OPTIMIZED OPTICAL TRANSPORT
OF BUSINESS ETHERNET SERVICES

The move to Ethernet has come a long ways in reducing the overall cost of infrastructure, particularly when delivering business Ethernet service to customers. as an industry, however, we have now entered the second phase of the migration to Ethernet. In the first phase we achieved significant growth and savings through the introduction of Ethernet services. in the next phase we will find ways to more cost effectively deliver Ethernet as a native service and in conjunction with other service types. as popular as Ethernet is, service providers still need to deliver native TDM service and TDM traffic for backhauling other applications that have not fully migrated to Ethernet (legacy digital loop carriers, DSLAMs, and Cell tower's that still use ATM for instance).

So, where do we start ? How about at the optical layer ?
