Booting DPDK application quickly by device composition - Yahui Cao & Jingjing Wu, Intel
In Cloud-native ages, microservices and containers have gained widespread acceptance in production. For workloads deployed in containers like Cloud-native Network Function, startup time is becoming increasingly important , especially for short-time task at edge. By analyzing DPDK application startup time, there is some overhead(like general init/reset) impacts on startup time which needs to be addressed. By using software mediation, device composition, which is leveraged by Intel Scalable I/O Virtualization Specification, can ease the overhead and greatly decrease application startup time. And this is device-type agnostic benefit. This presentation will cover below items: 1. Why DPDK startup time matters 2. What's the problem in DPDK application startup time 3. How device composition decreases DPDK application startup time 4. How Intel Scalable I/O Virtualization enabled platform and NIC decrease DPDK application startup time
