A Survey on New Architecture Design of Internet

The current Internet, which is based on TCP/IP architecture, exposed its inherent shortcomings increasingly in recent years, such as: network management is difficult to deploy, network security issues become more serious, "best effort forwarding" strategy cannot provide QoS that a user needs, and new applications are difficult to deploy, etc. All of these problems cannot be resolved satisfactorily by "putting-patch" way. It is time to redesign and reconstruct the architecture of Internet. Now some new design ideas about future Internet architecture have been put forward. In this paper, some representatives of these ideas are introduced, and their advantages and defects are analyzed. After these analyses, the possible direction for future Internet design in our opinion is pointed out.
