摘要： In one embodiment, a particular device determines a selected link from the particular device toward a root device in a computer network, wherein traffic destined away from the root device via the particular device utilizes the selected link in reverse. By monitoring a link quality of the selected link in reverse based on received traffic over the selected link, the particular device may determine whether the link quality is below a lower threshold. In response to the link quality being below the lower threshold, the particular device activates use of keepalive messages from the particular device over the selected link.

摘要： According to one or more implementations of the disclosure, packets may be transmitted in a low power and lossy network (LLN) by receiving, on a first node, a message from a sending node, and by activating a critical message configuration to be applied in routing the message. A message identifier (e.g., signature) for the message may also be received or gleaned. The message identifier can be compared at the first node to a list of stored message identifiers, created based on routing history, to determine if the message has already been received. As such, if the message has not been received at the first node previously, a first parent and a second parent for the message are identified and the message, along with the critical message indication, can be transmitted to the first parent and the second parent, thereby achieving redundancy in the routing of the message.
摘要翻译：根据本公开的一个或多个实现方式，分组可以通过在第一节点上从发送节点接收消息并且通过激活要应用的关键消息配置来在低功率和有损网络（LLN）中发送路由消息。消息的消息标识符（例如，签名）也可以被接收或收集。可以将消息标识符在第一节点处与基于路由历史创建的存储消息标识符列表进行比较，以确定消息是否已经被接收。因此，如果先前还没有在第一个节点处接收到消息，则识别该消息的第一个父节点和第二个父节点，并将该消息连同关键消息指示一起发送到第一个父节点和第二个父节点从而在消息的路由中实现冗余。

摘要： In one embodiment, a network server layer provides disjoint channels in response to client-layer disjoint path requests. For example, the network layer can be an optical network, and the client layer may be a packet switching layer (e.g., label switching, Internet Protocol). In one embodiment, a server-layer node receives a client-layer disjoint path request to provide a server-layer channel through a server-layer network. The client-layer disjoint path request includes an identifier corresponding to an existing client-layer path that traverses a current channel through the server-layer network that does not include the server-layer node. The server-layer network determines a particular channel through the server-layer network that is disjoint to the current channel based on route information of the current channel, and then signaling is performed within the server-layer network to establish the particular channel.

摘要： In one embodiment, certain nodes in a computer network maintain a plurality of routing topologies, each associated with a different corresponding delay (e.g., dynamically adjusted). Upon receiving a packet with an indicated delay budget at a particular node, the node updates the delay budget based on an incurred delay up to and including the particular node since the indicated delay budget was last updated, and selects a particular routing topology on which to forward the packet based on the updated delay budget and the corresponding routing topology delays. The packet may then be forwarded with the updated delay budget on the selected routing topology, accordingly.

摘要： In one embodiment, sensor data is transported in a network to a rendezvous point network node, which consolidates the information into a consolidated result which is communicated to the destination. Such consolidation by a network node reduces the number of paths required in the network between the sensors and the destination. One embodiment includes acquiring, by each of a plurality of originating nodes in a wireless deterministic network, external data related to a same physical event; communicating through the network said external data from each of the plurality of originating nodes to a rendezvous point network node (RP) within the network; processing, by the RP, said external data from each of the plurality of originating nodes to produce a consolidated result; and communicating the consolidated result to a destination node of the network. In one embodiment, the network is a low power lossy network (LLN).

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.
