Description
Today, most virtualized functions rely on the Data Plane Development Kit (DPDK) in user space to achieve high data plane packet processing and bypass kernel processing. The XDP ( eXpress Data Path) is an eBPF based high performance data path merged in the Linux kernel since version 4.8. The idea behind XDP is to add an early hook in the receive path of the kernel, and let a user supplied eBPF program decide the fate of the packet.
...
Some key questions to answer are:
- Can this be an alternative to DPDK based solutions?
- What are the parameters that affect the performance - Golden Configuration
- What are the right test methodologies?
- What are the right test-tools - Traffic Generators with test traffic measurements, Packet Forwarders, etc.
