Abstract

The invention provides a tunnel identifier conversion method and device. The method comprises the following steps of: receiving a control message from VPN equipment, wherein an IP address of the VPN equipment and a first tunnel identifier are carried in the control message; obtaining an equipment identifier corresponding to the IP address of the VPN equipment, and obtaining a node identifier of the smallest available node according to a pre-set rule; obtaining a second tunnel identifier according to the equipment identifier and the node identifier; and replacing the first tunnel identifier in the control message by the second tunnel identifier, and forwarding the control message to a client side. Due to application of the embodiment, for different VPN equipment, even the first tunnel identifiers appointed by two client sides are same, the obtained second tunnel identifiers are also different because both the equipment identifier and the node identifier are different; therefore, the two client sides can be distinguished by load balancing equipment; and thus, normal services of the client sides can be ensured.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a method and device for converting a tunnel ID. Background technique [0002] VPN (Virtual Private Network, virtual private network) equipment is used to establish a private network in a public network for encrypted communication. In practical applications, in order to meet the concurrent online requirements of multiple clients, multiple VPN devices need to be used. When the client accesses the VPN service, the access request packet is sent to the load balancing device. The load balancing device is the client's The access request message is allocated to a VPN device, and the access request message is sent to the allocated VPN device. The VPN device allocates a tunnel ID for the access request message, and returns the tunnel ID to the VPN device through the load balancing device. The client, the load balancing device adds the tunnel identifier and the devi...
