Broadband Network Lab, Dept. of CE, National Central University Mininet for AVB system Prof. Yen-Wen Chen Student Kuo-Che Kao 2020/4/7
Broadband Network Lab, Dept. of CE, National Central University Outline Introduction Topology QoS rule Result 1
Broadband Network Lab, Dept. of CE, National Central University Introduction 2
Broadband Network Lab, Dept. of CE, National Central University Introduction According to AVB credit based shaper: Simulate this method by mininet and sdn ryu-manager (queue QoS) 3
Broadband Network Lab, Dept. of CE, National Central University Topology 4
Broadband Network Lab, Dept. of CE, National Central University Topology Node A 10.0.0.1 SR class eth1 Switch Target Node B eth4 eth2 10.0.0.2 eth3 10.0.0.4 Node C Best-effort 10.0.0.3 5
Broadband Network Lab, Dept. of CE, National Central University QoS rule 6
Broadband Network Lab, Dept. of CE, National Central University QoS rule Default : Minimumrate Maximumrate Queue 0 (10.0.0.1) 37.5Mbps 100Mbps Queue 1 (10.0.0.2) 37.5Mbps 100Mbps Queue 2 (10.0.0.3) 0Mbps 100Mbps If credit value < 0 : Minimumrate Maximumrate Queue 0 (10.0.0.1) 0Mbps 100Mbps Queue 1 (10.0.0.2) 0Mbps 100Mbps Queue 2 (10.0.0.3) 0Mbps 100Mbps 7
Broadband Network Lab, Dept. of CE, National Central University QoS rule Credit value : If queue bytes change > 0 : credit value +3 If queue bytes change = 0 : credit value -1 If queue bytes change = 0 twice : credit value = 0 -3 <= credit value <=3 8
Broadband Network Lab, Dept. of CE, National Central University Result 9
Broadband Network Lab, Dept. of CE, National Central University Result If just use default QoS setting: 10
Broadband Network Lab, Dept. of CE, National Central University Result Use credit based shaper: 11
