Abstract
A method for avoiding IKE process conflict includes the steps in that a first gateway sends a first IKE request packet and receives a second IKE request packet from a second gateway. Afterward a decision is performed to decide whether the first gateway is an initiator or a responder. If the first gateway is an initiator, the first gateway will drop the received second IKE request packets and continue working as an initiator. If the first gateway is a responder, then first gateway will cancel the pre-sent first IKE request packet and work as a responder, and will perform IKE negotiation according to the second IKE packet. The present invention also discloses an apparatus for realizing above method.
Claims9
A method for avoiding IKE process conflict, comprising steps of:
- a first gateway sending a first IKE request packet and receiving a second IKE request packet from a second gateway;
- performing a decision step to determine the first gateway to be one of an initiator and a responder;
- the first gateway dropping the second IKE request packet and functioning as the initiator when the first gateway is determined to be the initiator;
- and
- the first gateway canceling the first IKE request packet and functioning as the responder when the first gateway is determined to be the responder, the first gateway performing IKE communication in response to the second IKE request packet.
An apparatus for avoiding IKE process conflict comprising:
- a first gateway sending a first IKE request packet;
- a second gateway sending a second IKE request packet;
- a controller configured for performing a decision step to determine the first gateway to be one of an initiator and a responder;
- wherein the first gateway drops the second IKE request packet and functions as the initiator when the first gateway is determined to be the initiator;
- and
- wherein the first gateway cancels the first IKE request packet and functions as the responder when the first gateway is determined to be the responder, the first gateway performing IKE communication in response to the second IKE request packet.
