In one aspect, a method includes receiving a packet at a first node from a second node, wherein the first node and the second node are part of a network; determining if congestion exists in a primary route used by the packet; processing a packet drop event to establish a secondary route for the packet in response to determining that the congestion exists in the primary route; and restoring use of the primary route if an expiration time has expired. The expiration time is adjusted by an elapsed period and a congestion condition within the network.

Packet rerouting to avoid congestion in a network

Discussed generally are techniques for managing operation of programs in a sequential order. A method can include receiving a query for an image, the query indicating characteristics of the image, selecting a chain of algorithms configured to identify the image based on the characteristics, operating an algorithm of the selected chain of algorithms that operate in increased fidelity order on an input to produce a first result, operating a ground truth algorithm on the input to generate a second result, comparing the first and second results to determine a probability of correctness (Pc) and confidence interval (CI) for the algorithm, and altering the chain of algorithms based on the determined Pc and CI.

Object recognition and detection using reinforcement learning

In one embodiment, a composite Network of Networks is created out of a set otherwise separate constituent networks by a system that includes an operations station and one or more gateways. The operations station is configured to transmit a set of policies for processing data packets travelling through a composite network, where the composite network includes two or more independent constituent networks. The gateways are each communicatively connected between two or more attached constituent networks. A first gateway is configured to receive a data packet from a first constituent network attached to the first gateway; determine one or more real-time network situational awareness characteristics; process the data packet by applying the policies to the data packet based at least in part on the network situational awareness characteristics; and transmit the data packet to a second network attached to the first gateway and distinct from the first constituent network.

Adaptive network of networks architecture

A network system is provided. The network system includes a first network device and a second network device running in data link layer (L2). The first network device includes a first switch and a first PPPoE (Point-to-Point over Ethernet) agent integrally coupled to the first switch. The second network device also includes a second switch and a second PPPoE agent integrally coupled to the second switch. The network system further includes a PPPoE client running in network layer (L3) that communicates to the first PPPoE agent and a PPPoE server in L3 that communicates to the second PPPoE agent. The PPPoE client uses a broadcast (Bcast) MAC address in an initial IPCP (Internet Protocol Control Protocol) negotiation message between the PPPoE client and the PPPoE server.

PPPoE extension over layer 2 switch embedding PPPoE agent

In one aspect, a method includes receiving a data packet at a routing node that includes a processor. The method also includes determining at least one value for the data packet, selecting a routing table from a plurality of routing tables stored at the routing node in response to the at least one value for the packet and forwarding the data packet in response to the routing table selected. Each routing table is associated with a respective one cost function.

Routing a data packet in a communication network

A network gateway device, comprises a tactical data link interface circuit to receive a message from a tactical data link unit in a tactical data link network, the tactical data link unit associated with a unique identifier within the tactical data link network; a message transformation circuit to: extract the unique identifier from the message; and build an Internet Protocol packet using a source address based on the unique identifier; and an Internet Protocol interface circuit to process the Internet Protocol packet toward a destination.

IP address translation for tactical networks

In one embodiment, a method includes receiving a data packet at a routing engine of a node of a network. A route is selected, from a forwarding table of the node, for sending the data packet from the node to a destination of the data packet. The forwarding table includes route characteristics, including route costs, related to two or more routes from the node to the destination. The selected route is analyzed, by a hardware computing device, to determine whether the selected route is suitable to convey the data packet based on real-time traffic information. The data packet is returned to the routing engine if the selected route is determined unsuitable to convey the data packet. An alternate route is selected, from the forwarding table, for the data packet in place of the previous selected route if the previous selected route is unsuitable to convey the data packet.

Network path selection in policy-based networks using routing engine

A method for synchronizing a time reference of a terminal clock of a terminal transceiver including an antenna and a modem, the method including: transmitting, by the modem, a terminal sync hop to a signal relay in accordance with the time reference; searching, by the modem, for a terminal sync hop return from the signal relay near an estimated terminal sync hop receive time; receiving, by the modem, the terminal sync hop return at a terminal sync hop receive time; searching, by the modem, for a master sync hop return from the signal relay; receiving, by the modem, the master sync hop return at a master sync hop receive time; calculating, by the modem, a time difference between the master sync hop receive time and the terminal sync hop receive time; and adjusting, by the modem, the time reference based on the calculated time difference.

Synchronous waveform clock synchronization without a system controller

In one aspect, a method includes receiving, at a first node in a network, a resource reservation request from a second node in the network, determining, at the first node, if there is another node in the network that can be used to reach a destination and meet the resource reservation request and notifying the second node a result of the determining.

Resource allocating in a network

Method for determining link characteristics of a network link including: selecting or configuring one or more existing network traffic packets with one or more requirements when necessary, wherein the one or more requirements include a receiving network node having knowledge about the packets it should receive; transmitting the selected one or more network traffic packets from a transmitting network node to the receiving network node; and examining the transmitted selected one or more network traffic packets to determine the link characteristics of a network link between the transmitting network node and the receiving network node, according to said knowledge about the packets.

Method for indirect link characterization and quality measurement of a digital network

The technology described herein includes a system and/or a method for policy-based data management. The method includes receiving, by a sensor platform device, sensor data from one or more sensors; selecting, by the sensor platform device, one or more screening policies from a plurality of screening policies based on one or more mission parameters and a platform type associated with the sensor platform device; generating, by the sensor platform device, a data set from the sensor data based on the selected one or more screening policies; and transmitting, by the sensor platform device, the data set to one or more computing devices.
