A method and apparatus for peer-to-peer file sharing is provided. In some embodiments, the method includes receiving a request for a list of neighbor peers, where the request is made by a requesting peer device, and where the requesting peer device has a local internet service provider (ISP). The method may also include employing a server device to rank each neighbor peer in a plurality of neighbor peers based on whether the respective neighbor peer is external to the local ISP, and if the respective neighbor peer is external to the ISP, further based on a cost metric associated with a next ISP hop from the requesting peer device to the respective neighbor peer. The method may also include generating the list of neighbor peers based on the ranking of the neighbor peers, and enabling transmission of the list of neighbor peers to the requesting peer device.

Price-aware neighborhood selection for peer-to-peer networks

A method and system of analyzing a network to identify a network defect allows user selection of traffic subset to be recorded. After recording the selected traffic subset of the network traffic during network operation, the recorded traffic is then replayed at least in part to the network to replicate, and thus assist in identifying, the network defect.

Virtualization and replay-based system for network debugging

A method for routing-assisted traffic monitoring includes providing a set of flows, each flow having an associated ingress routing device and an associated egress routing device. A controller determines a micro-flowset routing for the set of flows, the micro-flowset routing defining which of a set of directed links connecting a plurality of routing devices are used to route each of the flows from the respective ingress routing device to the respective egress routing device. The controller transmits flow information to at least a first routing device of the plurality of routing devices according to the micro-flowset routing, the flow information defining which of the set of directed links are to be used to route at least one flow entering the first routing device to a second routing device of the plurality of routing devices.

Method for routing-assisted traffic monitoring

A method and apparatus for communicating over a network is provided. The method includes obtaining building block codes, where the building blocks codes are capable of being used together to provide an end-to-end service. The building block codes are sent to each appropriate building block controller, where each building block controller is associated with a corresponding network node. Upon receiving a first packet of a connection for the first end-to-end service, a determination as to which network nodes of the plurality of network nodes should be used as network hops for the connection, and as to, for each network node that should be used as a network hop for the connection, which building block codes should be used by the building block controller corresponding to the network node. These determinations are communicated to each of the appropriate building block controllers.

Apparatus, method, manufacture, and system for providing network services from building blocks

A network may include a plurality of nodes forming a first layer and a sub-set of the plurality of nodes forming a second layer. The first layer may follow a first routing objective in routing traffic, and the second layer may develop constraints based on the first routing objective and follow a second routing objective within the developed constraints in routing traffic. In another network, the second layer may follow a second routing objective in routing traffic, and the first layer may develop constraints based on the second routing objective and follow a first routing objective within the developed constraints in routing traffic.
