本标准基于IEEE Std 1888-1中定义的协议，即IEEE无处不在的绿色社区控制网络协议标准，扩展了组件和数据类型定义、消息格式和通信过程，以实现异构网络的融合和可扩展性。本标准还描述了异构网络互连问题和要求。此外，本标准还规定了系统架构和解决方案，以提高异构网络的收敛性和可扩展性，同时提供系统健壮性，并在系统操作和管理方面提供更好的性能。

Based on the protocol defined in IEEE Std 1888-1, IEEE Standard for Ubiquitous Green Community Control Network Protocol, this standard extends component and data type definitions, message formats, and communication procedures for heterogeneous network convergence and scalability. This standard also describes heterogeneous networks interconnection issues and requirements. Also, this standard specifies system architecture and solutions to improve heterogeneous networks convergence and scalability while offering system robustness and supplying better performance in system operation and management.
