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. |
