Research on QoS Policy Deployment Approach of DiffServ Model Based on GNS3

Abstract

Based on DiffServ model architecture model, GNS3 network simulator is used to build a virtual network environment; on this basis, the main QoS technology is analyzed and discussed in DifferServ model and MQC deployment is used to ensure QoS policies of low-latency operations; SLA job simulation is used to produce different types of data traffic and the main performance parameters are detected in three cases of the normal network, congestion and the implementation of QoS policies; the experimental results verify the correctness and practical feasibility of the method.
