Embodiments herein include systems and methods for providing a mechanism to enable smooth, seamless, and reliable connectivity for wireless devices in a unified network. The system supports roaming of mobile units across mobility switches. A given mobile unit can retain its IP address in both intra-subnet and inter-subnet roaming scenarios. The given mobile unit also retains its membership to a mobility VLAN to which it had been assigned, even during roaming scenarios. Embodiments include a framework for wireless switches to advertise VLANs they support to peer wireless switches in the mobility domain, and to advertise their capability to act as VLAN servers for those VLANs. Embodiments support VLAN membership management capabilities that allow access points and peer wireless switches to request wireless switches to add VLANs to the tunnels they share.

Methods, apparatus and a computer program product provide for a Tolerant License Manager that defines a cluster of a plurality of network controllers, wherein each respective network controller contributes at least one license to a current total amount of licenses in a license pool. The Tolerant License Manager identifies at least one threatened access point upon detecting a first network controller has become unavailable. Each threatened access point comprises any access point connected to the first network controller when the first network controller becomes unavailable. The Tolerant License Manager establishes (and/or) approves a connection between a back-up controller and the threatened access point(s). While the first network controller is unavailable, the Tolerant License Manager allocates a license to each threatened access point via the back-up network controller.

A split-plane mobility network architecture separates control and data plane operations typically encapsulated in a conventional wireless controller. Configurations provide a unified split-plane mobility switch that separates the data transport and switching in a separate hardware element, and performs control plane operations via exchanges with a centralized topology, rather than simply by adjacent switches within range. In contrast to conventional switch deployment, in which the same switch handles processing demands of the control plane and the data plane, the disclosed approach separates the data plane processing base by employing a mobility agent to define adjacent switch visibility. Thus, the routing capabilities of the data plane may be enhanced, such as to handle increasingly bandwidth-hungry applications of the same user base, without uprooting the infrastructure defined by the control plane.

摘要:
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).
