- Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.1.17/24. Also suppose that Subnet 1 is required to support up to 25 interfaces, Subnet 2 is to support up to 50 interfaces, and Subnet 3 is to support up to 75 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraintsarrow_forwardConsider the following network. A. Display router forwarding table A. such that all traffic for H3 is transmittedthrough interface 3. b. May you enter a transmission table on router A, in that all traffic from HI to host H3 is transmitted via interface 3, while all traffic from 112 to host H3 is transmitted via interface 42? (Hint: This issue is a trick.)arrow_forwardA packet switch receives a packet and determines the outbound link to which the packet should be forwarded. When the packet arrives, one other packet is halfway done being transmitted on this outbound link and four other packets are waiting to be transmitted. Packets are transmitted in order of arrival. Suppose all packets are 1,200 bytes and the link rate is 2 Mbps. What is the queuing delay for the packet? More generally, what is the queuing delay when all packets have length L, the transmission rate is R, x bits of the currently-being-transmitted packet have been transmitted, and n packets are already in the queue?arrow_forward
- Consider a router buffer preceding an outbound link. In this problem, you will use Little’s formula, a famous formula from queuing theory. Let N denote the average number of packets in the buffer plus the packet being transmitted. Let a denote the rate of packets arriving at the link. Let d denote the average total delay (i.e., the queuing delay plus the transmission delay) experienced by a packet. Little’s formula is N=a⋅d . Suppose that on average, the buffer contains 10 packets, and the average packet queuing delay is 10 msec. The link’s transmission rate is 100 packets/sec. Using Little’s formula, what is the average packet arrival rate, assuming there is no packet loss?arrow_forward1. Consider a path from host A to host B through a router X as follows: A- -X-B The capacity of the link AX is denoted Ra, while the capacity of the link XB is denoted Rb in units of [bits/s]. Assume that Ra Ri. Is it possible that the second packet queues at input queue of the second link? Explain. Now suppose that host A sends the second packet T seconds after sending the first packet. How large must T be to ensure no queueing before the second link? Explain.arrow_forwardEach 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.arrow_forward
- Consider sending a 3500-byte datagram that has arrived at a router R₁ that needs to be sent over a link that has an MTU size of 1000 bytes to R2. Then it has to traverse a link with an MTU of 600 bytes. Let the identification number of the original datagram be 465. How many fragments are delivered at the destination? Show the parameters associated with each of these fragments.arrow_forwardConsider a computer 1 that communicates with a computer 2 via LAN1, router R1, and LAN2. The sending computer1 is running two processes at this time with port addresses k and l. The receiving computer 2 is running three processes at this time with port addresses f, g and h. Process k in the sending computer 1 needs to communicate with process g in the receiving computer 2. Draw the network and show the contents of segments, packets and frames at the network, data link, and transport layer for each hop. Note: Computer 1 has: Physical address=15, Logical address=A Router R1 has: Physical address in the side of LAN 1=20, Logical address in the side of LAN1=B Physical address in the side of LAN 2=50, Logical address in the side of LAN2=D. Computer 2 has: Physical address=77, Logical address=E.arrow_forwardConsider a router that interconnects four subnets: Subnet 1, Subnet 2, Subnet 3, and Subnet 4. Suppose all of the interfaces in each of these four subnets are required to have the prefix 223.1.17/24.Also suppose that Subnet 1 is required to support at least 90 interfaces, Subnet 2 is to support at least 60 interfaces, Subnet 3 is to support at least 13 interfaces, and Subnet 4 is to support 2 WAN interfaces. Provide four network addresses (of the form a.b.c.d/x) that satisfy these constraints. Also, justify your answer.arrow_forward
- A router has the following four active flows, and each flow has packets to transmit. Given FQ is being used on the router, what is the order that the packets will be transmitted?arrow_forwardQUESTION 77 Consider the network topology shown below with routers labeled A through F, inclusive. Each link is labeled with its "cost" for routing purposes. The link state routing algorithm is used in this network. (a)Show how Djikstra's algorithm works to compute paths from Router E to all other routers (show your answer in a table format similar to the one used in the lectures). (b)Show the final forwarding table at Router E after completion of the algorithm.arrow_forwardProblem 2. Consider a packet of L bits that is sent over a path of Q links (i.e., a source and destination connected by a sequence of (Q-1) routers or switches). Each link transmits at R bps. This packet is the only traffic transmitted by the network (so there are no queuing delays) and the propagation delay and processing delay at routers are negligible. How long does it take to send this packet from source to destination if the network is: a) a packet-switched datagram network b) a circuit-switched network. Assume that bandwidth of R bps on each link is sliced into five individual circuits, so that cach circuit receives (R/5) bandwidth. Also assume that the circuit setup time is t,.. Give an expression for the number of links Q such that the packet delivery from the sender to the receiver will be faster over the packet-switched network, and the expression for the number of links Q such that the circuit-switched network will be faster.arrow_forward
