摘要： Data collected by sensors (10, 30) is transmitted to data collection points (31, 61) over a network using an epidemic protocol in which data received by a relay (3) is forwarded to a randomly-selected group of further relays (4, 5, 6) unless the same data has been previously received by the relay (3) or the data is time-expired. Data received by a relay (3) from different sources (1, 2, 30) in the same time-frame is aggregated using a Bloom filter process so that in each time frame only a single Bloom filter message is transmitted by each relay.

摘要： Methods and apparatus are disclosed for enabling selection of a remote service node from a plurality of possible nodes, each capable of providing a service, and each associated with a service node control entity. The method comprises: receiving a user request in respect of a service required by a user, the request containing a first user device routing identifier relating to the location in the network of the user device, and a service indication indicative of an appropriate service provider; identifying from the service indication a service node control entity associated with the service provider; sending to the service node control entity a service node request containing a second user device routing identifier differing from the first user device routing identifier but selected at least partly in dependence thereon; receiving from the service node control entity an indication of a remote service node capable of providing the required service; and providing an indication of the remote service node to the user device.

摘要： A policy store associated with a policy decision point of an access control system is updated. The policy decision point is arranged to provide, in response to received decision requests, access control decisions in dependence on one or more policies stored in the policy store, each policy specifying a predetermined access control decision to be provided in response to a particular access request made in respect of a particular attribute or combination of attributes. The policy decision point is associated with at least one policy enforcement point arranged to implement access control in accordance with access control decisions provided by the policy decision point in response to decision requests submitted by the policy enforcement point, the policy enforcement point having associated therewith an attribute store providing data relating to attributes in respect of which access requests have previously been made via the policy enforcement point.

摘要： The method involves transmitting to receivers receiving a multicast a plurality of requests for feedback (3), each request including a probability parameter (P). Each terminal replies to this (or not) with a corresponding probability (4). One then counts the number (r) of replies to each request (5); determines, from the counts and parameters, estimates of the number of receivers (6); and filters the estimates (7). The method further includes repeatedly computing a new probability parameter to be included in a subsequent feedback request, by forecasting, from the counts and parameters, a upper bound for the number of receivers (9, 10, 11) and determining from this the new probability parameter (12) such that the risk that the number of replies exceeds a predefined threshold is kept below a predefined value.
