The importance of communication protocols Essay

Unless Patton Fuller Community Hospital has an agreement between the two communicating parties information may get lost or un-communicated. This agreement is called the protocol. Communications protocols usually have a number of parts, Handshake, encoding method, compressions methods, packet / frame structure, and addressing.. This is why protocols are often defined by standards bodies, but some protocols SSL can be used widely even though they are not specifically from a standards body. A protocol must be implemented to enable effective, efficient communication by using a set of rules.Protocols are also described as hardware or software components that carry out the OSI model guidelines for transferring information on a network In short – if we don’t have a protocol we won’t be able to communicate between different devices.

Identify the protocols in your design and provide rationale for your decision Define the overall network architecture. The design of a communications system, which includes the backbones, routers, switches, wireless access points, access methods and protocols used May refer only to the access method in a LAN, such as Ethernet or Token Ring Network architecture is the design of a communications network.It is a framework for the specification of a network’s physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are Explain the usefulness of a traffic analysis Its very important to analyze the traffic that comes to your website because it can really make or break your website.But before you can make full use of this traffic analysis, you must understand how to interpret this data. The aim is to use the web traffic statistics to figure out how well or how poorly your site is working for your visitors. One way to determine this is to find out how long on average your visitors spend on your site. If the time spent is relatively brief, it usually indicates an underlying problem.

Then the challenge is to figure out what that problem is. Explain the effect of data rates on each part of the network.Explain the terms latency, response time and jitter and describe their effect on overall network performance and on the performance of your chosen organizations network. In web performance circles, “latency” is the amount of time it takes for the host server to receive and process a request for a page object. The amount of latency depends largely on how far away the user is from the server. For obvious reasons, tackling latency is a top priority for the performance industry.

There are several ways to do this: * Allow more requests to happen concurrently. Shorten the server round trips by bringing content closer to users. * Reduce the number of round trips. * Improve the browser cache, so that it can (1) store files and serve them where relevant on subsequent pages in a visit and (2) store and serve files for repeat visits. Jitter is the amount of variation in latency/response time, in milliseconds.

Reliable connections consistently report back the same latency over and over again. Lots of variation (or ‘jitter’) is an indication of problems. Jitter shows up as different symptoms, depending on the application you’re using.Web browsing is fairly resistant to jitter, but any kind of streaming media (voice, video, music) is quite susceptible to Jitter. Jitter is a symptom of other problems. It’s an indicator that there might be something else wrong.

Often, this ‘something else’ is bandwidth saturation (sometimes called congestion) – or not enough bandwidth to handle the traffic load. Describe strategies to ensure the availability of network access in switched and routed networks.http://wiki. answers. com/Q/Why_is_a_communication_protocol_important#ixzz2E2rz1Ct5
