20100226289 | FLOOR CONTROL IN TELECOMMUNICATIONS CONFERENCE CALLS - 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. | 09-09-2010 |

20110110269 | Maintaining Distributed Hash Tables In An Overlay Network - 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. | 05-12-2011 |
20110296252 | MAINTENANCE OF OVERLAY NETWORKS - A method of managing a ring-based overlay network that is configured to allow routing of messages across an underlying IP network to destinations not specified by an IP address. The method comprises firstly sending a probe message from an initiating node of the overlay network around the ring, with each peer node forwarding the probe message to a successor or predecessor node. Upon detection of a forwarding failure at a node of the ring, a Probe error message is sent from that node to the initiating node. The initiating node represents the final destination for the Probe message. | 12-01-2011 |
20120039453 | EVENT IDENTIFICATION IN PEER TO PEER NETWORKS - A system and method for event notification and access control for Distributed Hash Tables (DHTs) using an event triggering mechanism for DHT-based Peer-to-Peer (P2P) overlay networks is described. According to an embodiment of the invention, a user interested in certain event can insert a trigger into the DHT. When the event occurs, the trigger fires and causes a pre-defined action to be executed. According to another embodiment of the invention, a user peer inserts a trigger resource record, which includes instructions to execute a specified action upon occurrence of the event, into the DHT. A monitored resource record, with which the event is or will be associated, is identified. A monitoring peer, responsible for maintaining the monitored resource record, is then identified. The trigger resource record is maintained at the monitoring peer. | 02-16-2012 |
20130064090 | Load Balancing Method and System for Peer-To-Peer Networks - System and method for balancing a number of incoming connections of nodes connected to a peer-to-peer network. The method includes receiving at a selecting node information about out-finger candidates. The information includes at least a quantifiable parameter for the out-finger candidates and the out-finger candidates are possible nodes to be connected to the selecting node. The method includes calculating in the selecting node, for each node of the out-finger candidates, a probability value by using a predetermined probability function that uses as input the corresponding quantifiable parameter; and selecting one node from the out-finger candidates to be an out-finger node for the selection node based on the probability value. The probability value is associated with a number of in-finger connections to the selected out-finger node. | 03-14-2013 |
20140016471 | LOAD BALANCING MECHANISM FOR SERVICE DISCOVERY MECHANISM IN STRUCTURED PEER-TO-PEER OVERLAY NETWORKS AND METHOD - An overlay network, node and application for load balanced service discovery. The application includes the steps of implementing the service discovery mechanism in the DHT P2P overlay network for finding a peer ( | 01-16-2014 |
20140317196 | METHOD AND ARRANGEMENT FOR THE SUPERVISION OF TRANSACTIONS IN A PEER-TO-PEER OVERLAY NETWORK - The present invention relates to the supervision of transactions in peer-to-peer (P2P) overlay networks. A P2P overlay network often consists of peers interconnected via different access technologies having significant different round-trip time (RTT) delays. Current time supervisions of retransmissions and transactions in P2P networks have fixed values. This has the disadvantages that if the timer values are too short, unnecessary retransmissions are performed although a response would be on its way. If the timer values are too long it results in unnecessarily long messaging delays. These disadvantages have been overcome by a method and a peer for adapting the timer values to the conditions in the P2P overlay network. | 10-23-2014 |
