  • Patent number: 11128494
    Abstract: Methods, computer program products, and systems are presented. The methods include, for instance: a gateway stack that includes a master, a backup, and at least one slave amongst nodes of the GS based on an election pursuant to a gateway stack protocol. The gateway stack provides gateway services for a Network Virtualization over Layer 3 (NVO3) network in a fail-safe manner by utilizing all of the nodes in the gateway stack. A data interface between the gateway stack and a switch is aggregated to evenly distribute inbound packets amongst the nodes of the gateway stack.
    Type: Grant

  • Patent number: 10277423
    Abstract: Methods, computer program products, and systems are presented. The methods include, for instance: providing a distributed virtual gateway for Network Virtualization over Layer 3 (NVO3) network. A gateway stack having three or more nodes is implemented as a distributed virtual gateway, providing Layer 2 or Layer 3 gateway services in a fail-safe manner. Nodes of the gateway stack are configured to autonomously process and forward inbound NVO3 data packets with known destination addresses without engaging a master of the gateway stack.
