Abstract

With a tremendous growth in the Internet traffic, next generation network have been requiring a large increase in transmission capacity, switching-system high-throughput and high-performance optical networking. Wavelength Division Multiplexing (WDM) technology has been increased to the number of wavelengths per fiber hundreds or more with each wavelength operating at the rates of 10Gbps or higher. Thus, the use of all-optical (photonic) networks based on the WDM technology is considered promising to provide peta-bit bandwidth for next generation Internet. To enable the future peta-bit photonic 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.
