Abstract

The embodiment of the invention provides a method and device for realizing load sharing of an access gateway. The method of the invention comprises the following steps: receiving an internet protocol security (IPsec) tunnel authentication request message comprising cache COOKIE information transmitted by a user terminal; determining a service processing module to be distributed by the user terminal according to the COOKIE information, and transmitting the IPsec tunnel authentication request message to the service processing module; and returning an IPsec tunnel authentication response message constructed by the service processing module to the user terminal, wherein the IPsec tunnel authentication response message comprises the identification of the service processing module distributed by the user terminal. By the method and device provided by the embodiment of the invention, the access gateway can realize uniform load sharing.

Description

technical field [0001] The invention relates to the network field, in particular to a method and device for load sharing by an access gateway. Background technique [0002] Currently, both ends of an IPsec (IP security) tunnel provide privacy, integrity, access control, and data source authentication services for IP (Internet Protocol, a protocol for interconnecting networks, referred to as Internet Protocol) messages through shared keys. The shared key can be established manually or automatically through negotiation. A key agreement mechanism—IKE (Internet Key Exchange, Internet Key Exchange) protocol is defined in RFC2407, RFC2408 and RFC2409. [0003] According to the IKE protocol, the initial interaction (INITIAL) establishes IKE_SA (Internet Key Exchange Security Association) and the first CHILD_SA (Child Security Association), that is, IPsec SA (IPSec Security Association). The process is as follows figure 1 shown. It consists of four messages: the first two message...
