Data centers are experiencing an exponential increase in the amount of network traffic that they have to sustain
due to cloud computing and several emerging web applications. To face this network load, large data centers are required with thousands of servers interconnected with high bandwidth switches. Current data center networks, based on electronic packet switches, consume excessive power to handle the increased communication bandwidth of emerging applications. Optical interconnects have gained attention recently as a promising solution offering high throughput, low latency and reduced energy consumption compared to current networks based on commodity switches. This paper presents a thorough survey on optical interconnects for next generation data center networks. Furthermore, the paper provides a qualitative categorization and comparison of the proposed schemes based on their main features such as connectivity and scalability. Finally, the paper discusses the cost and the power consumption of these schemes that are of primary importance in the future data center networks
INTRODUCTION
OVER the last few years, the exponential increase of the Internet traffic, mainly driven from emerging applications
like streaming video, social networking and cloud computing has created the need for more powerful data centers. The applications that are hosted in the data center servers(e.g. cloud computing applications, search engines, etc.) are data-intensive and require high interaction between the
servers in the data center [1]. This required interaction poses a significant challenge to the networking of the data centers creating the need for more efficient interconnection schemes with high bandwidth and reduced latency. The servers must experience low latency communication among each other, even if the data center continue to increase in size comprising thousand of servers
