随着现代信息技术的飞速发展,各行各业对于信息的依赖程度明显增加。这就对网络的高可用性提出了更高的要求。交换层目前可以通过思科的HSRP技术或者H3C的VRRP技术实现双机热备。而网络安全也是整个网络中的重点,一般常用设备为防火墙,当防火墙接入交换网络时,如果交换网都为双机热备,而防火墙为单节点工作,则会影响整个网络的高可用性。该文即通过目前主流的防火墙厂商天融信的TG-32A-UTM来实现防火墙的双机热备,使整个网络即实现了网络安全的要求,又不影响整个网络的高可用性。
With the rapid development of modern information technology, the dependence of all walks of life on information has obviously increased. This puts a higher demand on the high availability of the network. The switching layer can now be dual-system hot backup through Cisco’s HSRP technology or H3C’s VRRP technology. Network security is also the focus of the entire network. Commonly used devices are firewalls. When a firewall accesses the switching network, if the switching networks are dual-system hot backups and the firewall works as a single node, the high availability of the entire network will be affected. This article through the current mainstream firewall maker Tian Rongxin TG-32A-UTM to achieve dual-firewall hot standby, so that the entire network that the network security requirements, without affecting the high availability of the entire network.
