Topics in integrated circuits for communications

In the past 10 years, we have witnessed a rapid paradigm shift in computing from that of mainframe to clientserver. This paradigm shift has enabled the realization of cloud computing where data and computing resources are no longer located at the client side but are readily accessible in a remote data center via the Internet. To support cloud computing for a large population of Internet users, data centers must support enormous aggregate bandwidth on the order of hundreds of terabits per second. The required bandwidth will continue to rise due to increased broadband Internet users as attested by the more than 80 million in the United States alone as of 2010. By 2013, cloud computing is projected to increase by 300 percent.
