Introduction to Video Conferencing


The Internet is designed to allow communication between clients and servers. Typically, the client initiates a request, and the server responds to it. The flow is also similar for real-time applications where users communicate with each other. However, because the request of each user relays through an intermediate server, an additional lag or delay is inevitable. When it comes to video conferencing, the flow may not be optimal, especially when the server is too far away from the user, because it can add delay and lag due to the size of the data and result in glitchy playback.
