Embodiment Construction

[0042] The inventive concept of the present invention is: after the connection is established between PE routers, when the first PE router receives the data packet, it adds a field dedicated to QoS mapping in the header of the data packet, and according to the QoS policy and the flow label in the packet header, Modify the content of the newly added field to a preset value, the preset value corresponds to one or more QoS processing, the first PE router sends the processed data packet; the second PE router receives After the data packet sent by the PE router, for the data packet containing the field dedicated to QoS mapping, perform corresponding QoS processing on the data packet according to the content of the field.

[0043] Modifying the content of the newly added field to a preset value according to the QoS policy and the flow label means: according to the QoS policy, it is determined which QoS processing is performed on which data packets in which data streams, and the newly...

Abstract

The invention discloses a QoS realization method in the transitional environment and a PE router, relating to the technical field of the router in communication network. The method in the invention comprises the following steps: adding a field dedicated to QoS mapping at a data packet header after the data packet is received by a first PE router and after connection is established between the PE routers; modifying the content of the newly-added field to be the preset value according to the QoS strategy and a flow label in the data packet header, wherein, the preset value is corresponding to one or a plurality of QoS processing; transmitting the modified data packet by the first PE router; carrying out corresponding QoS processing on the data packet which contains the field dedicated to the QoS mapping according to the content of the field by a second PE router after the second PE router receives the data packet transmitted from the first PE router. The technique in the technical scheme of the invention is simple and feasible, and is flexible and convenient to manage for carriers.

Description

technical field [0001] The present invention relates to the technical field of the router in the communication network, relate in particular to a kind of QoS realization in transitional environment in IPv6 (Internet Protocol version 6, Internet protocol version 6) technology and QoS (Quality of Service, quality of service) technology methods and PE routers. Background technique [0002] In the future IPv6 environment, the number of service traffic types on the existing network will further increase, and various new data types including 3G will emerge in an endless stream. It is bound to be one of the research focuses of operators to conveniently realize the management, maintenance and QoS differentiated processing of traffic of different user classes or different service traffic of the same user class. The IPv6 data packet header includes two main QoS fields, traffic class (traffic category) and flow label (flow label), where traffic class is used to distinguish different u...
