The traffic between geographically distributed data centers (DCs) becomes bandwidth hungry. Since the optical interconnection has a high capacity, the optical data center network (ODCN)—where DCs are located at the edge of the optical backbone—emerges. By virtualization, the virtual networks—representing service requirements—are embedded onto the same part of the substrate ODCN. Each virtual network has virtual machine (VM) nodes interconnected by virtual links (VLs). Therefore, a virtual… CONTINUE READING
