摘要：
Due to the explosive growth in internet traffic, servers are facing bottleneck in speed and bandwidth requirements. To meet these ever increasing demands fiber optic technology can be used. This paper discusses, a hybrid buffer based optical packet switch design with its pros and cons. This hybrid buffer offers both electronic and optical buffering. This paper investigates the packet loss rate (PLR) performance of hybrid buffer under variety of conditions. The usage of buffer under different loading conditions has discussed. The sharing of electronic and optical buffers with respect to arrival of traffic is simulated, and delay ratio of electronic to optical buffering is computed. Average energy consumption at various loading condition is evaluated. The performance of switch is also investigated in a hypothetical five nodes network, and PLR is obtained under four different combinations of buffering and deflection of contending packets. © 2018 Walter de Gruyter GmbH, Berlin/Boston 2018.
