  • Patent number: 9258218
    Abstract: A software-defined network overlay capability is configured to control one or more overlay networks using software-defined networking (SDN) in which control functions and forwarding functions are separated. The software-defined network overlay capability may be configured to vertically move packets across network layers, e.g., into an overlay network (e.g., into a tunnel via encapsulation), out of an overlay network (e.g., out of a tunnel via decapsulation), or the like. The software-defined network overlay capability may be configured to move packets from native forwarding infrastructure into an overlay network, between overlay networks (e.g., into a first overlay network from a second overlay network without leaving the second overlay network, out of a first overlay network and into a second overlay network, out of a first overlay network while remaining within a second overlay network, or the like), from an overlay network onto native forwarding infrastructure, or the like.

  • Patent number: 9072041
    Abstract: Various exemplary embodiments relate to a method for transmitting data packets in a cellular network to a user equipment using a first distributed access gateway, including: receiving a first tunnel request from a second distributed access gateway; establishing a first tunnel with the second distributed access gateway; receiving a first data packet destined to the user equipment from a native packet transport network; and transmitting the first data packet to the user equipment via the first tunnel to the second distributed access gateway.

  • Patent number: 9055082
    Abstract: Provided is a method for localizing content in a peer-to-peer network. The method includes receiving a message announcing first content. Storing a <key, value> pair in a table based on the message. The key represents content information and the value represents node information. The node information identifies a node announcing the content, and the content information identifying the content. Storing a plurality of first variation keys in the table. Each of the plurality of first variation keys being a variation of the stored first key. The method further includes intercepting a request message and sending a response to a sender of the request message. The response message including the list of nodes, the list of nodes based on a key based on a destination address of the request message and the table.

  • Patent number: 8949329
    Abstract: Provided is a method for content popularity extraction from a distributed hash table (DHT). The method includes receiving, by a first node, a request message from a second node of a peer-to-peer network. Accessing, by the first node, information associated with the request message, the information indicating a content item and a content demand. And determining, by the first node, a content popularity of a plurality of content items based on the information.

  • Patent number: 8626854
    Abstract: Provided is a method for localizing peer-to-peer traffic. The method includes transmitting, by a first node of a peer-to-peer network, a first message to one or more other nodes associated with the peer-to-peer network. The message includes a request for content and a deadline for when the content is to be received by the first node.

  • Patent number: 8539099
    Abstract: In one embodiment, the method includes receiving a content request from the end user at a proxy. A modified TCP connection request message is generated such that the modified TCP connection request message includes a content identifier. The content identifier identifies the requested content. The modified TCP connection request message is sent from the proxy towards an origin server associated with the requested content, and a response to the TCP connection request message is received from a network element. A TCP connection is established with the network element.

  • Publication number: 20130166739
    Abstract: A method of processing peer-to-peer requests is provided. The method may include; storing, at a network element, peer information in a database for each peer of a plurality of peers, the peer information indicating at least one ISP associated with the peer and the content contained by the peer, receiving a request for content from a requester, and sending a response to the content requester based on the ISP with which the requester is associated and the stored peer information.

  • Publication number: 20130159374
    Abstract: The distributed message handling system is created by using session states to represent the plurality of session contexts in the message handling system. The session states are flat representations of the session context which completely describe the session. Utilizing the session states to handle system message requests allows the message handling system to distribute the handling of the message requests to a plurality of state machines. Advantageously, the distributed messaging system allows the message handling system to dynamically allocate message handling resources to application instances based on demand. Such dynamic allocation allows providers to efficiently allocate resources to meet demand while meeting application execution demands.

  • Publication number: 20120185595
    Abstract: Provided is a method for localizing peer-to-peer traffic. The method includes receiving, by a first node, a request message from a second node of a peer-to-peer network. The method includes accessing a table based on the request message to determine if the second node is associated with a local network. The table stores a plurality of keys and node information indicating a relationship between the first node and the local network. The node information is stored in relation to each of the plurality of keys. The method includes transmitting a response message to the second node if the second node is associated with the local network.
