Multimedia Electronic Mail: Standards and Performance Simulation
Abstract
This thesis surveys the current multimedia electronic mail (e-mail) related standards. The increasing demands for interoperability pushed the international standardization organizations to develop standards for e-mail. The multimedia e-mail related standards include X.400 and ODA. ODA supports formatted text, raster graphics, and geometric graphics. The future standards will be able to support high bandwidth uses such as high-resolution color still-image, full-motion video, voice, and audio. The future components of multimedia e-mail include TIFF for raster graphics, CGM for geometric graphics, JPEG for high resolution color still-image, and MPEG for full-motion video. These multimedia data require vast amounts of storage, processing time, and transmission bandwidth. The standardization efforts can be viewed as selecting the best combination of these three factors, interoperability, and timing consideration. According to this view, the standard for each component is reviewed with frame of background, coding, compression, and current status. With the information from the survey study, a simulation study is conducted to investigate the performance of LAN where multimedia data are transmitted. The simulation results show that the high resolution image browsing activity in a LAN will burden the low speed LANs. The adoption of compression chips or high speed LANs such as FDDI will make such high bandwidth activities feasible.
