…Flexibility in product portfolio refers to the ability to position Ethernet solutions in multiple transport networks, including native Ethernet, SONET/SDH and OTN networks. Although the market for Ethernet-optimized systems remains fragmented, a select number of vendors are building the flexible, serviceaware…

…profitability in the face of heavy competition, service providers must replace or augment firstgeneration, standalone Ethernet switches and basic Ethernet-over-SONET/SDH solutions with a more scalable, manageable, and deterministic service architecture. Providers require a cost-effective, reliable metro packet…

…applications; robust service management; and greater scaleability than traditional Ethernet solutions. While many types of products - including Sonet/SDH multiservice provisioning platforms (MSPPs), Optical Ethernet platforms, routers, and Layer 2/3 Ethernet switches - can be used to deliver a variety…

…Of course, it makes no sense to transport in both formats over the metro network. It makes even less sense to add capacity to legacy ASI over SONET/SDH platforms that will eventually run out of steam. You need a more scalable solution to cost-effectively transport and replicate an ever-growing number…

…basic service revenues flat at best, providers need the flexibility and cost-effectiveness of a converged IP-based environment to create a wider variety of applications with more personalized experiences that garner both loyalty and higher margins. Challenges Current metro networks based on SONET/SDH…

…perceived as being a best effort protocol suited only for the LAN because current implementations lack the basic transport-layer qualities and capabilities that carriers are accustomed to from SONET/SDH today, including: · Reliability · Availability · Fast protection and restoration · Performance monitoring…

…transitioning circuit based SONET/SDH optical transport networks to efficient carrier Ethernet transport. During the long migration period, SONET/SDH will be an integral but diminishing component. WDM is the only technology today (and on the horizon) that can solve the basic traffic growth problem, and the…
