Congestion 7oti*ication -T;C SCB7/
The ITP maintains AS and AS PC congestion levels.
IP side congestion level is (ased solely on ASP and S$ MateSCTP association congestion. SCB7s *rom ASPs are ignored.
T;CSCB7 re+orting (y the ITP is disa(led (y de*ault, and is
ena(led (y a glo(al con*ig command.T;CSCB7 are not sent *or an AS PC that is a local PC.
es+onse mode T;C is sent to the BPC o* the MS5.
SCB7 is sent to all active ASPs.
y de*ault, T;C is sent (ased on AS PC congestion status.Alternatively, T;C can (e sent (ased on AS congestion status.This mode is ena(led (y a glo(al con*ig command.
