Research output: Contribution to journalArticleProfessional


Because of the emergence of new services, the requirements for metropolitan area networks (MANs) have increased and diversified. Consequently, they are harder to meet - at least with the existing SONET/SDH networks - and new solutions are needed. VTT Information Technology has been researching next-generation SONET/SDH (Synchronous Optical Network/Synchronous Digital Hierarchy) networks, which could meet the diverse requirements of MAN while util ising the existing SONET/SDH network infrastructure.
