Local-area network (LAN) bandwidth prices have plummeted in the past decade with the advent of Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet. Legacy MAN/WAN connectivity (such as DS1 and DS3) prices have not followed the same exponentially decreasing pricing trend. Customers want to leverage the cost advantages of Ethernet, while receiving a similar level of service that they currently have with their dedicated lines. Carriers can benefit from Ethernet deployments due to the simplicity and ubiquity of the interface ...
