User datagram protocol (UDP) provides connectionless and unreliable process-to-process communication. It is a transport layer protocol. UDP has less overhead and provides faster delivery of the packets. UDP packets are referred to as user datagrams.

Selective Repeat Protocol
Selective repeat protocol is a sliding window protocol that uses the concept of pipelining where multiple packets can be sent while the sender is waiting for the acknowledgement for the first sent packet. The selective repeat protocol manages error and flows control between the sender and receiver. In this section, we will discuss the need for selective repeat ARQ (Automatic … [Read more...] about Selective Repeat Protocol
Go-Back-N Protocol ARQ
Go-back N ARQ (Automatic Repeat Request)protocol is a practical implementation of the sliding window protocol. Well, there are two practical implementations of sliding window protocol, go-back-n and selective repeat. But in this section, we will be concentrating on the go-back-n protocol. Content: Go-Back-N Protocol Introduction Go-Back-N Definition Working with … [Read more...] about Go-Back-N Protocol ARQ
Transport Layer Services
Among the transport layer services, the most important is to provide end-to-end communication between the process running on a source host and the corresponding process running on the destination host. There may be several processes running on the source host at the same time and there may be several processes running on the destination host. It is the responsibility of the … [Read more...] about Transport Layer Services
Internet Group Management Protocol
Internet Group Management Protocol (IGMP) is a network layer protocol that supports multicasting. The main task of the IGMP protocol is of managing the membership of the hosts in a multicast group. IGMP protocol is applicable between the host (active member of a multicast group) and the multicast router. We have three versions of this IGMP protocol where the IGMPv3 is … [Read more...] about Internet Group Management Protocol
