Method and system for monitoring flow in MPLS-VPN (Multiple Protocol Label Switching-Virtual Private Network)

Abstract

The invention discloses a method and a system for monitoring flow in an MPLS-VPN (Multiple Protocol Label Switching-Virtual Private Network) and relates to the technical field of network information. The method for monitoring flow in the MPLS-VPN provided by the embodiment of the invention can automatically learn according to data, intelligently adjust a monitoring threshold and realize a flexible flow monitoring solution. The MPLS-VPN can be dynamically monitored through a base line, the manual configuration of the monitoring threshold by a network administrator can be reduced, and a software program can dynamically generate the monitoring threshold according to historical flow data. Not only can the labor input be greatly reduced, but also the flow monitoring of the MPLS-VPN can be more properly realized. The method and the system can be continuously improved and upgraded with service environments; since the new service environment and the network environment increasingly become complex and the situations of network environment change and network recombination become more and more, aiming at different service environments, the monitoring demand can be quickly satisfied.

Description

technical field [0001] The invention relates to the field of network information technology, in particular to a method and system for monitoring traffic in an MPLS-VPN (Multiprotocol Label Switching Protocol-Virtual Private) network. Background technique [0002] VPN is a virtual private network (Virtual Private Network), and its function is to establish a private network on a public network for encrypted communication. It is widely used in the network of large enterprises. [0003] MPLS-VPN refers to the use of MPLS (Multi-Protocol Label Switching Protocol) technology to build an enterprise IP private network on the backbone broadband IP network to achieve cross-regional, safe, high-speed, and reliable data, voice, and image multi-service communications, and to combine different Services, traffic engineering and other related technologies combine the reliable performance, good scalability, and rich functions of the public network with the security, flexibility, and efficie...

AI Technical Summary

Problems solved by technology

[0004] In the existing solution, in the MPLS-VPN network, the method of statically configuring the warning threshold is adopted for the monitoring of network traffic, and the configuration interval of the threshold value is judged entirely based on experience, which cannot adapt to the changes brought about by data changes and structural changes in the network. Invisible impact, there are factors of alarm and false alarm, which is not conducive to the rapid and timely monitoring and early warning of the current network situation
