    Hitachi Review Vol. 55 (Dec. 2006) 167 Future Information-communication Technology in China Hui Deng OVERVIEW: Together with having the most populous, fastest-growing major Osamu Takada economy in world history, China will come to dominate the new “ubiquitous technology” market that is growing with the coming of the “ubiquitous- Shigeru Miyake information-network society.” In such a situation, Hitachi (China) Research & Development Corporation (HCR&D) has started research related to information-communication technologies such as mobile, broadband network, network management, and optical access—whose markets are led by China. HCR&D has also launched several collaborations with Chinese universities, research institutes, and telecom R&D centers to support those directions to exploit this research. INTRODUCTION IEEE) convergence is becoming more and more BY the end of 2005, the number of telephone promising in China (see Fig. 1). People at home or subscribers in China had risen to about 700 million. working in enterprises use various kinds of terminals Among them are 400 billion mobile-phone users and 300 billion fixed phones. Meanwhile, second only to the USA, China boasts the No. 2 position in the world in terms of both Internet users and broadband Internet Whenever, Cheap, Joyful, subscribers. At its current growth rate of over 90% wherever, safe, colorful, and whoever and efficient fashionable life per year, China will surpass the USA in total broadband subscribers by late 2006 to become the largest broadband country in the world. QoS Network Accompanying this rapid growth in the broadband Multicast management market, competition in China’s telecommunication market is becoming more severe.

The campus network users have many kinds of types, and the network resource they access to is not certain. In order to improve the flexibility of the different needs for campus network users to access external resources, so campus network access multiple ISP network. This paper based on the multi-export campus network environment, according to analyze the characteristics of campus network users, network access requirement of the campus network and the network export resources, put forward the user and resource management platform by using proxy technology, policy base routing and NAT technology, and studies the manageability, security and reliability of the platform. The construction schemes of the platform provides a reference for other campus network. Introduction With the continuous development of the Internet, the major companies and universities gradually began to establish their own internal network. The internal network began to access multiple ISP [1]. The speed of access to resource which is very fast in same ISP, but the speed is greatly reduced by cross ISP access.

  • Research of Multi-Export Campus Network Upgrade Program Based on Redundant Architecture
    2nd International Conference on Teaching and Computational Science (ICTCS 2014) Research of Multi-export Campus Network Upgrade Program Based on Redundant Architecture Shan Jing Na Yang Shandong Provincial Key Laboratory of Network Based School of Information Science and Engineering Intelligent Computing University of Jinan University of Jinan ,Jinan, China Jinan, China Email: [email protected] Email: [email protected] Qi Qi Runyuan Sun School of Information Science and Engineering Shandong Provincial Key Laboratory of Network Based University of Jinan Intelligent Computing Jinan, China University of Jinan, Jinan, China Email: [email protected] Email: [email protected] Corresponding author Abstract—In order to improve the stability and effectiveness university information system and the growth of the campus when campus network user access to Internet, the paper, relied network utilization, there is higher demand for effectiveness on the multi-export campus network environment and based and stability of campus network. on the analysis on characteristics and demands of the campus University of Jinan campus network was founded in 1996 network users, completes the design of network upgrade that is the first one to officially have access to CERNET in program by adopting the proxy, firewall, routing policy and Shandong Province, now has hundreds of information policy based routing. And it demonstrates the feasibility of the service platform. University of Jinan campus network has program by combining with application deployment in three IPv4 network exports: CERNET, China Unicom and University of Jinan. China Telecom. CERNET and China Unicom, the main Keywords: campus network; redundancy; multi-export; export links of campus network, each has an export proxy; firewall; policy based routing bandwidth up to 1Gbps.And China Telecom as an alternative export link of the campus network has an export bandwidth up to 100Mbps.
