Abstract

The invention discloses a method, device and system for generating a service path. The method includes the steps that a PCE receives path calculation request PCReq information sent by a PCC, and the PCReq information includes NFV functional demand information; the PCE generates the service path according to an NFVDB, and an NFV functional entity in accordance with the NFV functional demand information is on the service path. According to the embodiment, the method, device and system have the advantages that when a user service changes, the PCE obtains the NFV functional demand information in the PCReq information sent by the PCC, the service path, meeting the requirement for passing the requested NFV functional entity in the NFV functional demand information, is generated according to the NFVDB, and therefore the service path of a user is dynamically configured. Compared with the mode that the service path of the user is statically configured, configuration and maintenance difficulty is lowered.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for generating a service path. Background technique [0002] Traditional carrier networks include many dedicated hardware devices with different functions, such as firewall servers, load balancing servers, Network Address Translation (Net Address Translation, NAT) servers, and Domain Name System (Domain Name System, DNS) servers. In order to provide customers with personalized network services, operators usually need to plan, deploy and configure hardware devices located in different locations in the network. Due to the flexibility of network services, in order to adapt to various network services, this kind of pre-planned deployment and configuration becomes more and more complicated. In addition, when a new network service is provided, it may be necessary to integrate and deploy brand new hardware devices in the network to support the...
