A novel packet-based adaptive mechanism for bounding delay and delay variation in 5G Ethernet fronthaul is proposed. The mechanism enables aggregation of asynchronous traffic from fronthaul links using a traffic pattern adaptation algorithm. Traffic of a first stream is added in time-gaps of a second stream. For bounding and balancing the packet delay and delay variation between the streams, the size of the required time-gap before insertion is made adaptive. Simulation results demonstrate that through suitable tuning of the algorithm parameters, packet delay and delay variation below 10 microseconds can be achieved.

Abstract
A novel packet-based adaptive mechanism for bounding delay and delay variation in 5G Ethernet fronthaul is proposed. The mechanism enables aggregation of asynchronous traffic from fronthaul links using a traffic pattern adaptation algorithm. Traffic of a first stream is added in time-gaps of a second stream. For bounding and balancing the packet delay and delay variation between the streams, the size of the required time-gap before insertion is made adaptive. Simulation results demonstrate that through suitable tuning of the algorithm parameters, packet delay and delay variation below 10 microseconds can be achieved.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
