在未来高性能光交换网络的设计中，多播能力和串扰问题需要慎重考虑。本文主要研究基于榕树结构和定向耦合器技术的光交换网络。我们探讨这些网络的能力，以支持一般的f-cast流量，其中包括单播流量（f = 1）和组播流量（f = N）的特殊情况下，并确定这些网络的条件下，严格的f-cast非阻塞各种串扰的限制。特别是，我们提出了一个优化框架，以确定非阻塞条件时，一般的串扰约束的f-cast光子网络。
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.
