In one embodiment, a method comprises receiving, by a transport layer executed by a processor circuit in an apparatus, an identifiable grouping of data; storing, by the transport layer, the data as transport layer packets in a buffer circuit in the apparatus, the storing including inserting into each transport layer packet a grouping identifier that identifies the transport layer packets as belonging to the identifiable grouping; and causing, by the transport layer, a plurality of transmitting deterministic network interface circuits to deterministically retrieve the transport layer packets from the buffer circuit for deterministic transmission across respective deterministic links, the grouping identifier enabling receiving deterministic network interface circuits to group the received transport layer packets, regardless of deterministic link, into a single processing group for a next receiving transport layer.

Systems and methods for determining locations of wireless nodes in a network architecture are disclosed herein. In one example, an asynchronous system includes a first wireless node having a wireless device with one or more processing units and RF circuitry for transmitting and receiving communications in the wireless network architecture including a first RF signal having a first packet. The system also includes a second wireless node having a wireless device with a transmitter and a receiver to enable bi-directional communications with the first wireless node in the wireless network architecture including a second RF signal with a second packet. The first wireless node determines a time of flight estimate for localization based on a time estimate of round trip time of the first and second packets and a time estimate that is based on channel sense information of the first and second wireless nodes.

A system and computer program product for routing based on user preferences comprising, receiving a routing request from a client device wherein the routing request includes a desired route price and reliability preferences. Determining a plurality of potential packet routes from the routing request and sending a query for potential packet route information to one or more relays in the plurality of potential packet routes. Receiving potential packet route information from each of the one or more relays in the plurality of potential routes and automatically determining an optimal potential packet route based at least on the desired route price, and reliability preferences information.

Techniques for enforcing a common signaling latency between components positioned throughout a data center in order to realize latency equalization even though interconnects between components positioned throughout the data center do not by comparison necessarily exhibit a same total physical length.

A management device managements an optical transmission system provided with a transmission path in which each transmission route between first and second optical transmitting/receiving devices has a different transmission path length. The management device includes collecting unit that registers route delay information indicating a transmission delay time for each of the transmission routes, and collects a measurement delay time being a transmission delay time of the transmission path being measured by the first optical transmitting/receiving device, and identifying unit that identifies the transmission route corresponding to the measurement delay time, based on the route delay information and the measurement delay time.

A plurality of forwarding servers is communicatively coupled to a plurality of sending systems via a network. A first forwarding server associated with a first geographical region includes an interface that receives a first request for a resource from a first sending system via the network. A determination logic determines whether one or more requests that precede the first request are received from the first sending system at a second forwarding server associated with a second geographical region. A causation logic causes the first request to be forwarded to a second endpoint associated with the second geographical region rather than a first endpoint associated with the first geographical region at least partly based on an inference that the first sending system is located in the second geographical region.

In one embodiment, 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.

A physical layer chip of a first physical port of a network device receives a packet and sends a first time stamp and the packet to a Media Access Control (MAC) chip of the first physical port. The MAC chip of the first physical port adds the first time stamp to the packet and sends the packet. A MAC chip of a second physical port receives the packet, extracts the first time stamp of the packet, and sends the packet to a physical layer chip of the second physical port. The MAC chip of the second physical port receives a second time stamp of the packet. The network device calculates a processing delay for the packet. The processing delay is a value obtained by subtracting the first time stamp from the second time stamp.

A satellite communication system includes a communication terminal, and a ground station. The ground station is configured to communicate with the communication terminal through a satellite communication path between the ground station and the communication terminal via a satellite. The ground station includes a diversity switch, and an electronic controller. The diversity switch is configured to switch the satellite communication path from a first satellite communication path to a second satellite communication path different from the first satellite communication path. The electronic controller is configured to determine whether a predetermined switching condition is satisfied based on signal attenuations of the first and second satellite communication paths. The electronic controller is further configured to control the diversity switch to switch the satellite communication path upon elapsing a first predetermined time period after determining that the predetermined switching condition is satisfied.
