    • A method, program and user node for use in a communication system implemented over a network comprising a plurality of user nodes, each being associated with a respective presence status indicating an availability of the user node for communication within the communication system. The method comprises, at each of a first one or more of the user nodes: maintaining a contact list specifying a selection of contacts from the plurality of user nodes; associating a presence update priority level with each of the contacts, the presence update priority level relating to an estimated likelihood of communication between the first user node and the respective contact; and transmitting a presence message to each of a plurality of the contacts in dependence on the respective presence update priority level, each of the presence messages comprising at least one of: a request for the presence status of the contact, and a notification of the presence status of the first user node.

    • A method of transmitting a data stream to end-user nodes of a network, and a corresponding communication system, program, and distribution system for distributing the program. The method comprises: for each of a plurality of possible combinations of routes of the stream to a plurality of consuming end-user nodes, evaluating a utility function for each of the consuming end-user nodes, the utility function being dependent on route and defining a quantitative measure of end-user benefit that would be experienced at the respective end-user node by consumption of the stream; for each of the plurality of possible combinations of routes, determining an overall utility value based on the respective evaluation of the utility functions of each of the plurality of consuming end-user nodes; and selecting a preferred combination of routes for the stream based on the overall utility values of the different possible combinations.

    • A method, system and program for routing a data stream amongst a plurality of network nodes including at least a plurality of end-user nodes. The method comprises: establishing a plurality of routes for the stream to a plurality of consuming end-user nodes, including at least one route via one or more relaying nodes; at each of a plurality of optimising nodes, executing an optimization algorithm to determine a respective routing modification by evaluating a routing criterion with respect to a collection of end-user nodes which share information with the respective optimising node and determining a change in the routing criterion that would result from one or more potential routing modifications. The different optimising nodes' collections of end-user nodes are at least partially coincident such that each optimising node can determine a different routing modification with respect to at least some of the same end-user nodes.
    • 一种用于在包括至少多个最终用户节点的多个网络节点之间路由数据流的方法,系统和程序。 该方法包括:通过一个或多个中继节点向多个消费的最终用户节点建立流的多条路由,包括至少一条路由; 在多个优化节点中的每一个处,执行优化算法以通过评估相对于与相应优化节点共享信息的最终用户节点的集合的路由标准来确定相应的路由修改,并且确定路由准则的变化 这将导致一个或多个潜在的路由修改。 最终用户节点的不同优化节点的集合至少部分重合,使得每个优化节点可以针对至少一些相同的最终用户节点确定不同的路由修改。
