Thus, when unexpected traffic patterns cause some paths to be overloaded, AR can automatically move traffic to less congested paths according to the current temporal state of the network. |
Adaptive Routing | Added support for Private Linear Forwarding Tables (PLFT). This capability helps SM to optimize traffic. |
