Abstract: The invention relates to a computer system and method for high availability processing through a session on a transport connection, for use in a cluster with at least two nodes. The system comprises a protocol component; a cluster with at least two nodes, said cluster being arranged for running the protocol component; and a server arranged for maintaining a protocol session on a transport connection with a node of the cluster. The cluster is arranged for maintaining on each of said at least two nodes one instance of the protocol component, so that at least two instances are active; the server is arranged for simultaneously maintaining a protocol session with each instance.

Abstract: The present invention relates to home devices such as set-top boxes, and more particularly to methods providing autonomous file transfers to and from such home devices. There is provided a method for spreading notifications pertaining to the completion of file transfers in time. The method is based on the concept of imposing different delay times on different devices, which delay times must be observed prior to notifying the server of a file transfer completion.

Abstract: The invention relates to a method of performing multicast admission control in a communications network (1?), comprising the steps of: a) receiving, at a first node (1-1) of the communications network (1?), a request (6) for a multicast channel (4b) from a host system (5b) communicatively coupled to the first node (1-1); b) sending, by the first node (1-1), a request (6) for the multicast channel (4b) to a central admission controller (7) of the communications network (1?), the sending of the request (6) being triggered by receiving the request (6) from the host system (5b); c) determining, by the central admission controller (7), if sufficient resources exist on nodes (1-1 to 3-1) and interconnecting links (1.1 to 3.

Abstract: A data communication system is disclosed, comprising a network provided with a control server for managing network resources, and a delivery server for delivering multimedia content to one or more UE (user equipment) devices, wherein the control server is arranged to pass a network session ID, of a network session between the delivery server and the UE device, to the delivery server, and the delivery server is arranged to keep track of the network session independently of the control server, such that once the network session ID of the network session has been passed to the delivery server, the control server keeps no reference to the network session and takes no part therein.

Abstract: In one embodiment, a method for alarm notification between a customer premises device and a remote management server interfacing with each other through a remote management protocol, includes detecting an alarm condition in the customer premises device, and transferring an explicit alarm notification from the customer premises device to the remote management server over the remote management protocol. The remote management server responds to the explicit alarm notification.

Abstract: Method for configuring a client (C1, C2) of a communication network (N), comprising: a first step consisting in having the client send a request (MR1, MR2) to a server (S) adapted to dynamically determine an IP address a second step consisting in having the server sending a reply message (MA1, MA2) backward; and, wherein said client uses said IP address in subsequent IP datagram (MS1, MS2) sent through the communication network. The method is new in that the server determines a realm associated with the client, and includes an identifier of this realm within the reply message. This identifier is included by the client in the subsequent IP datagrams.

Abstract: A traffic engineering module of a telecommunication device in a telecommunication network. The traffic engineering module determines traffic distribution and traffic share for each one of a set of paths between a source and a destination of the telecommunication network. The traffic distribution is adjusted on at least one of: a timer expires, receipt of load-losses information related to the critically-loaded link. The traffic engineering module includes first determining module determining for each path an equivalent load as a function of received load information and received losses information of the path, and provides thereby a set of equivalent loads; second determining module determining a maximum equivalent load out of the set of equivalent loads; and third determining module determining for each of the path an increase in traffic share proportional to a difference between the maximum equivalent load and the equivalent load of the path.

Abstract: A Traffic engineering means of a telecommunication device in a telecommunication network, said traffic engineering means being enabled to determine a traffic distribution being a traffic share (TSi) for each one of a set of paths (P1, P2, P3) between a source (S) and a destination (D1, D2) of the telecommunication network, where the traffic distribution being adjusted on at least one of the following events: a timer expires, load-losses information related to the critically-loaded link has been received, and wherein the traffic engineering means comprising first determining means (60) enabled to determine for each path (Pi) an equivalent load (EquivLoadpath 1) as a function of received load information and received losses information of said path (Pi), and to provide thereby a set of equivalent loads ((EquivLoadpath 1), (EquivLoadpath 2); . . .
