Abstract: Client/Server(C/S) pattern is a service-oriented pattern, but transport of network data is address-oriented transport, and they are not consistent. In order to resolve their inconsistency, this paper proposes a concept of Network Service Identifier(NSI), and designs an algorithm of Service-Oriented Networks Transmission(SONT) based on NSI, which uses unicast IP address to implement multicast, supports defense against DDoS attacks on the Internet, and implements transport of service-oriented network data. Theoretical analysis and simulation results show the satisfactory results.

Key words: Client/Server(C/S) pattern, DDoS, multicast, Network Service Identifier(NSI)

摘要： 针对面向服务的客户机/服务器模式与面向地址的网络层数据传输之间的不一致问题，提出网络服务标识(NSI)的概念，设计基于NSI的面向服务的网络数据传输算法。理论分析和实验结果表明，该算法能只通过单播IP地址实现组播，并可防御Internet上的DDoS 攻击。
