网关控制协议:第3版 |
为了获得更好的可扩展性,本建议书将ITU-T H.246建议书定义的H.323网关功能分解为多个子功能实体,并且制定协议用于子功能实体之间进行通信。这使H.323网关的部署具有高度的可扩展性,并鼓励使用SS7交换机等广泛部署的电路交换网络(SCN)能力。同时H.323网关功能也可以由隶属于多个设备制造商分布在多个物理平台的功能实体组合完成。本建议书的目的是在现有H.323系统所支持的功能上扩展新的功能,以及在现有H.323系统所支持的操作模式的基础上提供一种新的模式。这一修改包括关于以下问题的一系列说明:– 新流式传输的信号状态;– 基于时间的统计数据及其对多流媒体的适应性;– 模式属性对统计数据的影响;– 与新流式传输相关的事件状态;– ServiceChange版本的处理。 |
