摘要

摘要:
为了实现四表(水，电，气，热)集抄行业之间的业务数据隔离，提升本地网络的稳定性和覆盖能力，该文提出四表集抄通信网络虚拟化方案。该方案采用虚拟接入点名称(APN)技术以及软件定义网络(SDN)切片技术构成端到端隔离的业务数据采集通道；采用微功率无线和低压电力线载波构成实时可靠的本地双模虚拟网络，进一步提出基于全局链路状态和分层迭代的组网算法。仿真及现场验证结果表明，该方案降低了采集数据的丢包率和传输时延，提高业务支撑能力，保障行业之间的业务数据隔离，提升通信网络基础设施复用能力。

Abstract:
In order to achieve service data isolation in advanced metering Infrastructure for water, electricity, gas, and heat Meters and improve the stability and coverage of local data collection network, a network virtualization scheme of Advanced Metering Infrastructure (AMI) is proposed. In this scheme, the end-to-end isolated service data collection channels are constructed utilizing virtual Access Point Name (APN) and Software Defined Network (SDN) slice technology. The micro-power wireless and low-voltage power line carriers are used to constructed a real-time and reliable local dual mode virtual network. Furthermore, the networking algorithm based on global link-state and hierarchical iterative algorithm are proposed. The simulation and experiments show the packet loss rate and transmission delay of collected data are decreased utilizing the proposed scheme, and business support capability is improved. Moreover, the service data isolation is implemented in AMI for water, electricity, gas, and heat Meters and multiplexing ability of communication network infrastructure is improved.
