Keyao Zhu,Hongyue Zhu,Biswanath Mukherjee: Traffic Grooming in Optical WDM Mesh Networks
Description
Optical networks based on wavelength-division multiplexing (WDM) tech- nology offer the promise to satisfy the bandwidth requirements of the Inter- net infrastructure, and provide a scalable solution to support the bandwidth needs of future applications in the local and wide areas. In a waveleng- routed network, an optical channel, referred to as a lightpath, is set up between two network nodes for communication. Using WDM technology, an optical fiber link can support multiple non-overlapping wavelength channels, each of which can be operated at the data rate of 10 Gbps or 40 Gbps today. On the other hand, only a fraction of customers are expected to have a need for such a high bandwidth. Due to the large cost of the optical backbone infrastruc- ture and enormous WDM channel capacity, connection requests with diverse low-speed bandwidth requirements need to be efficiently groomed onto hi- capacity wavelength channels. This book investigates the optimized design, provisioning, and performance analysis of traffic-groomable WDM networks, and proposes and evaluates new WDM network architectures. Organization of the Book Significant amount of research effort has been devoted to traffic grooming in SONET/WDM ring networks since the current telecom networks are mainly deployed in the form of ring topologies or interconnected rings. As the long-haul backbone networks are evolving to irregular mesh topologies, traffic grooming in optical WDM mesh networks becomes an extremely important and practical research topic for both industry and academia.
An indispensable and distinctive book that will help anyone who wants to write, write better, or have a clearer understanding of what it means for them to be writing, from widely admired writer and teacher Verlyn Klinkenborg.
When Mizuki is almost caught changing clothes, the school goes wild with rumors about a mysterious girl on campus! Can our heroine keep her secret, or will she be outed and separated from Sano? Meanwhile, the girls of Saint Blossom Girls' High School are caught up in the boys' romances...
John Gray is the bestselling author of such books as Straw Dogs and Al Qaeda and What it Means to be Modern which brought a mainstream readership to a man who was already one of the UK's most well respected thinkers and political theorists. Gray wrote Enlightenment's Wake in 1995 - six years after the fall of the Berlin Wall and six years before the terrorist attacks on the World Trade Center. Turning his back on neoliberalism at exactly the moment that its advocates were in their pomp, trumpeting 'the end of history' and the supposedly unstoppable spread of liberal values across the globe, Gray's was a lone voice of scepticism. The thinking he criticised here would lead ultimately to the invasion of Iraq. Today, its folly might seem obvious to all, but as this edition of Enlightenment's Wake shows, John Gray has been trying to warn us for some Traffic Grooming in Optical WDM Mesh Networks free epub fifteen years - the rest of us are only now catching up with him.
