Abstract: Examples describe a method of operating a distribution point unit (DPU) having a wireless backhaul connection, such as a 4G or 5G connection. The distribution point unit is reverse powered electrically by connected subscriber lines. The radio configuration (number of antennas, frequencies, etc.) used by the wireless backhaul connection is switched according to the power available from the subscriber lines. Changes to the available power can trigger a switch to a new radio configuration. Higher capacities (data rates) can be achieved with higher power radio configurations, which can be switched over to if the available power is sufficient. Similarly, when the available power drops, a switch can be made to an appropriate lower powered radio configuration.

Abstract: A method of managing a network for delivering content to a client device, where content segments are delivered over multicast to a proxy. The received segments are stored at the proxy, before delivery of those segments is made from the proxy to the client device over unicast. Whilst the proxy receives further segments over multicast, it probes the network by making unicast requests for data (dummy data or additional content segments), and receiving those segments over unicast from the content server. The multicast rate reception rate and the unicast (probe) rate are measured and a maximum network throughput is calculated as the sum of these two rates. Subsequent segments are then delivered from the proxy to the client device at the calculated maximum network throughput rate, or at some rate dependent thereon.

The aim is to ensure continuous play-out of good quality segments, without relying on a large buffer, so that end-to-end delay is kept low. The historical network delivery rate is measured on two or more timescales, such as a short-term delivery rate and a long-term delivery rate, and these are used to decide when to request a higher bit rate segment than the previous segment, and when to request a lower bit rate segment than the previous segment.
