Publication number: 20220393977Abstract: Systems and methods of offloading multicast virtual network packet processing to a network interface card are provided. In an example implementation, a network interface card can route packets in a virtual network. The network interface card can be configured to receive a data packet having a multicast header for transmission to a plurality of destination virtual machines. The network interface card can retrieve a list of next hop destinations for the data packet. The network interface card can replicate the packet for each next hop destination. The network interface card can encapsulate each replicated packet with a unicast header that includes a next hop destination virtual IP address indicating the next hop destination and a source virtual IP address, and transmit the encapsulated packets.Type: ApplicationFiled: August 18, 2022Publication date: December 8, 2022Inventors: Prashant R.

Publication number: 20220337675Abstract: A communication protocol system is provided for reliable transport of packets. In this regard, an initiator entity may determine that outgoing data is to be transmitted to a target entity. The initiator entity may transmit, to the target entity, a solicited push request requesting the outgoing data to be placed at the target entity. In response to the solicited push request, the initiator entity may receive a push grant from the target entity. In response to the push grant, the initiator entity may transmit to the target entity the outgoing data to be placed at the target entity.Type: ApplicationFiled: July 5, 2022Publication date: October 20, 2022Inventors: Weihuang Wang, Prashant R.

Publication number: 20220269569Abstract: Systems and methods of error handling in a network interface card (NIC) are provided. For a data packet destined for a local virtual machine (VM), if the NIC cannot determine a valid translation memory address for a virtual memory address in a buffer descriptor from a receive queue of the VM, the NIC can retrieve a backup buffer descriptor from a hypervisor queue, and store the packet in a host memory location indicated by an address in the backup buffer descriptor. For a transmission request from a local VM, if the NIC cannot determine a valid translated address for a virtual memory address in the packet descriptor from a transmit queue of the VM, the NIC can send a message to a hypervisor backup queue, and generate and transmit a data packet based on data in a memory page reallocated by the hypervisor.Type: ApplicationFiled: May 10, 2022Publication date: August 25, 2022Inventors: Prashant R.
