MPLS VPNs transport layer 2 packets across the network and encapsulate transport protocols such as ATM, Ethernet, and SONET, allowing MPLS networks to seemlessly upgrade and replace legacy layer 2 networks without requiring network reconfiguration or using protocols higher than layer 2. In comparison, layer 3 VPNs must use the layer 3 Internet Protocol (IP).

An Internet T1 (sometimes spelled T-1) is a high speed telecommunication line that can carry 24 digitalized voice channels, or it can carry data at a rate of 1.544 megabits per second.

Voice over IP is a digital phone service that allow users to make calls across the public switched telephone network (PSTN) via the Internet. By using a high speed Internet connection and a VoIP phone or analog telephone adapter (ATA), a user receives the same type of phone service as plain old telephone service (POTS) plus many additional features. For example, find me / follow me allow a user to enter all of the phone numbers the user wants to ring when the user's VoIP phone number is called. If you are at home, at the office, or on your mobile phone, all of your phones can be rung in succession or at the same time using VoIP!

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).

The wide-spread use of Ethernet has reduced the cost of Ethernet switches and also the space required to deploy Ethernet networks either via twisted pair copper or fiber and virtually all computer manufacturers include an Ethernet card as a standard component on Personal Computer (PC) motherboards which eliminates having to install an Ethernet card as a peripheral device.

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.

Telecom Links mission is to be a comprehensive source of telecommunications information on the World Wide Web.

Layer 2 MPLS VPNs (L2VPNs) are similar to Frame Relay, Asynchronous Transfer Mode, or point-to-point Wide Area Networks (WANs).
