Suppose a small ISP X pays a larger ISP A to connect him to the rest of the Internet and also pays another ISP B to provide a fall-back connection to the Internet in the event that he loses connectivity via ISP A. If ISP X learns of a path to some prefix via ISP A, should he advertise that path to ISP B? Why or why not?

Consider the network shown below, and Dijkstra's link-state algorithm. Suppose that Dijkstra's algorithm has been run to compute the least cost paths from node E to all other nodes. Now suppose that source node E has a packet to send to destination node A. What is the first router to which E will forward this packet on its path to A? F A 3 2 B C 4 D 10 4 E 4 2

Consider the following situation: Source node has packets number 1, 2, 3, 4, 5, 6, 7, and 8 to send to the destination Source starts transmitting and packet 3 is lost on its way to its destination. The rest of ACK and data packets arrive successfully Window size is 5 packets ACKs are packet number-based. Draw a diagram that illustrates what happens in the network during sender’s transmission of packets 1 – 8 when Go-Back-N protocol is used and a diagram that illustrates what happens when Selective Repeat is used. Initial diagrams have been already drawn for you. You need to complete the drawing.
Consider 2 small ISPs Y and Z and two large ISPs A and B. Y pays A (but not B) to connect it to the rest of the Internet, while Z pays B (but not A) for its connectivity If ISP A learns of a path to some prefix via ISP B and ISP Z, should it advertise that path to ISP Y? Why or why not?

Consider a slightly different AS-level topology running BGP routing below. Suppose x starts by announcing a path “x" for destination x to A. Upon receiving the path announcement, A learns a new path to reach x - “A". A updates its routing table and announces the new path "Ax" for destination x to B and C. Upon receiving the announcement, B learns a new path to reach x - "BAx" and updates its routing table. B y What will C learn as a new path to x upon receiving the announcement from A? Suppose B announces the new path for destination x to C. What will C learn as a newpath to x upon receiving the announcement from B? Continue from (b). If z is C's customer and forwarding packets for z with shorter delay will satisfy z better, which path for destination x would C prefer to announce to z? And why? Continue from (b). z is C's customer and C cares less of the customer's satisfaction. If B charges less per unit traffic to forward for C and A charges more, which path would C prefer to…
Suppose A is connected to B via an intermediate router R, as in the previous problem. The A-R link is instantaneous, but the R–B link transmits only one packet each second, one at a time (so two packets take 2 seconds). Assume A sends to B using the sliding window protocol with SWS = 4. For Time = 0, 1, 2, 3, 4, state what packets arrive at and are sent from A and B. How large does the queue at R grow?
What information in the IP header should be supplied to ensure that a packet is sent? Is it limited to N routers?
Each active interface of Distance vector gets frequent transmissions of the whole routing table that Distance vector maintains. The link status protocol broadcasts information about the state of a router's own connections to all other routers in the network. Each statement has two ideal examples that show how the Link state and the Distance vector may be utilized in a number of circumstances.
