DISCUSSING AND DESIGN OF SIP ALG;
SIP应用层网关探讨及设计
A detailed analysis of protocol address translation, table management and ALG about NAT-PT are then introduced.
提出了一种基于IXP2400网络处理器的高性能IPv4/IPv6互通网关设计方案,阐述了NAT-PT转换机制中协议地址翻译、映射表管理和应用层网关技术的实现方法,研究了网络处理器环境下硬件资源分配,内部通信机制等问题。
With the state-of-the-art techniques and the SIP protocol, a schema is proposed to support SIP traversing Firewall/NAT (-PT) transparently with the cooperation of SIP ALG and MidCom protocol.
参照当前的SIP穿越技术,结合对SIP协议本身的分析,提出了一种采用应用层网关配合MidCom协议,能够透明地支持SIP穿越带防火墙的NAT和NAT_PT的方案。
In order to realize data synchronization between two databases of two networks with different security levels which are connected by an application gateway, a novel scheme of data synchronization was proposed by taking into account the cases of difficulty to realize data synchronization with the embedded synchronization mechanism of the DBMS.
为了实现位于由应用网关连接的不同安全等级的2个网络中数据库之间的数据同步,考虑到利用数据库管理系统本身具有的同步机制难以实现,提出了一种新的数据同步方案。
Application gateway is one of the systems which emphasize system configurability.
应用网关是一种特别强调可配置能力的系统。
Writers present an improved technology of application gateway that deals directly towards flooding of Email virus and Trojan horse in the download files,also harmful ActiveX codes on homepage,so implement that viruses are scanned and killed by the firewall,and acquire a target that prevent network from destroy of viruses finally.
介绍了传统防火墙的技术特点,分析了现有防火墙技术在保障网络安全方面的不足,针对目前网上邮件病毒泛滥,下载程序中的特洛依木马,以及网页上有害的ActiveX代码等,提出了一种改进的应用网关防火墙技术思想,在防火墙一层实现查毒、杀毒功能,最终达到将各类病毒阻挡在防火墙之外的目的。
