To overcome such bottleneck in existing protocols and exploit the evolving characteristics of high speed networks, based on a highly parallel architecture, a high performance transport protocol (HTPNET) and its experimental system is introduced in this paper.

To counter low effective function and confusion phenomenon of road system in large cities of China the paper puts forward a kind of road net structure model called as “express net box” and analyzes this model of road net structure, the relation with structure of urban land for use and the basic characteristics of sustainable development network structure.

For unifying the standard of judgement of network speed between users and network manager, the article introduces a method and implement the system to indicate network speed by measuring the accessing speed to website.

At present,network speed is a serious bottleneck problem for multimedia instruction in network environment.
