Difference between SCTP and UDP
Last Updated :

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. |
