A classification mechanism automatically aligns time-sensitive data streams to sequences
(schedules), according to information in the packets or other information and classification …

Methods and systems for controlling scheduling in a packet switching node in a network are
provided which enable the scheduling of packets from different sources in an earliest …

Methods and systems for managing network traffic by mul tiple constraints are provided. A
received network packet is assigned to multiple queues where each queue is associated …

Abstract Systems and methods are described that provide network traffic engineering that

The problems outlined above may at least in part be Solved in Some embodiments by
prioritizing packets based on the urgency of processing them. Packets that are classi fied as …

This disclosure relates to methods and systems for queuing traffic in packet-switched
networks. In one of many possible embodiments, a queue management system includes a …

Streams of packets are dynamically switched among dedicated and shared queues. For
example, when a packet stream is in a maintenance mode (such as to keep a tunnel or …

(57) ABSTRACT A packet-based traffic shaping system including a scheduler that forwards
packets in accordance with a scheduling algorithm from queues that have at least a …

Methods and system for directing traffic flows to a fast data path or a slow data path are
disclosed. Parsers can produce packet header vectors (PHVs) for use in match-action units …
