<p>Described is a SDH or SONET telecommunication network element (NE) provided with a plurality of interfaces (I1, I2, I3) for managing first SDH or SONET flows, comprising: a) a plurality of first layer ports (PS) for managing second SDH or SONET flows, wherein the ports (PS) are individually programmable as concerns the hierarchical structure of the managed flows, and b) a switching system (SS) coupled to the interfaces (I1,I2,I3) and to the ports (PS), in order to implement the switching of virtual containers between the SDH or SONET flows, wherein the switching system (SS) is programmable as far as the switching to be implemented is concerned. <IMAGE></p> |
