Augmenting eXtended Reality (XR) Performance Through Gated Bandwidth Allocation in EPON

Future mobile networks need to meet increasingly low latency requirements as envisaged in next-generation 6G networks. This will allow for applications like eXtended Reality (XR) that require both extreme data rates and ultra-low la-tencies. XR has recently invoked a good amount of interest in academia and industry involved in 5G and beyond (B5G). In this paper, we use the IPACT technique to examine the average packet delay using an ethernet-based passive optical network (EPON) with gated service discipline for bandwidth allocation to improve the quality of service (QoS) for XR applications. We achieved significant reduction in latency by transmitting “REPORT” message at the end of an upstream (US) transmission for a good number of optical network units (ONUs) in the PON system. We have employed the XR traffic model as specified in the 3GPP specifications. We have simulated a system with 16 ONUs to see how the PON system impacts XR services' quality of experience (QoE). With the help of this study, we were able to determine the maximum number of XR devices that the suggested technique can handle within the given delay bound.
