What is the correct sequence of events for offloading by the Intelligent Traffic Offload (ITO) service?
The correct sequence for offloading by the Intelligent Traffic Offload (ITO) service is: First, sample packets are sent to ITO to determine the flow's characteristics. Then, ITO instructs the Smart NIC whether to inspect or bypass the flow. For offloading, the Smart NIC forwards the flow directly to its destination. This sequence ensures that the flow is correctly handled, reducing the inspection load on the VM-Series and improving performance.
"C" is the correct answer. The question is asking for the events for "offloading", not for "inspecting". Therefore the correct sequence is... 1) Sample packets sent to ITO 2) ITO instructs Smart NIC to inspect or bypass (bypass is the same as saying "offload") 3) Smart NIC forwards flow directly to destination (this is call "offloading" and bypasses inspection) Check out "Figure 2: ITO offload use case" in this blog: https://live.paloaltonetworks.com/t5/community-blogs/boost-vm-series-performance-with-smartnic-integration/ba-p/413658
A I read it as, ITO decides which traffic will be bypassed and send rest of traffic for inspection.
For each new flow on the network, the Intelligent Traffic Offload service determines whether or not the flow can benefit from security inspection. The determination is made based on either policy or the flow’s inability to be inspected (i.e., encrypted traffic). If the flow is deemed unfit for inspection, it is offloaded to the Smart NIC, saving the need for the firewall to analyze it, which reduces load on the firewall and increases performance.
