Carrier Ethernet services is frequently the best selection to meet the requirement of the customers who want more bandwidth and better service quality to meet their application needs. Microwave technology is increasingly used to provide Carrier Ethernet. The main advantages of Microwave based Ethernet solutions are: - Rapid deployment time - Cost effective when compared to other approaches - Offers throughput that rivals fiber for many applications - Mature carrier-grade solution The interfaces are inexpensive, standardized and enables subscribers to add bandwidth incrementally, if needed. Ethernet services offer a flexible method for enterprises and individuals to connect remote offices, suppliers and business partners with the QoS and reliability their applications require. All communication equipment in the telecommunication network supports some network functions. The elements can be configured to support data transmission channels. These channels allow the information to be switched and transmitted from one part of the network to any other part of the network. Again, the management capabilities are required to ensure that this information transmission is conducted in a controlled way, with a measurable quality, error detection and repair capability. In addition, the statistics of various kinds relating to the information transfer need to be collected, correlated, and reported to various entities such as operation control, monitoring, and administration systems. The telecommunication network must be able to provide services to the end customers, such as Data services or information services. These services are supported by the networks and their elements. Again, some operation systems are required to support different aspects of provision of services. The services have to be delivered and activated; any service faults and customer problems have to be detected, located, and resolved. The services have to be operating with a reasonable and measurable quality and the services have to be billable and paid for by the customers; therefore the accounting systems have to be deployed to generate bills for the network resource usage and any value-added service components. This requires all managements layer to do corporative work, starting from elements layer which collects all statistical data that used to calculate the overall network usage ending with service layer which generates the bills to the customers
