摘　　要：宽带视频点播计费系统以分布式并行操作系统和分布式并行数据库系统为基础,通过量化的计费进程激活指数,结合计费进程互斥进入临界区算法,实现了多进程分布式协同计费。系统具有负载均衡能力,能够自动选择负载最轻的服务器作为计费节点。引入迁移惰性指数,使进程迁移的可控性得到进一步提高。系统具有很强的稳健性、实时性和不间断性的优点。该计费系统的设计方法不仅适用于宽带视频点播计费系统,也可供其它相近或相关计费系统借鉴。Based on distributed parallel operating system and distributed parallel database system, charging system for broadband video on demand realized multi-process distributed co-charging through the quantization activating index of charging process and the mutual exclusion algorithm of charging process entering critical zone. The system has load balancing ability, can choose the tightest load node as charging server automatically. The controllability of process migration is improved further by introducing the migration inertia index. The system has very strong robustness, real-time character and continuous advantage. The design method of this charging system is not only suitable for the charging system of broadband video on demand but also for other close or relevant charging systems to consult.
