Method and device for business traffic scheduling

Abstract

The present invention provides a method and device for business flow scheduling, including: establishing a tunnel, configuring the tunnel priority of the tunnel, adding the identifier of the tunnel with the same priority to the same ECMP group, and the priority of the tunnel is the priority of the ECMP group; Establish the corresponding relationship between service identification, service priority and tunnel priority; establish the first ACL entry, the first ACL entry contains the correspondence between service identification and service priority; establish the second ACL entry, the second ACL entry Contains the corresponding relationship between service priority and tunnel priority; find the corresponding first service priority from the first ACL entry according to the service identifier of the first service message; find the corresponding first service priority from the second ACL entry according to the first service priority The first tunnel priority; determining the ECMP group corresponding to the first tunnel priority according to the first tunnel priority; selecting the first tunnel from the ECMP group to send the first service message. Solve the problem that the chip needs to identify different service packet flows and consume a lot of forwarding table resources.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for business flow scheduling. Background technique [0002] In recent years, with the continuous development of Internet technologies such as cloud computing and big data, the scale of the data center network is also increasing, which puts forward higher requirements for the construction of the data center network of the ISP service provider. Effective management, improving network utilization, and reducing operating costs are issues that need to be resolved urgently. [0003] SR (segment routing) is an innovative network protocol based on source routing after the multi-protocol label switching protocol MPLS in the Ethernet field. Compared with the traditional MPLS mechanism, it has a simpler control plane and an easily expandable data plane. By pressing the segment identifier in the source routing node, the message forwarding path can be effectively planne...

Problems solved by technology

[0006] When the operator's network switch equipment needs to prioritize and forward service traffic, one way is to use policy routing. Instead, specify the exit directly (the exit may be a tunnel), which is more flexible. The disadvantage of this method is that the manual configuration method is prone to omissions and the workload is large, and it does not support ECMP (Equal-CostMultipath Routing). ), and it needs to consume more access control list ACL hardware resources
