The Internet is experiencing an exponential growth in bandwidth demand from large numbers of users in multimedia applications and scientific computing, as well as in academic communities and military. With the development of Wavelength Division Multiplexing (WDM) technology, the number of wavelengths per fiber has been increased to hundreds or more with each wavelength operating at the rates of 10Gbps or higher. Thus, the use of all-optical networks based on the WDM technology is considered promising to provide peta-bit bandwidth for next generation Internet. To enable the future peta-bit networks, deliberate studies are deserved for some key techniques, such as the ultra-high speed all-optical switching, high performance routing and wavelength assignment (RWA), efficient restoration and protection, etc. This paper provides you with the knowledge about dense WDM networks, high-speed optical switching architectures, high performance routing and wavelength assignment, efficient restoration, as well as prospective vision of future photonic Internet.
