What is Multihoming in SCTP?
First we will understand multihoming so multihoming is the process of connecting a network or a host to multiple network simultaneously which is done due to increase reliability or performance.
Telecommunication systems are highly prone to time delays. Multihoming system enables with multiple interfaces to use one over the other without waiting. SCTP multihoming means that the endpoints which are connected can have different IP addresses associated to it. In simpler way multihoming refers to sending data to an alternate IP address if in case due to any issue the primary or original IP address is unreachable. Therefore the SCTP can connect or establish multiple connection paths between two endpoints.
In this there is a original or primary interface or secondary interfaces. So during establishment of connections a acknowledgment process validates the IP address and manages the round trip time (RTT) for each individual address. The RTT calculation enables the communication to migrate to a secondary interface.
Stream Control Transmission Protocol (SCTP)
Stream Control Transmission Protocol (SCTP) is a network protocol that is connection-oriented and used for transmitting multiple streams of data simultaneously between any two endpoints that have established a connection in a computer network. SCTP is a transport layer of Internet Protocol (IP).
SCTP support telephone connection over the internet.
