Cisco Cisco Content Acquirer Application Release Notes

Release 3.1.0 of the Cisco Internet Streamer CDS introduces the Wholesale CDN feature.

Multicast Cloud is an early field trial (EFT) feature. For more information, contact your Cisco account 
representative.

The Wholesale CDN feature offers the ability to configure delivery services with quotas and send 
real-time information to the Content Delivery Network Manager (CDNM) for managing wholesale 
(business-to-business) accounts. 

The Wholesale CDN feature provides the following functions:

Setting session and bandwidth quotas per delivery service in the CDS, and associating a delivery service 
with a content provider (tenant) in the CDNM, provides the ability to manage multiple tenants with 
different session and bandwidth requirements in the CDNM.

The per-delivery service session quota limits the maximum number of concurrent sessions for that 
delivery service. The per-delivery service bandwidth quota limits the maximum bandwidth used to 
deliver content to clients.

The Service Router (SR) enforces the maximum limits (session quota and bandwidth quota) and tracks 
usage on each Service Engine (SE). The usage data is aggregated across the delivery service. The SR 
makes session enforcement decisions upon receiving requests to load balance. If the request for content 
does not exceed the maximum limit (quota threshold), it is routed to the best SE in the delivery service. 
If the request for content exceeds the maximum limit, the client receives an appropriate error response. 

The session and bandwidth quotas do not reserve resources, nor do they guarantee service. The quotas 
only limit the maximum usage of a delivery service.

Release 3.1.0 only supports session and bandwidth quotas for Web Engine progressive download, Web 
Engine adaptive bit rate (ABR), and Windows Media Streaming. Session and bandwidth quotas are not 
supported for Flash Media Streaming and Movie Streamer.
