Among various layer three block codes, Random Linear Network Coding (RLNC) has emerged as an adaptable, powerful approach. However, its most straight-forward implementation, Full Vector Coding (FVC), introduces too much delay for widespread adoption. Handcrafted schemes were introduced to optimise coding delay, while keeping resilience reasonably high. These works have resulted in tailRLNC and PACE. For the first time we analyse their respective behaviours in a fair and comparable manner, as non-recovered packets were statistically ignored previously. We then introduce an environment that uses a consistent, unbiased simulator and interface it with a Deep Reinforcement Learning (DRL) agent. This is the first time RLNC is joined with DRL. Our deep Q-network (DQN) based agent effectively uses an optimisation loop and utilises a customisable, expressive and extendable parametric loss function to learn a protocol. We demonstrate our agent recovers hand-tailored schemes and achieves state of the art.}, note = {accepted for publication}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

Comparison of UPF acceleration technologies and their tail-latency for URLLC Proceedings Article

The envisioned use cases, such as industrial automation, require Ultra-Reliable and Low-Latency Communications (URLLC). In 5G, the User Plane Function (UPF) handles user traffic and hence significantly influences the performance in terms of latency and throughput. However, present UPFs are often user-space applications running on commercial off-the-shelf (COTS) servers introducing computational delays that follow long-tailed distributions. In this work, we compare modern packet processing acceleration technologies such as XDP, DPDK, and P4 and their respective tail-latency performance. Our results demonstrate the clear advantage of hardware-based P4 implementations in terms of reduced tail-latency of about 6 μs at a percentile of 99.999% for small packets. Furthermore, we also demonstrate that software-based frameworks can compete with hardware-based approaches. For example, DPDK achieves tail-latencies of approximately 23 μs at a percentile of 99.999%. Based on our findings, we illustrate the trade-offs between low-cost software- and high-performant hardware-based packet processing systems.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }
