International Classification:

G06F 15/16

US Classification:

709231

Abstract:

A server-side adaptive streaming capability is provided. The server-side adaptive streaming capability supports adaptive streaming of a data object from a server toward a client via a Transmission Control Protocol (TCP) connection between the server and the client. The server has access to a plurality of versions of the data object having a respective plurality of encoding bit rates associated therewith. The server has a TCP congestion control mechanism running for the TCP connection. The TCP congestion control mechanism has information associated therewith. The server determines, using the information associated with the TCP congestion control mechanism running on the server for the TCP connection, a transmission bit rate expected to be supported by the client for the TCP connection. The server selects, based on the transmission bit rate expected to be supported by the client and the encoding bit rates associated with the versions of the data object accessible to the server, one of the plurality of versions of the data object for propagation from the server toward the client via the TCP connection. The server dynamically switches between the versions of the data object as the transmission bit rate expected to be supported by the client changes.

US Classification:

370392

Abstract:

Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, at the network node, a packet including a destination address of the packet; resolving the destination address of the packet to a first address of a first receiving node; identifying a second address of a second receiving node as being associated with the first address; and transmitting the packet to both the first address and the second address.

Assignee:

ALCATEL LUCENT - Paris

International Classification:

H04L 12/56

US Classification:

370390

Abstract:

Avoiding duplicative forwarding of multicast traffic is disclosed. A join message received at a first router is directed to a peer router of the first router from a first downstream node of the first router and the peer router without passing through the peer router. The join message indicates that one or more downstream nodes of the peer desire to receive from the peer multicast traffic specified in the join message. It is determined whether the join message from the first downstream node to the peer would result in duplicative forwarding by the peer of multicast traffic from an upstream source upstream of the peer and the first router based on the join message. Based at least in part on a determination that the join message would result in duplicative forwarding of the multicast traffic, an election procedure is initiated to avoid such duplicative forwarding of the multicast traffic.

Abstract:

A method for securing communications for a given network is provided. The method comprises by at least one node(i) of the network configured to utilize pairwise keys: generating a set of encryption keys; and transmitting the set of encryption keys to a controller for the network; by the controller, executing a key selection process wherein for each node(j) in the network an encryption key J is selected from the set of encryption keys; assigning the encryption key J to the node(j); and transmitting the selected encryption key J to the node(j); by each node(j), generating an encryption key I to the node(i); and sending the encryption key I to the node(i) via the controller.
