    Abstract: 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.

    Abstract translation: 统一移动交换机通常定义虚拟LAN（VLAN），包括移动隧道和接入隧道的组合，通过物理连接和无线链路的组合，将数据包传输到移动设备。 统一交换机可能有多个端口可用于将数据包路由到特定的目的地，因为统一交换机可以识别物理连接和VLAN两者的路由路径。 因此，特定的统一交换机可以具有到公共目的地的多条路由，这可以导致跨越支持物理和虚拟连接的交换机的网络的路由环路。 统一的移动交换机通过一组用于将连接限定为虚拟隧道或物理连接的规则，并且定义存在多个潜在路径的单个路径来提供循环检测和预防。

    Abstract: A method, apparatus and computer program product for performing location based load balancing of wireless access points and wireless switches is presented. A wireless controller (WC) receives an associate message from an Access Point (AP)/wireless switch (WS) at the WC. The WC then determines whether a preferred WC for the AP/WS is available. When the preferred WC is not available, then the WC determines if an alternate WC for the AP is available. When the alternate WC is not available, an administrator configured policy may be used that maps the AP to a specific WC. When the policy does exist then the AP is coupled to the WC according to the policy and when the policy does not exist then the WC parses the AP/WS location information for the AP/WS to determine an available geographically closest WC for the AP/WS and sends a message to the AP/WS relating to the available WC. The WC will also assign an available geographically closest WS to AP.

    Abstract translation: 提出了一种用于执行无线接入点和无线交换机的基于位置的负载平衡的方法，装置和计算机程序产品。 无线控制器（WC）在WC处从接入点（AP）/无线交换机（WS）接收关联消息。 然后，WC确定AP / WS的首选WC是否可用。 当首选WC不可用时，WC确定AP的替代WC是否可用。 当备用WC不可用时，可以使用将AP映射到特定WC的管理员配置的策略。 当策略确实存在时，AP根据策略耦合到WC，并且当策略不存在时，WC解析AP / WS的AP / WS位置信息，以确定AP / WS的可用的地理位置最接近的WC， WS并向与可用WC相关的AP / WS发送消息。 WC还将为AP分配一个可用的地理位置最接近的WS。

    Abstract: 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.
