A method of routing communication between nodes of a mesh network is provided. The method includes each node of the mesh network advertising a hop distance relative to a head of the mesh network, the hop distance being a measure of how many hops a node of the mesh network is from a head node of the mesh network, the head node being a node of the mesh network that controls all the other nodes of the mesh network.

To configure a wireless sensor network, a sink node receives from nodes first reports, a first report from a node indicating quality of service requirement of the node and battery information of the node, and second reports, a second report from a node indicating at least a signal strength of one signal received from another node. The information in the first reports and in the second reports are used for determining paths from the nodes to the sink node, wherein a path of a node is either a direct link from the node to the sink node or the path comprises at least one node acting as a cluster head between the node and the sink node.

A method, a system and a controller for controlling the Quality of Service, QoS, of a wireless link, providing a service from a transmitting entity to a receiving entity is suggested. Once data, decisive of the QoS of the hops of the wireless link has been received, it is determined, based on the received data, that at least one QoS target-value of one of said hops is, or is predicted, not to be met. For each of the mentioned hops, one or more actions for achieving that said at least one QoS target-value is met, is initiated and based on the determining of one or more actions, instructions, instructing at least one of the mobile relay stations how to execute one or more of said determined actions are initiated.

Aspects of the present disclosure involve systems for providing multiple egress routes from a telecommunications network for a client of the network. In general, the system provides for a client of the network to receive intended packets of information through multiple connections to the network such that load balancing and failover services for traffic to the customer are provided. The process and system allow for telecommunications network to utilize a common next-hop value of announced border gateway protocol (BGP) routes to advertise multiple routes to reach a destination customer network or address. By utilizing a common next-hop value in the announced BGP information, the devices of the network may load balance communication packets to the destination customer or address among the multiple egress locations from the network, as well as providing fast failover to alternate routes when a failure at the network or customer occurs.

An interconnect as a switch module (“ICAS” module) comprising n port groups, each port group comprising n-1 interfaces, and an interconnecting network implementing a full mesh topology where each port group comprising a plurality of interfaces each connects an interface of one of the other port groups, respectively. The ICAS module may be optically or electrically implemented. According to the embodiments, the ICAS module may be used to construct a stackable switching device and a multi-unit switching device, to replace a data center fabric switch, and to build a new, high-efficient, and cost-effective data center.

Methods and systems are provided for performing lossy dropping and ECN marking in a flow-based network. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow are acknowledged after reaching the egress point of the network, and the acknowledgement packets are sent back to the ingress point of the flow along the same data path. As a result, each switch can obtain state information of each flow and perform per-flow packet dropping and ECN marking.

A method and apparatus for configuring a communication network based on a distance metric. Information indicative of current status of communication network nodes, links between the nodes, or a combination thereof is obtained and processed to determine a network configuration. The network configuration is implementable in the communication network by adjusting one or more nodes or links. The processing includes evaluating network configurations based on a distance metric, which is indicative of lengths of shortest paths which interconnect nodes of the network. Instructions directing underlying resources to implement the network configuration can be provided. An apparatus can be a supervisory device including a network interface and a computer processor.
