Abstract |
Computer Network is much more important for data communication in healthcare and medical informatics field. Designing in hospital network is not simplified because Information Technology is sharply developed. Traffic analysis is one of major’s factors for the network design. In recently, characteristic of HTTP, FTP, SMTP, VoIP and other Internet applications are widely studied. However, a characteristic of PACS traffic that is a popular medical imaging is rarely studied. Therefore, this paper presents PACS traffic analysis in an intra-domain network. The traditional traffic analyst often represents results in terms of bandwidth such as bandwidth utilization. In contrast, PACS traffic analysis in this paper is based on a term of delay since a constraint of PACS communication is defined as the desirability that one-way direction of each picture should be displayed on a viewing workstations screen within 5 seconds. From some experiments, a relationship between a duration time and packet arrival rate (pps) is presented. In addition, relationships among the bandwidth connection, the duration time of PACS flow, and the packet arrival rate (pps). PACS image size and ping delay time are also presented. |
