Problems solved by technology

Therefore, a plurality of load balancing devices 270 must be set in the system, and each time a service chain passes through a value-added service device 280, it must first pass through the load balancing device 270 in front of the value-added service device 280, resulting in a waste of resources

Embodiment Construction

[0046] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0047] refer to image 3 , image 3 It is a schematic structural diagram of an embodiment of the service chain load balancing system of the present application. The service chain load balancing system in this embodiment includes: a coordination device 210 , a PCRF unit 220 , a controller 230 , an access device 240 , a flow classifier 250 , a forwarding device 260 and a value-adde...

Abstract

The invention discloses a method, devices and system for load balancing of a service chain. The method comprises the steps that a flow classification device receives a service chain selection and control policy sent by a PCRF unit; service flows corresponding to service chain identifiers are hashed through the flow classification device according to the number of hashing parts so as to obtain multiple trickles, the service chain identifiers and hashing factors are added to messages of the trickles, and different trickles correspond to different hashing factors; the messages of the trickles obtained after the service chain identifiers and the hashing factors are added are sent to a forwarding device. Through the mode, the load balancing function can be achieved and meanwhile the number of load balancing devices in the service chain is reduced.

Description

technical field [0001] This application relates to the field of communications, in particular to a service chain load balancing method and its device and system. Background technique [0002] In the prior art, see figure 1 A large number of value-added service devices are often connected in series between the access device 110 and the Internet 160, including: anti-virus device 120, application cache and acceleration device 130, firewall 140, and Network Address Translation (NAT, Network Address Translation) device 150, etc. Wait. After the user terminal accesses the network through the access device 110 , the generated data must pass through the antivirus device 120 , the application cache and acceleration device 130 , the firewall 140 and the network address translation device 150 in sequence. In actual use, some users may only sign up for antivirus services, while others may only need NAT. However, under existing technical conditions, all must pass through the antivirus...
