  • Firewall cluster
    Patent number: 10715490
    Abstract: A Software Defined Network (SDN) controller monitors load of Virtual FireWall (vFW) nodes in a firewall cluster in real time. When detecting that load of one or more vFW nodes is higher than a predefined first threshold, the SDN controller creates a new vFW node. The SDN controller selects a first flow, which is to be migrated, from flows passing through the monitored vFW nodes, updates a first flow entry corresponding to the first flow, and sends the updated first flow entry to a switch. The updated first flow entry indicates the switch to send the first flow to the new vFW node.
