Coordinated environment for classification and control of network traffic

Suresh Muppala

- 20 Dec 2004

TL;DR: In this article, the authors proposed a coordinated network environment for traffic classification where an upstream network device classifies a data flow and adds traffic class information to at least one packet in the data flow.

Method and Apparatus for Out-of-Order Processing of Packets using Linked Lists

Edmund G. Chen, +3 more

- 24 Mar 2008

TL;DR: In this article, a method and apparatus for out-of-order processing of packets using linked lists is described, which includes receiving packets in a global order, the packets being designated for different ones of a plurality of reorder contexts, maintaining a reorder context linked list that records the order in which those of the packets that were designated for that re-order context and that are currently stored in the shared reorder buffer were received relative to the global order.

System and method for packet classification, modification and forwarding

Sean F. Nazareth, +5 more

- 29 Jan 2008

TL;DR: In this paper, a system may include a processor that is arranged and configured to receive initial data packets from a data stream, to classify the initial data packet from the data stream and to populate one or more tables with information based on the classification of the data packet.

Packet processing system including a policy engine having a classification unit

Charles E. Narad, +5 more

- 15 Jun 1998

TL;DR: In this article, a general-purpose programmable packet-processing platform for accelerating network infrastructure applications which have been structured so as to separate the stages of classification and action is presented, where a language interface is defined for specifying both stateless and stateful classification of packets and to associate actions with classification results.

Router device and network system using the same

Hidehiro Fukushima, +3 more

- 06 Jun 1997

TL;DR: In this paper, a router device determines a communication quality required by the communication of the packet in reference to a protocol information, an application acknowledging information and a priority information, transmits the control packet having the determined communication quality set therein to another router device contained in the same connection, and further performs a traffic control (a preferential processing of a packet or the like) satisfying a communications quality indicated by the transmitted or received control packet in respect to the packet of the aforesaid connection.
