20120166515 | Providing and Resolving an IP Address for Swarm-Based Services - Providing and maintaining an IP address for swarm-based services. A swarm is a group of digital devices operating cooperatively on a network, such as a group of wireless access points. Services may be distributed over members of the swarm, with each service having a master which is hosted on one member of the swarm. The master broadcasts a periodic heartbeat, advertising its service and the address of the host member. If a swarm member fails to hear a particular service's heartbeat for a predetermined interval, it broadcasts a message announcing its intent to be master for the service. If the swarm member does not receive any other broadcasts from members indenting to take the role of master for the service, it takes over the role of master for the service and begins broadcasting periodic heartbeats identifying itself as the service master. If multiple swam members broadcast their intent to become master of the same service, a resolution protocol is invoked and one swarm member is selected to be master. In operation, each member of the swarm maintains a table of services and the address of the swarm member hosting the service; this information is obtained from the periodic heartbeats broadcast by each service master. When a swarm member receives a service request, the request is either redirected to the service master, or the request is terminated at the swarm member and handled. | 06-28-2012 |
20120166519 | Provisioning a Swarm - Provisioning access points operating in a swarm. A swarm is a plurality of digital devices, such as access points, connected using a digital network and operating in a cooperative manner. When an access point (AP) is first powered up, it lacks provisioning information such as channel numbers, power levels, SSIDS, security settings, and so on. The process of supplying this information required to get the AP operating as part of a network is called provisioning. An unprovisioned AP in a swarm first attempts to obtain a DHCP address. Once it gets a DHCP address or selects an address such as from the link-address (169.254.xx.xx) group, it advertises a predetermined wireless SSID which is only used for provisioning the swarm.

20120243456 | Bridge Mode Firewall Mobility - Mobility of firewall rules for clients moving among bridge AP nodes in a wireless network. APs operate in bridge mode. A wireless client C is associated with a first AP. As part of that association, the first AP establishes and maintains personal firewall rules and state for client C. When wireless client C associates with a second AP in the L2 domain, the second AP sends session request to other APs. This may be in the form of a multicast message. Optionally, the second AP may send a unicast message to the first AP indicating that client C has associated with the second AP. APs receiving the multicast session request message for client C check their tables to see if they have stored firewall or other state for client C. APs having storied firewall or other state for client C send session response messages to the second AP containing stored firewall sessions and other state for client C. When the second AP receives a session response, it sends an acknowledgement to the AP which sent the response. When the AP, such as the first AP, receives the acknowledgement, it may remove all stored state for client C. If the second AP receives session response messages for client C from multiple APs, it acknowledges each, and creates session entries and state using the oldest rules in the session response messages. Flags may be logically ORed together. | 09-27-2012 |
20130003654 | Mesh Node Role Discovery and Automatic Recovery - Embodiments of the present disclosure provide for configuring and managing mesh nodes during occasional failure of mesh nodes or addition of new mesh nodes. The disclosed system first determines whether a mesh node is a mesh portal or a mesh point. If it is a mesh portal, the mesh node will advertise its capacity as a mesh portal to other mesh nodes in the network. If it is a mesh point, the mesh node attempts to automatically recover connection to the wireless mesh network if it identifies a unique wireless network based on its associated network identifier. If more than one network identifiers are discovered, the mesh node delays establishing connection to the wireless mesh network until a selection is received. | 01-03-2013 |
20130201978 | Method and System for Partitioning Wireless Local Area Network - The present disclosure discloses a method and system for partitioning WLAN in order to separate network traffic from different WLANs. Specifically, a network device receives a packet from a client connected to a first network device on an access network. The network device then determines that the received packet is associated with a VLAN that is pre-configured on the first network device based on the access network to which the client is connected. Furthermore, the network device transmits the packet to a MAC layer switching device, which is not configured with the VLAN that is pre-configured on the network device. The packet includes one of a DHCP discovery message, an ARP request message, a unicast message, a multicast message, and a broadcast message. The unicast message will be transmitted to the second network device on the pre-configured VLAN prior to being transmitted to another network device outside the pre-configured VLAN. | 08-08-2013 |
20130268660 | Providing and Resolving an IP Address for Swarm-Based Services - According to one embodiment of the disclosure, a non-transitory computer readable medium (CRM) comprising instructions, which when executed by one or more hardware processors, causes performance of operations comprising: listening, by a first digital device in a group of digital devices, for any advertisement for a particular service; responsive to the first digital device not receiving any advertisement for the particular service for a predetermined period of time: transmitting, by the first digital device, a first advertisement for the particular service; and providing, by the first digital device, the particular service. | 10-10-2013 |
20150038188 | Task Processing and Resource Sharing in a Distributed Wireless System - The present disclosure discloses a system and method for task processing and resource sharing in a distributed wireless system. The system includes a processor and a memory storing instructions that, when executed, cause the system to: identify a plurality of nodes in a distributed wireless system, each node of the plurality of nodes associated with a radio frequency neighborhood, the radio frequency neighborhood of one node including one or more other nodes that hear beacons from the one node; assign a task to the plurality of nodes; split the task into a plurality of subtasks; assign the plurality of subtasks to the plurality of nodes; receive a plurality of subtask processing results from the plurality of nodes; and combine the plurality of subtask processing results to generate a task processing result for the task. | 02-05-2015 |
20150117420 | Communicating with a Distribution System via an Uplink Access Point - The present disclosure discloses a system and method for communicating with a distribution system via an uplink access point. The system includes a processor and a memory storing instructions that, when executed, cause the system to: receive, at a first network device, an original packet from a client device; identify a source MAC address of the original packet as a MAC address of the client device; identify an IP address of the original packet as an IP address of the client device; generate a modified packet from the original packet by changing the source MAC address from the MAC address of the client device to a MAC address of the first network device; preserve the IP address in the modified packet to be the IP address of the client device; and forward the modified packet from the first network device to a second network device. | 04-30-2015 |
