Preview: ... lity of service as frame relay uses variable length packet it’s always difficult to ensure quality of service compared to fixed length packets. <br><br>To overcome potential congestion, it should be ensured that the provider’s Committed Information Rate (CIR) is sufficient to meet the needs of their network’s requirement. CIR is minimum level that the provider guarantees to deliver at least this amount of data transmission even during heavy network load. <br><br>Before making any final decision we should first take a look at the alternative WAN protocol.<br><br>X.25 is older technology similar to Frame Relay but its not as efficient as Frame relay is. X.25 was designed when most telecommunications lines were analog and therefore X.25 loses a big percentage of throughputs to error checking overhead compared to Frame Relay. X.25 have no advantages over Frame relay and should not be used unless there are no other alternatives available.<br><br>ATM: Difference between ATM and Frame Relay is that ATM uses fixed-length packet whereas Frame Relay uses variable-length packets. ATM assures quality of service as it uses fixed-length packets compared to Frame Relay. ATM is a very good option to choose only if the office can afford higher price.<br><br>After considering all the WAN protocols, its recommended to use Frame Relay for the offices in consideration for designing a WAN. As we have examined all other alternatives and decided that Frame Relay offers the best combination of performance and price for our offices’ WAN needs and so the next step should be to design the network to efficiently connect the office sites.<br><br><br><br>Topology:<br><br>We would be connecting two offices, and in future there could be a requirement to add more offices and thus here, we choose mesh topology to provide some redundancy in communication links. This arrangement can be either full mesh where each site has a connection to every other site on the network or a partial mesh where sites have connection to one or two other sites but not all the sites on network. It seems an easy option to choose a full-mesh as a better option to connect as it’s most re ...
