Frame Relay and Leased Lines Essay

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

Communication has been a real asset to humankind by having the capacity to exchange data starting with one then onto the next. While numerous diverse structures exist, for example, gesture-based communication, talking, and non-verbal communication, it is telecom that has changed the world all through the last hundred or more years. The information transfers framework has three separate things with a particular end goal to transmit what will exhibited. Person begin by the source or transmitter, which is then put into a medium or correspondence line, and ultimately there is a sink, or beneficiary that the data is yielded

24. Pg 6 Phase 2 Infrastructure. Bell/AT&T were the first. Microprocessors and packet switching also were part of the new way.

The organization will reap in high sales and production and possible lower costs in employee wages from less workload. The network system will work at a faster pace and if using the voice-over IP system, communication and management costs can be reduced.

Framing: Data link layer receives the data from the network layer & divide it into manageable units called frames.

Frame Relay does have some draw backs such as error checking packets. This can be a huge deal if there is a lot of traffic on the network because it will not detect corrupt packets. Which means individual packets could be lost when transmitted. Frame Relay relies on the end station to send the SYN/ACK back. If a SYN/ACK does not come back then the Frame Relay protocol will just drop the frame. From each individual router a T1 line will be used to help reach the desired bandwidth from server to a switch. From this point you will have to use leased lines which will affect the budget of the project. With the implemented plan, the goal was to keep the desired bandwidth and allow room for growth.

Your question: Explain what packets and frames are? Describe the different characteristics between each other.

Packet switching: This network technique groups all types of the data in sized blocks that get transmitted via a medium shared by multiple communications sessions providing more efficiency to application in the network.

VLANs or Virtual Local Area Networks are logical local area networks that extend beyond the traditional LAN architecture. Because a VLAN is a logical entity, creating and configuring a VLAN is done completely in software. The advantages to using this type of LAN include but are not limited to the ability to conserve the network resources, to bridge geographical drawbacks, and to better manage the movement of personnel and equipment. To understand the need for VLANs you must first understand the Local Area Network (LAN). The definition of a LAN started as a group of computers that were connected in the same area, but today’s LAN is defined as a single broadcast domain. This is explained easily by looking at a large organization where each department would be on a separate LAN found behind a router or switch. With today’s expanding networks it has become important for these

I have described my observations of the rate of change in Ethernet data transfer capacity.

are setup, then data (packets) transmissions will be as fast and easy as in the tradition wired

It wasn’t until three year later, in 1965, that a working method was created. This method was called “packet switching,” and would allow information to be transferred between computers on the government’s

ATM is a connection-oriented, unreliable, virtual circuit packet switching technology. Unlike most connectionless networking protocols, ATM is a deterministic networking system. It provides predictable, guaranteed quality of service. From end to end, every component in an ATM network provides a high level of control. ATM technology has:-
