VIRTUAL LOCAL AREA NETWORK SERVER REDUNDANCY AND FAILOVER TO ENABLE SEAMLESS MOBILITY IN THE MOBILITY DOMAIN

摘要

A method, apparatus and computer program product for providing Virtual Local Area Network (VLAN) server redundancy is presented. A mobility switch (MS) advertises to at least one peer mobility switch, VLANs configured as server capable, the advertising including providing priority information relating to a server for the VLAN. The MS receives advertising from the at least one peer mobility switch and elects a server for a mobility VLAN which is not mapped locally. The MS maintains a current server and a list of alternative servers for the VLAN and determines when the MS looses connection with the current server for the VLAN and moves the VLAN to an alternate server contained on the list.
