ESWAN Destination-Based Regulation
Recovery Behavior
Congested node marks all RT-packets with CE until
node realizes sufficient decrease in arriving BW.
DST nodes having (d > d1) will issue regulate message.
Other DST nodes wait for time T. If packets keep
arriving with CE, nodes having (d > d2) will regulate.
After another time T, if packets keep arriving with CE,
nodes having (d > d3) will regulate.
Values (di) are network constants, and (di > di+1).
