The limitation in maximum packet size of fieldbuses, is one of the characteristics that limit throughput in these networks. This restricts the range of multimedia applications viable over these infrastructures. In Ethernet, the limitation of 1500 bytes is currently being surpassed by the use of jumbo-frames, which offer a maximum frame size of 9 Kb, thus significantly improving the throughput of Ethernet. The aim of this paper is to analyze the impact of increasing frame size in traditional fieldbuses and in Ethernet, as they have a different range of multimedia applications. As typical multimedia applications in industrial environment, computer vision applications are analyzed.
