A communications method includes determining, by a first platoon member, at least one second platoon member, where the first platoon member and the at least one second platoon member belong to a same platoon, and signal quality of a communication link from the first platoon member to each second platoon member is less than a first preset quality threshold, determining, by the first platoon member, a target communications node, where signal quality of a communication link from the target communications node to each second platoon member is greater than or equal to the first preset quality threshold, and sending, by the first platoon member, to-be-sent data to each second platoon member through the target communications node.

Some embodiments provide a method of transmitting data in a logical network with multiple branches and a hub cluster with multiple hubs of a first category of hubs and multiple hubs of a second category of hubs. The method, for each of the multiple branches (1) assigns a first hub of the first category of hubs to the branch (2) assigns a second hub of the second category of hubs to the branch, and (3) provides a set of application based policies to the branch. The application based policies direct the branch to route different types of network traffic of the application through the first hub than through the second hub. Each hub of the first category of hubs, in some embodiments, includes a set of resources equivalent to a set of resources of each other hub of the first category of hubs.

A method including receiving, by a device in communication with a first endpoint and a second endpoint in a mesh network, a first communication from the first endpoint and a second communication from the second endpoint; selectively comparing, by the device, first observed connection state information associated with the first communication with the stored connection state information associated with outgoing communications transmitted by the device, and second observed connection state information associated with the second communication with the stored connection state information; and selectively processing, by the device, the first communication based at least in part on a result of selectively comparing the first observed connection state information with the stored connection state information, and the second communication based at least in part on a result of selectively comparing the second observed connection state information with the stored connection state information. Various other aspects are contemplated.

Systems and methods for controlling congestion of a data network are provided. An engine round-trip time (RTT) and a fabric RTT for a network flow are determined. An engine-based congestion window size for the flow is determined based on the engine RTT and a target engine RTT. A fabric-based congestion window size for the flow is determined based on the fabric RTT and a target fabric RTT. The smaller of the engine-based congestion window size and the fabric-based window size is selected for use in transmitting a future packet associated with the flow. The target engine RTT is determined based in part on the current congestion window used to transmit packets for the flow and/or the target fabric RTT is determined based on a number of hops packets associated with the flow traverse from a source to a destination associated with the flow.

A method including receiving, by a first device in communication with a second device in a mesh network, an incoming packet from the second device; determining, by the first device, that the incoming packet is an initiation packet requesting information or a response from the first device or a response packet providing a response to an outgoing packet transmitted by the first device; and processing, by the first device, the incoming packet based at least in part on determining that the incoming packet is the initiation packet or the response packet. Various other aspects are contemplated.

Provided is a technique for load balancing in a mesh network. The technique includes receiving a signal from a first gateway device of the mesh network and determining, responsive to the signal, whether a condition for connecting to the gateway device is satisfied. The method also includes initiating a first connection with the first gateway device when the condition is satisfied. A second connection is initiated between the node and a second gateway device (i) when the condition is not satisfied and (ii) when the first gateway device is at full capacity.

A first device in a communication network receives from at least one second device in the communication network, a first request for acquiring a token, the token being permission for communicating with a third device. Based on the first request, a device from the at least one second device and the first device as a communication device is selected for providing a communication service to the third device in the communication network; and the token is transmitted to the communication device. The communication device receives the token for communicating with the third device. Other devices receive key information associated with communication of the third device from the first device, and monitor data associated with the communication of the third device.

The present invention relates to a receiver-centric transmission system for IoT systems, such as lighting networks, with combo protocol radio chips that share a single radio front-end for two or more transmission protocols of different network technologies while preventing unacceptable performance degradations in one or both protocol modes. The receiver-centric approach allows implementation of two networks with acceptable performances on one single radio chip per node rather than requiring two radio chips per node.

An information handling system operating a mesh network link aggregation optimization system may comprise a plurality of mesh access points, and one or more client devices connected via a plurality of wireless links forming a mesh wireless network. A processor may execute code instructions to generate a congestion score for each of the links based on measured traffic and quality of service of each of the links, determine the congestion score for a congested link does not meet a preset congestion threshold value, determine a location within the mesh wireless network in which to aggregate links between two mesh access points, based on availability of one or more radios, and transmit an instruction to one of the plurality of mesh access points to aggregate two or more links at the network layer at the determined location for simultaneous transmission on a single band.

In order to provide a reliable interconnection between a wireless mesh network and an external network, more than one border router device may be deployed. A novel load balancing method, and the related system and devices, are disclosed in this invention. By embedding actual traffic load information in the frequency of sending the border router advertisements, automatic traffic load balancing among multiple border routers is realized in 5 the system, without extra signaling overhead or any change to the beacon packet structure.
