In DAF, per-flow admission control and resource reservation, in conjunction with a new IPv6 flow label mechanism, can be performed instantaneously in a fully distributed and independent fashion at the edge of network without hop-by-hop signaling. The flow label helps in resource reservation and packets forwarding for aggregated traffic on an edge-to-edge path basis. In addition, a bounded directional probing technique for DAF was designed to reconfigure resource reservation adaptively between every pair of edge router for aggregated traffic according to the fluctuation of its traffic load. The simulation results show that DAF provides QoS guarantees to individual flows with minimal overhead, as well as keeping the scalability characteristic like DiffServ.展开更多

This new kind of file morphology could exercise a long-term saving of file resources and efficiently utilize it. File management is the most important part of university information management. However, as various universities are different in their specific practice, file digital construction is different in construction manner and content.展开更多

The computer network is to interconnect the world dispersed and independent computers in accordance with the network protocol. With the rapid development of information technology at home and abroad, the developed countries or parts of the developing countries are strengthening their national information infrastructure. Several of gold projects in information technology as the representative is gradually go deeper, forming an unprecedented development in the entire information network technology. With the globalization of the construction market and intensifying of the competition, construction management requires the higher information technology, which is relatively backward in China＇ s construction industry. So it has important practical significance to clearly recognize the entire network computing model and technology developments, and properly apply to the construction project management.展开更多
