Abstract

The invention provides a storage method and device for a service chain, electronic equipment and a storage medium. The method comprises the following steps: acquiring a service path indicated by a service path identification number SPI; determining a plurality of target service paths according to the service path; and forwarding the plurality of target service paths to a plurality of service function forwarders (SFFs) respectively, so that the SFFs store the received target service paths respectively. According to the method, the storage space of the SFF can be saved, meanwhile, the control plane message interaction length between the SDN and the SFF is reduced, resources are saved, and the problem that the service path length of a service chain is limited is solved.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a storage method, device, electronic equipment and storage medium for service chaining. Background technique [0002] The service function chain (Service Function Chain, SFC) technology can realize that network traffic passes through various service functions (also called service functions) in a predetermined sequence required by service logic. [0003] In related technologies, the SDN (Software Defined Network, software-defined network) controller sends the complete service path represented by SPI (Service Function Path Identifier, service path identification number) to each SFF (Service Function Forwarder, service function forwarder ), so as to instruct the SFF to forward traffic according to the SP (ServicePath, service path). [0004] However, with the rapid development of the service chain network business, the number of SPIs has increased, and the number...
