WebTCP is similar to GBN because both protocols have a limit on the number of unACK'd packets that the sender can send into the network. However, TCP is different from GBN because GBN requires the re-transmission of every unACK'd packet when packets are lost, but TCP only retransmits the oldest unACK'd one.

WebSelective Repeat Protocol (SRP) • Selective Repeat attempts to retransmit only those packets that are actually lost (due to errors) – Receiver must be able to accept packets out of order – Since receiver must release packets to higher layer in order, the receiver must be able to buffer some packets • Retransmission requests – Implicit WebJul 30, 2024 · Types of Sliding Window Protocols. The Sliding Window ARQ (Automatic Repeat reQuest) protocols are of two categories −. Go – Back – N ARQ. Go – Back – N ARQ provides for sending multiple frames before receiving the acknowledgment for the first frame.
