You actually want to use multicast, not broadcast, as multicasts can go only to the machines that want them, and if you have multicast-capable routers your multicasts can cross subnets without an application-level gateway. You may want to look at the RTP spec, along with the MPEG profile, both available as Internet-Drafts from ds.internic.net:/internet-drafts : draft-ietf-avt-rtp-07.ps / draft-ietf-avt-rtp-07.txt draft-hoffman-rtp-mpeg-encap-01.txt You might have trouble if your MPEG codecs have no way to cope with loss, as for multicast applications you will need to use UDP. For such time-critical data as an MPEG stream, though, it doesn't make sense to try to be reliable; your decoder should just reset the codec at an appropriate point if it detects loss. Bill
