Problems solved by technology

When the operator cannot guarantee the 10M bandwidth service between CPE1 and CPE2, the data packet sent by terminal device 1 to terminal device 2 will be lost on the Ethernet dedicated line
Moreover, each forwarding device in the operator's network will not recognize the priority in the data packet, resulting in a high possibility of discarding the high-priority data packet, seriously affecting the high-priority service of the user, affecting the user's business experience

Embodiment Construction

[0020] Aiming at the problems existing in the prior art, a method for adjusting the egress bandwidth of QoS (Quality of Service) is proposed in the embodiment of the present invention. In the network of the peer CPE. In a network including the local CPE and the remote CPE, the user can rent the operator's Ethernet dedicated line (such as an Ethernet layer 2 leased line or an Ethernet layer 3 leased line), where the Ethernet leased line can be an MPLS leased line or SDH ( Synchronous Digital Hierarchy (Synchronous Digital Hierarchy) dedicated line, and in the MPLS network, the Ethernet dedicated line can usually be an MPLS dedicated line. At present, the core network and the backbone network of the operator generally adopt the MPLS VPN (Virtual Private Network, virtual private network) technology to provide Ethernet private lines to users. According to user needs, operators can generally divide the service of Ethernet leased lines into different levels such as gold, silver, an...

Abstract

The present invention provides a method and device for adjusting QoS egress bandwidth. The method includes: the local CPE periodically sends a detection message to the peer CPE through the Ethernet dedicated line; the local CPE receives the detection message from the peer CPE. Response message, the probe response message carries the number of probe messages received by the peer CPE within a preset time; The number of messages and the number of detection messages sent by the local CPE within the preset time determine the link quality of the Ethernet dedicated line; the local CPE uses the link quality of the Ethernet dedicated line to adjust the egress bandwidth of QoS. Through the technical scheme of the invention, the probability of packet loss of data messages on the dedicated Ethernet line can be reduced, and user service experience can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for adjusting QoS egress bandwidth. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of networking of an MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) network. For data packets sent from terminal device 1 to terminal device 2, data packets of different service types have different priorities. For example, the priority of the data packet of the video service is higher than that of the data packet of the webpage service. On CPE (Customer Premise Equipment, user end equipment) 1, data packets of different priorities are stored in queues of different priorities. For the egress bandwidth of CPE1, queues with different priorities occupy different scheduling weights of the egress bandwidth, and the scheduling weights occupied by high-priority queues are greater than those occupied by low-priority queues, thus ens...
