Keywords: Bandwidth, QoS, Video Conference, Codec


Video conference is a service that is capable of sending audio and video data simultaneously. In its work requires a codec to compress audio and video data to save bandwidth, processor work, and memory. There are two video conferencing services that are popularly used today, namely Zoom Cloud Meetings which uses the H.264/SVC codec and Google Meet which uses the VP9 codec. Meanwhile, video conferencing activities consume a large volume of data, so it is necessary to know which codec is the most efficient in bandwidth usage. Therefore, this research was conducted to determine the bandwidth requirements, QoS performance, and the use of processor and memory resources by codecs in the two video conferencing services. The analysis was carried out on 10 users within 10 minutes with 4 test scenarios. Bandwidth and QoS were analyzed using Wireshark tools. The results of the analysis show that the lowest average bandwidth requirement is found in the use of Google Meet, which is 1,5 Mbps at HD resolution and 0,88 Mbps at SD resolution. For the average value of the QoS parameters on the two video conference services, it shows that the network performance is in very good condition and is comparable between the two video conference services at the time of testing. The lowest memory and GPU resource usage is on Google Meet, which is 148,3 MB and 2,65 %,, while the lowest processor resource usage is on Zoom Cloud Meetings, which is 2,5%. With a combination of video conferencing and presentation scenarios, Google Meet consumes 1,20 GB of data volume, while Zoom Cloud Meetings is 1,45 GB. From the results of this analysis, it can be concluded that the VP9 codec used by Google Meet is more bandwidth efficient in video conferencing activities than the H.264/SVC codec used by Zoom Cloud Meetings.
