YOU DECIDE LLOYD BARTSHE NETW 208 Scenario Summary Over the past several weeks, you have carefully considered the devices and media that will be used to communicate between the Pittsburgh and Cleveland offices. You must now move your attention to moving data between the two networks. Kim has recently bought a networking book and began reading up on Frame Relay, but was confused by all of the new terminology. Perhaps with your networking knowledge, you can help Kim in this area. First I think

Mohamad Alshaar Assignment 4 What are common carriers, local exchange carriers. And interexchange carriers? Common carriers are private companies like AT&T and sprint that provide communication services to the public. LEC are common carriers that provide local telephone services, and IXC are common carriers that provide long distance services Who regulates common carriers and how is it done? In the US the FCC (Federal Communications Commissions) is an agency that regulates voce and data communications

There was an increased need for higher speeds, an increased need for larger bandwidth efficiency, an increase in intelligent network devices that lower protocol processing, and the need to connect LANs and WANs. The Frame relay evolved passed the X.25 as a less careful, but less burdensome protocol designed to transmit packets across a network. (Horton, 2010) Frame relay is known all around the world in many different networks. There are many terms that describe and refer to Frame relay and

user has unlimited use of the circuit. All three services are leased from a provider and run through the service providers cloud. 19. How does a reliable packet service differ from an unreliable packet service? A reliable packet service, like X.25, guarantees error detection and delivery of the packets because control is done at each node in the network. An unreliable packet service, like ATM, does not perform control, which is left up to the software at the source and destination. 29. Describe

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

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.
