|
Subnet Manager (Adaptive Routing) |
Added support for Adaptive Routing. Adaptive routing (AR) allows optimizing data traffic flow. The InfiniBand protocol uses multiple paths between any two points. 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. |
