摘要： In one embodiment, a management device in a computer network determines when nodes of the computer network join any one of a plurality of field area routers (FARs), which requires a shared-media mesh security key for that joined FAR. The management device also maintains a database that indicates to which FAR each node in the computer network is currently joined, and to which FARs, if any, each node had previously joined, where the nodes are configured to maintain the mesh security key for one or more previously joined FARs in order to return to those previously joined FARs with the maintained mesh security key. Accordingly, in response to an updated mesh security key for a particular FAR of the plurality of FARs, the management node initiates distribution of the updated mesh security key to nodes having previously joined that particular FAR that are not currently joined to that particular FAR.

摘要： In one embodiment, a network of nodes is configured to communicate according to a configuration of Available Routing Construct (ARC) chains as well as monitoring communication in the network, and/or selectively controls whether or not provisioned particular links will be used. One embodiment colors nodes of the network (e.g., a wireless deterministic network) along different paths through the network and marks packets with the color of each traversed node to track a path taken by a packet. One embodiment sends a particular packet through the network and marks over which links the packet traverses and aggregates these traversed links of other copies of the particular packet. One embodiment controls whether or not the provisioned time slots are used based on flooding a control packet through the network with enable or disable information for each of these links.

摘要： One embodiment allocates and uses exclusive and overlapping transmission units in a network. One embodiment includes sending information, from a first network node in a network, during an exclusive transmission unit, wherein the exclusive transmission unit includes one or more wireless time slot-frequency pairings assigned to the first network node to send info nation without another assigned network transmission unit providing overlapping time slot-frequency interference from another network node communicating in the network. One embodiment includes sending information, from the first network node, during an overlapping transmission unit, wherein the overlapping transmission unit includes one or more wireless time slot-frequency pairings assigned to the first network node to send information, with the overlapping transmission unit overlapping in time slot-frequency with one or more other assigned network transmission units that will cause interference if simultaneously used.

摘要： In one embodiment, a network device determines a path from itself to a source device in a computer network, where the source device utilizes the path in reverse to reach the network device. Based on determining a reliability of the path in reverse, the network device may dynamically adjust one or more keepalive parameters for keepalive messages sent on the path. Accordingly, the network device may then send keepalive messages on the path based on the dynamically adjusted keepalive parameters.

摘要： In one embodiment, a security device receives one or more first unique identifications of packets sent by a first device to a second device for which a corresponding acknowledgment was purportedly returned by the second device to the first device. The security device also receives one or more second unique identifications of packets received by the second device from the first device and acknowledged by the second device to the first device. By comparing the first and second unique identifications, the security device may then determine whether acknowledgments received by the first device were truly returned from the second device based on whether the first and second unique identifications exactly match.

摘要： In one embodiment, a path for a sliced tunnel that extends from a head-end node to a tail-end node is computed. The sliced tunnel is furcated into a plurality of child tunnels at one or more fork nodes located downstream from the head-end node. Each child tunnel carries a portion of traffic for the sliced tunnel. The sliced tunnel is merged at one or more merge nodes located downstream from respective ones of the fork nodes. The portions of traffic on the child tunnels are aggregated at the merge nodes. The head-end node sends a signaling message to establish the sliced tunnel along the computed path. The signaling message includes an indication of the one or more fork nodes where the sliced tunnel is furcated into child tunnels and the one or more merge nodes where child tunnels are merged. The head-end node then forwards traffic onto the sliced tunnel.
摘要翻译：在一个实施例中，计算从头端节点延伸到尾端节点的切片隧道的路径。切割的隧道在位于头端节点下游的一个或多个叉节点处分割成多个子隧道。每个子隧道都携带切片隧道的一部分流量。切片隧道在位于相应叉节点下游的一个或多个合并节点处合并。子隧道上的部分流量在合并节点处聚合。头端节点发送信令消息，以沿着计算的路径建立切片隧道。所述信令消息包括所述一个或多个叉节点的指示，其中所述切片的隧道分割成子隧道，以及所述一个或多个合并节点，其中子隧道被合并。然后，头端节点将流量转发到切片隧道。

摘要： In one embodiment, a management device, such as a root node, monitors Internet Protocol (IP) overhead (e.g., IP header sizes during source-routing or route table sizes) within a directed acyclic graph (DAG) in a computer network. If it is determined that the IP overhead is above a configured threshold, then in response, a trigger is initiated to have devices within the DAG label-switch downward traffic directed away from the root node within the DAG. In another embodiment, a device communicating within a DAG stores IP routes corresponding to upward traffic from the device directed toward a root of the DAG, and IP-routes upward traffic based on the IP routes. Conversely, the device also stores labels corresponding to downward traffic from the device directed away from the root of the DAG, and label-switches downward traffic based on the labels, accordingly.

摘要： In one embodiment, routable traffic through one or more border routers between a local computer network and a global computer network is monitored in order to characterize use of one or more global prefixes of the traffic. A particular set of the global prefixes, up to a maximum number, that are most frequently used may be mapped into a set of context identifiers (IDs) having a shorter bit-length than the global prefixes. The context IDs may then be distributed into the local computer network, and the one or more border routers convert between the context IDs and the global prefixes, accordingly.

摘要： In one embodiment, a trigger is signaled to protect a tunnel from a head-end node to one or more tail-end nodes in a computer network via one or more intermediate nodes along the tunnel. One or more receiving nodes along the tunnel receive the trigger, and in response, establish a tunnel connectivity verification session from the receiving node to a corresponding downstream next-next-hop (NNHOP) node along the tunnel. Illustratively, the head-end node may thus recompute a new tunnel path excluding a path segment corresponding to a particular failed tunnel connectivity verification session.

摘要： In one embodiment, a management device receives one or more fate-sharing reports locally generated by one or more corresponding reporting nodes in a shared-media communication network, the fate-sharing reports indicating a degree of localized fate-sharing between one or more pairs of nodes local to the corresponding reporting nodes. The management device may then determine, globally from aggregating the fate-sharing reports, one or more fate-sharing groups indicating sets of nodes having a global degree of fate-sharing within the communication network. As such, the management device may then advertise the fate-sharing groups within the communication network, wherein nodes of the communication network are configured to select a plurality of next-hops that minimizes fate-sharing between the plurality of next-hops.
