CDN Selector
The CDN Selector provides a method of performing third-party streaming service selection. The 
third-party streaming service is selected based on the content type of the client request, the geographic 
location of the client request, or both. When CDN Selector is enabled, the Service Router uses the 
information in the CDN Selector file to determine which third-party streaming service is selected for 
servicing the client’s request. 
Note
CDN Selector is an EFT feature for Release 2.5.7.
A CDN Selector file is an XML file containing the URL, including the directory path, of each third-party 
streaming service, and the content types and geographic locations criteria for redirecting client requests. 
If the geographic location is used as the selection criteria, the CDN Selector uses the Geo-Location 
server to map the client’s IP address to the client’s country. 
The Service Router then sends a 302 redirect to the client with the translated URL for the selected 
third-party streaming service. If the Internet Streamer CDS is chosen, the request is handed over to the 
Request Routing Engine for further processing. If the client request does not meet any of the selection 
polices criteria and a default CDN is specified in the CDN Selector file, the client request is redirected 
to the default CDN.
Proximity Engine
The Proximity Engine has the following new features:
Service Routing Protocol (SRP)
BGP best path and redirect proximity
IS-IS authentication
Proximity statistics displayed in CDSM
Multi-Port Support
Multi-port support allows the configuration of multiple interfaces, each with a different IP address, all 
used for streaming traffic. An interface could be a gigabit Ethernet channel, a port channel, or a standby 
group. Multi-port support allows for utilization of the total bandwidth available on the CDE220-2S3i and 
is introduced solely to support the CDE220-2S3i platform in order to use all 12 gigabit Ethernet 
interfaces.
