Abstract

This paper proposes a new Metro Network Architecture based on two key technological pillars: the subwavelength optical switching technologies in the Data Plane (i.e. optical bursts and packets), and an enhanced GMPLS architecture in the Control Plane to extend network control to the subwavelengths, and ease the interworking of network and IT resources. The proposed architecture promises greater cost efficiency, lower resource consumption, improved reliability and lower latency, compared to current metro network architectures.
