In the thesis, the author firstly talks about the ecological operation context of web IP, and then the existing problems of the ecological operation of web IP industrial chain, such as the insufficiency in copyright protection, the economic bubbles on its expansion, the lack of originals and the cash-out mentality toward currency. Therefore, the author comes into the conclusion that, there are enormous potentials for the ecological operation of web IP industrial chain. This demands further platforms across the multiple industrial running of web IP, building its brand through the development of"full-copyright". In one word, the life of web IP would be sustained with ecological progress in multimedia consumption, and the ecological operation of web IP industrial chain would be achieved in fact.展开更多

Lot of research has been done in designing architecture for “Web of Things”. Two main architectures are Smart gateway based architecture and embedded Web Server based architectture. These architectures address some of the basic and essential issues relating to Service Oriented Architecture for “Web of Things”. Taking into consideration the period of coexistence of IPv4 and IPv6 we propose an architecture using SOCKS protocol based IPv6/IPv4 gatewaying and refinements which facilitates smooth heterogeneous communications between the IPv6 and IPv4 enabled embedded nodes and can potentially be used to prevent security threats like Denial-of-Service (DoS) attacks on embedded devices attached to the web and increase its performance. Our architecture provides a way for caching responses from device and thereby increasing its efficiency and performance and yielding quick response times.展开更多

We present a robust IP packets filtering mechanism which combines the detection and filtering engine together to protect Web Servers from DDoS Attacks. The mechanism can detect DDoS attacks by inspecting inbound packets with an IP address database, and filter out lower priority IP addresses to preserve the connection for valid users by monitoring the queues status. We use the Netfilter＇s technique, a framework inside the Linux 2.4. X, to implement it on a Web server. Also, we evaluate this mechanism and analyze the influence of some important parameters on system performance. The experimental results show that this mechanism is effective against DDoS attacks.展开更多
