摘要: A non-geostationary satellite connection-less network incorporates a plurality of satellite nodes and ground stations in communication with the nodes. The network is modelled by the corresponding virtual model network. In the virtual network, connections between users are available between virtual nodes and are made according to a restricted set of routing plans based on the modelled virtual paths between those nodes. The virtual model provides a means of determining admission of connection-orientated calls of different quality of service (QoS) traffic class requirements into the network with engineered grade of service (GoS) and QoS guarantees.

摘要: A telecommunications system comprises an asynchronous transfer mode (ATM) network having uncommitted bandwidth, and a plurality of adaptive grooming routers (AGR) coupled to the network. The AGRs comprise a group adapted to function as a virtual transit exchange whose fabric and control are distributed over the group. The virtual comprising the AGRs incorporates independent connection control and call routing functions and has means for determining the current system status whereby to set up narrow band connections across the ATM network based on that status determination.

摘要: In a packet communications network, e.g. an IP network, connection oriented services are carried in user tunnels which are set up in engineering tunnels established across the network. This provides end to end connectivity without the need for individual packet routing at the intermediate network nodes.

摘要: Narrowband subscriber terminals (40, 52, 58) of different narrowband networks are interconnected via a broadband network (48) that supports dissimilar signalling protocols to those maintained on the respective narrowband networks (40, 52, 58). A call server in a first narrowband network (40), in response to a call (100) from a first subscriber terminal (12) to a second subscriber terminal (68) in a second but different narrowband network (52), selects a phantom trunk (202) between the two networks. The phantom trunk has a unique circuit identity, which circuit identity is used in a first instance to relay to the second network an address of the second subscriber terminal (68). Then, in a second instance, the unique circuit identity is used to relay to the second network an address of the first subscriber terminal (68). By recognising that two connection requests have been received at opposite ends of the same phantom trunk, a processor in the second network is able to determine that a direct connection between the first and second subscriber terminals is required through the broadband network (48).

摘要: A non-geostationary satellite network incorporates a plurality of satellite nodes and ground stations in communication with the nodes. Routing and control are established from a virtual model of the network. Within the virtual model, a capacity of space segment band width for different traffic QoS classes can be determined. The relationship between the virtual model and the real network is used to transfer the capacity determination to the real network.

摘要: An open Services architecture for inter working narrow band services with equivalent broad band services delivers services on both the existing narrow band network and a future broad band network based on flexible signalling connections. The architecture incorporates an adaptive grooming router providing a fully interconnected backbone network function providing connectivity between a plurality of multimedia access routers and a narrow band network. The multimedia access routers provide hub points where access units terminating ISDN basic access and primary rate access lines used for multimedia services are terminated.

摘要: In a broadband network comprising a plurality of edge switches interconnected by a plurality of tandem switches, IP packet data is routed by determining from each packet whether that packet forms part of a flow of packets. Where a packet is determined to be part of a flow, it is segmented into minicells for transmission over a permanent virtual channel established across the network for that flow. Where a packet is not determined to be part of a flow, a destination edge switch is identified for that packet which is then transported to that edge switch via a default permanent virtual channel. Permanent virtual channels for new flows are established at the network periphery by defining a succession of nodes and virtual channels (VCs) to be used to reach the destination of that flow.

摘要: In an ATM network a flexible AAL1 processor is connected to a similar AAL1 processor by a virtual circuit. This virtual circuit has nx64kb/s capacity wherein each 64kb/s channel or a Px64kb/s subset of the capacity can be used for a separate call. The virtual circuit behaves similarly to trunk groups within present day digital networks and it is therefore termed a Virtual Trunk Group. Many Virtual Trunk Groups can be connected between the same two endpoints and contained within a virtual path thus forming a Virtual Route. The network is provided with a mechanism which allows the nx64kb/s capacity to be changed by a managed process which ensures that established calls are not affected by the change of capacity. This change of capacity is performed in such a way that the clock systems of the two AAL1 processors are able to behave in the normal manner for synchronised or plesiochronous switching networks without incurring additional frame slips in the AAL1 data stream. Frame slips due to the behaviour of the clock systems are still processed in the normal manner.
