China Unicom China Unicom China Unicom ZTE Corporation ZTE Corporation In deterministic networking (DetNet), strict resource reservation and scheduling assumptions may encounter anomalous traffic conditions at flow aggregation nodes due to microbursts, packet size variations, or control plane orchestration limitations. These conditions represent deviations from the ideal deterministic service model rather than network faults. Existing data plane mechanisms for handling anomalous packets, such as simple discarding or treating them as Best-Effort (BE) flows, are insufficient. Consequently, the network performance can degrade to a level inferior to of traditional QoS approaches.Therefore, in order to handle the anomalous traffic, the data plane should implement an enhanced handling mechanism. This document proposes an enhanced anomalous traffic handling solution for DetNet. This solution specifies two policies for handling traffic under anomalous conditions: the squeezing policy and the degrading policy. These policies provide a flexible, enhanced mechanism applicable to various queuing mechanisms, ensuring the preferential scheduling and preservation of deterministic service traffic under anomalous conditions.
