Embodiment Construction

[0048] As mentioned in the background technology, the traffic statistics scheme for P devices in the prior art has high requirements for operators, and relevant operators need to be familiar with the connection status of the live network, the basic principles of MPLS VPN, label distribution rules, routing, etc. Knowledge has a very deep understanding, which increases the cost of personnel input, and the corresponding operation process is also very cumbersome, which is not conducive to the popularization and promotion of related operation processes, and also increases the difficulty of operation.

[0049] In order to solve the above problems, the present invention proposes a traffic statistics method based on a private network VPN, which is applied to a system including multiple service provider devices, PE devices, CE devices and a traffic analysis server.

[0050] Among them, each PE device can add a private network label corresponding to the VPN to which the data flow belongs...

Abstract

The invention discloses a flow calculating method, a flow calculating device and a flow calculating system based on a private network VPN. On the basis of private VPN information, the flow is calculated and analyzed on a device of a service provider of an MPLS LSVPN network, so the invention solves the original problem of relying on administrator to manually deduct and calculate the flow, and enables the flow analysis to automatically complete by matching a flow analyzing server with the device, thereby enhancing the efficiency of the flow calculation, and lowering the labor cost.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a traffic statistics method, device and system based on private network VPN. Background technique [0002] Multiprotocol Label Switching L3 Virtual Private Networks (MPLS L3 VPN) is an L3VPN technology based on a provider edge router (Provider Edge, PE) in the service provider VPN solution, which uses border A gateway protocol (Border Gateway Protocol, BGP) advertises VPN routes on the service provider backbone network, and uses MPLS to forward VPN packets on the service provider backbone network. [0003] The MPLS L3VPN networking mode is flexible, has good scalability, and can easily support MPLS Service Quality (Quality of Service, QoS) and MPLS Traffic Engineering (Traffic Engineering, TE). Therefore, it has been applied more and more. [0004] The network traffic analysis system can provide network traffic information statistics and analysis functions for vari...
