Explanation:
Metro Ethernet
Metro Ethernet uses well-known "Ethernet" to deliver low-cost and high-speed MAN/WAN
connectivity for organizations. Many service providers now offer Metro Ethernet solutions to deliver a wide
range of converged network services such as data, voice, and video on the same wire. Metro Ethernet
provides enterprise LAN type functionality out in the MAN and WAN. increasing the throughput available
for applications. Metro Ethernet bandwidths can range from 10Mbps to 1 Gbps. and even higher in some
cases, allowing for support for higher performance and increased QoS requirements. In contrast to the
rigid nature of traditional TDM provisioning, Metro Ethernet services are much easier to deploy and scale
due to the flexible bandwidth increments. Metro Ethernet technology is appealing to many customers
because they are already comfortable using Ethernet throughout their LAN environments.
