Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] The technical scheme of the invention can be applied to the service chain technology under the network virtualization environment. The service chain technology is a technology for establishing a service function chain and forwarding data packets or data frames of the service flow through the service function chain. Among them, the business flow refers to the traffic from a specific user, and / or entering the business network from a specific access po...

Abstract

Disclosed are a method for generating forwarding information, a controller and a service forwarding entity. The method comprises: determining, by a controller, a first SFE and a second SFE which are used for forwarding a service flow, wherein the first SFE and the second SFE are on a service function chain corresponding to the service flow; generating, by the controller, first forwarding information for the first SFE, and generating second forwarding information for the second SFE; and sending, by the controller, the first forwarding information to the first SFE, and sending the second forwarding information to the second SFE. By means of the method for generating forwarding information, controller and service forwarding entity in the embodiments of the present invention, the flow direction of service flows can be comprehensively controlled by generating forwarding information for SFEs by a controller, thereby realizing the load sharing, so that the service chain technology can be suitable for a great deal of services and a service environment of a processing function unit for the great deal of service.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for generating forwarding information in the communication field, a controller and a service forwarding entity. Background technique [0002] At present, load sharing is usually based on quintuple information, such as performing a hash operation on the IP source address, IP destination address, protocol number, source port, and destination port in the quintuple. Export to different next-hop routing devices. Usually, this hash is pre-configured statically on network devices such as routers, and cannot be adjusted according to specific situations. [0003] With the increase of service types of operators, a more flexible service chain technology is proposed. This technology provides the basis for flexible business processing by linking multiple business processing functions. The service chain technology classifies the service flow through the service classifier (Service Classif...
