Web Real-Time Communication (RTC) is a method of real-time communication that allows interactive communication between networked computer systems without the need for large file transfers or lengthy downloads. RTC is a transport layer that originated with Multimedia Messaging Service (MMS), which used the Internet as its delivery system. Today, RTC is an industry-standard and enables end-to-end interactive communication over wide area networks such as the Internet.
WebRTC provides several benefits compared to traditional web conferences. For example, video conferencing can be conducted while on the move, whereas in real-time conferencing the participant must stay at the location of the conference. Video conferencing also uses bandwidth and high-speed Internet connections. WebRTC can introduce real-time audio as well as video communications over the Internet, which may be transmitted to multiple participants simultaneously. It also allows real-time video conferencing through the use of webcams and other similar technology.
In a typical real-time communication session, an application called a client interacts with a server, which carries the audio and/or video signal, along with the relevant information, from one device to another. The server sends the signal to the application via an Internet connection. Web-based RTC systems can be integrated with applications such as Adobe Flash, which can create rich media applications (RMA) and run them in the browser. This feature is useful for making presentations and sharing photos. WebRTC also supports plug-ins, which enable users to conduct secure data transfers, such as encryption and authentication.
Currently, most WebRTC systems are based on the WebRTC API, which can be implemented using a variety of common computer languages including C++, Java, C#, and PHP. In addition to being an open-source technology, WebRTC provides support for the Sockets API, which allows the transport of data over the Internet using TCP/IP. WebRTC does not depend on the presence of any special hardware or networking devices. Since it operates over the Internet, it is compatible with all kinds of browsers, and is expected to be available in all platforms when WebRTC becomes operational.
Benefits of Web Real-Time Communication
WebRTC offers several benefits, such as enabling real-time communication between two or more parties that are unable to meet in real life. In addition, WebRTC makes it easier for people to take part in online seminars or conferences, since they do not have to deal with long-distance phone calls or video conferencing. It also helps them to increase their efficiency by reducing the cost of video conferencing. Without requiring plug-ins or downloads, the WebRTC implementation can be done easily. This makes it suitable for small and medium-sized businesses as well as students who want to take a quick online course or buy a product on the web without having to wait for a traditional classroom. WebRTC is also very easy to use and understand, making it popular among Internet users.
But WebRTC has some drawbacks that need to be looked into before it can be deemed a great option for enterprises. One of the biggest problems with WebRTC is that it will require an entirely new infrastructure to support it. A lot of IT experts believe that this is a big drawback since switching from an on-premise video conferencing service to a cloud-based one will cost a business hundreds of thousands of dollars. Another problem with WebRTC is that the WebRTC technology is still at an early stage of development and there are many bugs that need to be worked on. Since the technology is still in its infancy, most businesses are not ready to make the transition to the new platform.
In addition to the drawbacks mentioned above, WebRTC does have some advantages. One of the major benefits of WebRTC is that it eliminates the need for client-server authentication and allows for flexible real-time video conferencing. Another advantage is that signaling is done using the same protocol as other similar technologies. This helps reduce the bandwidth usage, which will help reduce the overall cost of WebRTC. WebRTC's packets do not contain sensitive information and are well-protected against security threats such as hackers. The API of WebRTC is based on the W3C process and as such it works very smoothly with all browsers and operating systems.
There are some limitations as far as WebRTC is concerned. In particular, WebRTC doesn't support direct signaling between two endpoints over a local area network, which means that the signaling required by video-conferencing applications is quite limited. Also, the use of IP packets in the signaling process can lead to significant delays.
