Research on Internet 3A Access Paradigm and Related Technologies
Internet 3A访问模式及相关技术的研究

With the developing and changing of computing patterns,the assessing technology of users also face new requirements. In networks with loosely-coupled and dynamic resources,an access mechanism characteristic of time-in- dependent, space-independent and physics-independent, which is called 3A(Anytime, Anywhere,and on Any device) access paradigm, should be provided for users. This paper analyzes the visions and requirements of 3A access paradigm and proposes three basic characters of the 3A paradigm,namely continuation,mobility and adaptability. Ad- ditionally we summarize and compare several solutions and relative technologies that support the three characters.
