The Intel Ethernet Connection I225 includes advanced interrupt-handling features to reduce CPU overhead. Other performance-enhancing features include offloading TCP/UDP (for both IPv4 and IPv6) checksum calculations and performing TCP segmentation. Other performance-enhancing features include offloading TCP/UDP (for both IPv4 and IPv6) checksum calculations and performing TCP segmentation.
Advanced features such as Jumbo Frame support for extra-large packets and Receive Side Scaling (RSS) are also supported. Additionally, I225 builds on prior controller solutions to add Time Sensitive Networking (TSN) features including IEEE 802.1Qbu, 802.3br, 802.1Qbv, 802.1AS-REV, 802.1p/Q, and 802.1Qav on select operating systems. These features support advanced time critical, and synchronized applications prevalent in audio/video, embedded, and industrial applications.
Advanced interrupt-handling features manage multiple interrupts simultaneously. Combining interrupt-handling features with intelligent filtering, ordering, and directing packets to specific queues and cores, enables load-balancing network traffic flows to improve throughput in multi-core platforms.
Other performance-enhancing features include IPv4 and IPv6 checksum offload, TCP/UDP checksum offload, extended Tx descriptors for more offload capabilities, up to 256 KB TCP segmentation (TSO v2), 40 KB packet buffer size, and 9.5 KB Jumbo Frame support.
