Abstract

The embodiment of the invention discloses a redirection method. The redirection method can guide redirection operation according to a redirection historical record in a negotiation process of an initiator so as to improve the negotiation efficiency. The method disclosed by the embodiment of the invention comprises the following steps: in the negotiation process of the initiator and an initial responding party, if the initiator is redirected to a first target responding party by the initial responding party, the initiator records corresponding redirection result information; when the initiator is negotiated with the initial responding party again, the initiator carries the redirection result information in a negotiation message so that the initial responding party can carry out redirection operation according to the redirection result information.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a redirection method and related equipment. Background technique [0002] During the negotiation process of two communication network elements (including the initiator and the responder), based on the load balancing of the responder or failure of the responder, the responder can initiate a redirection request to redirect the initiator to another responder , for the initiator to negotiate a new responder. [0003] Taking IPsec tunnel negotiation as an example, the RFC5685 protocol supports the IKE init / IKE AUTH / Information stage in IPsec tunnel negotiation. The target responder negotiates an IPsec tunnel. The following describes in detail part of the process of IPsec tunnel negotiation that supports redirection operations: [0004] 1) The initiator A sends an IKE_SA_INIT Request (IKE-Security-Association-Initial Request, Internet Key Exchange-Security Association-...
