    Abstract: In one embodiment, a device (e.g., path computation device) informs a network management device of a plurality of possible probing profiles, where nodes of a computer network receive the plurality of possible probing profiles from the network management device. Based on determining that particular information is desired from one or more particular nodes of the nodes of the computer network, the device may then select one or more particular probing profiles of the plurality of possible probing profiles based on the particular information, and instructs the one or more particular nodes to probe one or more particular destination nodes according to the one or more particular probing profiles.

    Abstract: In one embodiment, a device in a network receives one or more time slot usage reports regarding a use of time slots of a channel hopping schedule by nodes in the network. The device predicts a time slot demand change for a particular node based on the one or more time slot usage reports. The device identifies a time frame associated with the predicted time slot demand change. The device adjusts a time slot assignment for the particular node in the channel hopping schedule based on predicted demand change and the identified time frame associated with the predicted time slot demand change.

    Abstract: In one embodiment, a switch in a computer network may receive a neighbor solicitation (NS) message for a target node for which no neighbor authentication (NA) reply has been received at the switch. The switch may then determine whether to forward the NS message to only non-constrained links of the switch, or to both non-constrained links and constrained links of the switch. The determining may be configured to intermittently result in forwarding the NS message for the target node to both the non-constrained links and the constrained links. The switch may then forward the NS message according to the determination.

    Abstract: In one embodiment, an agent device discovers a set of path computation elements (PCEs) and corresponding available capabilities and resources, and determines particular capabilities and resources of interest in a particular computer network. Upon building a simplified view of the available capabilities and resources of the set of PCEs based on the particular capabilities and resources of interest, the agent device advertises the simplified view of the available capabilities and resources into the particular computer network.

    Abstract: Techniques are presented herein for use in a Time Division Multiple Access (TDMA) communication system in which devices send transmissions to each other in time slots during a time frame. A plurality of time slots is allocated for a first device to send traffic to a second device. The first device includes in a transmission during at least one of the plurality of time slots an indicator configured to indicate whether a next time slot in the plurality of time slots is used for traffic from the first device to the second device. Thus, the actual usage of a next time slot in a sequence of a plurality of time slots may be dynamically determined by the transmitting device so that the receiving device(s) need not be in the idle listening mode for the next time slot, thereby saving power.

    Abstract: In one embodiment, an access point is configured with a plurality of resource units (RUs). Each RU is configured to use a frequency range that differs from frequency ranges used by the other RUs. The access point determines a pattern of recurring signal performance over time. For each RU of the plurality of RUs, the pattern indicates the recurring signal performance with respect to a station when the station is located in a given physical location. The access point allocates one or more of the RUs for communicating with the station. The pattern is used for avoiding allocation of any of the RUs for which the station is predicted to experience strong multipath fading or other destructive interference.
