Hi All, This is somewhat off-topic, but I'm interested in hearing about how people are using Kannel in large-scale deployments. Particularly, if you are using Kannel with multiple operators for large amounts of your own traffic or as a gateway for others' traffic. By "large amounts", I mean at least a few million to tens of millions of messages per day. Specifically: - What does your network topology look like? - How many and what type of machines do you dedicate to each operator connection? - How do you handle failover? What software do you use for failover? What are the pros/cons? - Do you use an external HTTP server to throttle/offset load on the sendsms interface to the smsbox? Why did you chose to do that? What are the pros/cons? - Are your operator connections always secured via VPN? What VPN software are you using? What are the pros/cons? - Are there problems you have experienced using Kannel under very high load? - What support software have you created to help you manage your deployment of Kannel? - Is the in-memory or mysql external delivery report storage mechanism sufficient, or have you implemented a more performant/robust solution? - How much NOC and engineering staff are dedicated to maintaining Kannel? Basically, I'm hoping this would be a good forum for some of the high-volume users of Kannel to share their knowledge (war stories) with the rest of us. Thanks! Garth
