Abstract

L'invention concerne un système et un procédé de concaténation de VT1,5s et STS-1S, sur un réseau optique synchrone (SONET), sur un réseau hiérarchique numérique synchrone et sur un réseau à multiplexage de longueurs d'ondes. Dans un mode de réalisation, le système et le procédé consistent (1) à créer un canal nxSTS-1 virtuellement concaténé, (2) à former, dans ce canal nxSTS-1, un ou plusieurs canaux nxVT à partir des VT, et (3) à faire correspondre une application à un canal nxVT ou à un canal nxSTS-1, d'après un accord de niveau de service. Dans ce système et ce procédé, la création consiste (a) à achever l'encadrement du réseau SONET, (b) à traiter des pointeurs, et (c) à compenser le retard, de manière à aligner STS-1s dans le canal nxSTS-1 virtuellement concaténé, et la formation consiste (a) à traiter le surdébit VT des VT et (b) à faire correspondre le trafic aux canaux nxVT ou aux canaux nxSTS-1 en fonction d'une identification de connexion.
