A Service Curve of Hierarchical Token Bucket Queue Discipline on Soft-Ware Defined Networks Based on Deterministic Network Calculus: An Analysis and Simulation

Shuangyin Ren, Quanyou Feng, Yu Wang, and Wenhua Dou
Abstract—Software Defined Networks (SDN) is an emerging architecture for next generation networks and a network paradigm for 5G mobile networks. This paper presents a QoS research of Hierarchical Token Bucket (HTB) queue discipline on SDN paradigm based on Deterministic Network Calculus. In SDN HTB queue discipline, Network Calculus models were designed for packet classification, policing, filtering and FIFO queue scheduling, bandwidth borrowing mechanism is also discussed in Network Calculus model. In SDN topology level, controller-switch feedback model is discussed. These models were employed in a one-controller one-switch SDN network. Delays for different bandwidth and traffic load are obtained from DNC service curve and arriving curve. An SDN network was simulated in Mininet with a remote layer 2 learning switch controller and an OVS switch under specialized ping traffic. Packet delay from Network Calculus is conformant with Mininet simulation result under comparisons of each other.

Index Terms—SDN/Soft-ware defined networks, network calculus, flow control, HTB/Hierarchical token bucket.
