The article features the edge quadrature amplitude modulation (QAM). As described, edge QAM is built to carry both video on demand (VOD) and switched digital video streams. It is considered a network resource because it can talk to at least two other devices; the session manager, which sets up the linkage between the company and the VOD user, and the resource manager, which figures out which QAMs are supposed to be moving what stuff to where.
