Elastic optical network (EON) is considered as the platform for future optical transport networks. Routing and spectrum allocation (RSA) has a significant bearing on EON. Currently, researches tend to presume that RSA supports discrete or continuous rates. However, the approach of applying continues rates inevitably places a high burden on the management and implementation of EON. Contrastingly, discrete rates are static and could be misaligned with the demands of customers. We propose an EON that advertise continuous (any) rates, while in reality admitting a limited set of quantized levels. This approach redesigns the marketing strategy of EON services. We show how to quantize and map the continuous advertised rates into a limited set of quantized levels optimally, and with minimal effect. We use simulation to evaluate the different parameters impacting the continuous model and confirm the feasibility of the proposed model.

一种弹性光网络的持续服务模型

弹性光网络（EON）被认为是未来光传输网络的平台。路由和频谱分配 (RSA) 对 EON 具有重要影响。目前，研究倾向于假设 RSA 支持离散或连续速率。然而，采用连续费率的方法不可避免地给 EON 的管理和实施带来了沉重的负担。相比之下，离散费率是静态的，可能与客户的需求不一致。我们提出了一个 EON 来宣传连续（任何）速率，而实际上允许一组有限的量化级别。这种方法重新设计了 EON 服务的营销策略。我们展示了如何以最佳方式将连续广告速率量化和映射到一组有限的量化级别，并且效果最小。
