“…A dynamic core allocation to enhance the packet scheduling in multicore network processors is proposed by Iqbal et al (2016). They have considered a packet scheduling scheme that incorporates various dimensions of the locality to enhance throughput for network processors and minimize out of order packets.…”

“…However, since the data plane is offloaded to the SmartNICs, the traffic flowing through the SmartNICs gradually becomes a black box, posing severe challenges to monitoring and operation requirements [4]. Besides, mice flow accounts for the majority of network flows [7], offloading these mice flow would exhaust the limited flow table of SmartNICs. The fleeting nature of mice flow also makes them very difficult to monitor, especially for SmartNICs.…”

The explosive increase in cloud traffic has put forward higher requirements for network performance. As a key technology, smart network cards(SmartNICs) are of great significance for solving network performance bottlenecks in cloud environments. However, there is currently a lack of effective monitoring methods for the traffic flowing through smart network cards, making it a black box, which is not friendly to ensure the quality of service(QoS) for users. To alleviate it, in this paper, we propose a low-overhead collaborative design for data collection based on XDP in which the XDP program is attached to the VF representor(VF rep) which is the mandatory path for every traffic flow that is about to be offloaded to the SmartNIC to capture the necessary traffic information, and then the OVS command is used to obtain detailed traffic statistics offloaded. The collaborative design not only provides sufficient valuable information for SREs to understand the health status of the network, which is important for the QoS assurance but also has negligible performance overhead due to the inherent low overhead of the XDP program. Experimental results show that the proposed method costs less than 1% latency and throughput overhead to provide the desired information, which demonstrates our method is effective.
