From dcrider at ket.org Wed Dec 5 00:48:36 2007 From: dcrider at ket.org (David Crider) Date: Tue, 04 Dec 2007 18:48:36 -0500 Subject: [Udpcast] throttle output of udp-cast Message-ID: <4755E754.6090701@ket.org> Is it possible to do dynamically throttled UPDcast transmission? We need to throttle the data flow to a Logic Innovations IP encapsulator (with LI's documentation attached with their permission). The udpcast mutlticast address is considered a single route to the IPE. The IPE sends out flow-control messages (described in document) that shows how many bytes are available for traffic for each route every 100 milliseconds in a multicastand comes from a user specified multicast of its own. Attached is the LI document, again with the manufactures permission. Also, you can contact Theo Aukerman, taukerman at logici.com for any additional info. I'm asking these questions because IF this is possible, then this would be an almost complete framework for an open source Data-casting network, and can be used for over the air data-broadcasting from any DTV transmitter or any other system with null packets. I currently work as an engineer for a TV station that does data transmission, but would like to move to an open source model. -------------- next part -------------- A non-text attachment was scrubbed...

Now, the boot system tries all network interfaces (except loopback) until it finds one where it can get an address via DHCP.
