The board itself uses up to 45W of power, while the I am wondering what happens when I tick Software flow offloading and/or Hardware flow offloading while having SQM enabled. This add latency, and because all packets need to be sending out again, the stack have to split in different packets again before to hand them down to the NIC. If you turn on software offloading it may change exactly how cake handles thing potentially, but it also might be specific to diffserv8 which is I think an unusual config. flow_offloading_hw='1' # save settings uci commit # restart firewall to apply these settings /etc/init. This is with PFBlockerNG and Snort enabled on LAN. For example, if there are two VLAN interfaces (vlan20 and vlan30) running on the same switch port (trunk port), it is impossible to enable hardware Hardware offloading can be used to accelerate VLAN and VXLAN networking using the capabilities of the underlying network card to achieve much higher performance than with virtio based VM ports. 2 on my Ubiquiti EdgeRouter X. 20. 0 record layer protocol: /etc/nginx This paper introduces Triton, a flexible hardware offloading architecture for accelerating AVS. Description. After reading through the MediaTek SDK, I have a reasonable handle on how the accounting works in the packet processing engine, and I think it should be possible to keep accurate per-flow metrics with (typically) minimal performance impact. 4 EdgeOS firmware releases, additional offloading optimizations are available:. This is what is called Layer 3 Hardware Offload. Layer 3 Hardware Offloading (L3HW, otherwise known as IP switching or HW routing) allows to offload some router features onto the switch chip. Slides: https://box. Examples of these include VMMQ, VMQ, Send-side IPv4 Checksum Offload, and RSS.
