1. Consider a network including two clients and three network routers. In this example, client C1 is connected to router R1, R1 is connected to router R2, R2 is connected to router R3, and R3 is connected to client C2. Suppose in this example C1 and C2 have 10 simultaneous UDP connections for data transfer. Explain how each of the scenarios listed below influences the data transferred between the clients. (a) All routers have infinite buffer space, 10Mbps links between clients and routers (b) All routers have finite buffer space, 1Gbps links between clients and routers. (c) All routers have finite buffer space, 10Mbps link between (C1, R1) and (R3, C2), 1Gbps link between (R1, R2) and (R2, R3) 2. Consider three popular wireless/NAT routers: Linksys WRT54GL, D-Link DIR-655, and NETGEAR WNDR3700-100NAS. Compare these devices for performance, endurance, and security. List technical com- ponents of each device such as CPU, Memory, WAN/LAN interface type, Wi-Fi specifications, etc 3. Consider a subnet with prefix 192.168.1.1/24. Suppose the administrator of that network wants to create eight subnets from this block, with each block having the same number of IP addresses. What are the prefixes (of form a bo.c.d/x) for the eight subnets? How many unique devices can each subnet support? 4. In this problem, you will research the impact of NAT routers on creating TCP/UDP sockets. Suppose you have a video of questionable taste that you would like to share with a friend. Both you and your friend are connected to different NAT routers. Devise a solution that will allow you to create a socket to your friend's computer from your own computer to complete the file transfer 5. P26 from the textbook. Once you have the spanning tree generate the forwarding tables for all routers in the network 1. Consider a network including two clients and three network routers.
