XPF User Guide
Extensible Packet Framework (XPF) is a Huawei-developed library. The XPF function module implements an intelligent offload engine module in the Open vSwitch (OVS) software. This module is used to trace all flow tables and CT tables of data packets in the OVS software. It comprehensively orchestrates the executed CT behaviors and all flow table behavior entries into a comprehensive behavior entry, and generates an integrated flow entry with reference to the unified matching entry. After subsequent data packets enter the OVS, if the packets match the integrated flow table, the comprehensive behavior is directly executed. Compared with the open-source processing flow, the number of query times is reduced, and the performance is greatly improved.
