摘要： In one embodiment, a network management system (NMS) determines an intent to initialize a request-response exchange with a plurality of clients in a low power and lossy network (LLN). In response, the NMS adaptively schedules corresponding responses from the clients to distribute the responses across a period of time based on a network state of the LLN. Accordingly, requests may be generated by the NMS with an indication of a corresponding schedule to be used by the clients to respond, and transmitted into the LLN to solicit the responses, which are then received at the NMS according to the indicated schedule.

摘要： In one embodiment, a centralized device for a computer network divides the computer network into one or more regions for which performance is to be measured, and selects one or more nodes within each respective region of the one or more regions. The centralized device may then send a performance measurement request (PMR) to the selected node(s) for each region, and receives measured performance reports from the selected node(s) for each region in response to the PMR. Accordingly, based on the measured performance reports, the centralized device may then adjust at least one of either the divided regions or the selected node(s) for one or more of the one or more regions, e.g., for future PMRs.
摘要翻译：在一个实施例中，用于计算机网络的集中式设备将计算机网络划分成要测量性能的一个或多个区域，并且选择一个或多个区域的每个相应区域内的一个或多个节点。然后，集中式设备可以针对每个区域向所选择的节点发送性能测量请求（PMR），并且响应于PMR从每个区域接收来自所选节点的测量的性能报告。因此，基于所测量的性能报告，集中式设备然后可以调整一个或多个区域中的一个或多个的分割区域或所选择的节点中的至少一个，例如用于将来的PMR。

摘要： In one embodiment, a Transit Information Bloom Filter (TIBF) signal component is generated for use with a routing protocol control message, the TIBF signal component identifying at least one parent node for a corresponding routing topology. The TIBF signal component is encoded in a generated Bloom filter. The parameters of the generated Bloom filter are based at least on one parent node to be encoded and a desired false positive rate for the Bloom filter. The address for each parent node is also encoded in the Bloom filter.

摘要： In one embodiment, a network device selectively operates according to a sparse multicast mode where the network device stores individual devices interested in one or more multicast groups and distributes corresponding multicast group traffic based on the individual devices. Alternatively, the network device selectively operates according to a dense multicast mode where the network device maintains a list of the one or more multicast groups in which at least one device is interested and distributes corresponding multicast group traffic through broadcasting. By determining one or more resource-related characteristics, the network device may then select between operation in the sparse multicast mode and the dense multicast mode based on the resource-related characteristics.

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, 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.
