APPARATUS, SYSTEM AND METHOD OF ESTABLISHING A MESH DATA PATH BETWEEN NEIGHBOR AWARENESS NETWORKING (NAN) DEVICES
Some demonstrative embodiments include apparatuses, systems and/or methods of establishing a mesh data path. For example, a first Neighbor Awareness Networking (NAN) device may be configured to transmit a NAN data path request to a second NAN device to request to establish a NAN data path between the first NAN device and the second NAN device, the NAN data path request including a first path information attribute corresponding to a mesh data path; and to process a NAN data path response from the second NAN device, the NAN data path response including a second path information attribute corresponding to the mesh data path, the second path information attribute including a path status indicator to indicate whether mesh data path routing to the destination address of the mesh data path is successful.
NODE CONFIGURATION AND SELF-HEALING FOR AD HOC NETWORKS
A network includes at least one node to communicate with at least one other node via a wireless network protocol. The node includes a network configuration module to periodically switch a current node function of the node between an intermediate node function and a leaf node function. The switch of the current node function enables automatic reconfiguration of the wireless network based on detected communications between the at least one node and at least one intermediate node or at least one leaf node via the wireless network protocol.
ROUTING SYSTEM WITH LEARNING FUNCTIONS AND ROUTING METHOD THEREOF
The present disclosure illustrates a routing system with learning functions and a routing method thereof. By detecting a raw packet's packet header and an entry port receiving the raw packet, a routing message is queried from a path table by the packet header and the entry port. When there is not the routing message, the raw packet is routed by a kernel and the routing result is recorded in the path table to be the routing message. When there is the routing message, the packet header of the raw packet is replaced with a modified packet header recorded in the routing message, to form a modified packet, and the modified packet is transmitted from the transmission port recorded in the routing message, to achieve the technical effect of improving the routing performance for the packets with the same packet headers and the same entry ports.
NETWORK FLOW MANAGEMENT SYSTEM
A network flow management system includes controllers that are each coupled to a subset of switch devices, and a flow management server system that is coupled to each of the controllers. The flow management server system collects first-level flow information for the switch devices from the controllers, and filters and structures the first-level flow information to generate second-level flow information. The flow management server system then analyzes the second-level flow information based on current flow operation policies that are configured to cause the switch devices to perform first flow operations and, in response, determines flow operation policy changes. The flow management server system then distributes updated flow operation policies that includes the flow operation policy changes to each of the controllers, where the updated flow operation policies cause the switch devices to perform second flow operation that are different than the first flow operations.
COMMUNICATING ROUTING MESSAGES USING SERVICE DISCOVERY IN NEIGHBOR AWARENESS NETWORKS
This disclosure describes methods, devices, and systems related to communicating routing messages using service discovery in neighbor awareness networks (NAN) and further building a routing table for a mesh network. A device may assign a NAN service name to a routing protocol. The device may determine a NAN service discovery frame comprising a routing protocol message of the routing protocol. The device may cause to send the NAN service discovery frame to a second device during a discovery window.
APPARATUS AND METHOD TO PERFORM ALL-TO-ALL COMMUNICATION WITHOUT PATH CONFLICT IN A NETWORK INCLUDING PLURAL TOPOLOGICAL STRUCTURES
An apparatus stores connection information indicating connection relationship among topological structures in a network, in which first-type topological structures are coupled to second-type topological structures. The apparatus stores first transfer-patterns each indicating a combination of input and output ports for performing all-to-all communication without path conflict in each of the first-type topological structures, and second transfer-patterns each indicating a combination of input and output ports for performing all-to-all communication without path conflict in each of the second-type topological structures. The apparatus identifies paths from transmission sources to transmission destinations for a combination of the first and second transfer-patterns, and determines, based on the identified paths, a transfer-pattern with which to perform all-to-all communication without path conflict from the transmission sources to the transmission destinations, and determines output ports in each of the first- and second-type topological structures, corresponding to the identified paths.
Communication device, control method therefor, and program
Even when a plurality of communication parameter providing devices exist, a communication parameter setting process is enabled. When a plurality of communication parameter providing devices exist, one of the communication parameter providing devices is determined. For example, all the communication parameter providing devices are caused to stop the providing process. Alternatively, a user is allowed to select a communication parameter providing device. Alternatively, a communication parameter providing device is determined in accordance with a predetermined rule.
Mobile node host route installation and withdrawal
In general, techniques are described for atomically installing and withdrawing host routes along paths connecting network routers to attenuate packet loss for mobile nodes migrating among wireless LAN access networks and a mobile network. In some examples, whenever the mobile node moves from one attachment point to the next, it triggers the distribution of its host route from the new attachment point toward the service provider network hub provider edge (PE) router that anchors the mobile node on a service provider network. Routers participating in the Mobile VPN install the host route “atomically” from the attachment point to the mobile gateway so as to ensure convergence of the network forwarding plane with the host route toward the new attachment point prior to transitioning mobile node connectivity from a previous attachment point.
Communication system, control apparatus, forwarding node, control method and program
A plurality of forwarding nodes includes: a topology holding unit that holds as first topology information connection relationship between an own node and at least part of the group of nodes; a topology notification unit that notifies a node(s) adjacent to the own node among the group of nodes of the first topology information; and an in-band communication unit that notifies a control apparatus of the first topology information. The control apparatus includes: a topology configuration unit that generates second topology information by combining a plurality of pieces of the first topology information notified by the plurality of forwarding nodes; and an in-band control unit that derives a path from the control apparatus to the plurality of forwarding nodes based on the second topology information and establishes a control channel for controlling the plurality of forwarding nodes along the derived path.
Method, device, system for detecting data link, controller and gateway
Disclosed are a method, device, system for detecting a data link, controller, and gateway. The method comprises: an SDN controller sends a GTP request message to a first UGW, and instructs the first UGW to send the GTP request message to another GTP endpoint in a GTP user plane signaling format; the SDN controller receives a GTP response message from the first UGW, and detects a data link between the first UGW and the another GTP endpoint according to the GTP response message, the GTP response message being corresponding to the GTP request message. The disclosure solves the problem in the prior art that logic of a user plane and logic of a control plane are unclear during detection of a data link between GTP endpoints, thereby improving the clarity of the logic of the user plane and the clarity of the logic of the control plane.
