Optical packet and circuit integrated (OPCI) networks provide both optical packet switching (OPS) and optical circuit switching (OCS) links on the same physical infrastructure using a wavelength multiplexing technique in order to deal with best-effort services and quality-guaranteed services. To immediately respond to changes in user demand for OPS and OCS links, OPCI networks should dynamically adjust the amount of wavelength resources for each link. We propose a resource-adjustable hybrid optical packet/circuit switch and transponder. We also verify that distributed control of resource adjustments can be applied to the OPCI ring network testbed we developed. In cooperation with the resource adjustment mechanism and the hybrid switch and transponder, we demonstrate that automatically allocating a shared resource and moving the wavelength resource boundary between OPS and OCS links can be successfully executed, depending on the number of optical paths in use.
光分组与电路集成（OPCI）网络利用波长复用技术在同一物理基础设施上同时提供光分组交换（OPS）和光电路交换（OCS）链路，以处理尽力而为服务和质量保证服务。为了立即响应OPS和OCS链路的用户需求变化，OPCI网络应动态调整每条链路的波长资源量。我们提出了一种资源可调整的混合光分组/电路交换机和转发器。我们还验证了资源调整的分布式控制可以应用于我们开发的OPCI环形网络测试平台。与资源调整机制以及混合交换机和转发器协作，我们证明了根据使用的光路数量，可以成功执行自动分配共享资源以及移动OPS和OCS链路之间的波长资源边界。
