In this paper, we describe the webcast implementation details and data collection during a multicast session of a technical conference held in Vancouver in Summer 2001. Audio and video signals were multicast using Internet Multicast Backbone (MBone) multimedia conferencing tools. The signals were transmitted to the MBone network using DVMRP tunneling through an ADSL line to the BCnet gigabit-capacity point of presence. Genuine traffic traces were collected during the multicast session and were later used to analyze the impact of traffic on network performance.
