Problems solved by technology

[0003] However, in the prior art, IPSEC data packets are only distributed through IP quintuples, and the fineness is not enough, which may easily lead to a large amount of data in a data stream, resulting in too much load on the link transmitting the data stream, seriously affecting machine performance

Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] figure 1 It is a flow chart of a method for load sharing IPSEC data packets according to an embodiment of the present invention, and the method of the embodiment includes the following steps:

[0027] S1: Receive the current IPSEC data packet sent from the internal network to the external network;

[0028] S2: Search the routing table according to the IP destination address of the current IPSEC data message to obtain the corresponding exit of the current IPSEC data message, and determine whether the exit has a routing load sharing function, and if so, perform step S3, the The routing load sharing function is that the exit corresponds to a plurality of external net...

Abstract

The invention discloses a load sharing method and system for an IPSEC (Internet Protocol Security) data message, belonging to the technical field of network communication. The load sharing method comprises the following steps of: S1, receiving a current IPSEC data message sent by an intranet to an extranet; S2, searching a route list to obtain an exit corresponding to the current IPSEC data message, and judging whether the outlet has a load sharing function or not; and if the outlet has the load sharing function, executing step S3; and S3, classifying the IPSEC data message with same IP (Internet Protocol) five-element group and safe parameter index as a same data stream, and sending the message of the same data stream through the same extranet entrance, so as to share a load. According to the load sharing method and system provided by the invention, the IPSEC data message is branched by using the IP five-element group and the safe parameter index, and data are sent according to a branching result, so that the precision of branching the IPSEC data message and the properties of the entire machine can be improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for load sharing IPSEC data packets. Background technique [0002] At present, people's work, entertainment and other activities have higher and higher requirements on the reliability and stability of the network. Generally, the intranet in the occasion with higher requirements has two links with different operators (for example, China Unicom's external network and China Telecom Internet Protocol Security (IPSEC) data packets of network devices are usually used in two ways, load sharing by flow and load sharing by packet, but in order to prevent The out-of-sequence of packets, in some occasions that require high data transmission, usually adopts the method of load sharing according to the flow, and the processing process is generally as follows: firstly divide the packets Whether the IP quintuples of the text are the same to determine whether it...
