- 10. www.glcnetworks.com What is QOS ● Quality of service (QoS) ● description or measurement of the overall performance of a service, such as a telephony or computer network or a cloud computing service, particularly the performance seen by the users of the network 10 Source: microsoft
- 11. www.glcnetworks.com When you don’t need QoS? ● You have enough bandwidth for your consumption ● No complain from customers ● You are welcome to quit this webinar 11
- 12. www.glcnetworks.com Do you need QoS? ● When you available bandwidth < consumption 12 Source: mrtg
- 13. www.glcnetworks.com constant vs bursty traffic ● Steady traffic ○ Always consume fixed traffic ○ Example: voip, streaming, file transfer ● Bursty traffic ○ Only consume traffic when its active ○ Example: browsing, messaging, email 13 Source: www.viavisolutions.com
- 14. www.glcnetworks.com What will QoS do ● Setup limitation ○ Max-limit ○ Min-guaranteed limit ● Setup priority ● Burst 14
- 15. www.glcnetworks.com How to measure QoS? ● Depends on the applications ● Some common parameters ○ packet loss ○ Throughput ○ Latency (roundtrip time) ○ Jitter (variance of latency) 15
- 16. www.glcnetworks.com QOS or QOE? ● QOE: Quality Of Experience ○ The degree of delight or annoyance of the user of an application or service ○ Reference: ITU (https://www.itu.int/rec/T-REC-P.10) ● QOE factors: ○ QoS, ○ Human ○ context 16 Source: researchgate
- 17. www.glcnetworks.com Is QoS end-to-end? ● Internet is a collection of networks ● Can you guarantee end-to-end QoS? 17 Your ISP. and you are part of them other ISP other ISP google facebook
- 19. www.glcnetworks.com Network queue in Linux ● Mikrotik uses Linux kernel ● Happens on interface ● What we queue? Packets. Not bytes / bits ● 19
- 20. www.glcnetworks.com Queue on router ● Can be done on inbound or outbound interface 20 Source: Network QoS using Cisco
- 22. www.glcnetworks.com Where the packets are queued?
- 23. www.glcnetworks.com Bandwidth management mechanism Mikrotik uses Hierarchical Token Bucket (HTB) algorithm for managing the queue: to define the limit of datarate Scheduling algorithm: ● FIFO (first in first out) ● RED (Random Early Detection) ● SFQ (Stochastic Fair-share Queue) ● PCQ (Per-Connection Queue)
- 25. www.glcnetworks.com Queue size: discard vs delay (limiting vs equalizing) Rate limiting Rate equalizing Mechanism discard packets that exceed a limit delay packets that exceed a limit if possible Queue size (buffer) 0 > 0
