基于分布式计算总线的计费系统实践

计费系统是通信运营商业务支撑系统中的核心系统之一。针对旧计费系统存在性能瓶颈、不支持容器化和微服务化扩展等问题,本文提出了基于分布式计算总线的解决方案,对系统架构、MDB、文件负载均衡等进行了升级,同时也进行了国产化操作系统的适配改造,接入统一PaaS平台,进一步增强国产化自主可控能力。实施后,相关应用数据表明新计费系统更加易用、高效和安全,系统水平扩展能力得到提升,满足了海量数据高并发访问的需求,可较好地灵活支撑业务发展和业务运维。

面向SOA的电力分布式计算总线的应用研究

为了实现数据资源广域分布的电网系统分布式分解协调计算,提出了面向服务架构的电力分布式计算总线(EDCB)协调机制。采用主从分层分区方法,把互联的电力网络划分成主区和从区,在分区环境下分析电力分布式计算的数据需求、计算环境和计算结构,设计电力分布式计算总线模型,进行分布式分解协调计算。通过Ward等值方法,把电网数据转换成数据量较小的等值数据,并利用SOA技术实现分布式计算总线。

NOVEL AIRCRAFT ELECTRICAL POWER DISTRIBUTION SYSTEM BASED ON DISTRIBUTED COMPUTER

As a matured technique used in many fields,the distributed computer system is still a new management method for the aeronautical electrical power distribution system in our country. In this paper, a novel aircraft electrical power distribution system based on the distributed computer system is proposed. The principles, features and structure of the aircraft electrical power distribution system and the distributed computer system named electrical load management system (ELMS) are studied. The ELMS composed of four electrical load management centers (ELMCs) and two power source processors (PSPs) operates in the 1553B buses. Principles of the ELMCs and the PSPs are introduced. With the application of the distributed computer system, the aircraft electrical power distribution system is simple, adaptable and flexible.
