What's the URL to stream a content from CE to a PC?

[garyhuang]

I have some media files replicated on the CE and want to play the files to a PC's media player by using HTTP request on the PC. What'e the format of the URL I should put in? such as http://channel's FQDN/relative file path/file name?

The CE and the PC are in the same subnet. There's no NTA involved.

Thanks

what software version do you have ?

Since version 5.x there is no need of a specific url.

Just type the url that you would enter to get the content directly from the server.

In transparent mode, a router should intercept your request and forward to the CE.

Otherwise, configure your broser to use the CE as a proxy.

I have ACNS 5.1.7 running on CDM, CE, and CR. Are you saying just to enter the URL as to get the content directly from the origin server?

I thought the CR would redirect the request to the best CE and the content would come from that CE to the computer's browser.

Can you explain more details?

Thanks

Hi Gary,

as far as i understood this in a presentation the request will be intercepted and redirected to the CE which is closest to the requestion client.

I guess Gilles is able to add more information but I think this is the basics of what is happening.

Cheers,

Gary,

there are 3 ways to get the content.

The first 2 methods, simply uses WCCP or proxy to intercept the request from the browser to the origin server. - no need of special url.

The last methode uses the CR.

All this is explain at :

http://www.cisco.com/en/US/products/sw/conntsw/ps491/products_configuration_guide_chapter09186a00801cc611.html

See the section : Configuring a Content Engine as a Routing Content Engine

However, this is not necessary if you use the other 2 methods - much simpler.

Gilles.

Gilles:

I don't have a router here I can configure the WCCP on it and I'm not clear how to get the proxy to work. I was told by a Cisco engineer that using CR to do the hybrid routing is a good way, and that's what I'm trying to do.

Here is what I have done so far:

I have a CDM, CE, and a CR in the lab, and media files are replicated to the CE already. For example one file is stored in the CE as: /ciscomedia/mpegmedia/ice_age.mpg

I configured a channel with the following FQDN: cdn.streamingteknet.com. The FQDN has been registerd publically as a NS record and a A record too. The domain name points to the IP address of the CR.

On a PC in the same subnet as the CE, I entered the following URL on the PC to get the content from the CE: http://cdn.streamingteknet.com/ciscomedia/mpegmedia/ice_age.mpg, but have not been able to get the content to the browser.

What's your advice? Is the format correct? How should I troubleshoot?

Thanks

Gary

Gary,

what you're trying to do is simplified hybrid routing.

This is described at

http://www.cisco.com/en/US/products/sw/conntsw/ps491/products_configuration_guide_chapter09186a00801cc611.html

First question, do you have a coverage zone file ?

This is what tells the CR how to route the request.

To troubleshoot this issue, use a sniffer on the clien.

Check if it receives the right dns answer from the CR.

Make sure a request is sent to the CR and that the CR responds with a redirect.

Then check if the client opens a connection with the CE specified in the redirect.

A simple way to get the content is proxy mode as mentioned before.

In the CE configure - 'http proxy incoming 8080'

On your client browser, go in the connections configuration and seleclt LAN - proxy setting and configure the ip address of the CE and the port 8080.

Now, simply enter your http request and the browser should contact directly the CE.

On the CE do a 'sho stat http request' to see request coming in.

Regards,

Gilles.
