Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] refer to figure 1 , a method for implementing HQoS technology in a T-MPLS network, comprising the following steps:

[0044] S101: Construct the part under the root node of the HQoS policy tree of the device according to the networking environment of the network, and configure a scheduling policy for each flow classification node therein. The scheduling policy can be SP policy, WRED policy, WFQ policy and SHAPING policy a kind of; among them,

[0045] When the top layer HQoS policy of the HQoS policy tree is a 3-layer HQoS policy, according to the networking environment of the network, construct the lower part of the root node of the HQoS policy tree through the following steps:

[0046] 1. Create all 3-layer HQoS policies, 2-layer HQoS policies and 1-layer HQoS policies;

[0047] 2. Create a traffic classification node for the Layer 3 HQoS policy, and configu...

Abstract

A method for implementing HqoS technique in T-MPLS network comprises the following steps: achieving HqoS configuration of equipment according to networking environment of a network; and receiving a data stream by the equipment in the appointed direction of an appointed port, and scheduling the data stream layering according to the HQoS configuration. The method has the advantage that the method can achieve the application of HQoS technique in the T-MPLS network to provide better QoS capability in the T-MPLS network, thereby controlling the user traffic rate and scheduling the priority of the user's services.

Description

technical field [0001] The present invention relates to a method for implementing HQoS (Hierarchical Quality of Service, hierarchical quality of service) technology, in particular to the implementation of HQoS technology in a T-MPLS (TransferMulti-protocol Label Switching, transport layer multi-protocol label switching technology) network Implementation. Background technique [0002] MPLS (Multi-protocol Label Switching, multi-protocol label switching technology) is a forwarding mechanism, which is characterized in that it does not use IP address prefixes to search for matching items in the routing table when forwarding packets, but labels packets entering the MPLS domain with a very A short, fixed-length "tag". In this way, when forwarding a packet, it does not go up to the network layer, but uses the hardware to forward according to the label of the second layer, thus speeding up the speed of packet forwarding. Each interconnected device in the MPLS domain needs to use a...
