ZTE Corporation ZTE Corporation ZTE Corporation Beijing University of Posts and Telecommunications TSN technology standards developed in the IEEE 802.1TSN Task Group define the time-sensitive mechanism to provide deterministic connectivity through IEEE 802 networks, i.e., guaranteed packet transport with bounded latency, low packet delay variation, and low packet loss.This document summarizes and evaluates various queuing technologies of TSN as reference information for Scaling Deterministic Networks Requirements[I-D.ietf-detnet-scaling-requirements] and Enhancing Deterministic Forwarding.
