Udp Segmentation Offload, 11. In this talk, Boris Pismenny presented the efforts towards supporting UDP segmentation offload with existing net devices. Segmentation offload reduces send(2) cost by transferring multiple datagrams worth of data as a single large packet UDP Checksum Offload (IPv4 and IPv6) This setting allows the adapter to verify the UDP checksum of incoming packets and compute the UDP checksum of outgoing packets. Because the adapter hardware is able to 数据包不是环回数据包。 UDP/IP 传输卸载的大型 TCP 数据包的 IP 标头中的 MF 位将不会被设置，IP 标头中的 碎片偏移 将为零。 应用程序已指定 UDP_SEND_MSG_SIZE / Segmentation Offloads ¶ Introduction ¶ This document describes a set of techniques in the Linux networking stack to take advantage of segmentation offload capabilities of various NICs. Overview Generic Segmentation Offload (GSO) is a widely used software implementation of TCP Segmentation Offload (TSO), which reduces UDP Segmentation Offload (IPv4 and IPv6) This setting allows the adapter to segment UDP packets with payloads up to 64K into valid Ethernet frames. In USO the host stack creates one super-sized Uses the NIC to handle segmentation, and then adds the TCP, IP and data link layer protocol headers to each segment. These are then indicated Starting in Windows 11, version 24H2, UDP receive segment coalescing offload (URO) enables network interface cards (NICs) to coalesce UDP receive segments. Generic Segmentation Offload (GSO) collectively represents Large Send Offload (LSO) and UDP Send Offload (USO). 8 stable on Linux with an Intel X722 NIC. Generic Segmentation Offload (GSO) Library 6.
