IEEE 802.16 supports four service classes. Which service class is the best choice for sending uncompressed video?
Answer to relevant QuestionsGive two reasons why networks might use an error-correcting code instead of error detection and retransmission.Consider the interconnected LANs shown in Fig. 4-44. Assume that hosts a and b are on LAN 1, c is on LAN 2, and d is on LAN 8. Initially, hash tables in all bridges are empty and the spanning tree shown in Fig 4-44(b) is ...To make VLANs work, configuration tables are needed in the switches and bridges. What if the VLANs of Fig. 4-49(a) use hubs rather than multi drop cables? Do the hubs need configuration tables, too? Why or why not?Consider the network of Fig. 5-7, but ignore the weights on the lines. Suppose that it uses flooding as the routing algorithm. If a packet sent by A to D has a maximum hop count of 3, list all the routes it will take. Also ...Compute a multicast spanning tree for router C in the following subnet for a group with members at routers A, B, C, D, E, F, I, and K.
