摘要： Techniques are provided for seamless integration of wired and wireless functionality packet forwarding in network. A plurality of access switches are provided in each of a plurality of mobility sub-domains that are part of a mobility domain of a network. Each access switch serves one or more Internet Protocol (IP) subnets, each comprising a plurality of IP addresses. An access switch obtains an IP address for a wireless device according to the one or more IP subnets that the access switch serves. The access switch sends an association advertisement message to indicate the IP address of the wireless device and to enable other access switches and routers to compute a path to the wireless device. When a wireless device obtains an IP address, it can keep the same IP address as it roams in the mobility domain.
摘要翻译：为网络中有线和无线功能数据包转发的无缝集成提供了技术。在作为网络的移动性域的一部分的多个移动性子域中的每一个中提供多个接入交换机。每个接入交换机提供一个或多个互联网协议（IP）子网，每个网络包括多个IP地址。接入交换机根据接入交换机所服务的一个或多个IP子网获取无线设备的IP地址。接入交换机发送关联广告消息以指示无线设备的IP地址，并使其他接入交换机和路由器能够计算到无线设备的路径。当无线设备获得IP地址时，它可以保持与移动域中漫游相同的IP地址。

摘要： Techniques are provided to support roaming of wireless devices in a network such that the wireless devices can keep their Internet Protocol (IP) addresses as they roam within and across mobility sub-domains. When a wireless device roams from one access switch to another access switch, a tunneling endpoint apparatus in the wireless device's home mobility sub-domain is configured to serve as the point of presence for the roamed wireless device. Traffic for the roamed wireless device is tunneled from the access switch where the wireless device has roamed (where it is currently attached) to the tunneling endpoint apparatus. When the wireless device roams across mobility sub-domains, then traffic is tunneled from the access switch where the wireless device is currently attached to the tunneling endpoint apparatus in that mobility sub-domain (called a “foreign” mobility sub-domain) to the tunneling endpoint apparatus in the wireless device's home mobility sub-domain.
摘要翻译：提供技术以支持网络中的无线设备的漫游，使得无线设备可以在移动性子域内漫游时保持其互联网协议（IP）地址。当无线设备从一个接入交换机漫游到另一个接入交换机时，无线设备的归属移动性子域中的隧道端点设备被配置为用作漫游无线设备的存在点。漫游无线设备的业务从无线设备已经漫游（其当前附接的）的接入交换机隧道传送到隧道终端设备。当无线设备漫游跨越移动性子域时，则将业务从无线设备当前附接到的接入交换机隧道传送到该移动性子域（称为“外部”移动性子域）的隧道端点设备，隧道终端设备在无线设备的归属移动性子域中。

摘要： A system and method for a hierarchical distributed control architecture to support roaming wireless client devices. Access switches serve one or more Internet Protocol (IP) subnets that include plural IP addresses. The access switches are arranged in switch peer groups and store information about other access switches in that switch peer group and about locations of wireless client devices that are associated with any access switch in the switch peer group. The access switches are further grouped into a corresponding mobility sub-domain each including plural switch peer groups. Plural controller devices control access switches in a corresponding mobility sub-domain. Each controller device stores information about the access switches and about locations of wireless client devices within its mobility sub-domain. A central controller device communicates with the controller devices for the respective mobility sub-domains. The central controller device stores information about locations of wireless client devices in the mobility sub-domains.

摘要： Techniques are provided herein to support roaming of wireless mobile client devices from one wireless local area network access point device to another wireless local area network access point device. Neighbor discovery messages are received from wireless mobile client devices. A neighbor discovery message specifies a target address for a neighbor discovery function. A response to a neighbor discovery message is sent to a wireless mobile client device such that the response message appears to have been sent by a wireless mobile client device that has an address that corresponds to the target address of the neighbor discovery message.

摘要： A method and apparatus for transferring articles from a transportable container, for example, a SMIF pod, to a second container, for example, a processing station having a port which provides access to the interior region of the processing station. A non-contact seal or an isolation cover or skirt seals the port so that the interior region of the container can be purged of contaminants prior to exposing the interior environment of the processing station to the environment within the container. The purging of the container may be a multi-step process in which the container door is moved between several intermediate positions so that the container door itself is purged prior to the purging of the environment within the container.

摘要： Techniques are provided to enable support of roaming wireless devices in a network such that the wireless devices can keep their Internet Protocol (IP) addresses as they roam across mobility sub-domains. Traffic for a wireless device that roams is tunneled back to the access switch that serves the IP subnet which includes an IP address for the wireless device. Traffic is tunneled back to that access switch for the wireless device when the wireless device roams to another access switch which does not serve the IP subnet for the wireless device in the same mobility sub-domain and when the wireless device roams to a different mobility sub-domain, in which case the traffic is tunneled between tunneling endpoints in the respective mobility sub-domains.

摘要： Techniques are provided to manage how router advertisement messages are forwarded for ultimate wireless transmission in a wireless network. In one embodiment, a multicast router advertisement message intended for a virtual local area network is converted into individual unicast router advertisement messages directed to specific wireless mobile client devices that are part of that virtual local area network. In another embodiment, router advertisement messages are routed between controllers according to the current location of a wireless mobile client device. In still other embodiments, techniques are provided to minimize the volume of the router advertisement messages sent over a wireless network, and to proactively send a unicast router advertisement message to a mobile client device that has performed a handoff, without waiting for a router solicitation message.
