According to the feedback shared buffer structure, the simulation results of the distribution of optical buffer loss with different delay granularity in the traditional continuous distributed optical buffer structure are studied. In the traditional continuous distributed optical buffer architecture, the packet loss mainly occurs on the small-sized optical buffer. Therefore, it is proposed to reduce the packet loss rate by appropriately increasing the small-size optical buffer, and the simulation results show that The optical buffering scheme can significantly reduce the node’s packet loss rate
