A QoS-enabled secure LAN access control system

Centralized access control systems improve security and management feasibility in secure LAN (SLAN) system, but also bring in weak extensibility. System delay becomes non-ignorable facing with frequent requests from mass clients. We describe the design, implementation, and performance of a QoS-enabled system for access control system on SLAN. The system optimizes the flexibility and security. Through experiment, we prove that it increases the efficiency of request processing.
