Carrier Ethernet is a ubiquitous, standardized, carrier-class Service and Network defined by five attributes – Quality of Service, Reliability, Scalability, Service Management, and Standardized Services. Carrier Ethernet brings the compelling business benefit of the Ethernet cost model to achieve significant savings and enables new distributed applications for enterprises and accelerates their deployment. Carrier Ethernet is increasingly used for implementing mobile backhaul networks, delivering Ethernet services for the enterprise and business user, as well as being deployed in the access, metro, and core networks. Carrier Ethernet is also being deployed to deliver mission critical applications in various verticals such as health care, finance, education, government, and media. As with any new technology, rapid adoption of Carrier Ethernet comes with its own set of unique challenges. Both providers and their customers are concerned about managing the service lifecycle effectively to reduce operational expenditures. They are also interested in understanding the performance of their Carrier Ethernet services so that they can segment the network and isolate troublesome spots easily. They would like to fix as many problems as possible without having to do a truck roll, as truck rolls tend to be expensive. Further, they are all interested in understanding the historical performance of their networks and services so that they can more effectively plan for the future. This includes knowledge of changing trends of network quality over many dimensions including time, regions, customers, partners etc.
