Metro Ethernet services are now being delivered over nation wide metro ethernet networks, which are switched layer 2 networks. Delivering IP control protocols like ARP and DHCP over these networks is a challenge. There are inherent scalability problems in the way these protocols use broadcast to discover the services. This paper presents a uniform and scalable architecture based on distributed directory for service, location and path discovery for all services (including IP control protocols like ARP & DHCP and IP Routing service) over Carriers' Metro Ethernet networks (MENs). It provides two methods of maintaining the Distributed Directory to ensure that a service can be discovered at the earliest and at the same time making sure that the Directory doesn't grow too big. It also proposes how IP networks can be overlaid and how IP Routing Service can be delivered over a single public MEN without using IP Routers and IP Routing Protocols. It is a novel, unified and comprehensive Service Delivery Architecture for delivering any service over a Carrier's MEN.
