Consider a datagram network using 8-bit host addresses and suppose that a router uses longest-prefix matching with the following forwarding table: Prefix Match Interface 01 1 11 2 011 3 110 4 001 5 otherwise A datagram with destination address 11110111 will be forwarded to interface number A datagram with destination address 01000001 will be forwarded to interface number A datagram with destination address 00101101 will be forwarded to interface number 4 || 2 || 1 || 6 || 5 Consider the following figure for which there is institutional network connected to the Internet. Suppose that the amount of time it takes from when the router on the Internet side of the link forwards an HTTP request until it receives a response is 2.3 seconds on overage. If a web cache is installed in the institutional LAN with a hit rate of %46, what is the average end-to-end delay between the browsers in the institutional network and the servers? Hint: You can ignore the access link delay and the LAN delay. WE origin servers public Internet 1.54 Mbps access link institutional network Gbps LAN local web cache Answer: Consider the following hierarchical OSPF network with 3 local areas (Area 1, Area 2, Area 3) and a backbone (Area 0). Router R2 connects to another AS (Autonomous System) thus Rl belongs to another AS. Based on these information determine the type of the following routers. BGP Area 0 RO R4 R5 RIZ RII R10 Area 1 Area 2 /R13 Area 3 R14 Rilis a/an R13 is a/an R2 is a/an The last IP address that can be assigned to a host in subnet 192.168.5.0/28 is as follows: 192.168
