Ethernet Transport and its Service Technology
To understand why Ethernet is a viable transport for the WAN, it’s important to note the various technology that surrounds and supports Ethernet.
 
Figure 1 shows Ethernet’s circle of technology. At the core, Ethernet is supported within fiber, copper, and even wireless media. In addition, bandwidth support for Ethernet can range [...]

By far, the most widely used networking technology in Wide Area Networks (WANs) is SONET/SDH. With the growth of Ethernet now into Metropolitan Area Networks (MANs) there is a growing need to interconnect Ethernet LANs and MANs to these prevalent SONET networks. With the advent of 10 Gigabit Ethernet, the commonality of line rates between [...]
