Abstract:
A data-centered structure telecommunications network, comprising:an Internet protocol (IP) layer; a transport layer; and a management interface; wherein the IP layer controls the transport layer through the management interface by, determining the activation or the release of lines according to the transport requirements of the IP layer; wherein said management interface comprises client functions (CLI), residing in the IP layer, and server functions (SER), residing in the transport layer, exchanging messages with each other; wherein said client functions (CLI) comprise: a resource inventory function: it collects information from the transport layer relating to the availability of communication resources which could be used by the IP layer; a performance monitoring function: it collects information from the transport layer in order to check whether the desired service quality is achieved by the transport layer itself; a fault management function: it requests alarm information from the transport layer; a connection management function: it requests the transport layer to establish a traffic connection configuration or the release of traffic connections when these are no longer necessary; wherein said server functions (SER) comprise: a performance monitoring function: it reports information from the transport layer about the network resources which are available for the IP layer; a fault management function: it processes alarm information from the transport layer which should be reported to the IP layer; connection management function: it carries out the requests from the IP layer to establish the traffic connection configurations or to release traffic connections when these are no longer requested by the IP layer.
