【Abstract】 This paper analyzes the present situation of Kailuans converged communication system and Hongfeng Company’s communication system is analyzed. The interconnection architecture between Hongfeng wired communication system and Kailuan group ’s converged communication system is planned. The underlying script of SIP protocol for internal relay registration gateway and other devices is written, which realizes the leap from traditional, closed and narrowband voice communication mode to voice, text, video and other multimedia communication. The MSTP + VPN multi-source link transmission mode is studied. The MSTP + VPN link switching mode is designed. The underlying scripts of core switches,firewalls and other devices are written, which improves the security, reliability and availability of the transmission link.更多还原
