Some Issues on Computer Networks: Architecture and Key Technologies

The evolution of computer networks hasexperienced several major steps, and research focus of each step hasbeen kept changing and evolving, from ARPANET to OSI/RM, then HSN (highspeed network) and HPN (high performance network). During theevolution, computer networks represented by Internet have made greatprogress and gained unprecedented success. However, with the appearanceand intensification of tussle, along with the three difficult problems(service customizing, resource control and user management) of modernnetwork, it is found that traditional Internet and its architecture nolonger meet the requirements of next generation network. Therefore, itis the next generation network that current Internet must evolve to.With the mindset of achieving valuable guidance for research on nextgeneration network, this paper firstly analyzes some dilemmas facingcurrent Internet and its architecture, and then surveys some recentinfluential research work and progresses in computer networks andrelated areas, including new generation network architecture, networkresource control technologies, network management and security,distributed computing and middleware, wireless/mobile network, newgeneration network services and applications, and foundational theorieson network modeling. Finally, this paper concludes that within theresearch on next generation network, more attention should be paid tothe high availability network and corresponding architecture, keytheories and supporting technologies.
