Mark and Vadiraj,

A post on the second scenario - Multicast edge server sourcing from a unicast broadcast on an origin server - is coming soon. Stay tuned!

Hi, Nick,

If the multicast coming in at the remote office is a Windows Media multicast, then you can capture it there with a Windows Media server using the steps described in my post (above) for sourcing from a multicast at an Edge Server, and then unicast it to your main office WMS server. In your scenario, the map is just laid out in reverse order.

In the main office, you would set up WMS to source from the unicast stream coming from the edge, then stream it out as a multicast. That will be the topic of another blog post, coming soon.

Hi Chris

Any chance you can address the 2nd scenario you mention: Multicast edge server sourcing from a unicast broadcast on an origin server ?

My VPN doesn't support multicast but my LANs are single subnet so they should. I would like the LAN servers to source over unicast from my central WMS server, but multicast to local clients.

Thanks

Mark

I have a multicast stream injected into my Network that I want to capture using Windows Media Encoder or another video compression tool at a branch office, push to my Windows Media Server at my Main Office and then multicast out to all remote offices via my WMS.

Any suggestions on a Media Encoder Tool that'll support this endocing on a stand alone computer?

Best Wishes

Ooopppss,

Meant to tell you I have it already running in unicast mode, just can't convert it to multicast.

Chris, I appreciate the info you have posted, I am trying to set up a multicasting server, but I run into problems getting the encoder to work right, I get errors about format problems, I get the encoder running off of port 8081, I then try to link the windows media server to it & get the format errors then.

any help will be appreciated.

Hi, Boris,

A few thoughts come to mind:

1. Your network routers must be multicast-enabled, meaning that they can transmit class-D IP addresses, or you are only delivering multicast stream over the local segment of your local area network.

2. Any firewalls between your server and your clients must allow multicast traffic to pass through: www.microsoft.com/.../firewall.aspx.

3. In Windows Media Player, you need to ensure the multicast protocol is enabled (for a larger deployment, this can be set using Group Policy). To configure protocol settings manually:

a. In Windows Media Player, on the Tools menu, click Options.

b. In the Options dialog box, on the Network tab, in the Streaming protocols area, ensure the multicast protocol check box is checked.

4. You will need to point the Player to a multicast information file (with an .nsc file name extension) directly, or within the context of an announcement file (with an .asx file name extension). These are typically located on a file share or Web site.

Here are a couple of Cisco-related resources that might help:

1. An easy-to-understand (and somewhat older) overview of how Windows Media fits into Cisco networks: www.liamkeegan.com/.../cdn-multicast.html

2. If you are also using Cisco ACNS in your network: www.cisco.com/.../networking_solutions_white_paper09186a00801f46a9.shtml

I hope this helps!

HI,

any help is appreciated.

Thanks,
