The flood of spam has caused more serious harm in society. In this paper, we bring forward an anti-spam system based on the service grid, which can dynamically organize the mail servers on the Internet together to against the spam. We discuss the working model and system architecture of the anti-spam grid and design the core algorithm for the status monitoring and load distribution of a dispatch server. And In this paper, we implement the system performance evaluation, and the experiment results show that the system is stable, efficient and scalable.

The current global Internet USES the TCP/IP protocol cluster. IP is the network layer protocol and the core protocol in this protocol family. The current version is IPv4 with 32-bit addresses. With the popularity of Internet applications, the limited address space defined by IPv4 has been exhausted. To expand the address space, the Internet Engineering Task Force (IETF) has designed the next generation IP protocol, IPv6, to replace IPv4. IPv6 redefines the address space, using a 128-bit address length that provides almost unlimited addresses. However, with the development and application of the Internet of things, big data and cloud storage, IPv6 has some shortcomings in its address structure design, security and network sovereignty, so it is urgent to develop a new generation or future internet with security and reliability, autonomy and controllable , and it becomes a research hotspot in the world. This paper developed a new generation Internet (IPV9) datagram by researching the existed IPv4 and IPv6, and it is based on the method of assigning addresses to computers connected to the Internet by full decimal character code which designed by the Chinese Decimal Network Working Group with the leader of Xie Jianping. It is a subsequent version with RFC1606, RFC1607, a new generation of network data structure, it is not the updating of IPv4 [RFC-791] and IPv6 [RFC-1883], [RFC-2464], it is a new vision to demonstration and testing.

Network system structure is the basis of network communication. The design of network model can change the network structure from the root, solve the deficiency of the original network system, and meet the new demand of the future network. TCP/IP as the core network technology is successful, it has shortcomings but is a reasonable existence, will continue to play a role. Considering the compatibility with the original network, the new network model needs to be compatible with the existing TCP/IP four-layer model, at the same time; it can provide a better technical system to implement the future network. Based on the Internet three-layer/four-layer hybrid architecture TCP/IP/M and ISO/IEC next-generation Internet standard solutions, this paper proposes the IPV9 system architecture, which can directly transmit audio and video data with three layers on the premise of not affecting the existing four-layer network transmission. The hybrid structure is a new transmission theory, which requires the establishment of a link before data transmission and the withdrawal of the link after the transmission is completed. It solves the problem of high-quality real-time media communication caused by the integration of three networks (communication network, broadcasting network and Internet) from the underlying structure of the network, realizes the long-distance and large-traffic data transmission of the future network, and lays a solid foundation for the digital currency and virtual currency of the Internet. The system framework is verified by practical application. It have been deployed to verify the compatibility and reliable transmission between IPV9 network and the existing network, under the independent, reliable, secure and controllable network architecture, a new generation of master root server and 13 root domain name servers.
