“…A universal BB implementation for both NGN and non-NGN domains has been proposed [10]. That concept extends the standardized RACF architecture to cover not only standard NGN resource (i.e., border gateway function (BGF) in transport networks) but also non-NGN resources (e.g., passive optical network (PON), MPLS, etc.).…”

Towards the future development of global ICT environments, roles of network federation will become increasingly important and complex. Functional gaps between standard network architectures, such as conventional IP-based networks, next generation networks, and future Internet, tends to be remarkable. Architectural migrations from conventional IP to next generation network and to future Internet are analyzed to identify the role and remaining issues of the network federation of different standardized architectures. Possible solutions to network federation are proposed to address migrations to the next generation network and future Internet.

“…Figure 2 shows the architecture for controlling access network resources according to the status of the bandwidth utilization and the profile of the users. The bandwidth control system consists of Network Resource Managers (NRMs) [7,8] and a User Information Manager (UIM). The NRM manages and controls network resources of each transport network area.…”

A novel method and its system design for controlling user's traffic in broadband access segments to enhance fairness among users are proposed and demonstrated. Recently, various new applications such as consumer generated media (e.g. YouTube) and peer-to-peer file sharing have been emerging in addition to the conventional applications such as E-mail and World Wide Web. Such novel applications have behaviors different from those of conventional applications in terms of traffic burstiness, and they tend to exhaust bandwidth for a certain period of time. Hence, there is a potential risk that the traffic of small numbers of specific users assumes bad influence on the traffic quality as well as on the experiences of other users. Such situation must be avoided from the standpoint of service fairness among the users. The proposed bandwidth control system utilizes QoS-related functions of existing heterogeneous access equipments, and provides a mechanism for maintaining bandwidth assignment based on each user's profile and history of usage. Control of the user traffic according to a bandwidth assignment policy is successfully demonstrated using a prototype system implemented in a testbed.
