摘要： Techniques for a hub node, provisioned in a site of a hub and spoke overlay network, to receive, store, and/or forward network routing information associated with a spoke, and send packets directly to spoke(s) that are remote from the hub node. A first hub node may receive a network advertisement including a border gateway protocol (BGP) large community string from a first spoke local to the first hub node. The first hub node may send the BGP large community string to a second hub node remote from the first hub node. The second hub node may decode network routing information from the BGP large community string and store the network routing information locally. The second hub node may send a packet from a second spoke local to the second hub node directly to the first spoke without the data packet being routed via the first hub node.

摘要： Systems and methods for implementing power management features while providing a wireless asymmetric network are disclosed herein. In one embodiment, a system includes a hub having a wireless control device that is configured to control communications and power consumption in the wireless asymmetric network architecture and sensor nodes each having at least one sensor and a wireless device with a transmitter and a receiver to enable bi-directional communications with the wireless control device of the hub.

摘要： A wire-less/Wired mesh network is described, using a multi-slot modular mesh node to house diverse transceiver elements (e.g. IR, Wi-Fi, Powerline). A radio agnostic tree based mesh network is formed, based on what type of wire-less links are formed on the uplink and downlink of the backhaul and what type of radios etc are used for the Access Points AP, see FIG. 17,23.In addition to servicing IP based clients (e.g. Wi-Fi, WiMax, Bluetooth), the modular mesh nodes APs may also serve as receivers/collectors for low cost chirp devices. These devices are not “agile” and therefore contentious. APs, servicing these devices, alleviate potential contention by multiple means including: sending out a “incoming” CTS, efficient delivery through container based schedulable bus deliveries, and its reverse (moving chirp transmission times to be sequential).Multiple approaches for “pollen” to reach the intended “flower” in a timely manner are described. The method of transport is standard IP based packets yet security is inherent in this pollen-flower based system: only mesh nodes are privy to the routing tables that indicate that packet addresses are not IP. Multiple options to further obfuscate packet flow are presented.A multi-agent based approach driving business process flow is described. Such agents can also provide specialized mesh network routing e.g. navigation agents for chirp devices.Tree based routing and logical radio abstractions are revisited.An organic approach to providing category/class based form of data type identification is proposed, to efficiently match publishers and subscribers, based on the type of data being sought. A private, secure and natively Publish/Subscribe M2M community is engendered at the edge. It has loosely, dynamic and ad hoc couplings to big data servers, also operating on their own private exchange/market place, using a real time publish/subscribe infrastructure with content categories used as part of pollen identification.

摘要： The present disclosure describes an example of device for use in an Ethernet Virtualisation Interconnection (EVI) network having a Hub-Spoke structure. The EVI network comprises a first Hub Edge Device (Hub-ED) and a second Hub-ED, the device comprising a memory unit to store instructions; and a processor to perform the instructions from the memory unit. The processor receives a message having an identifier, the identifier identifying a destination address of the message. The processor selects an EVI link interface from a set of EVI link interfaces having a first EVI link interface and a second EVI link interface each associated with the identifier, wherein the first EVI link interface interfaces with the first Hub-ED and the second EVI link interface interfaces with the second Hub-ED. The processor also sends the message to one of the first Hub-ED or the second Hub-ED via the EVI link interface selected from the set of EVI link interfaces.

摘要： A method and system for providing priority to a station in a congested half duplex Ethernet network. Specifically, one embodiment of the present invention includes a method for providing priority to a peripheral component (e.g., half duplex Network Interface Card) in a congested network. The method includes the step of detecting a collision of a data packet during transmission of the data packet by a peripheral component coupled to a network. Furthermore, the method includes the step of determining a restricted back off time. It should be appreciated that the restricted back off time is substantially equal to or less than a restricted time value. Additionally, the method includes the step of causing the peripheral component to wait the restricted back off time before trying to retransmit the data packet over the network.
