由于SNMP(S imp le Network M anagem ent Protocol)管理系统在配置管理方面具有一定弱点。Net-conf协议被认为是解决网络配置管理问题较为有效的方法。文中采用XML Schem a描述网络管理系统的数据模型,并且为了保证Netconf配置操作的事务可靠性,在Netconf的概念模型基础之上定义了网络管理应用操作层。同时也描述了基于Netconf的网络管理系统的系统结构和实现模型,提出了用于建立网络管理应用系统的设计模式,最后介绍了开发基于XML网络管理系统的经验。
Parlay Multi Media Call Control Services ( MMCCS) Application Programming Interfaces (API) based on Session Initiation Protocol (SIP) is essential for the implementation of Parlay Call Control ( CC) API. This paper first proposes an implementation model of Parlay MMCCS API based on SIP, then presents a mapping between SIP and MMCCS AP1 as far as methods and parameters are concerned, illustrates corresponding relationships between different components of SIP and MMCCS API by means of an application collaboration diagram, and finally presents an application using Java codes as well as some SIP messages. The application shows that a majority of MMCCS API based on SIP can be implemented and therefore verifies our mapping between MMCCS API and SIP.
