A system having scalable sockets to support User Datagram Protocol (UDP) connections identifies a plurality of UDP connections, wherein a plurality of remote clients connect to corresponding ones of the plurality of UDP connections. Each one of a plurality of UDP sockets is associated with a corresponding one of the plurality of UDP connections. A network stack lookup for UDP packets in network traffic is performed using a network stack to identify the UDP socket corresponding to the remote client associated with each of the UDP packet. The UDP packets are buffered with a send buffer and a receive buffer for the UDP socket corresponding to the remote client associated with the UDP packets as determined by the network stack lookup to support communication over the plurality of UDP connections using the plurality of UDP sockets. The system thereby operates more efficiently and/or is more scalable.

Scalable sockets for QUIC

A system for batched User Datagram Protocol (UDP) processing, on a send operation, combines 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 is to be indicated to a corresponding one of the plurality of sockets to convey the plurality of packet batches to a network stack. One call is performed for each indicated socket of the plurality of sockets based on the packet batch size to convey each packet batch to the network stack. The network stack performs a single look up operation and a single network security inspection operation once per packet batch. In response to performing the one call, the plurality of packet batches are then sent to a network adapter or an application. The system thereby operates more efficiently and/or is more scalable.
