 The Data Channel API enables real-time messaging during audio and video calls. With this API, you can now easily integrate chat and data exchange functionalities into the applications, providing a seamless communication experience for users. Key features include:
 
-1. Real-time Messaging: The Data Channel API enables users to instantly send and receive messages during an ongoing audio or video call, promoting smooth and efficient communication. In group call scenarios, messages can be sent to a single participant, a specific set of participants, or all participants within the call. This flexibility enhances communication and collaboration among users during group interactions.
-2. Unidirectional Communication: Unlike bidirectional communication, the Data Channel API is designed for unidirectional communication. It employs distinct objects for sending and receiving messages: the DataChannelSender object for sending and the DataChannelReceiver object for receiving. This separation simplifies message management in group calls, leading to a more streamlined user experience.
-3. Binary Data Support: The API supports the sending and receiving of binary data, permitting the exchange of diverse data types, such as text, images, and files. Note that text messages must be serialized into a byte buffer before they can be transmitted.
-4. Sender Options: The Data Channel API provides three configurable options when creating a sender object, including Reliability, Priority, and Bitrate. These options enable the configuration of a channel to meet specific needs for different use cases.
-5. Security: All messages exchanged between a client and the other endpoint are encrypted, ensuring the privacy and security of users' data.

 ### Rate limiting
 There's a limit on the overall send bitrate, currently set at 500 Kbps.
 However, when broadcasting messages, the send bitrate limit is dynamic and depends on the receive bitrate.
-In the current implementation, the send bitrate limit is calculted as the maximum send bitrate (500 Kbps) minus 80% of the receive bitrate.

 Furthermore, we also enforce a packet rate restriction when sending broadcast messages.
 The current limit is set at 80 packets per second, where every 1200 bytes in a message is counted as one packet.
