EC 61850-8-2:20 18规定了通过任何类型的网络（包括公共网络）交换数据的方法。在IEC 61850-7-2规定的各种服务中，到目前为止只考虑了客户机/服务器和时间同步服务。 注意GOOSE和SMV模型的客户机/服务器服务也被映射。 对于客户机/服务器服务，其原理是将ACSI（IEC 61850-7-2中定义的抽象通信服务接口）的对象和服务映射到通过XMPP传输的XML消息。映射描述主要包括三个方面: ？XMPP协议本身的用法，详细描述哪些特性真正被使用，以及映射如何使用它们。 ？如何实现端到端的安全通信。 ？对与每个ACSI服务相对应的XML有效负载的描述特别归功于XML模式和XML消息示例。

EC 61850-8-2:2018 specifies a method of exchanging data through any kinds of network, including public networks. Among the various kinds of services specified in IEC 61850-7-2, only the client/server and time synchronization services are considered so far.
NOTE Client/server services of GOOSE and SMV models are mapped as well.
For the client/server services, the principle is to map the objects and services of the ACSI (Abstract Communication Service Interface defined in IEC 61850-7-2) to XML messages transported over XMPP. The mapping description includes mainly three aspects:
？The usage of the XMPP protocol itself, describing in details which features are really used and how they are used by the mapping.
？How to achieve end-to-end secured communications.
？The description of the XML payloads corresponding to each ACSI service thanks in particular to the XML Schema and XML message examples.
