A switch that is deterministic in nature has the ability to engineer service quality by precisely controlling technical parameters such as loss, latency and jitter. It's the architecture. Tenor's CSX is purpose built to deliver predictable service levels in a packet-based environment. Our determinism is uniquely achieved with a fully connected output buffered switching architecture enabling along sophisticated queuing and scheduling policies. Without this fundamental capability, a switch cannot deliver guaranteed classes of service in a packet-based environment.
Determinism is the key to convergence.
It allows service providers to deliver multiple sources of revenue on a common platform, thereby optimizing revenue per capital investment. Deterministic behavior enables multiple service levels on a common infrastructure that can be leveraged to establish a framework for differential pricing. We think in terms of 4 discrete service levels, which are a direct analog to the types of services sold in traditional overlay networks. The analog for this service class in an overlay environment is leased line. The analog for this service class in an overlay environment is ATM VBR-rt.
