UUnet's arguement for charging to sendis that you can potentially chew up large portions of their network bandwith with only a small connection yourself.
what else is multicast for? hopefully it works out cheaper than your expected outbound unicast streams would have cost (including the clue overhead for supporting mcast)
That is my argument. I am working on them now. However, what they hit me back with, is if you are multicasting, you can have a 10MB connection to UUnet, send a 1MB multicast stream which could be multiplied 100 times over their backbone. Thus, you can use much more than their backbone than you are paying for. However, with unicast, if you have a 10MB connection, you can't send more than 10MB with unicast. If you need more bandwidth, you buy more. My argument back, was that it is highly unlikely that I will have 100 different receivers which will have 100 different paths across their network. If their network is designed properly, there should be less impact on their network with multicast than with unicast. I hope they buy that. :-)
Very true. I am having a hard time grasping the technical specifics. It has taken quite a bit of study and discussion to figure out what I have so far, and I am sure I have misunderstood many things. Unfortunately, what I am finding out, is that multicast is a subject that rarely comes up as an option with customers. There isn't a demand, so the providers don't put the resources into it...
things don't gain momentum if they keep changing direction.
<sotto-voce>the same might be said to the v6 folks</sotto-voce>
Changing direction or improving? Many of the original problems with multicast are being addressed and improved upon with newer RFC's and protocols. At least, that is my understanding... I am new to multicast, so that may just be the marketing drivel that I have stumbled onto. :-) === Tim ********************************************** Tim Winders, MCSE, CNE, CCNA Associate Dean of Information Technology South Plains College Levelland, TX 79336 Phone: 806-894-9611 x 2369 FAX: 806-894-1549 Email: TWinders@SPC.cc.tx.us ********************************************** -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (OSF1) Comment: Made with pgp4pine 1.76 iEYEARECAAYFAjsjhakACgkQTPuHnIooYbwwpQCfZxkW8C52RkZaL8TD/T5WtTrJ mhYAoKE60sk2ihik9dJ4FGPG9R3+p7Nx =/COK -----END PGP SIGNATURE-----
