Containerized router is a software router accelerated for giving high performance using the DPDK library. A fundamental requirement for any router (software or hardware) is Quality of Service. In the case of hardware routers, the QOS is implemented in hardware ASICs. Many off-the-self NICs also support it, but it is highly dependent on the capability of the NICs. Moreover, in cloud environments, software NICs won’t have any such capability. So, for cloud native routers, it is best to implement it in software using software queues.

In this talk, we will describe how we are leveraging the DPDK APIs to provide end-to-end quality of service including classification, policing, rewrite, scheduling and shaping for providing QOS in a cloud native software router environment. We will also describe a new and scalable packet processing model for QOS packet scheduling. The end result is a highly scalable, optimal and flexible model to achieve software QOS for use-cases like 5G front haul and mid haul.
