Patent number: 11068362Abstract: Methods and systems are provided for an improved cluster-based network architecture. According to one embodiment, an active connection is established between a first interface of a network device and an enabled interface of a first cluster unit of an HA cluster of network security devices. The HA cluster is configured to provide connectivity between network devices of an internal and external network. A backup connection is established between a second interface of the network device and a disabled interface of a second cluster unit. While the first cluster unit is operational and has connectivity, it receives and processes all network traffic from the network device that is destined for the external network. Upon determining the first cluster unit has failed or has lost connectivity, then all subsequent network traffic originated by the network device that is destined for the external network is directed to the second cluster unit.Type: GrantFiled: April 27, 2018Date of Patent: July 20, 2021Assignee: Fortinet, Inc.Inventors: Michael Xie, Jingyu Liu, Xianfeng Deng

Patent number: 9965368Abstract: Methods and systems are provided for an improved cluster-based network architecture. According to one embodiment, an active connection is established between a first interface of a network device and an enabled interface of a first cluster unit of a high availability (HA) cluster. The HA cluster is configured to provide connectivity between network devices of an internal and external network. A backup connection is established between a second interface of the network device and a disabled interface of a second cluster unit. While the first cluster unit is operational and has connectivity, it receives and processes all traffic originated by the network device that is destined for the external network.

Publication number: 20140156812Abstract: Methods and systems for temporarily configuring a network appliance in accordance with externally provided customized configuration settings are provided. According to one embodiment, a network appliance may operate in one of multiple configuration modes, including an internal configuration mode and an external configuration mode. When operating in the internal configuration mode, the network appliance loads and runs configuration settings from a memory internal to the network appliance. When operating in the external configuration mode, the network appliance loads and runs configuration settings from an external storage device coupled to an interface of the network appliance.Type: ApplicationFiled: December 5, 2012Publication date: June 5, 2014Applicant: Fortinet, Inc.Inventors: Xianfeng Deng, Ihab Khalil
