Problems solved by technology

When using the IPSEC function to forward packets, usually the interface cannot be selected. Therefore, it is impossible to select a load-sharing interface with smaller traffic according to different traffic, so that the outbound interface traffic is more uniform.

Embodiment 1

[0034] Such as figure 1 As shown, this embodiment records a method for controlling IPSEC load sharing through traffic, including the following steps:

[0035] S1: The network device is configured with a load sharing interface group, and each load sharing interface group includes multiple load sharing interfaces;

[0036] S2: Configuring multiple IPSEC tunnels to bind to the load sharing interface group;

[0037] S3: According to the difference in traffic of each load-sharing interface in the load-sharing interface group, select the load-sharing interface with the smallest traffic to negotiate and establish a tunnel when creating a new connection.

[0038] Wherein, the step S3 is specifically:

[0039] S31: Perform routing search on the message, if the outbound interface of the message is found to be a load-sharing interface group (wherein, if the outbound interface of the message is not a load-sharing interface group, only one outbound interface is optional, then Just forwa...

Embodiment 2

[0055] Such as figure 2 As shown, this embodiment records a system for controlling IPSEC load sharing through traffic, including:

[0056] The network device 201 is configured to configure a load sharing interface group, and each load sharing interface group includes a plurality of load sharing interfaces;

[0057] Tunnel configuration module 202, configured to configure multiple IPSEC tunnels to be bound to the load sharing interface group;

[0058] The tunnel establishment module 203 is used for selecting the load sharing interface with the smallest traffic for negotiation and establishing a tunnel when creating a new connection according to the difference in traffic of each load sharing interface in the load sharing interface group.

[0059]The network device 201 is one of a firewall, a router and a switch.

[0060] The present invention configures the IPSEC tunnel on the load sharing group, and the interfaces in the group are different according to the traffic. When cre...

Abstract

The invention discloses a method for controlling internet protocol security (IPSEC) load sharing. The method comprises the following steps: S1, configuring load sharing interface groups on a network device, wherein each load sharing interface group comprises a plurality of load sharing interfaces; S2, configuring a plurality of IPSEC tunnels to be bound onto the load sharing interface groups; and S3, according to different flow of the load sharing interfaces in each load sharing interface group, choosing the load sharing interface with the smallest flow during new connection building for consulting to build the tunnels. Additionally, the invention further discloses a system for controlling IPSEC load sharing to achieve the method. By means of the method and system for controlling IPSEC load sharing, IPSEC and interface load sharing are perfectly combined, the aim of IPSEC interface load sharing is achieved, and outlet interface distribution is more flexible and even in flow.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for controlling IPSEC load sharing through traffic. Background technique [0002] Most of the current network devices are equipped with IPSEC function and traffic load sharing function. Interface traffic load balancing usually distributes the data flow with the same destination address to the load sharing interface as evenly as possible in the way of load sharing (the load sharing interface is greater than or equal to 2). At this time, the load sharing interface has a route to the same destination address, so it can be Send data to the same destination through two different interfaces. However, when using the IPSEC function to forward packets, usually the interface cannot be selected. Therefore, it is not possible to select a load-sharing interface with smaller traffic according to different traffic, so that the outbound interface traffic is mor...
