2.24 Support for M2PA Busy Link

vSTP supports the M2PA busy link functionality based on the local received window accumulation size.

This functionality provides the capability to send busy links over M2PA link to the peer nodes when SCTP receives the window accumulation size that exceeds predefined thresholds depending upon Reserved TPS, MAXTPS , T7 value, and current receive window size. The functionality also allows to enable SCTP bundling per connection at vSTP.

The Link busy start threshold is calculated considering t7 timer value and receive queue size.
