“…In very recent work, Wang and co-workers also investigated hybrid optical switch where both electronic and optical buffer is used for contention resolution [21]. They carry out simulation study in terms of packet loss rate while considering use of FDL and FDL dimensioning.…”

Optical packet switching has the potential to be used as next generation data transfer technology. This paper, introduces an Arrayed Waveguide Gratings (AWG) switch where hybrid buffer (electronic ? optical) is used for the buffering of contending packets. Power budget analysis has been carried out under various switch designs. Comparison of optical and electronic buffering is done in terms of power required for the correct operation of the switch. Energy consumption per bit is also evaluated for both optical and electronic buffers for various buffering time ranges from nano-seconds to milliseconds. In the switch analysis it has been found that, amplified switch requires five times less power, in comparison to un-amplified switch for correct operation. Energy consumption analysis reveals that for shorter duration storage, optical buffer would be a better choice.

“…This problem becomes significant at higher data rates because header processing speed might not be compatible with the higher data rates. The OPS for DCNs has been described recently in some studies [9][10][11][12][13][14][15][16][17][18]. The OPS can only be used with fast optical switching technologies that are now available [19,20,10,21].…”

In this paper, we consider the performance of TCP when used in data centre networks (DCNs) featuring optical burst switching (OBS) using two-way reservation. The two-way reservation is not suitable in wide-area OBS networks due to high bandwidthdelay product (BDP). The burst loss using traditional methods of one-way reservation can be mistakenly interpreted by the TCP layer as congestion instead of contention in OBS network, leading to serious degradation of the TCP performance. The reduced BDP in DCNs allows the use of two-way reservation that results in zero burst loss. The modelled architecture features fast optical switches in a single hop topology. We apply different workloads with various burst assembly parameters to evaluate the performance of TCP. Our results show significant improvement in TCP performance as compared to traditional methods of OBS as well as to a conventional electronic packet switching DCN.
