Ethernet can be used to connect twisted copper pair networks and to connect fiber optic cable networks.
MPLS is a standardized data switching technology that optimizes network traffic flow and eases management of data networks. MPLS carves specific paths data packets that are identified by a label that saves the time needed for a router to look up the address to the next node in order to forward the packet. MPLS works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay network protocols. MPLS allows most packets to be forwarded at the layer 2 (switching) level rather than at the layer 3 (routing) level and makes it easy to manage quality of service (QoS).
A major feature of Internet over Ethernet is the ease in which you can upgrade from 1 Mbps to 1 Gbps. Simply call your Internet Service Provider (ISP) and ask for an upgrade and it can be provisioned almost in real time. This service is the future of Internet access for the foreseable future.
Digital Subscriber Line (DSL) connects end users (subscribers) to the Internet via a plain old telephone service (POTS) line that uses an existing copper pair but has been sped up by a Digital Subscriber Line Access Multiplexer (DSLAM) located at the service provider centeral office (CO) to form a continuous digital high-speed data connection from the customer premise to the Internet.
Exlpore why Ethernet is probably the next killer broadband delivery platform.
