business that will need to consider WAN technology using Frame relay technology within the company for the future expansion to other towns and cities. The Frame relay analysis will include the operation of frame relay, what equipment is needed, what switching technologies are employed by frame relay and how frame relay is actually brought into the business premises. Frame Relay in a WAN Frame Relay Frame Relay is one of the most common WAN protocols. This high performance protocol operates at

is available for use by those two devices only. In contrast, packet switched services enable multiple connections to exist simultaneously between computers over the same physical circuit or even over different physical circuits. Also with packet switching different locations can have different connection speeds into the common carrier cloud. Circuit-switched services typically use a pay-per-use model, while dedicated circuits are billed at a flat fee per month, and the user has unlimited use of the

Part-1 1. What are common carriers, local exchange carriers, and interexchange carriers? A common carrier is a private company that sells or leases communication services and facilities to the public. Common carriers are profit-oriented, and their primary products are services for voice and data transmissions, both over traditional wired circuits as well as cellular services. Common carriers often supply a broad range of computer-based services, such as the manufacturing and marketing

of decency – cleverly enough – the “decent” behavior which represents the upper tiers of the value orientation scale (Anderson 2000: 35). On the other hand, many people struggle financially and thus have to “hustle” and perform an act of “code-switching” between decent and “ghetto” (or “street”) behaviors in order to secure their lives yet still fit into the ideals of society (Anderson 2000: 35-37). These acts (or lack thereof) create a marker for various individuals as to how high or low on this

Individual Assignment: Protocol Paper NTC/362 Individual Assignment: Protocol Paper Describe Open Systems Interconnection (OSI) protocol model. The Open Systems Interconnection (OSI) model is a seven-layer logical network architecture that is used to define the network protocol standards to enable OSI device to communicate to another by exchanging information. (Goleniewski, 2007) The seven layers in the OSI model include the physical layer, data link layer, network layer, transport layer,

Protocol Paper NTC/362 Fundamentals of Networking Protocol Paper Introduction Switching, whether it is packet or circuit, is an essential portion of any network. By not using the right equipment, or using it properly, you can cause massive lag time or jitter within your own system. This will result in packet collision, loss of data, and could result in loss of business. Open Systems Interconnection Protocol Model In order for two computers to be able to interchange data and information

question number 3 I do not have significant answer for it so I just going to try my best to answer it usually the technical problem with this issues is could be packet switching delay. Because the latency accrued when switches and routers forward data. The latency depends on the speed of internal circuitry and CPU, and the switching architecture of the internetworking device. or the problems could accrued from serialization delay. The time to put digital data onto a transmission line, which depends
