References 9 Introduction Metro E is also know as Metropolitan-area Ethernet, Ethernet MAN or metro Ethernet. It is a network that use in the metropolitan area and it is based on the Ethernet standards. This services is commonly used to connect user or network to a larger service or the internet. The user that own a business can use this system to connect they office to one and another. The user commonly use this system because it is cheaper than SONET/SDH(Synchronous Digital Hierarchy) or PDH (Plesiochronous Digital Hierarchy) that have an interface of the same bandwidth. SONET/SDH is known as a standard protocol that transfer a multiple digital bit streams over optical fibre using a laser or highly coherent light. PDH is a technology use in telecommunication network to transport a large quantity of that also use optical fibre and also microwave radio system. The Technology Application Metro E is commonly use in metropolitan city. It being use for businessman to connect their office to one and another. Many Ethernet services allow the user to network their business in ways that either more complex or impossible with the alternative services. As an example , a single Ethernet service interface can connect multiple enterprise location for their Intranet VPNs , connect business partner or suppliers via Extranet VPNs and provide a high speed Internet connection to an Internet Service Provider. When use this Ethernet subscribe, user will be able to add or change bandwidth using the other access network service within... ... commonly use for the large business. It is use to connect the business people with other branch, connect business people with their customer. It is use widely in overseas for their business. The Metro E that can transmit large data that make it being use for large company. It will transmit large data in a less amount of time. It will less the time for the company to develop and the business will have the benefits as the amount to buy it is less. Metro E is a easy application as it is wireless and can carry everywhere at anytime. It also can be use to use that just connect to each other.
