Abstract: A method to assign upstream timeslots and codes to a network terminal in a point to multipoint communications network includes assigning at least one code to the network terminal for inclusion within a network terminal grant assigning upstream timeslots to the network terminal. A medium access controller performs the method for assigning upstream timeslots and codes. The network terminal is adapted to extract codes from the network terminal grant, and to encode upstream data packets with codes before the upstream transmission of the encoded data packets, upon receipt of this network terminal grant.

Abstract: A method to assign upstream timeslots and codes to a network terminal in a point to multipoint communications network includes a step of assigning at least one code to said network terminal for inclusion within a network terminal grant assigning upstream timeslots to said network terminal. A medium access controller for performing said method is as well described. The network terminal is adapted to extract said at least one code from said network terminal grant, and to encode upstream data packets with said at least one code before upstream transmission of the encoded data packets, upon receipt of this network terminal grant.

Abstract: The invention relates to a bandwidth broker (34, 36) for a domain (30, 32) of a telecommunication system comprising a plurality of domains, said bandwidth broker being associated with at least one border router (40, 50) of the corresponding domain in such a way that it can obtain information about the routing tables of this border router in order to be able to allocate resources to data routes inside the domain and outside the domain.

Abstract: The present invention relates to the ability to set up connections on demand between subscribers and service providers and allows network capacity to be best shared among users. Whenever a service terminal (ST) requests a service (S) from a service provider (SP), an authentication server (AUTH) checks whether the service terminal can access the requested service. If so, a network controller (CTRL) set up a connection (C) to deliver the requested service with the required quality of service, said connection being established between the network termination (NT), to which the service terminal is coupled, and the access server (AS), to which the service provider is coupled. The authentication server supplies transport requirements of the requested service for establishing the connection.

Abstract: A telecommunication system to interconnect end-users and comprising one or more interconnected Virtual Service Networks (VSN) each associated to a data transport network. Each Virtual Service Network provides Quality-of-Service (QoS) guarantee for aggregated dataflows and comprises a Virtual Service Network Controller (VSNC) to control the resources of the Virtual Service Network and to perform a per-user admission control on each dataflow wanting to be transferred through said associated data transport network. Furthermore, each Virtual Service Network has a reachability agreement providing Quality-of-Service guarantees between endusers of the telecommunication system.
