DPDK Pipeline
Data Plane Development Kit Hardware Acceleration
A framework of fast user-space libraries and poll-mode network drivers that completely bypasses operating system interrupts for maximum packet throughput.
Technical Explanation
Traditional interrupt-driven operating systems choke when handling tens of millions of small packets per second. The Data Plane Development Kit (DPDK) assigns dedicated CPU cores running high-speed Poll Mode Drivers (PMD) that continuously poll network interface cards. Bypassing the Linux network stack entirely, 6G DPDK pipelines achieve packet processing rates exceeding 100 million packets per second per multi-core server.
Key Functions
- Bypassing operating system network stack to process packets in user space
- Poll Mode Drivers (PMD) eliminating interrupt overhead and context switching latency
- Hugepages memory management preventing translation lookaside buffer (TLB) misses
- Lockless ring buffers achieving maximum inter-thread parallel packet processing
- Essential foundation for terabit-rate Extreme-UPF instances in core data centers
