Based on a multilayer service oriented architecture (SOA), one software architecture on large-scale network traffic signal controllers (TSC) system was designed for expedient and effective traffic management. This architecture was achieved by I/O Completion Port (IOCP) mechanism and Web Service technology. IOCP mechanism was adopted not only between the centre control platform and the outfield device, but also between the server and the client of centre control platform. IOCP mechanism managed the communications with numerous TSC and numerous client programs respectively. Web Service technology was applied in the modular centre control platform. Web Service technology encapsulated the relevant information gained during the communication of IOCP mechanism into services, and facilitated the effective integration of the system resource. Moreover, the relationship among the layers of the multilayer SOA was also improved. At last, the implementation of the IOCP mechanism and the Web Service technology in this architecture was introduced in detail. This architecture has been applied in SUPCON Intelliffic software and the application result is very satisfied.
