Problems solved by technology

However, according to the traditional Netflow IP packet quintuple information (source / destination IP address, source / destination port number, and protocol number), it is impossible to count the data packet flows belonging to different VPNs, and it is also impossible to count the data packets from the same VPN to different remote PEs. Packet traffic of the device

Embodiment Construction

[0033] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0034] Utilizing the characteristics of Netflow V9 extensible templates, the present invention proposes a template format and sends it to the upper management server regularly, and the upper management server parses subsequent received data messages according to the data format defined by the template to achieve statistical VPN traffic Purpose of Information.

[0035] Before collecting the data stream flowing into the ingress PE, the ingress PE should be configured with parameters such as the Netflow message version (the present invention requires configuration V9 version), aging policy, etc., as well as the VPN routing table information. The corresponding relationship between the VPN ID of each access port and the ID of the remote PE is saved, and there is also a cache area on the ingress PE for caching the collected data packet infor...

Abstract

A method for acquiring and counting virtual private network VPN flow by using Netflow includes the following steps: VPN routing list information is configured on entrance service provider edge-node PE, wherein the corresponding relation with access port VPN identification and remote end PE identification is stored; expanded Netflow V9 template message carried with the VPN identification and remote end PE identification is sent to a top management server; the entrance PE samples the data flow flowing therethrough, corresponding VPN identification is obtained according to the access port of the data flow, the identification of remote-end PE is obtained and the data packet information obtained by sampling is buffered in the combined with the VPN routing list information; the data packet information is sent to the top management server after the sample message obtained by packaging according to the expanded Netflow V9 template; and the top management server analyzes the sample message according to the template message, and the VPN flow is counted.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for collecting and counting VPN (Virtual Private Network, virtual private network) traffic by using Netflow (standard defined by IETF RFC3954). Background technique [0002] In recent years, the rapid development of the Internet in the world and the rapid popularization of various applications have made it an indispensable information carrying tool in people's daily work and life. However, along with the normal application traffic of the Internet, all kinds of abnormal traffic on the network also follow, affecting the normal operation of the Internet and threatening the security and normal use of user hosts. [0003] From the perspective of network operation and management, it is necessary to manage and monitor the traffic in the network, charge according to the traffic, conduct in-depth analysis of the characteristics of Internet traffic, analyze the characteristics of...
