Dynamic Bandwidth

A reconfigurable optical data center network is proposed, in which the optical bandwidth can be automatically reconfigured by reallocating time slots based on the real time traffic. Numerical investigations validate that the network performance of packet loss after reconfiguration decreases by 58.5%, and the end-to-end latency decreases by 63.8% with comparison to the network with rigid link interconnections, and thereby increasing the 9.4% of throughput at load of 0.8.

The internet now plays crucial roles such as streaming videos, social networking, managing large scientific data. There is a need for high-speed Internet. The volume of data handled by the data centers is increasing very rapidly. Hence, the need to handle data center traffic effectively becomes inevitable. At present, the government office network uses a data center network design based on Fat-Tree that employs high-end IP switches. Unfortunately, the resulting network performance has delays of more than 0.06 ms, throughput of about 500 kbps, and packet loss rate is 2. This research introduces BCube to re-design and improve network performance (i.e., delay, throughput, and packet loss). Through this research, we propose a new data center design in the government office that improves the network performance significantly, with delays less than 0.004 ms, throughput more than 515 kbps, and packet loss rate 0, two–three percent better compared to the Fat-Tree data center network design that contributes significantly to the data center operations in the government office and its overall business performance through the data center network design.
