ITU-T G.7712/Y.1703建议书定义了数据通信网络(DCN)的架构要求,它可支持与电信管理网络(TMN)有关的分布式管理通信、与自动交换光网络(ASON)有关的分布式控制通信(如信令和路由)、与多协议标签交换 – 传送架构(MPLS-TP)有关的分布式控制通信(如信令和路由)、与软件定义网络(SDN)有关的控制通信和其它分布式通信(如指令线或语音通信、软件下载)。DCN架构考虑到了仅IP、仅开放系统接口(OSI)以及混合型(如同时支持IP和OSI)的网络。还规定了支持仅IP、仅OSI以及同时支持IP和OSI的DCN部件之间的互通,而其它协议(IP或OSI除外)超出了本建议书的现有范围。各种应用(如TMN、ASON)要求基于分组的通信网络在不同组件之间传输信息。例如,TMN要求被称为管理通信网络(MCN)的通信网络在TMN组件(如网元功能(NEF)组件和运行系统功能(OSF)组件)之间传输管理消息。ASON要求被称为控制通信网络(CCN)的通信网络、MPLS-TP要求被称为信令通信网络(SCN)的通信网络,在功能管理和控制(MC)组件(如连接控制器(CC)组件和路由控制器(RC)组件)之间传输信令和路由消息。本建议书规定了可用于支持一个或多个应用通信网络的数据通信功能。本建议书2001年版本(版本1)提供的数据通信功能支持无连接网络业务,而本建议书2003年版本(版本2)则通过纳入具体的基于MPLS的机制,增加了对面向连接网络SCN业务的支持。本建议书2010年版本(版本4)提出了对MPLS传送架构(MPLS-TP)信令通信信道(SCC)和管理通信信道(MCC)数据通信功能的要求,其中涉及用于传输网络的MPLS部分符合互联网工程任务组(IETF)确定的MPLS传送架构。若本ITU-T建议书与任何涉及MPLS-TP的具有规范名称的意见征求书(RFC)发生分歧,以RFC为准。2020年版本(版本5)更新了涵盖与软件定义网络(SDN)有关的控制通信。本版本还增加了一个新的附录V,以提供因重构而造成的此处各节与先前版本之间的差异对照。2022年版(5.1版)更新了CCN和DCN的定义,将SCN替换为CCN,将控制组件替换为MC组件,并做了一些编辑上的修改。第8.2.5节的新条款也添加到了MTN ECC的该版本中。本建议书构成了涵盖传输网络的系列建议书的一部分。
