摘要:
A method of enabling a user terminal to participate in floor control operations in a telecommunications conference operating a Binary Floor Control Protocol, BFCP. The method includes sending a first message from the user terminal to a gateway node. The first message includes information relating to floor control operations in the conference. The first message is inter-worked at the gateway node to generate a corresponding BFCP message. The BFCP message is forwarded to a Floor Control function.

A network-implemented video processing server (100) generates an immersive video sub-stream by processing video data from at least a portion of multiple video streams carrying video data for a full immersive video scene. The processing is performed based on information representing a user's current field of vision received over a control channel between the network-implemented server (100) and a user device (200). The immersive video sub-stream carries encoded video data corresponding to a sub-portion of the full immersive video scene.

The disclosure relates to a method (50) performed in a distributed cloud network (1) for identifying a network resource of the distributed cloud network (1), wherein the distributed cloud network (1) is divided into a hierarchical distributed system comprising at least a first domain. The method (50) comprises receiving (51), in a first network node (11), a request from a client device (2) for a network resource to be used in providing a service, the request comprising at least one criterion relating to the network resource; resolving (52), in the first network node (11), a first part of the request, the first part corresponding to a first criterion relating to the network resource, thereby identifying one or more domains each comprising at least one network resource fulfilling the first criterion, and sending (53), from the first network node (11) to the client device (2), the one or more identifications corresponding to a respective one or more network resource fulfilling the at least one criterion. The disclosure also relates to method in network node, in client device, and to related nodes and devices.

A method and node (X) are described for use in maintaining a routing table at said node (X) in an overlay network. The routing table of said node (X) contains, for each of a set of neighbouring successor and predecessor nodes (S1-S3, P1-P3), a mapping between an overlay network address of the node and a physical locator of the node. The node (X) periodically exchanges maintenance messages between nodes (A-E, S1-S3, P1-P3) in the overlay network in order to provide updated addressing information for said nodes (A-E, S1-S3, P1-P3). When addressing information is received at said node (X) for a peer node (E) and that peer node (E) is not included within the routing table of said node (X), caching the information at said node (X). In the event that a node (S1-S3, P1-P3) contained within the routing table of said node (X) withdraws from the network, adding the peer node (E) to the routing table using the cached information.

Methods and nodes for enabling and producing input generated by speech of a user, to an application. When the application has been activated (2:1),an application node (200) detects (2:2) a current context of the user and selects (2:3), from a set of predefined contexts (204a), a predefined context that matches the detected current context. The application node (200) then provides (2:4) keywords associated with the selected predefined context to a speech recognition node (202). When receiving (2:5) speech from the user, the speech recognition node (202) is able to recognize (2:6) any of the keyword in the speech. The recognized keyword is then used (2:7) as input to the application.
摘要:
A system (50), node (14, 18, 1200) and method for location aware mass information distribution to peers (14). The method includes overlaying a distributed hash table (DHT) network (52) over an existing physical communication network (30) to which the peers (14) are connected, wherein the DHT network (52) is a peer (14) to peer (P2P) network; providing at least one application layer multicast (ALM) protocol (54) over the overlayed DHT network (52) to form an ALM tree topology (102) for the peers (14), wherein the ALM tree topology (102) is based on location information of the peers (14); using the ALM tree topology (102) for establishing logical connections within a group, between a leader (106) of the group and peers (14) of the group; and using the overlayed DHT network (52) for establishing connections, between the leader (106) and the peers (14), to be followed by a message to be distributed to the peers (14).
摘要:
Apparatus for relaying packets between a first host and a second host. The apparatus comprises a memory for registering for said first host; an address of the first host, a relayed address of the first host, an address of the second host, and an outbound Higher Layer Identifier and/or an inbound Higher Layer Identifier. The apparatus further comprises and one or both of : an outbound packet inspector for inspecting packets received from said first host and addressed to an address of the apparatus to determine whether or not they contain a registered outbound Higher Layer Identifier and, if so, for forwarding the packets to said address of the second host; and an inbound packet inspector for inspecting packets received from said second host and addressed to said relayed address to determine whether or not they contain a registered inbound Higher Layer Identifier and, if so, for forwarding the packets to said address of the first host.
摘要:
A method of maintaining routing tables at nodes of an overlay network, where a routing table of a given node contains, for each of a set of neighbouring successor and predecessor nodes, a mapping between an overlay network address of the node and a physical locator of the node. The method comprises, upon or immediately prior to departure of a node from the overlay network, sending a Leave request from the departing node (or one of the neighbouring nodes of the departing node aware of the departure) to each neighbouring node (or each other neighbouring node of the departing node), indicating the departure and containing one or more mappings for nodes not contained within the routing table of the recipient node. Each neighbouring node (or each other neighbouring node) receives the Leave request and uses said mapping(s) to update its routing table.
