Abstract :
Summary form only given. The development situation of telecom services is firstly reviewed in this presentation. The evolution trends of network services with IP, broadband, streaming, P2P (peer to peer) and mobility features are described. The presentation introduces the evolution direction and prospect of networks technologies especially NGI (next generation Internet) and NGN (next generation network) as well as broadband mobile IP network. The presentation also gives a brief overview of representative projects within research activities on NGI including the CNGI (China´s next Internet demonstration project). Finally, the challenges that network development faced are discussed such as scalability, QoS, pervasive computing and ubiquitous networking, security issue and shortage of frequency spectrum as well as dilemma whether to do evolution or revolution strategy of network development.
