Analysis of Hybrid Buffer Based Optical Data Center Switch
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 loss rate (PLR) performance of hybrid buffer packet 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.

摘要： We demonstrate error-free 100-Gb/s optical packet switching with low power consumption by using a combination of a label processor and 8 × 8 broadcast-and-select (B&S) optical switch. To achieve energy-ef?cient label processing, an optical-trigger-pulse generator that consumes energy only for a very short duration is realized, whereas the optoelectronic serial-to-parallel converter used to interface the fast label bits to a slow CMOS processor has been improved to operate with a reduced trigger pulse energy of 0.35 pJ. Moreover, the electro-absorption-modulator-based B&S optical switch is signi?cantly enhanced by introducing a surface ground electrode for eliminating electrical crosstalk and integrated spot-size converters with easy fabrication process. The total power consumption of the full 8 × 8 optical packet switch is estimated to be as low as 27.3 W or 3.4 W/100-Gb/s port.
