A few years after we deploy a 40GbE (maybe) and then a 100GbE, we are going to need TbE to carry rapidly increasing trafﬁc on the new mobile, video and embedded Internet. Mobile just passed a billion new cell phones per year. Video is becoming the dominant trafﬁc on the Internet, and that is before high deﬁnition (HD) and mobile video become fully online. Additionally, there are totally new sources of trafﬁc, such as the 10 billion embedded microcontrollers now shipped every year, a tiny but increasing fraction of which is now being mesh networked with ZigBee/802.15.4. The Internet is expanding at rates unimaginable even 10 years ago, and with new applications and trafﬁc characteristics not envisioned at the start. Metcalfe will walk through a roadmap to TbE, factoring in trafﬁc drivers and volumes, key issues and tradeoffs, and the relative roles of packet and high-bandwidth optical circuit transport and switching. For example, will TbE simply hasten the routing of today’s Internet Protocol (IP) packets, or will some form of lambda switching be needed to carry time-critical volume ﬂows? WEDNESDAY, FEBRUARY 27 REED E. HUNDT Former FCC Chairman, USA The Coming Global Triumph of Communications and the Threat to American Standards of Living The rise of emerging economies, and especially China, will surely have a negative effect on the wages and career choice of millions of Americans. What is less clear is how those skilled in communications technologies can help Americans respond positively and effectively to the China challenge. As it happens, communications technologies are part of the problem — they aid job loss — and part of the solution — they greatly enhance the single biggest opportunity for Americans: leading the world in green technology. 4 OFCNFOEC 2008
