1000 nodes are connected to a 1,5 km length of coaxial cable. Using some protocol, each node can transmit 50 frames/second, where the average frame length is 100000 bits. The transmission rate at each node is 100 Mbps (where 100Gbps). What is the efficiency of this protocol?(10 pts)
Homework Answers
Frame length = 100000
no.of node = 1000
Transmission rate = 100Gbps= 100×109bps
So bit transmitted by 1000 node = 50×100000×1000
= 50×108 bps
efficiency protocall = 50×108/100×109
= 0.05
% efficiency = 5%

Consider a 1-Mbps satellite channel. Frame length is 1000 bits and the probability of an unsuccessfiul frame transmission is P. Assume that the errors on different frames are independent. Neglect acknowledgment transmission time and receiver processing time and assume a sliding window protocol, using the selective-repeat ARQ method of error recovery. Assume t-50x10° seconds (a) What is the average number of transmission per frame N Assume P 0.01...

(a) A data link with a 1 Gigabits/sec capacity is used to transmit packets made up of 1400 bytes of data and 100 bytes of protocol control information. Each packet is acknowledged by a short frame of size 150 bytes. The propagation speed in the transmission medium is 200,000 km/sec. Consider the buffering and processing time in the nodes to be negligible. A node A communicates with a node B, with a distance between nodes A and B of 16...

Please Answer all Questions on Networks, They all involve calculation ( 1-9 Questions) "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second...
