Solved in 2 steps
- A router interconnects a subnet, where all the interfaces of the subnets must have the prefix 164.132.62/24. suppose that the Subnet is required to support up to 60 interfaces, provide a network address that satisfies the above.A router receives a packet with destination address 196.77.26.206 Show how it finds the network and the subnetwork address to route the packet. Assume the number of subnetworks required is four.A 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 1,500 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?
- 22. A datagram subnet allows routers to drop packets whenever they need to. The probability of a router discarding a packet is p. Consider the case of a source host connected to the source router, which is connected to the destination router, and then to the destination host. If either of the routers discards a packet, the source host eventually times out and tries again. If both host-router and router-router lines are counted as hops, what is the mean number of a. (a) hops a packet makes per transmission? b. (b) transmissions a packet makes? (c) hops required per received packet?4. A router receives a packet with destination address 196.77.26.206 Show how it finds the network and the subnetwork address to route the packet. Assume the number of subnetworks required is four. Please solve it using the keyboard, not using the hand, and quickly, and I hope that the solution is correct.22. A datagram subnet allows routers to drop packets whenever they need to.

- Data Communication Suppose that Router A and Router B are connected via a 0.05 Mbps link (note, 1 Mbps = 106 bps) and that the link connecting the two routers has a length of 80 meters. Suppose that Router A is in the process oftransmitting a packet, and that there are 15 additional packets in the queue of the router, when a new packet arrives at Router A. Assume the followinga. Every packet consists of 15,000 bits.b. 5000 bits of the currently-being-transmitted packet has been transmitted by Router A when the new packet arrives at Router A. c. Propagation speed of a bit over the link connecting the two routersis 2 ? 103 meters/sec.d. Processing delay of a packet at a router takes 1 millisecond (i.e., 0.001 seconds).What is the total delay of the new packet in arriving at Router B, i.e., how long does it take the new packet to arrive at Router B from the time it arrived at Router A? In your solution, clearly identify all four delay components the new packet experiences.1. A router receives a packet with destination address (please refer to the table attached to find the IP address) IP: 210.140.138.176 Show how it finds the network and the subnetwork address to route the packet. Assume the number of subnetwork required is four.1. A router receives a packet with destination address (please refer to the table attached to find the IP address) IP:213.35.120.200 Show how it finds the network and the subnetwork address to route the packet. Assume the number of subnetwork required is four.
- - Suppose a TCP message that contains 1024 bytes of data and 20 bytes of TCP header is passed to IP for delivery across two networks interconnected by a router (i.e., it travels from the source host to a router to the destination host). The first network has an MTU of 1024 bytes; the second has an MTU of 576 bytes. Each network's MTU gives the size of the largest IP datagram that can be carried in a link-layer frame. Give the sizes and offsets of the sequence of fragments delivered to the network layer at the destination host. Assume all IP headers are 20 bytes.hdet b) Consider sending a packet contains 1100 bits from Host A to Host B in a store and forward nerwork. There are 10 links (and 9 routers) between A and B, and the links are congested (there Is a queuing delays). Assume propagation delay over the links are negligible. As a packet travels along the route, it encounters an average of 5 packets already waiting in the queue to be transmitted when it arrives at each router, How long does it take for the packet to get to the receiver if the nodes transmit on a "first come first served" basis (in ms)?A workstation uses the HTTP protocol to download a large file from a web server. No proxy server is used. One router's queue is full when one of the web server's packets arrives.Select the four best statements to describe this situationa. The router stores the packet until such time that it can be sent.b. Further packets sent by the server are transmitted at a higher rate to compensate for the lost packet.c. The router sends an ICMP link congested message to the server.d. The packet must be retransmitted.e. Router configuration and network behavior could be improved by configuring FQ or WFQ.f. Further packets sent by the server are transmitted at a lower rate to reduce the load on the congested link.g. Router configuration and network behavior could be improved by configuring RED or WRED.h. A tail drop will happen.
