Release Notes for Cisco Internet Streamer CDS 2.2
OL-16951-02
Enhancements
3-Screen Session Shifting integrates with the delivery service configuration by linking three XML files
that interact with content management and transcoding systems to obtain device-type mappings and
content format mapping. 3-Screen Session Shifting works with entitlement servers to get the user
identification and uses the user identification as a key to store user sessions.

Enhancements
In Release 2.2, Movie Streamer and Flash Media Streaming supports H.264 streaming of prefetched
content, dynamically ingested content, and live content.
content, dynamically ingested content, and live content.
System Requirements
The CDS Internet Streaming runs on the CDE100 and CDE200 hardware models. The CDE100 may run
as the CDSM, while the CDE200 may run as the Service Router or the Service Engine. See the Cisco
Content Delivery Engine CDE100/200/300/400 Hardware Installation Guide for set up and installation
procedures.
as the CDSM, while the CDE200 may run as the Service Router or the Service Engine. See the Cisco
Content Delivery Engine CDE100/200/300/400 Hardware Installation Guide for set up and installation
procedures.
Limitations and Restrictions
This release contains the following limitations and restrictions:
•
There is no NAT separating the CDEs from one another.
•
Do not run the CDE with the cover off. This disrupts the fan air flow and causes overheating.
Important Notes
To maximize the content delivery performance of a CDE200, we recommend you do the following:
1.
Use port channel for all client-facing traffic.
Configure interfaces number 3, 4, 5, and 6 (those on the quad-port Gigabit Ethernet Card) into a
single port-bonding interface. Use this bonding channel, which provides instantaneous failover
between ports, for all client-facing traffic. Use interfaces number 1 and 2 (the two on-board Ethernet
ports) for intra-CDS traffic, such as management traffic, and configure these two interfaces either
as standby or port-channel mode. Refer to the Cisco Internet Streamer CDS 2.0-2.1 Software
Configuration Guide for detailed instruction.

2.
Use the client IP address as the load balancing algorithm.
Assuming ether-channel (also known as port-channel) is used between the upstream router/switch
and the SE for streaming real-time data, the ether-channel load balance algorithms on the upstream
switch/router and the SE should be configured as "Src-ip" and "Destination IP" respectively. Using
this configuration ensures session stickiness and general balanced load distribution based on clients’
IP addresses. Also, distribute your client IP address space across multiple subnets so that the load
balancing algorithm is effective in spreading the traffic among multiple ports.

Tune the TCP parameter.
On the CDE200, execute the following commands once (This tunes the internal TCP configuration
for better content delivery performance over HTTP.):
