Hello Nanog,
We are developing a streaming video based application. Can someone tell me whether
(1) Multicasting is necessary for such an application (2) How do we configure multicasting, and multicast (224.x.x.x) to Global IP Conversion, on Cisco Routers. Some useful sites will be handy. (3) What is the function of the MBone network, and whether it is required for such a situation.

Hello; The old MBone - the set of DVMRP domains connected by tunnels, is nearly dead - it shows up as AS10888. The native multicast enabled mbone is called by some the MBone, but this usage is not universal. At any rate, from Sri Lanka you may have trouble getting a direct connection to the multicast enabled Internet. I recommend Sprint in general as the most cluefull of the large multicast providers. I do not know where or with whom you peer, but possible "nearby" multicast service providers include AS 2497 Internet Inititative Japan Inc. AS 9270 Korea Telecom AS 9589 UUNET Hong Kong Ltd. I cannot speak as to their ability. Also, Enron or Qwest might be able to help. If you want to get up quickly, unless you directly peer with someone who does multicast, you will need a tunnel to someone who does. We could help you with that... As Golding says, you will need to speak MSDP and MBGP, as well as (strongly recommended) PIM-SM and IGMP internally Cisco documentation can be obtained from ftp://ftpeng.cisco.com/ipmulticast.html and http://www.ieng.com/warp/public/cc/techno/protocol/ipmu/tech/ipcas_dg.htm Also, you should read the info in http://www.live.com/mbone/ and http://www.ietf.org/meetings/get-mbone.html Further info is available from http://www.ipmulticast.com/ - you should think about joining the IP Multicast mailing list, which is more appropriate for multicast questions than NANOG - To subscribe to the IP Multicast mailing list, send an email message to listserv@stardust.com Leave the subject blank, place the following line of text in the body: subscribe ipmulticast <your full name> Regards Marshall Eubanks Multicast Technologies, Inc. 10301 Democracy Lane, Suite 201 Fairfax, Virginia 22030 Phone : 703-293-9624 Fax : 703-293-9609 e-mail : tme@on-the-i.com http://www.on-the-i.com
