Deterministic Latency Network Framework
Huawei Technologies
More and more real time applications, such as VR gaming, high frequency trading, Internet of vehicle, require accurate latency guarantee or bound, during service provisioning. Providing End-to- End latency guarantee across Internet is increasingly attractive while challenging. The main problem with latency guarantee on Internet is that packet scheduling is still best-effort, and congestion that further introduces latency uncertainty cannot be avoided. This document presents a way of describing latency information that mostly rely on the congestion management such as queue scheduling, and a framework to use such information to guarantee End-to-End latency.
