Abstract

The application provides a service traffic statistical method in an IPSec VPN tunnel. The method comprises the following steps: performing encryption / decryption processing on a service data message according to parameters in a preset SA policy when service data message passes through the IPSec VPN tunnel, wherein the encryption / decryption processing comprises encryption processing or decryption processing; and recording the number of byte of the service data message encrypted or decrypted each time.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for counting service traffic in an IPSec VPN tunnel. Background technique [0002] With the improvement of enterprise informatization, the information exchange between branches, offices and enterprise headquarters in various places, and the information transmission between enterprises and customers, the VPN technology based on IPSec protocol is widely used. During the application of IPSec VPN technology, it is necessary to monitor the business traffic and observe the size of the traffic passing through the IPSec VPN tunnel in real time, which requires statistics on the traffic passing through the IPSec VPN tunnel. Especially for frame-type devices (composed of one or two main control boards and multiple business cards, the main control board handles control requests, and the business card handles business data requests, and the boards ar...
