understand multicasting from the client/host perspective .

Trying to understand multicasting from the client/host perspective ..

What client software is needed?
What configurations are required?
Is there web based client, and any configuraton required?
How a client start using a typical multicast service?
How does a client/host works behind the scene to get multicast service,
in conjunction with what have been set up on the router and switch?

Any good reference on this, I mean from client/host perspective, or
something that provide the"whole" picture, including protocol, router,
switch, and client/host?

A TCP/IP stack.

If the multicasts need to be sent to multiple LANs, you need
multicast-enabled routers.

Client for what? Multicasting is a general-purpose mechanism, not a
single application.

If it's transmitting, it just sends messages to the multicast address.
Multicast routers take care of sending to all the members of the group.

If it's receiving, it "joins" the multicast address. This involves
sending out a message that the local router receives, so that it can
inform other multicast routers that there's a member on this LAN and
they'll forward messages here.

Do a google search for multicast routing protocols.

Thanks Barry .. however I'd like to see something like a user
guide/experience.

Treat me like a 4th grader who needs to use this technology to attend a
Global Future Leaders Conference, what should I do? I'm using an XP
machine.

A "user guide" implies a particular application, not a general
technology. Your question is like asking for a user guide for TCP/IP,
as opposed to Internet Explorer.

Thanks..but I guess you really don't know the technology really well,
otherwise you would be able to tell a 4th grader how to use this
technology and attend the conference. :-)
