An efficient cross-layer buffer management optimization scheme for 5 G protocol stack
文献摘要：
It is extremely challenging for the 5G User Equipment (UE) to meet the requirement of low-la- tency data transmission with higher achievable data rates. And user plane processing of 5G protocol stack ( PS) is one of the dominating components for end-to-end data transmission in the network sys- tem. In this paper, a cross-layer buffer management scheme ( CLBM) is proposed. CLBM adopts a zero-copy technique for protocol data unit ( PDU) processing between protocol layers and allows to improve the memory operation efficiency significantly with reduced processing latency and CPU us- age. Moreover, the PS performance profiling ( PSperf) tool, a general evaluation framework for the performance measurement and analysis of PS, is implemented based on the OpenAirInterface ( OAI) 5G platform. The evaluation result shows that compared with the PS of OAI the CLBM strategy re- duces the CPU usage of RLC, PDCP, and MAC layer processing significantly up to 20. 6％, 63. 4％, and 38. 8％, respectively. In result, the processing delay of the whole user plane of PS al-so has been reduced distinctly at various offered traffic load.
