In response to detecting a failure of a macro network device to establish a network connection with a network device, a dynamic management of the data set initiates. A capacity number of network connections is determined for the macro network device (e.g., macro eNB sector carrier) based on the data set of neighbor relations. A threshold number is determined from the network neighbor device data, representing the set of micro network devices with which the macro network device is operable to establish the network. A defined number of micro network devices is maintained that is less than the threshold number of the network neighbor device data. |

Buffer reduction using frame dropping
The techniques described herein may, for example, allow a quantity of buffered video frames to be reduced, for example for use in adaptive bitrate (ABR) streaming and other streaming transmissions.
