Abstract
Methods and systems for network communication are provided. One method includes, receiving a network packet at a first network interface card (NIC) operationally coupled to a computing device; identifying a second NIC as a destination for the network packet; placing the network packet by the first NIC at a host memory location, without utilizing resources of a processor of the computing device; notifying the second NIC that the network packet has been placed at the host memory location; retrieving the network packet by the second NIC from the host memory location; transmitting the network packet by the second NIC to another destination; notifying the first NIC by the second NIC that the packet has been transmitted by the second NIC; and freeing the host memory location by the first NIC.
