A method including determining how many optical channel (OCh) paths are available for border node pair connections; determining which of the OCh paths satisfy a preselected latency threshold; and reporting the OCh paths that satisfy the preselected latency threshold to a service coordinator.

A method for validating a time function in a network of a vehicle includes: ascertaining a receiving time of a sync message of a master; receiving a follow-up message of the master; ascertaining a receiving time of a further sync message of the master; receiving a further follow-up message of the master; determining a time function of the first client based on the receiving time of the sync message, the receiving time of the further sync message, the transmission time of the follow-up message, and the transmission time of the further follow-up message; ascertaining a synchronized transmission time of a path delay request message from the first client to the master; ascertaining a synchronized receiving time of a path delay response message from the master; receiving a path delay response follow-up message from the master by the first client; and validating a time function of the master.

In one embodiment, a traffic management system includes an input/output sub-system to receive route search requests from client devices, and a CPU to search a route database for a suitable match for the route search requests yielding routes. The input/output sub-system is operative to receive data related to traffic levels along the routes. The CPU is operative to calculate a score for each route, select N quickest routes, and allocate the N quickest routes among the client devices. A first and second client device are allocated a first and second quickest route from the N quickest routes, respectively, the first and second quickest route having a first and second score, respectively. The second score is different to the first score. The input/output sub-system is operative to send to each client device data about the route allocated to that client device. Related apparatus and methods are also described.

The setting of a value of the transmission control parameter for a transmission of data on a multi-hop relay radio link of a cellular network is controlled. Said controlling is based on a route time of a packet transmitted between end nodes of the multi-hop relay radio link. E.g., the transmission control parameter may relate to a property of an Automatic Repeat Request protocol.

Described embodiments provide systems and methods for zone selection for distributed services. A device records latency data measured for interactions between each of a plurality of clients and a service hosted by servers in two or more zones. The device directs network communications from each of the plurality of clients to respective servers hosting the service based on zones assigned to each of the plurality of clients. The device assigns clients to zones based on the recorded latency data. For example, the device identifies a grouping for a client, determines whether the recorded latency data indicates that latency for clients in the grouping is increasing faster than a threshold rate, and selects, responsive to the determination, a zone indicated by a selected set of recorded latency data as lowest in latency.

Systems and methods for gathering data by an access point in a Wi-Fi system for optimization include periodically or based on command from a cloud-based system performing one or more of i) obtaining on-channel scanning data while operating on a home channel and ii) switching off the home channel and obtaining off-channel scanning data for one or more off-channels; and providing measurement data based on one or more of the on-channel scanning data and the off-channel scanning data to the cloud-based system for use in the optimization of the Wi-Fi system, wherein the measurement data comprises one or more of raw data and processed data.

These techniques introduce various walker agents that may physically move between different executing nodes/devices within the network. More specifically, a device in a network receives a path computation agent configured to determine a path in the network that satisfies an objective function. The device executes the path computation agent to update state information regarding the network maintained by the path computation agent. The device selects a neighbor of the device in the network to execute the path computation agent based on the updated state information regarding the network. The device instructs the selected neighbor to execute the path computation agent with the updated state information regarding the network. The device unloads the path computation agent from the device after selecting the neighbor of the device to execute the path computation agent.

This application discloses a neural network that also functions as a packet data network using an MPLS-type label switching technology. The neural network uses its intelligence to build and manage label switched paths (LSPs) to transport user packets and solve complex mathematical problems. This architecture is well suited to interconnect large numbers of processors or computers into a neural network exhibiting advanced intelligence which can be used for complex activities such as managing the power grid. However, the methods taught here can be applied to other data networks including ad-hoc, mobile, Information Centric, Content Centric, Sensor, and traditional IP packet networks, cell or frame-switched networks, time-slot networks and the like.

An embodiment of network coordinator apparatus may include a node provisioner to provision each of a plurality of low power nodes, a node associater to create a first association for each of the plurality of lower power nodes, and a node coordinator communicatively coupled to the node provisioner and the node associater to coordinate the plurality of lower power nodes.

A method operates a software defined network that has a number of data plane elements having flow table entries that define forwarding functions of the data plane elements; and at least one control plane element for programming the forwarding functions of the data plane elements by instructing the data plane elements to install appropriate flow table entries. The method includes: obtaining, by the data plane elements, flow table entry installation time information and making this information available directly or indirectly to the at least one control plane element; and using, by the at least one control plane element, the flow table entry installation time information for deciding on which of the data plane elements to install a particular flow table entry and/or when to transmit an instruction to one or more of the data plane elements to install a particular flow table entry.
