Performance analysis on network transmission for an ARM-based embedded Linux system
Yichao Ma · Nuclear Techniques · 2010
Multi-level trigger architecture is commonly used in data acquisition systems for large scale high energy physics experiments.In multi-level architecture,data is sent to higher level systems through network,which is usually based on Ethernet technology.In order to improve system efficiency and find out optimization methods for data transmission,in this paper we describe the network data receiving process of Linux 2.4 kernel in terms of data flow that based on ARM platform,and combined with the data obtained from the kernel.Reasons of changing network performance are analyzed,too,and system optimization recommendations are given.
