Abstract: A method for real time monitoring of at least one TCP flow involves monitoring TCP packets flowing past a particular point in a TCP network. A flow trace including at least source and destination addresses for each TCP packet is determined and a packet record for each monitored TCP packet within a determined flow trace is created. Each of the packet records includes at least a transmitted order number and an actual received sequence number, from which an expected received sequence number for each packet record is determined and stored in the packet record. The difference between the expected received sequence number for each packet record and the expected received sequence number for the previous packet record is used to thereby determine by how much a particular packet was moved out of sequence.

Abstract: A mobile communications system comprising a radio access network having a multiplicity of network sites organised in a multi-layered hierarchy and a traffic flow management system for controlling the routing of traffic flow through the network. The management system trades resource at the various network sites against a plurality of user Quality of Service parameters to achieve required contractual levels of commitment to a multiplicity of users.

Abstract: The present invention relates to a communications environment comprising a digital marketplace arrangement which enables user to have dynamic access to a variety of network operators and service operators which are registered with the marketplace. The users can communicate with the digital marketplace via a logical market channel enabling user, service providers and network operators to interact in real time and negotiate for appropriate communication links and quality of service. Each communications environment may comprise more than one digital marketplace.

Abstract: The present invention relates to a telecommunications service provision manager that is configured to allow access to a plurality of telecommunications services to determine the location of a service and control execution of that service.

Abstract: A mobile communications network (20) comprises a local exchange (24) or mobile switching center effectively connected to a plurality of cell site switches (22), each cell site switch (22) being effectively connected to a cluster (14) of base station transceivers (13). The connection between each cell site switch (22) and the respective cluster (14) is formed by a common bus (21) to which each base station transceiver (13) in the cluster and the pertaining cell site switch (22) is directly connected.
