摘要： 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.

摘要： Unified mobility switches often define a virtual LAN (VLAN), including a combination of mobility tunnels and access tunnels, via which packets are transported to a mobile device over a combination of physical connections and wireless links. A unified switch may have multiple ports available to route a packet to a particular destination, since the unified switches identify routing paths for both physical connections and VLANs. A particular unified switch may therefore have multiple routes to a common destination, which can lead to a routing loop across a network of switches supporting both physical and virtual connections. A unified mobility switch provides loop detection and prevention through a set of rules for qualifying connections as virtual tunnels or physical connections, and defining a single path where multiple potential paths exist.

摘要： 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.

摘要： A mobility network architecture includes a control plane and data plane. The control plane supports notification of VLAN configurations. The data plane supports routing of data amongst VLANs. Each VLAN has an associated identifier value as well as a version number. The version number for a respective VLAN can be updated to a new value each time there is a change to the VLAN. Typically, a controller communicates over the control plane to notify each member switch when a version number has changed for a VLAN. If controller notification fails, a member switch can receive a notification from a neighboring switch that the version number for a VLAN has been modified. In response to detecting such a condition, the switch receiving the notification can prevent forwarding of data even though the switch does not receive notification from the controller that the version number for the VLAN has changed.

摘要翻译：移动网络架构包括控制平面和数据平面。控制面板支持VLAN配置通知。数据平面支持VLAN之间的数据路由。每个VLAN都有相关的标识符值以及版本号。每当VLAN更改时，相应VLAN的版本号可以更新为新值。通常，当VLAN的版本号更改时，控制器通过控制平面进行通信，以通知每个成员交换机。如果控制器通知失败，成员交换机可以从相邻的交换机接收到VLAN的版本号被修改的通知。响应于检测到这种情况，接收通知的交换机即使交换机没有从控制器接收到VLAN的版本号已经改变的通知，也可以防止数据的转发。

摘要： A method, system and computer readable medium for fast failover of an access point are described. A system can cause a failover of a first wireless access point when a wireless control point determines that a first wireless switching plane has failed through a platform link failure mechanism. The system can also prevent a failover of the first wireless access point or a second wireless access point when a message is received from both the first wireless switching plane and a second wireless switching plane indicating that the other wireless switching plane has failed.
