However we need the performance of XDP_ZEROCOPY for 10Gbps throughput of the application. We have tried the following to debug the issue: Used a single Spinlock to protect Queues in all ParserThreads just to see if it is a a user-space threading issue. No...

AF_XDPis an address family optimized for high-performance packet processing applications such as firewalls, gateways, and load balancers. Introduced in4.18 Linux kernel, it aims to boost to benefits of AF_XDP in cloud native environments. However, there were two challenges: ease-of-...
A race condition in the virtual ethernet driver of the Linux kernel led to occasional packet content corruptions, which resulted in unwanted packet drops by one of our DDoS mitigation systems. This blogpost describes the thought process and technique we
While the performance evaluation of AF XDP against the legacy protocol stack in the kernel or against DPDK has been studied in the literature, the impact of the multiple socket parameters and the system configuration on its latency has been left aside. To address this, we conduct an ...

When running in the default softirq mode, it is good to have the application and the driver executing on different cores. So, make app_core != queue_id, in a standard Linux config, otherwise performance will suffer. Some interesting capabilities that are demonstrated by xdpsock: ...
