Business configuration method and system under two layer-to-three layer business scene of PTN

Abstract

The invention discloses a business configuration method and system under a two layer-to-three layer business scene of a PTN and relates to the field of end-to-end network management of the PTN. The business configuration method includes steps that drawing a PTN business scene template and key nodes; configuring basic attribute parameters for two layer-to-three layer business; contrasting and classifying business nodes of mapping corresponding to the key nodes; automatically configuring tunnel parameters, two layer pseudo-wire parameters and three layer private network routing parameters, and calculating tunnel configuration data according to the mapping nodes and tunnel parameters; calculating two layer pseudo-wire configuration data according to the mapping nodes and two layer pseudo-wire parameters; calculating three layer private network routing configuration data according to the mapping nodes and three layer private network routing parameters. When using, the business configuration method under the two layer-to-three layer business scene of the PTN is easy to operate, fast in configuration, capable of improving the network maintenance efficiency, convenient for people to use, capable of lowering the configuration cost and broad in application range, and the requirements on a configuration operator are low.

Description

technical field [0001] The invention relates to the field of PTN (Packet Transport Network, packet transport network) end-to-end network management, and in particular to a service configuration method and system in a PTN layer-2 to layer-3 service scenario. Background technique [0002] PTN is a packet transport network based on optical transport network architecture, and PTN is mainly used for the backhaul of mobile or data services in communication networks. In communication networks (such as the networks of major telecom operators), the business scenarios used by PTN are generally as follows: the access layer adopts a two-layer network (data link layer), and the aggregation layer and core layer adopt a three-layer network (network layer). [0003] When PTN is used, various objects of Layer 2 network services (that is, Layer 2 services) and Layer 3 network services (that is, Layer 3 services) are configured using conventional static configuration methods respectively. def...

Problems solved by technology

[0004] (1) When a Layer 2 service needs to be transferred to a Layer 3 service, a large number of tunnels, pseudowires, private network routing information, and various protection parameters need to be manually configured, which makes the end-to-end service configuration process cumbersome and complex. Slow (the configuration process generally takes more than 30 minutes), the main
