Since the vast majority of webcams now use VoIP connections between parties, it is important that you pre-address a number of common performance issues. These are outlined below, together with some advice as to how to overcome them.
1. Latency: this is the gap (usually given in milliseconds) between an image being captured by a webcam at one end of a transmission and that same frame being displayed at the other end. The three most common contributors to this are handling delay, propagation delay, and queueing delay. Prioritising VoIP traffic qatar telegram over the network is the key way to reduce latency. This can be done via Policy based network management, Quality of Service (QoS), bandwidth reservation, or Multi-Protocol Label Switching.
2. Jitter: this is the measure of latency variability across a network. Because the data is divided into packets, and travels on a different path, some might arrive at their destination in a slightly different order to that in which they were sent – this may cause the video quality to suffer. The easiest way to deal with this is to use jitter buffers.
3. Poor or unreliable Internet connection: the best solution for this is to use high-speed business internet.
4. Buffering: this occurs whenever a process must wait until for a certain amount of data to be available. The best ways to combat buffering issues is to use high-end video encoders which allow control of the bit rate and the averaging period.
5. Poor routers: sub-standard routers can contribute to poor quality pictures. The most obvious solution to this issue is to invest in a specialist VoIP router. These routers give priority to VoIP traffic on the network and are not prohibitively expensive.
6. Incorrect network configuration: it is important that the network is correctly configured to deal with VoIP traffic. Without this, picture quality may suffer.
