WebRTC Prioritization
The webRTC prioritization feature prioritizes the media traffic from webRTC sources. WebRTC is an open framework for the web that enables real time communication using a web browser. WebRTC includes the fundamental building blocks for high-quality communication on the web like network, audio, and video components that are used in voice, video, and chat applications.
WebRTC prioritization provides better end user experience, dashboard visibility of all WebRTC applications like voice, video, and application sharing, and call quality monitoring for audio calls using upstream and downstream RTP Real-Time Transport Protocol. RTP is a network protocol used for delivering audio and video over IP networks. analysis. Enable DPI Deep Packet Inspection. DPI is an advanced method of network packet filtering that is used for inspecting data packets exchanged between the devices and systems over a network. DPI functions at the Application layer of the Open Systems Interconnection (OSI) reference model and enables users to identify, categorize, track, reroute, or stop packets passing through a network. before enabling WebRTC prioritization.

WebRTC Prioritization Configuration
You can configure webRTC by using the CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions.. The following commands enable webRTC on the Mobility Master using the CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions.:
(host) [mm] (config) #ucc webrtc
(host) [mm] (WebRTC ALG Configuration) #enable

WebRTC Media Classification Support in Mobility Master
By default, all the VoIP Voice over IP. VoIP allows transmission of voice and multimedia content over an IP network. traffic undergo media classification on the managed device whenever RTP Real-Time Transport Protocol. RTP is a network protocol used for delivering audio and video over IP networks. Traffic reaches the managed device. The process in the Mobility Master can identify and prioritize calls made using webRTC ALG Application Layer Gateway. ALG is a security component that manages application layer protocols such as SIP, FTP and so on. . The process also provides visibility for all voice calls made using the webRTC ALG Application Layer Gateway. ALG is a security component that manages application layer protocols such as SIP, FTP and so on. . The process in the Mobility Master dynamically opens firewall Firewall is a network security system used for preventing unauthorized access to or from a private network. ports for voice and video traffic. You do not have to explicitly define a firewall Firewall is a network security system used for preventing unauthorized access to or from a private network. policy to permit such traffic.
WebRTC Media Flow Pattern
Following is the webRTC media flow pattern:
1. For any webRTC based call, there is STUN/TURN message exchanged between the webRTC endpoints.
2. The same endpoints (IP5 tuple) is used for Datagram Transport Layer Security (DTLS Datagram Transport Layer Security. DTLS communications protocol provides communications security for datagram protocols. ) packet exchange to derive the encryption/decryption keys.
3. The same endpoints (IP5 tuple) is subsequently used for Secure RTP Real-Time Transport Protocol. RTP is a network protocol used for delivering audio and video over IP networks. (SRTP) packets for exchanging media.
4. The SRTP header has stream and codec details which helps in identifying the media type such as voice and video.
