Abstract: A method includes obtaining performance characterization values from endpoints managed by a first fog node at a first hierarchical level in a hierarchy of fog nodes. The method includes changing a first operating characteristic of the wireless network based on the performance characterization values. The first operating characteristic affects the operation of one or more of the endpoints. The method includes transmitting a portion of the performance characterization values to a second fog node at a second hierarchical level in the hierarchy of fog nodes. The method includes changing a second operating characteristic of the wireless network based on an instruction from the second fog node. The second operating characteristic affects the operation of the first fog node and/or other fog nodes at the first hierarchical level. Changing one or more of the first operating characteristic and the second operating characteristic satisfies an operating threshold for the wireless network.

Abstract: Presented herein are segment-routing methods and systems that facilitate data plane signaling of a packet as a candidate for capture at various network nodes within a segment routing (SR) network. The signaling occurs in-band, via the data plane—that is, a capture or interrogation signal is embedded within the respective packet that carries a user traffic. The signaling is inserted, preferably when the packet is classified, e.g., at the ingress node of the network, to which subsequent network nodes with the SR network are signaled to capture or further inspect the packet for capture.

Abstract: Presented herein are methods and systems that facilitate data plane signaling of a packet as a candidate for capture at various network nodes within an IPv6 network. The signaling occurs in-band, via the data plane—that is, a capture or interrogation signal is embedded within the respective packet (e.g., in the packet header) that carries a user traffic. The signaling is inserted, preferably when the packet is classified, e.g., at the ingress node of the network, to which subsequent network nodes with the IPv6 network are signaled to capture or further inspect the packet for capture.

A control system receives the energy management instructions using them to control energy to all loads.

Abstract: A network device receives a data packet including a source address and a destination address. The network device drops the data packet before it reaches the destination address and generates an error message indicating that the data packet has been dropped. The network device encapsulates the error message with a segment routing header comprising a list of segments. The first segment of the list of segments in the segment routing header identifies a remote server. The network device sends the encapsulated error message to the remote server based on the first segment of the segment routing header.

Abstract: In one embodiment, an intermediate node, of a multi-stage process path through a computer network, receives a workload message with an associated latency budget to complete the multi-stage process at a final stage device. In response, the intermediate node determines a current latency from an initial stage device for the workload message to the receiving of the workload message, and also determines a remaining portion of the latency budget based on the current latency. In response to the remaining portion of the latency budget being less than expected at the intermediate node, the intermediate node may perform one or more latency-reducing actions, and then transmits the workload message toward the final stage device.
