WAAS - Video / Voice accelerator

dtran

Level 6

Hi all,

I have a WAAS network running WAAS 4.3.1. Today I am only using WAAS for data traffic acceleration and I am looking into leveraging WAAS for video and voice traffic optimization if that can be done and I have a few questions. I am running a Cisco VoIP and Tandberg video conferencing environment and I would like to find out if WAAS can be used to optimize and save bandwidth on voice / video calls going across the WAN.

- Has anyone using WAAS for voice / video traffic ? Please share your experiene !!!

- Is there any additional license on the WAAS box that I need to get to enable WAAS for voice and video traffic ? currently I have the Enterprice license enabled.

Thanks in advance !!!

D.

Hi D,

About the Voice acceleration, VoIP control is and should be in pass thru as per the default policies in the device.

About Video, you certanly can accelerate video traffic. You will need additional license for Video.

Hi D,

I personally never verified this but wanted to share my experience that WAAS Video AO provides stream-splitting for Windows RTSP live streaming. Thus a single live stream can be requested across the WAN for many viewers at the remote site, thus saving BW. The WAE will also perform what is known a roll-over when the remote client makes a request for RTSP/UDP to change to RTSP/TCP. This allows WAAS to perform the Stream Splitting since WAAS only operates on TCP flows. In some cases, it simply denies the player's request to start an RTSP UDP stream.  That causes the player to "roll over" to the next available protocol which is usually TCP, and to request a stream using that protocol. 

Hope this helps.

Regards.

Hi Bhavin and thanks for helping me out.

Thanks again
