Next generation cable networks with DOCSIS 3.1 technology [Guest Editorial]

Modern cable networks are continuing to evolve at a rapid pace, driven by consumer demand for new interactive services. This is driving a convergence between traditional broadcast video and Internet video, as well as the need for higher capacity broadband networks. At the same time, Radio Frequency (RF) transmission technology has continued to evolve, offering the opportunity to utilize the resources of the cable network more efficiently and cost effectively. The needs of network evolution, combined with the opportunity of new technology, recently resulted in the development of a new version of DOCSIS® technology, the DOCSIS 3.1 specifications.
