P4 Developer Days – High-Performance Traffic Management: Building a Multi-Layer HCoS Router with P4

Abstract

The Hierarchical Quality of Service (is a very important topic in networking and integrated part of routers. There are few methods used to implement it in hardware in a programmable way possible with P4. The P4 language generally does not define HQoS as a language feature. Instead use the P4 may help defining flexibility in various QoS models implementations.

The presentation shows the hardware extern model based on a sorting engine when connected with P4 creates an opportunity to implement complex scheduling algorithms. Also, the more advanced HQoS topics related to flexible scheduling based on timestamps are covered allowing implementation of TSN protocol families.
