私有综合服务网络(PISN)是一种专用的、企业级的通信网络,它提供了一系列的通信服务,如语音、数据、图像和视频等。PISN的设计和实现需要遵循一定的标准和规范,以确保网络的可靠性、安全性和互操作性。
ISO/IEC 15055:1997标准是PISN的一个重要标准,它描述了PISN的一个额外网络功能——过境计数器。过境计数器是一种用于计算通过PISN的通信流量的网络功能,它可以帮助企业管理者了解网络的使用情况,优化网络资源的分配和管理。
该标准主要包括以下内容:
1. 规范:描述了过境计数器的功能、性能和接口要求,以及与其他网络功能的集成要求。
2. 功能模型:描述了过境计数器的功能模型,包括输入、处理和输出等模块。
3. 信息流:描述了过境计数器的信息流,包括输入、输出和控制信息等。
该标准的实施可以帮助企业管理者更好地了解PISN的使用情况,优化网络资源的分配和管理,提高网络的可靠性和安全性。
