Dynamic bandwidth re-allocation

摘要

A method and system for dynamic bandwidth re-allocation is provided. The method includes the steps of monitoring a video streams delivered by a server to a first client and a second client that have a same service level agreement and determining whether the first client is receiving a lower bitrate video stream compared to the second client. The method further includes the step of adjusting a parameter to allow the first client to receive a higher bitrate video stream. In an example, the monitoring, determining and adjusting steps are performed by a cable modem termination system (CMTS). In another example, the monitoring, determining and adjusting steps are performed by an optical line terminal (OLT).

主权项

1. A cable modem termination system (CMTS), comprising:
a video flow monitoring and marking system that is configured to:
monitor video streams delivered by a server to a first client and a second client, wherein the first client and the second client have a same service level agreement; determine whether the first client is receiving a lower bitrate video stream compared to the second client; and adjust a parameter to allow the first client to receive a higher bitrate video stream; and a downstream physical layer modulator coupled to the video flow monitoring and marking system, and configured to transmit video streams received from the server to the first and second clients, wherein the video flow monitoring and marking system is further configured to adjust a parameter in a downstream service flow extended header to assign higher priority to the video stream delivered to the first client.
