Tiivistelmä
The thesis concentrates on Metro Ethernet and Carrier Ethernet solutions in Service Provider and Access Provider networks. Ethernet has been in use in local area networks for more than 30 years. The success of Ethernet is based on its simplicity, ease of deployment, versatility, and low cost. Until the end of the 1900s Ethernet technologies were mainly restricted to LANs, but there were efforts to move from the mainstream LAN technology to metropolitan area network solutions.
The next step in the evolution was to use Ethernet techniques in metropolitan area networks in the beginning of the 2000s. The Metropolitan Ethernet (Metro Ethernet) networks based on previous Ethernet standards are deployed in a metropolitan area. The successor of the Metropolitan Ethernet is Carrier Ethernet. It uses high-bandwidth Ethernet technology to create Internet access and communication between local area networks. Metro Ethernet and Carrier Ethernet can also be used to connect physically multiple locations to a network via an Ethernet Private Line. The driving force in the evolution is a vast increase of sites requiring fast and flexible services. Advantages of these implementations are lower cost of equipment and compatibility with customers’ equipment, that are based on Ethernet techniques.
In this project the underlying telecommunications background, including protocols and conventions, is described shortly. Metro Ethernet and Carrier Ethernet technologies are represented in detail, and two real-world cases are introduced, the emphasis being in Access Providers networks. The solutions are compared with legacy implementations, and benefits and limitations are discussed.
