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 (also spelled Internet T-1) is a high-speed digitally transmitted connection to the Internet that transfers signals at 1.544 Mbps (1,544,000 bits per second) that can be divided into twenty-four 64 Kbps telephone lines or trunks.

Many VoIP service providers guarantee that phone calls will not travel over the public Internet, but are converted and transmitted over the traditional telephone network directly from the VoIP provider's private Internet network that usually adheres to a defined Quality of Service (QoS).

MPLS network is particularly important to businesses running applications that require latency such as VoIP, ERP, SAP, etc.

Internet access via Ethernet is becoming more and more popular to meet the growing demand for dynamic high bandwidth increases. For example, an increase from 10 to 100 Mbps can be accomplished by a High Speed Internet over Ethernet provider by simple changing the settings on already installed Ethernet switches. This scalability is cost effective for customers in that bandwidth can be increased or decreased quickly and easily, on demand, without the necessity of adding or changing datacom equipment as would be required with T1 / T3 or E1 / E3 local access lines.

DSL has become a widely-accepted and increasingly reliable method of delivering phone service and providing Internet access that saves end users money because both voice and data are delivered across the same plain old telephone serivce (POTS) line. However, the distance to the local phone company central office where the copper POTS line is connected from the customer premise to the DSLAM will determine the potential speed of the DSL connection.

Exlpore why Ethernet is probably the next killer broadband delivery platform.
