| 20080235783 | P-GANC OFFLOAD OF URR DISCOVERY MESSAGES TO A SECURITY GATEWAY - In one embodiment, a security gateway receives an IPSec Initiation (IPSec INIT) request from a client.

| 20100113039 | WIRELESS MACRO CELL OVERLAY - Overlaying a Wireless Macro Cell architecture on a Micro Cell network. WLAN MAC Address Translation (WMAT) is used to translate BSSIDs from the BSSID used to initialize a radio in an access node and identify communications between the radio in the access node and a controller, and the BSSID used over the air for Macro Cell operation. WMAT is used for transmit operations, translating the BSSID of outgoing packets to the Macro Cell BSSID prior to wireless transmission. On the receive side, packets undergo WMAT and transmission to the controller if the STN MAC address of the sender is in an ACK table associated with the radio, or the packet is one of a predetermined type. The ACK table is managed by transmit operations, and by control commands from the controller. | 05-06-2010 |
| 20100275017 | Peer-to-Peer Forwarding for Packet-Switched Traffic - Establishing peer-to-peer tunnels between clients in a mobility domain. In normal operation, clients attached to a network having access nodes connected to a central controller transfer all traffic through the central controller. This traffic is passed using tunnels between the access node and the central controller. Tunnels may be encrypted, and GRE tunnels may be used. A mobility manager operating in the controller tracks access nodes connected to the controller, and clients connected to those access nodes. When the mobility controller recognizes traffic passing between clients in its mobility domain that is eligible for peer-to-peer forwarding, it instructs the access nodes supporting the clients to establish a peer-to-peer tunnel between the nodes, and direct the client traffic through this peer-to-peer tunnel. The peer-to-peer tunnel may be session based, or may be aged. Eligibility of traffic for peer-to-peer tunnels may be controlled by rules, such as limiting peer-to-peer tunnels by source or destination, by port or protocol, and the like. | 10-28-2010 |
| 20100281180 | Initiating Peer-to-Peer Tunnels - Initiating peer-to-peer tunnels between clients in a mobility domain. Client traffic in a mobility domain normally passes from the initiating client to an access node, and from the access node through a tunnel to a controller, and then through another tunnel from the controller to the destination access node, and the destination client. When initiated by the controller, the access nodes establish a peer-to-peer tunnel for suitable client traffic, bypassing the “slow” tunnels through the controller with a “fast” peer-to-peer tunnel. Traffic through this “fast” tunnel may be initiated once the tunnel is established, or traffic for the “fast” tunnel may be queued up until traffic has completed passing through the “slow” tunnel. This queue and release process may be bidirectional or unidirectional depending on the traffic. Completion of slow tunnel traffic may be sensed in a number of ways. Slow tunnel traffic may be timed out, and queued traffic released after a preset time since the last packet was sent through the slow tunnel. The identity of the last packet sent through the slow tunnel may be retained, and queued traffic released when an acknowledgement for that packet is received. A special packet may be sent through the slow tunnel and queued traffic released when an acknowledgement for that packet is received. | 11-04-2010 |

| 20110258236 | Secure Hotspot Roaming - Secure hotspot roaming in wireless networks. An enterprise works with one or more hotspot providers to provide secure access to its clients through hotspot locations. The enterprise provides the hotspot provider, or service provider (SP), with the addresses of enterprise controllers used for client authentication. The SP maintains a database for its controllers which maps the enterprise realm to the address of the enterprise controller. When a client connects to a hotspot access point (AP), the hotspot AP sends client information such as MAC address to a SP controller. The SP controller determines if this is a new or a known client by looking up the client information in a local client to realm database. If the client is known and the realm associated with the client has an entry in the realm to enterprise controller database, the hotspot AP is instructed to begin client authentication with the specified enterprise controller. If the client is not known, authentication begins with the SP controller, and the client is queried for realm information. An entry is made in the SP controller's client to realm database for the client. If a corresponding record is present in the realm to enterprise database, the SP controller instructs the hotspot AP to dynamically switch authentication from the SP controller to the enterprise controller. The realm to enterprise database may also be placed on the hotspot AP, so that the hotspot AP may determine if the client should be passed to an enterprise controller and begin authentication with the enterprise controller directly. | 10-20-2011 |
