An architecture com- bining an Information-Centric Network (ICN) and Sottware-Defmed Network (SDN) (IC-SDN) has gradually attracted more attention. How- ever, the existing studies regarding IC-SDN still lack support in terms of the "network status awareness" function, resulting in unreasonable resource allocation. In this paper, we propose a new status-aware resource adaptation sche- me, i.e. a status-aware module is embedded into basic elements (Forwarding Node (FN) and Resource adaption Manager (RM)). The FNs collect the network status dynamically for the controller to reallocate network resources accor- ding to the fluctuations in environmental con- ditions. Simulation results show that, compared with the existing IC-SDN mechanism, the pro- posed scheme reduced the link bandwidth var- iance by 56% and the content delivery latency by 40%. The proof-of-concept implementation demonstrates the feasibility of our proposed sc- heme for small-scale deployment.展开更多

Compared to western countries, design works of China have obvious disadvantages. At the same time, the traditional handicraft techniques of China have suffered strong blows of modem technologies with the development of time and their living space have been gradually occupied. The combination of traditional handicraft techniques with modem fashion design has dual significances. On the one hand, it helps infuse new ideas into fashion design. On the other hand, it promotes the development of traditional handicraft techniques in modern times. In this respect, this combination has some positive significances.展开更多
