A network system for a data center. In one example, a method comprises establishing, by a plurality of access nodes, a logical tunnel over a plurality of data paths across a switch fabric between a source access node and a destination access node included within the plurality of access nodes, wherein the source access node is coupled to a source network device; and spraying, by the source access node, a data flow of packets over the logical tunnel to the destination access node, wherein the source access node receives the data flow of packets from the source network device, and wherein spraying the data flow of packets includes directing each of the packets within the data flow to one of the data paths based on an amount of data previously transmitted on each of the plurality of data paths.

A method for pseudo channel hopping in a node of a wireless mesh network is provided that includes scanning each channel of a plurality of channels used for packet transmission by the node, wherein each channel is scanned for a scan dwell time associated with the channel, updating statistics for each channel based on packets received by the node during the scanning of the channel, and selecting a channel of the plurality of channels for scanning based on the statistics when the scan dwell time of a currently scanned channel ends.

Systems and methods for communication between near field communication devices within a target communication region using near field magnetic induction is disclosed. One method comprises generating a near field detectable signal at an active node having a power level sufficient to enable communication with a plurality of near field communication nodes located within the target communication region. Information is modulated onto the near field detectable signal using at least one of the near field communication nodes. The modulated information is detected at the active node. The information is then relayed on the near field detectable signal from the active node to at least one of the plurality of near field communication nodes within the target communication region.

A network system for a data center is described in which a switch fabric may provide full mesh interconnectivity such that any servers may communicate packet data to any other of the servers using any of a number of parallel data paths. Moreover, according to the techniques described herein, edge-positioned access nodes, optical permutation devices and core switches of the switch fabric may be configured and arranged in a way such that the parallel data paths provide single L2/L3 hop, full mesh interconnections between any pairwise combination of the access nodes, even in massive data centers having tens of thousands of servers. The plurality of optical permutation devices permute communications across the optical ports based on wavelength so as to provide, in some cases, full-mesh optical connectivity between edge-facing ports and core-facing ports.

In one embodiment, a device in a network receives a notification from a neighbor of the device indicative of a child node of the device requesting a parent change from the device to the neighbor. The device updates an existing routing path from the device to the child node to be routed through the neighbor, in response to receiving the notification from the neighbor. The device receives an instruction to remove the updated routing path from the device to the child node through the neighbor. The device removes the updated routing path from the device to the child node, in response to receiving the instruction to remove the updated routing path.

A client access point joins a wireless network over a wireless connection in order to allow stations access to the wireless network. To join, the client access point (having a wireless connection to a mesh network) receives a beacon frame with unique identifiers of authorized client access points from a host access point (having a wired connection to the mesh network). Responsive to a unique identifier of the beacon frame matching the unique identifier of the client access point, a connection request for a connection is sent. A connection response confirming configuration of the client access point with the host access point in accordance is received.

A first mobile device and a plurality of other mobile devices connect to a network. A routing configuration table is configured. The routing configuration table includes rules about sharing communication between the first mobile device and the plurality of other mobile devices. The first mobile device is paired with the plurality of other mobile device based on the routing configuration table. A determination is made whether the first mobile device has received a communication. In response to the determination that a communication has been received by the first mobile device, the communication is transferred to at least one mobile device of the plurality of mobile devices based on the configuration table.

Example embodiments provide apparatus, systems and methods to optimise a multicasting operation used to transmit data packets in a communication network.
