A draft ITU-T recommendation specifies smart traffic control and resource management functions for “smart ubiquitous networks” (SUN), a working document we obtained said. SUNs are IP-based packet networks that can provide transport and delivery of a wide range of existing…

and emerging services to people and things, it said. The networks are smart in the sense that they are knowledgeable, context-aware, adaptable, autonomous, programmable and can affect services effectively and securely, it said. Various smart user devices in fixed networks are demanding more traffic from emerging services such as smart TV, HDTV, 3D TV and video streaming, it said. Networks are required to allocate more resources to support more bandwidth and various service features such as real-time, non-real-time, store-forward and others, it said. These are some of the causes for the enormous rise in traffic, it said. A “few maniacs,” both users and providers, of services and applications “monopolize” almost all network resources, it said. This monopolization of network resources, both in terms of bandwidth and number of sessions, prevents proper network resource arrangements for use by everyone else, it said. The monopolization of resources degrades service quality and prevents further development of smart devices and their services, it said. Smart end user devices, such as smart phones, in wireless environments, including mobile, also use various broadband multimedia services, for example, Web TV, multimedia services including mobile networked games and video-phones, it said. The trend toward wireless services is causing traffic congestions, high bandwidth use, and a reduction in the number of users in mobile access networks, it said. Delivery to end user devices over mobile and wireless access is done with quite limited resources compared to fixed access, it said. Incoming traffic from fixed network environments to the mobile access environments should be coordinated and harmonized for better operation of mobile resources as well as to ensure, as much as possible, services to users, it said. Smart traffic control and network resource management should be carried out in transparent ways and by reasonable means to protect users’ quality of service and experience requirements against resource monopolization, it said. KT Corp. was reportedly a major contributor to the proposal. The recommendation is slated for ITU-T’s rapid approval process in February, which indicates no regulatory concerns have been raised.
