Other Carrier Ethernet requirements??”One Service Provider??™s perspective
While the MEF has made considerable strides in the realm of identifying and refining
the Carrier Ethernet attributes, it is, of course, a work in progress. Emerging applications,
field experience, and new network constraints/requirements continually push the
boundary and need to be addressed if Carrier Ethernet is to dominate the market.
Here a brief overview of the requirements that Carrier Ethernet faces ??” or will face
shortly, is provided and is based on the experience and insights of one of the foremost
Carrier Ethernet Service Providers, Verizon27. That most of these requirements are already
being actively addressed (or at least being considered) by the MEF vividly demonstrates
the unprecedented participation??”and influence, of Service Providers in MEF.
27 Verizon identifies these requirements in the context of its four key drivers for Carrier Ethernet??”Business
Ethernet services, Broadband access, Residential video service transport, and wireless backhaul.
