This paper presents the Time Shared Optical Network (TSON) as metro mesh network architecture for guaranteed, statistically-multiplexed services. TSON proposes a flexible and tunable time-wavelength assignment along with one-way tree-based reservation and node architecture. It delivers guaranteed sub-wavelength and multi-granular network services without wavelength conversion, time-slice interchange and optical buffering. Simulation results demonstrate high network utilization, fast service delivery, and low end-to-end delay on a contention-free sub-wavelength optical transport network. In addition, implementation complexity in terms of Layer 2 aggregation, grooming and optical switching has been evaluated.
本文提出了时分共享光网络（TSON），作为一种用于保证的、统计复用服务的城域网状网络架构。TSON提出了一种灵活且可调谐的时间波长分配方式，以及基于单向树的预留和节点架构。它无需波长转换、时间片交换和光缓存即可提供有保证的子波长和多粒度网络服务。仿真结果表明，在无竞争的子波长光传输网络上，网络利用率高、服务交付快且端到端延迟低。此外，还评估了在二层聚合、梳理和光交换方面的实现复杂度。
