    • A generic master-slave mechanism enables a single processor of a cluster of firewall processors to define the behavior of the other processors in the cluster for a specific logical connection. The cluster of firewall processors utilizes virtual adapters representing physical adapters on other processors in the firewall cluster. This virtualization allows each cluster member to act as though it is a standalone machine that owns all local IP addresses of the entire cluster. When traffic is received by a firewall processor, the firewall processor determines if there is a master associated with the logical connection for the traffic. If so, the traffic is routed to the master. If no master is associated, in an example configuration, the receiving firewall processor becomes the master. A message traffic logical connection has a single master. A master remains the master of a logical connection until the connection is terminated.
    • 通用主从机制使得防火墙处理器群集的单个处理器可以定义集群中其他处理器的特定逻辑连接的行为。 防火墙处理器集群利用虚拟适配器代表防火墙集群中其他处理器上的物理适配器。 这种虚拟化允许每个集群成员就像是拥有整个集群的所有本地IP地址的独立机器一样。 当防火墙处理器接收到流量时,防火墙处理器确定是否存在与流量的逻辑连接相关联的主机。 如果是,则流量被路由到主服务器。 如果没有与主机相关联,则在示例配置中,接收防火墙处理器成为主设备。 消息流量逻辑连接具有单个主服务器。 在连接终止之前,主器件保持逻辑连接的主器件。
