WebAug 5, 2024 · b. With GBN, it is possible for the sender to receive an ACK for a packet that falls outside of its current window. c. The alternating-bit protocol is the same as the SR protocol with a sender and receiver window size of 1. d. The alternating-bit protocol is the same as the GBN protocol with a sender and receiver window size of 1. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
WebThe ACK number, like NAK (negative acknowledgement) number, shows the number of the frame, that receiver expects to be the next in sequence. The window size of the receiver is 1 as the data link layer only require the frame which it has to send next to the network layer. The sender window size is equal to ‘w’.

The sliding window (pipelined) protocols achieve utilization of network bandwidth by not requiring the sender to wait for an acknowledgment before sending another … See more Go-Back-N and Selective Repeat protocols are fundamental sliding window protocols that help us better understand the key idea behind reliable data transfer in the transport layer … See more As we stated before, pipelined protocols are an improvement over the stop-and-wait protocol. To achieve better network utilization, we have multiple frames “in-flight” between the sender and the receiver at a given time. … See more The Go-Back-N protocol adopts the use of cumulative acknowledgments. That is, receiving acknowledgment for frame means the frames , , and so on are acknowledged as … See more To sum up, the Go-Back-N protocol works for both the sender and the receiver side to ensure reliable data transfer.
