Abstract

Data centers serve as the backbone of modern computing infrastructures, handling vast amounts of data and facilitating seamless communication between numerous interconnected devices. To meet the escalating requirements of these data-intensive environments, the design and optimization of network components, such as switches, play a pivotal role. This paper addresses the specific challenges encountered in data centers and aims to contribute to the ongoing efforts to enhance network performance, reliability, and efficiency. One critical component under scrutiny is the optical switch, a key element in the architecture of data center networks. This paper presents a comprehensive study on the design and performance analysis of a feed-backward and re-circulating type buffer-based optical switch tailored for next-generation networks. The investigation focuses on a scenario where N = m = K = 16, and D = 1, eliminating the need for splitter and combiner components in the buffer. The switch exclusively employs a feedback buffer with single packet storage, allowing for a maximum re-circulation of 16. The analysis reveals a high Packet Loss Probability (PLP) at a load of 0.7, with notable improvements achieved by increasing the buffer depth to D = 4.
