基于H.225.0AnnexG协议的层次化域间通信技术研究

Research of hierarchical inter-domain communication based on H.225 .0 Annex G protocol

目前H.323网络域间通信存在认证授权不完善,效率低等问题。提出了一种基于H.225.0AnnexG协议的层次化管理域间通信体系模型、地址描述符及其域间通信流程的具体实现方式。这种方案采用管理域(AD)中边界单元(BE)与父网守(GK)绑定增强域间的呼叫认证和管理,具有适合视讯网络域间通信管理、减少网络资源浪费及通信效率高的特点。

To solve the inefficient authentication and authorization of inter-domain communication, an improved communication pattern and its communication process between hierarchical AD（ Administrative Domain） was proposed based on the Annex G in H. 225.0 of H. 323 protocol stack. The scheme used the means that it bound parent GK（Gatekeeper） and BE（Border Element） together in an AD to enhance call authentication and management between AD. Compared to other solutions, it can reduce waste of network resource, and it is more adaptive for video communication and more efficient in communication management.
