摘要： A method, apparatus and computer program product for providing seamless Internet Protocol multicast connectivity in unified networks is presented. The systems disclosed herein are able to transfer, from a designated (i.e., first) VLAN to a roaming (i.e., second) VLAN, a multicast stream from a multicast server in a mobility VLAN that is not available at the roaming VLAN. In operation, example embodiments of the present invention receive a report identifying a roaming mobile unit as a member of a first VLAN and forward the report to a first mobility switch in the first VLAN. The multicast stream is then received and forwarded toward the roaming mobile unit in the second VLAN so that transfer of the multicast stream from the first VLAN to the second VLAN is seamless.

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).

摘要： 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.

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.

摘要： 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.
摘要翻译：分离平面移动网络架构分离了通常封装在常规无线控制器中的控制和数据平面操作。配置提供了一个统一的分裂平面移动交换机，它将数据传输和交换分开在一个单独的硬件元素中，并通过与集中式拓扑的交换执行控制平面操作，而不是简单地通过范围内的相邻交换机执行控制平面操作。与传统的交换机部署相反，其中相同的交换机处理控制平面和数据平面的处理需求，所公开的方法通过使用移动性代理来分隔数据平面处理基站以限定相邻的交换机可见性。因此，可以增强数据平面的路由能力，例如处理相同用户群的越来越多的带宽需求的应用，而不用根除由控制平面定义的基础设施。

摘要： A method for receiving an optical signal is included where an ingress signal is split into a first portion and a second portion. A relative delay is induced between the first portion and the second portion, which are optically interfered to generate at least one interfered signal. Quality criteria of a monitored signal at least based on the at least one interfered signal is monitored so that a relative delay based in the quality criteria may be adjusted.

摘要： A method, apparatus and computer program product for providing Virtual Local Area Network (VLAN) server redundancy is presented. A mobility switch (MS) advertises to at least one peer mobility switch, VLANs configured as server capable, the advertising including providing priority information relating to a server for the VLAN. The MS receives advertising from the at least one peer mobility switch and elects a server for a mobility VLAN which is not mapped locally. The MS maintains a current server and a list of alternative servers for the VLAN and determines when the MS looses connection with the current server for the VLAN and moves the VLAN to an alternate server contained on the list.
