10. NWWS Discussion/Open Forum
1. Losing diversity in communications given SCS1 satellite data stream will be lost with the termination of the CSC contract. 
single point of failure with loss of redundancy
2. Dish size requirements; some clients have C-band dishes, some with Ku Band. 
3. Changes in message formats.  Example; Text vs "wrapping of products in SBN/NOAAPORT hdlc frames“
4. Open Interface TCP/IP vs XMPP Chat. .
As NWWS proceeds with the transition, your cooperation, collaboration, and input are appreciated. Please feel free to contact NWS for more information about the upcoming change(s) or to provide input on system capabilities and proposed distribution methods and shortfalls of the available options.
