METHOD, DEVICE AND SYSTEM FOR DISASTER TOLERANCE BASED ON WIRELESS PACKET GATEWAYS

摘要

A method of disaster tolerance based on wireless packet gateways includes: when a primary wireless packet gateway is unavailable, a backup wireless packet gateway of the primary wireless packet gateway is selected based on the acquired information of the backup wireless packet gateway, a section of the address pool of which is the same as that of the primary wireless packet gateway; a path connection to the backup wireless packet gateway is set up. A wireless packet gateway device and a system for disaster tolerance based on wireless packet gateways are provided. The method provided by the embodiments of the present invention delivers a concrete embodiment to enable of disaster tolerance based on wireless packet gateways, which reduces network risk and improves the quality of service.
