Virtual local area network server redundancy and failover to enable seamless mobility in the mobility domain

A first mobility switch (MS) comprising:

• a memory;
• a processor;
• a communications interface;
• an interconnection mechanism coupling the memory, the processor and the communications interface;
• and
• wherein the memory is encoded with an application providing Virtual Local Area Network (VLAN) server redundancy, that when performed on the processor, provides a process for processing information, the process causing the first mobility switch to perform the operations of:
• advertising, by a first mobility switch (MS) to at least one peer mobility switch, VLANs configured as server capable, said advertising including providing priority information relating to a server for said VLAN;
• receiving advertising from said at least one peer mobility switch;
• electing a server for a mobility VLAN which is not mapped locally;
• maintaining a current server and a list of alternative servers for said VLAN;
• and
• determining when said first MS loses connection with said current server for said VLAN and moving said VLAN to an alternate server contained on said list.

A non-transitory computer readable storage medium having computer readable code thereon for providing Virtual Local Area Network (VLAN) server redundancy, the medium including instructions in which a computer system performs operations comprising:

• advertising, by a first mobility switch (MS) to at least one peer mobility switch, VLANs configured as server capable, said advertising including providing priority information relating to a server for said VLAN;
• receiving advertising from said at least one peer mobility switch;
• electing a server for a mobility VLAN which is not mapped locally;
• maintaining a current server and a list of alternative servers for said VLAN;
• and
• determining when said first MS loses connection with said current server for said VLAN and moving said VLAN to an alternate server contained on said list.
