P4 for Custom Identification and Flow Tagging
Nic Viljoen
This tutorial will show the use of P4 on an Agilio CX SmartNIC to enable identification and custom tagging for the rerouting of elastic traffic within a telecoms data center for virtualized compute nodes. The identification is done using real time dynamic measurements of flows on the SmartNIC. Real time dynamic measurement of flows on the SmartNIC is critical for cloud centric service models and service automation. Enabling applications such as security, root cause analysis, big data analytics, and traffic engineering to adjust the depth and complexity of flow monitoring could enable a new wave of sophisticated features and opportunities. The purpose of the talk is to illustrate how these types of applications would benefit from a P4 framework through utilizing P4 interfaces for advanced and customized flow measurements.
