Considering the netscreen of network devices, the design of a special backup "NetScreen Redundancy Protocol (NSRP)", Redundancy Protocol (NSRP) is a proprietary protocol supported on selected NetScreen devices that provides high availability (HA) services. To normally play the role of a network firewall, the NetScreen device must be placed on a single point in which traffic must be passed between all segments. Therefore, it is essential to maintain f
