essentially do the same thing. However, the presentation and session layers that are in the OSI model are not present in the TCP/IP model. This makes the two protocols technologically different. First there were the technical differences, chief among them that OSI had a more complicated and compartmentalised design. (Lyon Hafner, 2003:246) The above quote points out how the OSI design was considered to be very large and complex where as the TCP/IP design was far more simplistic and smaller. On the OSI side stood an entrenched bureaucracy, with a strong we-know best attitude, patronizing and occasionally contemptuous. There was a certain attitude among certain parts of the OSI community whose message was, Time to toll up your toy academic network,' recalled one ardent TCP/IP devotee (Lyon Hafner, 2003:247) We can see from the above quote that OSI was regarded as a potential official standard with a considerable amount of bureaucratic support, as opposed to TCP/IP, which was seen by some as a toy network for the academic world only, and would never have any real chance of becoming an official standard networking protocol. The reason being was that the OSI was created by the ISO, and the ISO had long been responsible for creating international standards for a variety of industries, as the following quote displays. Since the 1940s, ISO had specified worldwide standards for things ranging from wine-tasting glasses to credit cards to photographic film to computers. (Lyon Hafner, 2003:246) As a result of this official standardization reputation that ISO had created for themselves, OSI was backed by several governments, led by Europe, and was thought to be meeting the needs of the whole world. Another difference between TCP/IP and OSI, was that TCP/IP had actually been implemented where as the only thing OSI had to offer was the design model for the protocol, as the following quote shows. And it was a design, never tried. As far as the Internet crowd was concerned, they had actually implemented TCP/IP several times over, whereas the OSI model had never been put to the test of daily use, and trial and error. (Lyon Hafner, 2003:247) An extremely large difference between the two protocols is in relation to their impacts on the networking world respectively. OSI failed to become to the official international networking standard that it was predicted to be. TCP/IP, contrary to what many had anticipated, was a huge success within the networking protocol world and is used across the world today. However, one must ask, what factors led to this outcome? One factor was that one key TCP/IP developer, Bill Joy, decided that TCP/IP when bought was to come with free networking software, which was based on Unix. As can be imagined, the fact that one received free Unix networking software when buying TCP/IP with no extra charge dramatically helped push TCP/IP further than OSI. The first Sun machines were shipped with the Berkeley version of Unix, complete with TCP/IP. Berkeley Unix with TCP/IP would be crucial to the growth of the Internet. When Sun included network software as part of every machine it sold and didnt charge separately for it, networking exploded. (Lyon Hafner, 2003:250) To clarify, Sun was the name of the computer company that Joy joined as the Unix expert. Another factor that led to TCP/IPs success was the fact that ARPANET decided to switch over to it on January 1, 1983. ARPANET was the resulting internetwork developed when computer networks associated with a large number of universities and other research establishments were linked and it was in large usage. (Halsall, 1996:19) As a result, TCP/IP was pushed even further ahead when ARPANET switched its protocols from Network Control Protocol to TCP/IP as this meant only machines running the new protocols could communicate over the network. Lyon Hafner, 2003:248) Dennis Jennings tells us of a factor that largely contributed to the failure of OSI when it was announced by the manager of a company called ICL at a review meeting that the output of the OSI research would not be in the interests of ICL. The Commission then told ICL that they could do what ever they like. This meant that where would be no available implementation opportunities for OSI once the research had been completed, and Jennings feels that this made it so that OSI had absolutely no chance of success. So what ever the merits of having a set of open OSI protocols, it was a serious attempt to provide an available solution, and the Commission allowed the project to throw it away. OSI died at that meeting. Without available implementations, it had no hope. (Randall, 1997:218) Another thing worth saying is that because the Internet boomed and became increasingly popular, and TCP/IPs design had a layer devoted to the Internet, TCP/IPs popularity was again increased further as a result of the Internets rapid growth. One could argue that OSI, being a protocol that did not include a layer for the Internet in its design, was over-run by the Internets growth. A final factor I would like to mention is the belief that a main reason OSI was not a success was because it got too preoccupied with the standards process and attempting to approve too many that it became caught up with them. It is seen by some that this caused it to fail as it distracted OSI from the one single standard that it was supposed to produce, the following quote shows this. But ISOs plan to make the OSI protocols a single standard for all computer users was defeated by ISOs own practice of approving multiple standards. (International Standards). To conclude, the concept of layering within networking software is in usage as it provides many advantages in terms of the softwares performance itself. Although, it does also pose some disadvantages, I feel they are small in number are not strong enough to outweigh the advantages. My analysis of the two networking protocols, OSI and TCP/IP, shows their main differences in terms of technical as well as social factors. I have also discussed the two differing impacts the protocols had in the world of networking and have attempted to explain why by looking at important factors associated with their diffusions. From my analysis, one can see that OSI was mostly a failure, as opposed to TCP/IP which won the protocols war and is in large international usage today.

7 Reasons Why Slowing Down At Work Is a Good Idea

7 Reasons Why Slowing Down At Work Is a Good Idea You might think the best and most productive worker in the room is the one balancing 17 tasks at once and zooming up and down the halls, but you’d be wrong! It turns out that sometimes the smartest and most successful people are the ones who ease up on the throttle, turn down the pace, and work more slowly and mindfully. Here are just a few ways how a  slower approach to work can pay off hugely in the long run.1. You need more time than you think†¦ to think.It’s hard to do your best cognitive and creative work in the frenzy of the workplace. What if that frenzy were just†¦ pointless, though? If you start to think â€Å"slow,† you’ll give yourself time to ease the pressure, get creative, let your ideas simmer until they’re ready to emerge. Instead of jumping rapidly- and inefficiently- from task to task, try deliberately slowing down. You might be amazed at how much time you actually have in a given day when working effectively instead of in a frenzy.2. Your rational brain kicks in.You’ll be more confident in your ideas and decisions when you make them mindfully. Move away from your super fast automatic or â€Å"sympathetic† nervous system and those knee-jerk reactions, and towards the slower, more logical â€Å"parasympathetic† nervous system. You’ll get out of mental loops and autopilot and come to more logical decisions about which you can be more confident.3. Your listening skills improve.Are you frantically tuning people out, smiling and nodding because you’re just too busy to put down your task and listen? Curb this common behavior and learn to truly process the ideas and concerns of others. You never know when this might help you find the missing piece to a personal puzzle, or gain more respect and traction among your coworkers.4. You’ll make fewer mistakes.Working this way, slowing your pace to be more meticulous and measured, means that you’ll make fewer mist akes. And the mistakes you do make will be much easier to rectify. You might even learn something and have the time and space to internalize that lesson before moving on.5. Your brain will remember how to act.This kind of practice is also great because it will eventually train your brain to slow down and work this way automatically. Soon it won’t be a project, but just the way you work.6.  You can eliminate unnecessary work.Sometimes busy work is just that†¦ busy. Working slowly can help you realize which tasks are not necessary. Save yourself and your coworkers from extraneous work. Don’t create extra tasks for yourself or others when you could concentrate on the projects that really matter.7. You’ll learn to let go of stress.Instead of chewing your nails down to the quick and tapping your feet annoyingly while waiting for coworkers to finish off their tasks, concentrate on the work on your desk. Do it right, rather than fast. And instead of concentratin g on getting everything done, try working just on the task at hand and getting it done right. Relax a little and understand that it’s just not possible to leave work every day with a blank to-do list.

Accounting Theory (Australia) Essay Example | Topics and Well Written Essays - 500 words

Accounting Theory (Australia) - Essay Example Presently, the Japanese Generally Accepted Accounting Principles are recognized by the European Union. The Financial Services Agency of Japan is also working to have common regulations with the International Financial Reporting Standards. The Business Accounting Council has come up with deliberations about the treatment of consolidated financial statement based upon International Financial Reporting Standards within the purview of Japanese Security Exchange Law. This measure has been presumed as the regulatory response of Japan as it involves the treatment of IFRS based consolidated financial statement prepared by issuers of both, Japan as well as foreigners, to be listed in the Japanese market. Japan and other Asian countries should participate more into the regulatory authorities for their own benefit. Their valuable presence in the committees would voice their needs and requirements. Presently, the Accounting Standard Board of Japan is trying to build up consensus over various financial regulatory issues among the Asian economies. Among the various regulatory issues, BASEL reforms have been very crucial for the transformation of the banking sector. It has been observed that there have been certain issues in terms of compliance of BASEL norms in Japan. The financial disorder prevalent in the last decade and the continuous postponement of resolution of non – performing loan (NPL) hindered compliance with the BASEL standards in Japan along with propagating political intervention in the economy of Japan that considerably hampered bank regulations. Today, it is almost certain in the periphery of the financial regulations that IFRS would make way for GAAP in due course of time as it has already adopted by European Union. Japan should focus more on accounting standards of IFRS rather than that of GAAP to be in line with the

Select a Code of Conduct to Revise Assignment Example | Topics and Well Written Essays - 500 words

Select a Code of Conduct to Revise - Assignment Example In addition, the communication language in which the code of business conduct should convey the message should be understood by the employees (Waldmann, 2006). Corporate companies like Diageo and Coca-Cola prohibit their employees from taking for themselves or directing business opportunity to other people that business opportunity that the organization has turned down. This code of business conduct needs to be revised. This is because of the fact that if organizations like Coca -Cola are not interested with the business opportunity they should therefore provide the employees with the chance of taking up the challenge and provide the services needed. This should be allowed to provide the employees the chance to grow themselves. If an organization is not interested in a business opportunity, then it means that it is giving other people that opportunity. Therefore, why not give the same opportunity to the employees to empower them and make them have better income and advance their careers (Barth, 2003). However, this opportunity should not be discovered using corporate property or information. Diageo should ensure that employees should not use the organization’s resources, information or position for personal gain or competing with the firm. It may be hard to sometimes determine the line between personal and firm benefits. The best action to do is ask for permission for the use of any firm property or services that is not solely for the benefit of the organization. In addition, in order to protect the interests of an organization, it is important for companies to monitor and review all data and information contained on an employee’s company issued property. This is for the sole purpose of protecting the organization’s information from outsiders. Moreover, strict measures and discipline should be instilled to those violating the rules. In conclusion, it is important for organizations to have the code of business conduct as it serves as a

Development of Social and Emotional Identity

The interview was conducted with an adolescent 18 year-old sophomore at a Alternative Education Program named Phil (fictitious name for confidentiality). Phil was a senior athlete, majored in English and was on the honor roll. The interviewer asked the question, â€Å"How would you describe yourself,† Phil sat up straight and stated that he had some problems during his elementary, middle and high school because of his choice of peers some who smoked marijuana. Phil denies any psychiatric illness during this time. Phil relates that at the age of three, he struggled with his parents and siblings over autonomy issues, although his parents were very involved in his academic goals. The first years of school are an important if not critical arena time for social, identity and conflict-management skills. Gibbs, J.T., (1987) Phil stated as hockey practice began, he had a falling out with his teammates due to a girl he was dating which was a peer’s ex-girlfriend. Phil relates that he realized social acceptance from his peers to be very important at this time. Phil stated ‘feeling intense negative feelings from his teammates had leaded him to withdrawal†. Phil states that being an unpopular student made him react in ways that are inappropriate to the situation; he tried to join others by calling attention to himself, talking about other students, inserting his own opinions and feelings and asking informational questions just to fit in with people. In Phil’s sophomore year, he realized that he had to make accurate judgments about the social competence of his peers. When asked the question â€Å"How important is popularity at school?† Phil stated that popularity is a measure of a student’s social standing with peers. Studies that include observation of elementary, middle and high school student in the classroom and in the playground show that popular students have specific positive qualities that appeal to peers (and to their teachers, too) Gibbs, J.T., (1987). Phil also stated, â€Å"The students are people who value other people and know their own value to other people. Students are sought out as friends, and actively seek others out for friendship† (Phil, 2010) Phil, he states that social status can change at the drop of a baseball cap, such as the popular students are well liked by many children ( and adults), disliked by few, and they have emotionally close, long-lasting one-to-one friendships with peers. These students make friends easily and well, and they keep them. Their friendships are intimate and satisfying. Phil mentioned that he realized what he had been through and the sad truth is, once a student in elementary, middle and high school is rejected, because of their social status seems to be more a matter of default than the product of a specific behavior style. He goes on to say, â€Å"if one thing has become clear it is that social emotional and identity status becomes a self-fulfilling prophecy.† (Phil, 2010) For most teenagers, adolescence is a time of fast growth physically, mentally, emotionally and socially. This period is mark by developing a sense of identity, self-esteem, and relationships with peers (Reference here). Although teens may experience new encounters and abilities during this period, it also can be painful as they try to make sense of the world and their place in it. Phil went on to say that in some students, the hyperawareness of social performance can bring on social anxiety and insecurity and shyness symptoms, as well a new image of themselves as shy and eager around others. In addition to Phil’s statement, he replied that the emphasis on emotional control of middle and high school students’ gives way to mature social problem solving in which emotion and social reasoning become integrated. Increasing maturity also brings the ability to make finer distinctions in the social behavior and acceptability of their peers (Phil, 2010). As the interview culminates, Phil mentions that even if victimized elementary, middle and high school students change the way they are with peers, they will not become popular overnight. It takes time to change negative reputation among peers. Phil states that increasing the social opportunities of all students, and those who have been victimized would help individual outcomes. Troubled children and students need to experience positive social interactions that can benefit many aspects of their lives (Phil, 2010).
