Question

consider the latency for dynamic congestion windows. however, this discussion implicitly assumes that the sender and receiver are separated by a single network link. reconsider the analysis for dynamic congestion windows that we presented in lecture, assuming instead that there are n links between sender and receiver for sending an object of b bytes, split into segments of s bytes. specifically, give expressions for the number of server stalls as well as the total latency. in this analysis, use rtt as the total propagation latency on the round-trip path. to simplify this analysis, you may assume that there is no congestion in the network (i.e., no queuing delays), and all network links have the same transmission speed of r bytes/second. you may also ignore any processing delays.

Answer 1

The question is related to computer networking, where the expressions for the number of server stalls and total latency are derived considering a network with multiple links and a dynamic congestion window, assuming no congestion and a consistent RTT.

Step-by-step explanation:

The correct answer is option Computers and Technology, and the question pertains to the field of computer networking. When considering a network with n links, each having the same transmission speed of r bytes/second, and an object of size b bytes is divided into segments of s bytes, the number of server stalls and total latency can be analyzed assuming a round-trip time (RTT) that includes the propagation delay of all links.

The number of segments that need to be sent is b/s and each segment will experience an RTT before the acknowledgment is received. For the total latency, we need to consider the time taken to send all the segments, including the propagation delay for each link. With no server stalls due to no congestion, the total latency would primarily involve the sending and acknowledgment of each of the segments across the n links.

The correct answer is that the number of server stalls can be calculated by dividing the number of segments by the number of links (n) between the sender and the receiver. This can be represented by the equation s/n. The total latency can be calculated by adding the time it takes to transmit all the segments (b/s) to the round-trip time (rtt). This can be represented by the equation (b/s) + rtt.
