摘要:
A distributed payment system integrated in network resources allows for the distributed processing of digital currency transactions in existing network elements and allows for each node to act as a revenue source by charging for provided services. The systems and methods can provide a requesting entity the means for payment of use of the network resources of a provisioning entity. The network resources that are used can enable the provision of services that can include packet routing and forwarding, access to resources such an antennae and delivery of content.

Methods and apparatus for distributing link state information are provided. Network nodes propagate link state information via a control plane flooding operation. A first network node can initiate this propagation in response to a local link state change. In addition, some network nodes can via data plane messaging to transmit link state information to a remote node of the network. The remote node responds to the message by initiating a control plane flooding operation at that location. The remote node can be selected based on a variety of criteria, such as network traffic conditions, location, or network topology. Multiple remote nodes can be prompted in this manner to initiate flooding operations.

A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a next node belonging to the limited portion of the network and located along an available network path between the node and the target node is determined, and the packet is forwarded to the next node.
摘要:
A method in a mobile network including a first node configured to receive packets through a point-to-point tunnel from a second node. The method comprises a third node performing steps of: accessing tunnel information identifying the point-to-point tunnel; encapsulating a packet using a tunnel header containing the accessed tunnel information; and sending the encapsulated packet to the first node.

One aspect of the disclosure is directed to a system and method for determining the propagation delay for a signal to traverse an optical fiber between two transceivers. The method is performed by the first transceiver and includes transmitting a message to the second transceiver over a first optical fiber. The method further includes receiving on the first optical fiber a reply message from the second transceiver including an indication of the internal time for the second transceiver to transmit the reply message. The method further includes determining the time interval from the time the message was transmitted to the time the first transceiver received the reply message. The method further includes calculating the propagation delay from the time interval and the internal time. The method further includes configuring the first transceiver to receive data traffic from the second transceiver on a second optical fiber. Another aspect is directed to a system and method for using the determined propagation delay to synchronize the two transceivers.
摘要:
A method and apparatus for connecting/attaching a mobile device to a network. Service information, such as pricing and plan information, associated with one or more networks is provided to a mobile device. The mobile device requests and receives configuration details for a selected one of the networks. The configuration details can include identity information such as is stored in a reprogrammable SIM, usable for connecting/attaching the mobile device to the selected network. The mobile device then registers and connects with the selected network based on the configuration details.
摘要:
Routers using virtual routing and forwarding nodes to implement a service fabric of service chains. The router may configure M+1 virtual routing and forwarding instances, M being an integer representing a number of a plurality of service appliances in a data center network. Each virtual routing and forwarding instance may be associated with a routing table of routing rules to define various service chain routing paths. The routing rules are based on destination addresses in data packets.

A service description may be used in network virtualization in order to specify requirements of an application. In order to provide network virtualization for generic networking components, including legacy networking components, the service description is mapped to a logical network implementation and then subsequently mapped to a physical implementation.
摘要:
A method and apparatus route data packets in communication network. A current routing topology of the network is analyzed and a digest value representing the current routing topology is determined. The digest value is encapsulated within the data packet. The data packet is forwarded according to the current routing topology.
摘要:
A system, method and apparatus synchronize protocol events in a distributed communication network. The network includes a plurality of nodes. Each node in the network includes a time source which maintains a clock signal synchronized with each other node time source in the network. An announcement of a protocol event is sent to at least one node. The announcement includes a predetermined time for implementing the protocol event. The protocol event is acted upon at the predetermined time.
