The traffic increase forces the use of high port count WSSs to create large scale OXCs, however, it will be very difficult to substantially increase the WSS port count, for example ten times. To resolve this issue, we have developed various technologies. We have clarified the role of inter- and intra-node blocking in the creation of bandwidth abundant networks utilizing such OXCs. We conducted thorough investigations to identify the best arrangement that matches the envisaged requirements. The different OXC architectures that exploit intra-node blocking includes are invented. It is shown that by properly introducing a slight limitation on routing performance and by applying the contention-aware RWA algorithm, the required hardware scale can be significantly reduced while the performance offset can be marginal. As a result we succeeded in developing very large scale and cost effective OXCs.

流量的增加迫使使用高端口数的WSS来创建大规模的occ，然而，大幅度增加WSS端口数（例如10倍）将非常困难。为了解决这个问题，我们开发了各种技术。我们已经阐明了节点间和节点内阻塞在利用这种occ创建带宽丰富的网络中的作用。我们进行了彻底的调查，以确定符合预期要求的最佳安排。发明了利用节点内阻塞包含的不同的OXC架构。结果表明，通过适当地引入对路由性能的轻微限制和应用竞争感知RWA算法，可以显着减少所需的硬件规模，而性能偏移可以是微不足道的。因此，我们成功地开发了非常大规模和具有成本效益的oxc。
