Consider this multihpop network running the 802.11 MAC protocol in ad-hoc mode (RTS-CTS-DATA-ACK) and a link speed of 1 Mbps: A === B === C === D Edges ‘===’ represent connectivity, so, for instance, nodes B and C can communicate with each other directly, but A and C cannot. All nodes are able to route packets on behalf of the other nodes and they employ store-and-forward to deliver packets to the destination. Suppose nodes A, B, and C have to send a lot of data frames to node D and have their link layer queue always full. What is the average data rate for A, B, and C assuming no DATA frames get lost due collisions? Explain your answer. Compare the data rates with the link rate

Consider a node called A that sends packets to an adjacent node called B. To control the packet flow to node B, node A employs a credit manager scheme in which parameters C=3(credits), C_max=4(credits) and \tao=6(msec), respectively. node A has an infinite buffer to temporarily store packets. When a packet arrives at node A, node A stores the packet at the bottom of the buffer. Node A also has a single server (transmitter). As soon as the server becomes idle, the server picks up a packet at the head of the buffer, if any, and serves the packet for packet transmission time T_p as far as there remains a credit. (The packet transmission time T_p = 4 (msec).) We observed the arrival times of the first 12 packets, denoted by aA(1)⋯A(12), which were as follows: n A(n) 1 0.5 msec 2 1.0 3 1.5 4 2.0 5 4.5 6 5.5 7 6.5 8 12.5 9 13.0 10 13.5 11 14.0 12 14.6 1. Let R(n) denote the departure time of the n th packet from the buffer for n∈{1,2,...}. Find R(n) for…

Task NW29. UDP is the simplest transport layer communication protocol. It contains a minimum amount of communication mechanisms. It is considered an unreliable protocol, and it is based on best-effort delivery services. UDP provides no acknowledgment mechanism, which means that the receiver does not send the acknowledgment for the received packet, and the sender also does not wait for the acknowledgment for the packet that it has sent. An end system sends 50 packets per second using the User Datagram Protocol (UDP) over a full duplex 100 Mbps Ethernet LAN connection. Each packet consists 1500B of Ethernet frame payload data. What is the throughput, when measured at the UDP layer? Task DS30
Suppose we have a web page which contains 10 objects including: a html main file, 8 jpg image, and a .mp3 background music. For simplicity, assume each of the 10 objects has a size of 4 Kbits and that each object can be completely transferred in one TCP packet. Furthermore, assume the round-trip time between the server and client is RTT= 250 ms, and the download rate is 1 Mbps. What will be the time it takes to complete transferring the web page running in the non-persistent mode? Total delay = ms
It is necessary to investigate connectionless protocols as a potential substitute for connection-based protocols.
Please explain VERY DETAILED this question After running Dijkstra's algorithm in a link state protocol, a router Xdetermines that the predecessor of A is Y, the predecessor of Z is X, and thepredecessor of Y is Z. What is the path from X to A? Ans: X->Z->Y->A
Create a spanning tree for the given topology. Label all ports with their status i.e. Root, designated or block. Note: STP link costs are shown in brackets
An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most signi cant bits are used as a network ID, and the 16 least signi cant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?
It would be interesting to compared the advantages of connectionless protocols vs connection-based protocols.
Suppose two hosts A and B are connected via a router R. The A-R link has infinite bandwidth; the R-B link can send one packet per second. R's queue is infinite. Load is to be measured as the number of packets per second sent from A to B. Sketch the throughput-versus-load and delay-versus-load graphs, or if a graph cannot be drawn, explain why. Would another way to measure load be more appropriate?
Compared to connection-based protocols, consider the benefits and drawbacks of connectionless protocols.
In a bit-oriented link-layer protocol, the start and end of a frame are each marked by a flag, which is a sequence of exactly 6 consecutive 1 bits. Bit stuffing is used during the rest of the frame: after sending 5 consecutive 1 bits, a 0 is added. The bits below contain an example frame, with the leftmost bit received first. The content of the frame is a sequence of bytes, sent most significant bit first. Put the values of the first four bytes of the frame content, in order, in the four answer boxes below. You may enter the values in either decimal (e.g. 76, 123) or hexadecimal (e.g. 2a, f7). 00101011111010001111110011100111110000111101111101010110100010010011111101101100100 57−240−123−229
