Web Real-Time Communication (WebRTC) has been interested in many developers for video conferencing. The major aim is to create a scalable WebRTC signalling mechanism called (WebNSM) for bi-directional video conferencing via Ethernet of LAN and WAN networks. WebNSM was designed for many users over star topology (one-to-many) using Socket.io (API) mechanism and various JavaScript methods to handle the default channel among peers and to gain a full duplex connection among the main broadcaster and participants. WebNSM has a novelty while it provides bi-directional video conferencing for undefined users, opens one/multiple rooms using the same server, determines room initiator, keeps a session productive even another participant leaves, joins an existing session or renegotiate new session, and does not allow unknown peer to join the session. Also, an evaluation of WebNSM, bandwidth consumption, CPU performance, memory usage, Quality of Experience (QoE), maximum links and RTP calculation was achieved. Moreover, this paper highlights the limitations of resources and using star topology for WebRTC video conferencing.
