On the Passport 1600 Series switch, traffic prioritization allows you to manage bandwidth allocation for traffic flows on the LAN. These traffic flows are switched and routed in hardware at Layer 2 level. At the Layer 3 level, traffic flows on the LAN are routed at through a differentiated services (DiffServ) network architecture.
Traffic filtering is a mechanism that helps you to manage traffic by defining filtering conditions and associating these conditions with specific actions. Within a DiffServ network IP filtering allows you to assign QoS levels based on a range of filtering conditions.
Within the DiffServ network, the marked packets are placed in a queue according to their marking. For example, if a video stream is marked to receive the highest priority, it is placed in a high-priority queue. As those packets traverse the DiffServ network, the video stream is forwarded before any other packets.
