DRT: A Deterministic Computing and Network Resources Tradeoff Mechanism for Holographic-Type Communication

With the emergence of the 6th Generation (6G) and the Metaverse, holographic-type communication (HTC) has become a crucial aspect of future communication. While the HTC system can deliver an immersive experience, it demands stringent real-time processing, substantial computing resources, and high bandwidth. However, current HTC systems struggle with ensuring ultra-low latency and finding a tradeoff between network and computing resources. In this paper, we introduce the Deterministic Computing and Network Resources Tradeoff mechanism (DRT). This mechanism ensures bounded MTP latency by implementing traffic shaping mechanisms and modeling computing latency. Additionally, we propose a routing and scheduling algorithm based on the constraints of DRT, which efficiently allocates network and computing resources, thereby minimizing MTP latency for users. Experimental results demonstrate that DRT ensures minimum MTP latency compared to other mechanisms, with the lowest recorded MTP latency at 34.78 ms, approximately three times lower than cases without DRT.
