DiffServ Standard IP-based networks are designed to provide "best effort" data delivery service. Best effort service implies that the network delivers the data in a timely fashion, although there is no guarantee that it will meet the latency or bandwidth requirements. During times of congestion, packets may be delayed, sent sporadically, or dropped. For typical Internet applications, such as email and file transfer, a slight degradation in service is acceptable and in many cases unnoticeable. Conversely, any degradation of service has undesirable effects on applications with strict timing requirements, such as voice or multimedia. Diffserv allows the network operator to classify and apply a distinguished service to traffic based on a number of criteria. The distinguished service can meter traffic and apply per hop behavior based upon the bandwidth utilization and burstiness of traffic. In addition, preferential drop characteristics can be configured in support of an assured forwarding capability such that TCP clients are informed if they exceed the switch buffering limits. assign-queue Use the assign-queue command in Policy-Class-Map Configuration mode to modify the queue ID to which the associated traffic stream is assigned. Syntax assign-queue queueid • queueid - Specifies a valid queue ID. (Range: integer from 0-6.) Default Configuration This command has no default configuration.
