Difference between SCTP and UDP
1. Stream Control Transmission Protocol (SCTP): SCTP is a connection-oriented protocol in computer networks that provides full-duplex association i.e., Transmitting multiple streams of data between two endpoints at the same time that have been established connection in the network.
2. User Datagram Protocol (UDP): UDP is a Transport Layer protocol. UDP is a part of the Internet Protocol suite, referred to as UDP/IP suite. Unlike TCP, it is an unreliable and connection-less protocol. So, there is no need to establish a connection prior to data transfer. UDP sockets are an example of datagram sockets.
Difference Between SCTP and UDP:
|Parameter||SCTP Protocol||UDP Protocol|
|Reachability Check||We can have a reachability check-in SCTP.||There is no reachability check-in UDP.|
|Multistreaming||SCTP supports Multistreaming.||UDP doesn’t support Multistreaming.|
|Data Transfer||Data transfer is more reliable than SCTP.||There is no reliable Data transfer in UDP.|
|Selective ACKs||There are selective ACKs in SCTP.||There are no selective ACKs in UDP.|
|Multihoming||Multihoming is supported by SCTP.||UDP doesn’t support Multihoming.|
|Connection-oriented||SCTP protocol is connection-oriented.||UDP protocol is not connection-oriented.|
|Partial Data Transfer||There is Partial Data Transfer in SCTP.||There is no Partial Data Transfer in UDP.|
|Ordered Data Delivery||There is ordered data delivery in SCTP.||Ordered Data delivery is not supported by UDP.|
|Flow Control||SCTP has efficient flow control.||UDP has no efficient flow control.|
|Congestion Control||Congestion control in SCTP.||No congestion control in UDP.|
