在未来的高性能光交换网络的设计中，需要认真考虑组播能力和串扰问题。本文重点研究了基于榕树体系结构和定向耦合器技术构建的光交换网络。我们探讨了这些网络支持一般f-cast业务的能力，其中包括单播业务(f=1)和多播业务(f=N)作为特例，并确定了在各种串扰约束下这些网络严格无阻塞的条件。特别地，我们提出了一个优化框架来确定在施加一般串扰约束时f-cast光子网络的无阻塞条件。
The multicast capability and crosstalk issue need to be deliberately considered in the design of future high performance photonic switching networks. In this paper, we focus on the photonic switching networks built on the banyan-based architecture and directional coupler technology. We explore the capability of these networks to support general f-cast traffic, which covers the unicast traffic (f = 1) and multicast traffic (f = N) as special cases, and determine the conditions for these networks to be f-cast strictly nonblocking under various crosstalk constraints. In particular, we propose an optimization framework to determine the nonblocking condition of an f-cast photonic network when a general crosstalk constraint is imposed.
