Safe multiple tunnel method using internet protocol and three-layer equipment thereof

Abstract

This invention discloses a technological plan for using safety multiple tunnels of Internet protocol, which determines an effective IPSEC tunnel as the master one from multiple IPSEC tunnels with a same source and a destinated segment to transmit messages between the source and the destinated segment via the master IPSEC tunnel to realize the aim of using configured IPSEC multiple tunnels on the three-layer devices, besides, after the current IPSEC tunnel is faulty, one master tunnel is decided again from the multiple tunnels, so backup can be realized among multiple tunnles of IPSec.

Description

technical field [0001] The invention relates to Internet protocol security (IPSEC, IP Security) technology, especially a method and three-layer equipment using Internet protocol security multi-tunnel. Background technique [0002] With the massive popularization of the network, the network has become an indispensable part of people's production and life. However, with the continuous expansion of network applications, the importance of network security becomes higher and higher. IPSec is a three-layer tunnel encryption protocol formulated by the Internet Engineering Task Force (IETF), which provides high-quality, interoperable, and cryptography-based security guarantees for data transmitted on the Internet. [0003] Referring to FIG. 1 , FIG. 1 is a schematic diagram of a network structure in which IPSEC multi-tunnel exists in the prior art. IPSEC multi-tunnel refers to multiple IPSEC tunnels connecting the same source network segment and destination network segment. As sh...

Problems solved by technology

Therefore, in the prior art, the router cannot effectively use the IPSEC multi-tunnel configured by itself, which wastes system resources and makes the configured IPSEC multi-tunnel not effectively utilized
