Everyday more content is added to the Internet and more people are trying to look at it. Already router interfaces have to reach as high as 100 Gbps, but in the future this just will not be enough. Researchers at NTT Network Innovation Laboratories in Japan will be demonstrating their SLICE network architecture, which is more efficient than current network designs and will hopefully lead to the 1 Tbps speeds needed in the future, at the Optical Fiber Communication Conference and Exhibition/National Fiber Optic Engineers Conference (OFC/NFOEC).
Modern optical network architectures are setup for worst-case scenarios, where every path gets a fixed bandwidth. In comparison, SLICE is elastic by design, so when one path needs more bandwidth, it will get it from those that do not. This is achieved by using multi-flow optical transponders and elastic optical networking technology, so fewer router interfaces are needed. The entire design is to be more optically efficient while increasing network capacity.
