20110274035 | Routing to the Access Layer to Support Mobility of Internet Protocol Devices - 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. | 11-10-2011 |
20110274036 | Maintaining Point of Presence at Tunneling Endpoint for Roaming Clients in Distributed Wireless Controller System - 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. | 11-10-2011 |
20110274037 | Hierarchical Control Signaling for Mobile Clients in Distributed Wireless Controller System - A system and method are provided for a hierarchical distributed control architecture to support roaming of wireless client devices. A plurality of access switches are provided and configured to serve one or more Internet Protocol (IP) subnets that comprises a plurality of IP addresses. The plurality of access switches are arranged in switch peer groups such that each access switch within a given switch peer group is configured to store information about other access switches in that switch peer group and about locations of wireless client devices that are associated with any wireless access point on any access switch in the switch peer group. The plurality of access switches are further grouped into a corresponding one of a plurality of mobility sub-domains each comprising a plurality of switch peer groups. A plurality of controller devices are provided, each configured to control access switches in a corresponding mobility sub-domain. Each controller device stores information about the plurality of access switches within its mobility sub-domain and about locations of wireless client devices at access switches in its mobility sub-domain. A central controller device is provided and configured to communicate with the plurality of controller devices for the respective mobility sub-domains. The central controller device is configured to store information about locations of wireless client devices in the mobility sub-domains. | 11-10-2011 |
20110274082 | Maintaining Point of Presence at Access Switch for Roaming Clients in Distributed Wireless Controller System - 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. | 11-10-2011 |
20110280213 | Guest Access Support for Wired and Wireless Clients in Distributed Wireless Controller System - Techniques are provided to enable a support for guest access of devices in a network. At a controller apparatus in a first mobility sub-domain of a network comprising a plurality of mobility sub-domains, a request message containing a request for guest network access for a device is received from a first access switch in the first mobility sub-domain. The controller apparatus forwards the request message to a guest controller. At a tunneling endpoint apparatus in the first mobility sub-domain, a tunnel is established to the guest controller to carry traffic between the device and the guest controller. Traffic for the device passes in a tunnel between the first access switch and the tunneling endpoint apparatus in the first mobility sub-domain, through the tunneling endpoint apparatus in the first mobility sub-domain and in the tunnel between the routing apparatus in the first mobility sub-domain and the guest controller. | 11-17-2011 |
