Abstract
Medical network traffic is characterized by the mix of modalities and applications on the network. Since different modalities or applications have different characteristics on the network, understanding the mix of traffic loads is important in analyzing network activity. Although many commercial products can analyze network traffic at the packet level, they do not capture higher level modality load characteristics or isolate the impact of large image transfers. More insight can be obtained through a high-level analysis of this packet data in which network traffic is examined at an application level. In this paper we report on data collection and analysis of medical network traffic over a local area network. The measurements of the LAN are made using a raw ethernet packet capture program (tcpdump) running on a Sun workstation, and the analysis was accomplished using a PERL script and the ACE/gr data analysis program. The contribution of each modality is isolated and the network protocol performance is examined in detail.
