Abstract: Methods to automatically prioritize input/output (I/O) for Network Function Virtualization (NFV) workloads at platform overload and associated apparatus and mechanisms. During lab or runtime workload operations, various platform telemetry data are collected and analyzed to determine whether a current workload is uncore-sensitive—that is, sensitive to operations involving utilization of the uncore circuitry such as I/O-related operations, memory bandwidth utilization, LLC utilization, network traffic, core-to-core traffic etc. For uncore sensitive workloads, upon detection of a platform overload condition such as a thermal load approaching a TDP limit, the uncore circuitry is prioritized over the core circuitry such that the frequency of the core is reduced first. A closed-loop feedback mechanism is used to adjust the frequencies of the core and uncore under various workload conditions. The mechanism enables I/O throughput to be maintained for NFV workloads, while reducing the processor thermal load.

Abstract: Packets are differentiated based on their traffic class. A traffic class is allocated bandwidth for transmission. One or more core or thread can be allocated to process packets of a traffic class for transmission based on allocated bandwidth for that traffic class. If multiple traffic classes are allocated bandwidth, and a traffic class underutilizes allocated bandwidth or a traffic class is allocated insufficient bandwidth, then allocated bandwidth can be adjusted for a future transmission time slot. For example, a higher priority traffic class with excess bandwidth can share the excess bandwidth with a next highest priority traffic class for use to allocate packets for transmission for the same time slot.
