We present a measurement based resource allocation scheme for interconnected WDM rings in a metropolitan area network named DAVID (Data And Voice Integration over D-WDM). The network has a two level hierarchical structure, with a backbone of optical packet routers interconnected in a mesh, and metropolitan areas served by sets of optical rings connected to the backbone through devices called Hubs. The paper focuses on the operations of the media access protocol and on resource allocation schemes to be used in the metropolitan area network. A simple scheme for datagram (not-guaranteed) traffic is defined and its performance are examined mainly by simulation.
