We are looking to deploy a new WAP Gateway in our network, to replace the existing one which is falling over regularly.
Hi Stuart, please let me answer you questions inlined below:
I have a few questions: Is the WAP Kannel gateway in use commercially in many networks?
the normal Kannel WAP gateway, means the WAP 1.2.1 parts are "officially" not running in any live MNO networks. We have informations that some Latin American and Asian networks have it as a kind of "fallback" for their main commercial vendors.
Beside the normal Kannel, there are a numerous set of Kannel-CG installation at MNOs and MVNOs. The commercial Kanenl-CG (carier-grade) WAP gateway that we provide is a full featured WAP 1.2.1 and WAP 2.0 gateway, including a full featured RADIUS server and on-the-fly byte accounting server.
We are proud that Kannel-CG has been substituting several major commercial vendor installations, including deployments from Huawei, Ericsson, Openwave and Acision - by outperforming all of these vendors in terms of maximum concurrency performance.
Does it support all of or most of the last WAP protocol?
The open source Kannel does support WAP 1.2.1. Though, there are some "flaws" in the WAP 1.2.1 stack, especially when used under high concurrency load. This was the main reason we have re-written the WAP 1.2.1 stack with more effective data structures and releasing this in combination with WAP 2.0 (HTTP proxy capability) support into the commercial Kannel-CG product.
Would it be capable of approximately 70 Transactions per second WAP Pulls?
Should, that's not a huge amount of concurrent traffic. I don't have any hard figures for the open source Kannel WAP part, the Kannel-CG installations handle from 800 to 2400 TPS concurrently, depending on hardware and architecture layout.
What Hardware would be recommended to support that level of throughput?
The 70 TPS should be working out-of-the-box for any normal production class machine of today. Having a nice amount of RAM is always welcome, but not necessary.
Thanks for any help that can be given.
you're absolutely welcome. Please let me know if I can assist you any further, either with the open source Kannel parts for the WAP 1.2.1 or even with the commercial Kannel-CG WAP Gateway.
