Unifying Local and Mobility Network Identifiers
First Claim
1. A method of transporting mobility traffic comprising:
- receiving a packet frame from a mobile device, the packet frame having a mobility network identifier;
mapping, at a mobility switch configured for routing wired message traffic and mobility message traffic, the mobility network identifier to a wired network identifier, the mobility message traffic defined by a wireless link to the mobile device;
determining, from the mapping, the wired network identifier corresponding to the user of the mobile device; and
forwarding, based on the determined wired network identifier, the packet frame, the forwarded packet frame transported via the mapped wired network identifier.

Abstract
In a mobility domain providing wired and wireless network transport to an enterprise or campus environment, a mobility switch maps a logical network identifier, such as a VLAN ID, to a “home” or wired network VLAN ID so that a mobile device is mapped to the wired VLAN for user identification, IP address consistency, and network policy enforcement. Propagation of the mapping to mobility switches ensures that a roaming user is mapped to the wired network VLAN from a remote L2 switch, and mobility tunnels across L3 boundaries allow roaming into a different broadcast domain or L3 switch connectivity in the mobility domain. Users are assigned to mobility VLAN(s) which are mapped to a VLAN in the wired domain at a mobility switch. The wireless users can roam within the wireless enterprise, or mobility domain, and the network maintains access to the user assigned mobility VLAN(s).

12. A mobility switch comprising:
-
a wired interface to a network device, the network device corresponding to a user; a wired network identifier corresponding to the network device, a mobility interface to a mobile device, the mobile device corresponding to the same user as the network device; a mobility network identifier corresponding to the mobile device; and a mapping from mobility network identifiers to wired network identifiers, the mapping configured to determine the wired network identifier corresponding to a packet frame emanating from the mobility device assigned the mobility network identifier, and further configured for forwarding, based on the determined wired network identifier, the packet frame, the forwarded packet frame transported via the mapped wired network identifier. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A computer program product having computer program code encoded as a set of instructions on a non-transient computer readable storage medium that, when executed by a processor, cause the computer to perform a method for managing a split-plane wireless network, the method comprising:
-
receiving a packet frame from a mobile device, the packet frame having a mobility network identifier; mapping, at a mobility switch configured for routing wired message traffic and mobility message traffic, the mobility network identifier to a wired network identifier, the mobility message traffic defined by a wireless link to the mobile device; determining, from the mapping, the wired network identifier corresponding to the user of the mobile device; and forwarding, based on the determined wired network identifier, the packet frame, the forwarded packet frame transported via the mapped wired network identifier.
