Abstract: A system and method can support flooding mechanism using a packet process proxy in a middleware machine environment. The middleware machine environment can comprise a gateway instance that includes an external port for receiving data packets from an external network. The middleware machine environment also comprises one or more host servers, each of which is associated with one or more virtual machines. Furthermore, said host servers can provide virtual interfaces that belong to a virtual hub associated with the gateway instance. At least one said packet is a flooded packet that is specified with an unknown destination address when it is received at the external port. The gateway instance can send the flooded packet to a designated virtual interface on a host server, and a packet process proxy on the host server can forward the flooded packet to a virtual machine on another host server for processing this packet.

Abstract: A system and method can support a scalable packet forwarding mechanism in a middleware machine environment. The middleware machine environment can comprise one or more network switch instances, wherein each network switch instance is associated with one or more external ports that are adapted to receive data packets from an external network. Furthermore, the middleware machine environment can comprise a plurality of packet dispatching components, each of which is responsible for forwarding a data packet to a virtual machine on a host server that operates to process the data packet. Additionally, a link aggregation component can combine multiple external ports into a logical port, and wherein the bandwidth of the logical port is linearly scaled accordingly to a total number of the multiple external ports.
