Batch processing for QUIC

A computerized method for batched User Datagram Protocol (UDP) processing, the computerized method comprising:

• combining multiple UDP packets into a plurality of packet batches to indicate on a plurality of sockets based at least in part on a packet batch size, each packet batch of the plurality of packet batches to be indicated to a corresponding one of the plurality of sockets with message boundary information to convey the plurality of packet batches to a network stack, the message boundary information indicating portions of a payload of the plurality of packet batches that correspond to a plurality of individual messages and identifying a size of the individual messages corresponding to the payload of each of the UDP packets that have been combined;
• performing one call for each indicated socket of the plurality of sockets based on the packet batch size to convey each packet batch of the plurality of packet batches to the network stack, wherein the network stack performs a single look up operation and a single network security inspection operation once per packet batch;
• and
• sending, in response to performing the one call, the plurality of packet batches via the network stack, wherein (i) on a send operation, the plurality of packet batches are sent from the network stack to a network adapter for transmission over a network, and (ii) on a receive operation, the plurality of packet batches are sent from the network stack to an application, wherein a maximum segment size (MSS) parameter is used to offload generation and attaching of a UDP/IP header to each packet batch, the UDP/IP header and the payloads forming the plurality of packet batches and configured using a QUIC transport layer protocol.

One or more computer storage media having computer-executable instructions for batched User Datagram Protocol (UDP) processing that, upon execution by a processor, cause the processor to at least:

• combine multiple UDP packets into a plurality of packet batches to indicate on a plurality of sockets based at least in part on a packet batch size, each packet batch of the plurality of packet batches to be indicated to a corresponding one of the plurality of sockets with message boundary information to convey the plurality of packet batches to a network stack, the message boundary information indicating portions of a payload of the plurality of packet batches that correspond to a plurality of individual messages and identifying a size of the individual messages corresponding to the payload of each of the UDP packets that have been combined;
• perform one call for each indicated socket of the plurality of sockets based on the packet batch size to convey each packet batch of the plurality of packet batches to the network stack, wherein the network stack performs a single look up operation and a single network security inspection operation once per packet batch;
• and
• in response to performing the one call, send the plurality of packet batches via the network stack, wherein (i) on a send operation, the plurality of packet batches are sent from the network stack to a network adapter for transmission over a network, and (ii) on a receive operation, the plurality of packet batches are sent from the network stack to an application, wherein a maximum segment size (MSS) parameter is used to offload generation and attaching of a UDP/IP header to each packet batch, the UDP/IP header and the payloads forming the plurality of packet batches and configured using a QUIC transport layer protocol.
