Method and device for the multi-interface to realize the promised access speed

Abstract

The invention discloses a method and device for realizing the promised access rate via the multiple interfaces and belongs to the network communication area. The method includes: apply the quality policy of one server at multiple interfaces of one single board, the processing action of the service quality policy is used as the promised access rate, every interface of multiple interfaces is configured by one promised access rate, the promised access rate of every interface is the promised access rate of the service quality policy; when the packets are forwarded at every interface, the processing action is executed at the promised access speed at this interface. The device include: setting module and processing module. The invention overcomes the inaccurate promised access speed and realizes the accurate promised access speed at multiple interfaces when one processing action is applied to the multiple interfaces of single board as the promised access speed.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for realizing a committed access rate by multiple interfaces. Background technique [0002] Due to the burstiness of network traffic, the actual network bandwidth cannot meet the needs of all users under sudden conditions. In fact, network users' demand for bandwidth is endless. In addition, in addition to traditional services that are not sensitive to delay such as email, the current IP network also transmits more and more new services such as voice, multimedia, and VPN (Virtual Private Network) through the IP network. Services have higher requirements on bandwidth, delay, and delay jitter. [0003] The QoS (Quality of Service) of the network refers to the expected availability, throughput (bandwidth), delay, delay jitter, packet loss rate, etc. of the communication network under various circumstances. . In order to ensure the QoS of specific services,...

Problems solved by technology

[0009] For example, if a QoS policy stipulates that the action after complex traffic classification is CAR, and the rate is limited to 1000kbit / s, the upper layer software will send an entry to TCAM according to the complex traffic classification principle in the policy, and issue an action table and a car table, the car id in the action table can be indexed to the car table, and the value of the committed access rate in the car table is 1000kbit / s; when this strategy is applied to 10 interfaces of a single board at the same time When it is uploaded, the packets conforming to the classification principle in the policy forwarded through these 10 interfaces will all hit the same entry in TCAM and get the same return result. According to the return result, they will also be indexed to the same action table, and from The same car id is obtained in the table, and the same car table is read according to the car id, so as to obtain the value of the promised access rate of 1000kbit / s, and then the action of the promised access rate of 1000kbit / s is performed on these 10 interfaces, which is manifested in the macro On the other hand, the sum of the traffic matched by 10 interfaces is 1000kbit / s, instead of 1000kbit / s matched by each interface, which will cause the problem that the actual traffic does not match the promised access rate
