SCTP Multi-Homing

In this function, an SCTP association can support multiple pairs of IP addresses, providing multiple paths. Different paths are borne over different bearer planes to provide backup and improve reliability. At present, an SCTP association of the MSOFTX3000 supports two pairs of IP addresses (two local IP addresses and two peer IP addresses) and provides two paths. The active path is formed by local IP address 1 and peer IP address 1. Normally, the data is sent over the active path. The data is sent over the standby path only when the active path is inaccessible. After the active path is restored, the data is sent over the active path.
