The computing models for HEP experiments are becoming ever more globally distributed and grid-based, both for technical reasons (e.g., to place computational and data resources near each other and the demand) and for strategic reasons (e.g., to leverage technology investments). To support such computing models, the network and end systems (computing and storage) face unprecedented challenges. In this paper, the Linux system's packet receive process is studied from NIC to application. The authors develop a mathematical model to characterize the Linux packet receive process. Key factors that affect Linux systems' network performance are analyzed.
