Method and apparatus for obtaining a scalable and managed bandwidth for connections between asynchronous level and synchronous hierarchy level in a telecommunication network

摘要

The present invention provides for a method and apparatus for obtaining a scalable and managed bandwidth for connections between asynchronous and synchronous hierarchy level in a telecommunication network, in which the bandwidth of the synchronous hierarchy level is rendered scalable by a variable number of connections in a link between two nodes, each of the connections being made by a synchronous frame of lower-order virtual containers only (e.g. VC12 at 2 Mb/s in SDH). The incoming data packets are singularly and independently arranged in the VCs of the various connections, ensuring their integrity. The number of connections to be used is variable and scalable, and controlled depending on the total incoming packet data rate, so as also to ensure the minimum of necessary granularity.
