Read MoreDifference Between Go-Back-N and Selective Repeat Protocol
Go-Back-N is a data link layer protocol that uses a sliding window method for reliable and sequential delivery of data frames. It is a case of sliding window protocol having to send window size of N and receiving window size of 1.Selective Repeat Protocol is also a data link layer protocol that uses sliding window method for reliable delivery of data frames. Here, only the erroneous or lost frames are retransmitted, while the good frames are received and buffered.Read through this article to find out how these two data link layer protocols work and what are the major differences between ...
Read MoreDifference between stateless and stateful protocols
A stateless protocol is one in which each communication is treated as a separate event, unrelated to other communications of the same type.A stateful protocol, on the other hand, is the polar opposite of a stateless protocol, in which each communication is treated as part of a broader sequence.Read through this article to find out more about stateless and stateful protocols and how they are different from each other.What is Stateful Protocol?In Stateful Protocol, when a client sends a request to the server, it expects a response; it resends the request if it does not receive one.Stateful applications and procedures ...
