The effects of network neutrality on the diffusion of new Internet application services

The debate over network neutrality started with the appearance of new Internet application services that are latency sensitive and the use of broad bandwidth. These services are still diffusing, and more applications that use broader bandwidth with greater latency sensitivity are expected to be developed. To estimate precisely the effect of network neutrality regulation, it is necessary to forecast the number of end-users that will adopt application services. However, previous studies are limited in that they assume that the potential market and the final number of adopters are constant at the current market penetration level. By computational experiments, this research estimates the effect of network neutrality regulation considering the diffusion process of application services such as IPTV and VoIP. Additionally, it deduces the relation between the effect of network neutrality regulation and the level of diffusion of new Internet application services.

Study on Service Level Management in Integrated Satellite Information Network

Integrated Satellite Information Network (ISIN) includes those nodes in space and those on ground. It is the way to realize the fusion of satellite communication and traditional network technology. A satellite network management system based on Multiplex Network Management Protocol (MNMP) has accomplished traditional management, such as configuration, performance and fault management. An architecture of Service Level Management (SLM) in ISIN is proposed, and a service topology management and Service Level Agreement (SLA) are deeply researched. At last, service security and fault management are briefly discussed, and a simulation system is accomplished.
