Abstract: The present invention is based on the use of surface adsorption to capture CO2 molecules from air, without requiring the need for bulk absorption within the bulk of the sorbent. Since surface adsorption is a much faster process than bulk absorption, the present invention offers a greatly increased CO2 capture rate, as well as a greatly improved energy efficiency, over conventional systems. The invention involves the use of a molecular monolayer of CO2 sorbent, a process and a system for capturing CO2 from air employing such a molecular monolayer of CO2 sorbent.

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.
