The paper proposes a measurement on-demand (MoD) service over the Internet, which allows accessing, streaming and delivery of archived process acquisition data. A client accesses to the service for the purpose of receiving previously stored process acquisition data under the form of media streams. Media streams are captured, on the receiver site, by using multimedia-based distributed Virtual Instruments (mDVIs). MDVIs are virtual instruments split into possibly multiple and independent parts, sender and receiver, which are linked by real-time continuous media streams. A media measurement stream consists of time-stamped packets containing the sampled data in the payload field according to the real time transport protocol. The interaction between a MoD server and a client is based on an enhanced version of the Real Time Streaming Protocol suited to measurement. The service has been prototyped in Java2 and run on a local networked environment
