Next-generation SONET/SDH technologies have fielded much-improved service mapping and provisioning capabilities. These features provide many exciting avenues for developing new Ethernet services, and various Ethernet-over-SONET studies have already been done. However these efforts have primarily focused on provisioning point-to-point demands, i.e., private line type offerings. This paper considers the broader and more challenging case of provisioning multi-point-to-multi-point Ethernet LAN services over SONET/SDH and presents novel strategies for bus and tree overlays. Detailed simulation results are also presented along with directions for future work.
