| PBT and Metro Network Transport Analysis |
| New report discusses drivers for Carrier Ethernet transport; Provider Backbone Transport (PBT) technology, functions and misconceptions; cumulative answers to the service provider survey; and recommendations to service providers, vendors and equity analysts. |
| Service providers currently face enormous competition in the telecommunication arena. Multiservice operators (MSO) continue to siphon a significant amount of voice and data revenue by offering bundled services such as VoIP, high-speed Internet, broadcast TV and VoD to consumers. Additionally, competitive local exchange carriers (CLECs) have aggressively pursued the market by delivering a periphery of metro Ethernet services with faster deployment cycles, ranging from E-LINE to E-LAN. These services are offered at very aggressive, competitive prices. |
| Now that traditional enterprise
Ethernet switches have transformed into carrier grade, service providers are transitioning from the customer premises equipment (CPE) to the core. The result: service providers are expanding their revenue markets while simultaneously reducing costs and increasing profit margins. |
| Although carrier Ethernet (CE) has become the technology of choice, some challenges still remain: maintaining resiliency and scalability without compromising service level agreements or the quality of experience to which customers are accustomed in Legacy systems, such as TDM, frame relay, ATM, and SONET/SDH. |
| Carriers that attempted to implement native Ethernet switching discovered that it was adequate for high-speed Internet or campus networks services. However, as service levels expanded they realized that they needed a true carrier Ethernet switch to support Legacy applications. Ethernet over SONET/SDH is great for a vendor that services a large SONET/SDH market, but it is a Band-Aid approach to improving the economics of carrier Ethernet in the transport. carrier Ethernet must incorporate similar characteristics of MPLS: traffic engineering, service OAM, 50ms resiliency, bandwidth guarantees and scale-to unlimited services while reducing the overall OpEx and CapEx. As a result of this demand, there has been a variety of options on how to design the metro with current synergistic MPLS technologies; these options include VPLS, H-VPLS, PWE3, RSVP-TE, and MPLS-TE. |
| But, the real and sometimes heated debate focuses on a Tier 1 carrier whose goal is to implement PBB-TE (formerly known as PBT) for the metro transport technology. Other carriers, six worldwide, are currently evaluating PBT in conjunction with PBB as other methods of transport processing via Ethernet private lines, Ethernet virtual private networks, and Ethernet virtual private LANs. These carriers question the feasibility of this new Ethernet transport technology to lower the overall cost while still offering
efficient service. |
