Interface
cards and Ethernet switches are ubiquitous and offer very high capacity at a very
inexpensive cost per bit, resulting in Ethernet??™s near total domination of enterprise
and campus area networks. Enterprises now wish to interconnect multiple sites and
connect to the public Internet while maintaining the performance of their applications,
and Mid-Band Ethernet allows this.
For years now, many carriers have been replacing and phasing out their ATM and
SONET core infrastructure, migrating their customers to a less expensive, more reliable
Ethernet/IP/MPLS infrastructure. The access network is really the final frontier??”
the last mile is the final barrier to cross in the carrier evolution from TDM to packet
networking. Mid-Band Ethernet technologies erase that final barrier and permit a fully
integrated packet network.
Cost and Complexity of Deploying Fiber
The market demand for these next-generation services is being met by the implementation
of high capacity, metro area and/or intercity Ethernet services at attractive price points by
all major service providers. Core packet networks have been rapidly built, and intensive
capital spending programs have deployed fiber access to large buildings and major data
centers.
