7210 SAS multipoint bandwidth management policies

Overview

A 7210 SAS Multipoint Bandwidth Management policy defines rate limits and burst sizes for multipoint queues, to balance flows with unicast traffic. The policy defines an aggregate rate for all multipoint traffic in the NE. Rates for individual queues are configured as a percentage of the aggregate rate.

In the 7210 SAS-X, SAP ingress and network ingress multipoint traffic is separated from unicast traffic and forwarded into multipoint queues before being replicated to the appropriate egress port. There are eight multipoint queues per NE, which are shared by all services. Packets are forwarded to multipoint queues based on the forwarding classes assigned during ingress. The FC-to-queue mapping is not user-configurable.

The NFM-P provides a default multipoint bandwidth management policy. The default policy is applied if no user-defined policy is explicitly assigned. The default policy specifies maximum rate and burst size settings. See the NE documentation for more information.
