Comparison of different NGN aggregation networks scenarios

摘要

The possibilities of communications are rapidly changing. Providing the infrastructure to new production forms like distributed manufacturing or cloud robotics, IoT (Internet of Things) or M2M (Machine to Machine) becoming necessary for economic revitalization. With the development of Internet technology, as well as increasing the availability of the growing Internet users, live streaming services are face increasing challenges for service providers who wish to multimedia content and data transfer to as much as possible users. With the unification of services such as Internet, TV, telecommunications services, multimedia and video, live stream not only become desirable but necessary. The development of many new telecommunication services such as personals services, virtualized in - network - storage services, video services, High Definition (HD+) IPTV service and multiplication of user's terminals, leads to a significant increasing of bandwidth demands. All this high bandwidth new services could lead to traffic bottlenecks when the ratio of the capacity of output interface to the sum of all input links' capacities is not enough. Such bottlenecks could in turn lead to QoS degradations such as packet losses, excessive delay, and jitter degradation. Most usually bottleneck is settled somewhere inside access or aggregation networks.
