What isnrt-VBR

NRT-VBR or non-real-time variable bit rate is a service category for transmitting data that doesn’t require time synchronization between the source and destination. It is used for carrying variable bit rate traffic that needs assured bandwidth or latency. NRT-VBR is a part of the Asynchronous Transfer Mode (ATM) network and hence used extensively for IP-based voice and video transmission.

Benefits of nrt-VBR

One of the significant advantages of nrt-VBR is that it is used in applications that don’t require the continuous transmission of data. It enables traffic sources to access more bandwidth when available and reduces the need for excess buffer space. With its capability to guarantee the bandwidth or latency, non-real time data transmission becomes reliable and convenient for applications such as voice or video conferencing, online gaming, and streaming services.

FAQs

What is the difference between nrt-VBR and rt-VBR?

rt-VBR is used for real-time applications such as voice and video transmission that require a synchronous flow of data, whereas nrt-VBR is designed for non-real-time traffic that has time intervals between data packets.

Which applications use nrt-VBR?

nrt-VBR is extensively used for IP-based voice and video transmission applications, online gaming, and streaming services.

Conclusion

Non-real time variable bit rate or nrt-VBR is a service category used in the Asynchronous Transfer Mode (ATM) network that provides assured bandwidth or latency for variable bit rate traffic. It is an ideal option for applications that don’t require the synchronous flow of data, and their intervals have little impact on the quality of service.
