  • Address resolution protocol suppression using a flow-based forwarding element
    Patent number: 10798048
    Abstract: A method of suppressing ARP packets in a logical network comprising a set of data compute nodes (DCNs). The DCNs are hosted on a set of physical hosts. Each DCN has a protocol address and is connected to a forwarding elements (FE) on the corresponding host. Each FE has a set of flows that specifies a set of conditions to match a set of fields of each received packet and a set of actions to take on a packet that matches the set of conditions. An FE on a physical host receives a packet sent by a first DCN on the physical host and determines that the received packet is an ARP request packet by matching a set of fields in the packet with a set of conditions of a particular flow. The ARP request packet identifies a protocol address of a second DCN on the logical network.
