摘要： In one embodiment, a method includes, in each of a plurality of mesh access points, connecting to one of a plurality of mesh controllers in a mesh network and passing connection information to the one mesh controller. The mesh access points include a wired mesh access point having a wired connection to the one mesh controller, and wireless mesh access points having a wireless connection to the one mesh controller via the wired mesh access point. The method also includes generating, in each mesh controller, a corresponding link state table based on the passed connection information from each corresponding connected mesh access point. The method also includes generating in at least one of the mesh controllers a mesh table, identifying all of the connecting links for the mesh access points connected among the mesh controllers, based on the mesh controllers sharing the respective link state tables.

摘要： In one embodiment, a sensor device in a network detects an alarm condition. The sensor device generates an alarm message based on the detected alarm condition and waits for a delay whose length is inversely proportional to a distance between the sensor device and a downstream destination device for which the alarm message is destined. During the delay, the sensor device receives one or more additional alarm messages from one or more upstream sensor devices. The sensor device coalesces the one or more received alarm messages from the one or more upstream sensor devices with the alarm message generated at the sensor device, to form a coalesced alarm message, and transmits the coalesced alarm message downstream towards the downstream destination device, after expiration of the delay.

摘要： Each mobile router in an ad hoc mobile network is configured for concurrently attaching to multiple parents advertising respective parent depths relative to a clusterhead of the ad hoc mobile network. The mobile router selects an advertised depth relative to the clusterhead based on adding a prescribed increment to a maximum one of the parent depths, enabling the mobile routers to form a directed acyclic graph relative to the clusterhead. Each mobile router sends to each of its parents a neighbor advertisement message specifying at least one reachable prefix, a corresponding cost for reaching the reachable prefix, and a corresponding sequence identifier that enables the parents to validate the neighbor advertisement message relative to stored router entries. Hence, mobile routers automatically can form a directed acylic graph relative to the clusterhead, and can distribute routing information with minimal overhead.

摘要： In one embodiment, one or more routing trees may be determined based on corresponding root nodes to reach a particular receiving node in a computer network. A delay value may be calculated at each node of the routing tree, the delay value inversely proportional to a distance between each respective node and the root node of the tree. Upon detecting a trigger at a particular node of the tree to transmit a stormed message to the particular receiving node (e.g., an alarm), the particular node may initiate a timer to count down the delay value in order to receive any upstream node stormed messages prior to expiration of the timer. The particular node may then coalesce the upstream node stormed messages with the stormed message of the particular node, and may transmit the coalesced stormed message downstream along the tree toward the particular receiving node upon expiration of the timer.

摘要： In one embodiment, a node in a computer network may receive data of a particular type at a first frequency (e.g., a sensor in a sensor network), and may correspondingly determine whether there is at least one interested subscriber for the data of the particular type, where the interested subscriber desires the data at a second frequency. If there is an interested subscriber, buffered data publishing may be dynamically activated at the node in response to a ratio between the second and first frequencies being less than a configured threshold. In particular, buffered data publishing comprises buffering the received data and transmitting a latest received data to the interested subscriber at the second frequency.

摘要： In one embodiment, a method includes a mesh point receiving mesh advertisement messages from advertising mesh points of a wireless mesh network having a mesh portal with a wired connection to a wired network. Each mesh advertisement message specifies a corresponding metric for reaching the mesh portal and has a corresponding signal strength indicator. An ordered group of parent access points, ordered based on the respective metrics, is generated from among the advertising mesh points, starting with a first parent access point having a corresponding optimum metric for reaching the mesh portal and independent of the corresponding signal strength indicator. A registration message is sent to each of the parent access points identifying a corresponding specified priority based on a corresponding position in the ordered group, for use by the corresponding parent access point in selecting a minimum interframe spacing for forwarding a wireless packet received from the mesh point.

摘要： Gateways providing connectivity for respective private IPv4 networks to an IPv6 network establish communications between IPv4 nodes in the private network. Network address translation-protocol translation (NAT-PT) state entries are created by gateway pairs enabling translation of IPv4 packets between first and second IPv4 nodes in respective first and second IPv4 private networks into IPv6 packets for transmission via the IPv6 network. Each NAT-PT state entry specifies the IPv6 addresses for the first and second IPv4 nodes, and the IPv4 addresses used to identify the first and second IPv4 nodes in the corresponding private IPv4 network. Each gateway is configured for generating the IPv6 address for each local IPv4 node based on prepending its corresponding assigned private IPv4 address with a corresponding prescribed IPv6 prefix assigned to the gateway. Hence, gateways can dynamically establish communications between private networks without tunneling protocols, enabling deployment of latency-sensitive applications such as Voice over IP.
