Hi all,
Am trying to implement a diameter application (Application-ID 16777255)
using go-diameter package.
>From what I have read, to be able to exchange message between
diameter peers, these basic steps are required
1. the transport connection (TCP/SCTP) need to be established.
2. CER/CEA message have to be exchanged between the peers after which
3. send message
4 Device-Watchdog-Request/Device-Watchdog-Answer will be sent by any peer
as some sort of health check
and if possible disconnect the connection.
Studying the go-diameter package example diameter client and server, I have
managed to modify both the client
and server to support my application by creating a custom dictionary for my
application and load them at both the client
and server code.
Apart from the client settings which advertise the
"VendorSpecificApplication" of my application ID, command code, etc,
I have also created a function "sendmessage" request which contains AVPs
corresponding to some of my application dictionary AVPs.
However, after testing the modified client and the server and using
Wireshark, the diameter message "Result code" shows "success 2001"
after CER/CEA where exchanges but after that, I could not see the
"sendmessage" messages sent from the client
even though I have created a "sendmessage" handler at the server side which
response with an answer.
The CER/CEA messages are exchanged and then DWR/DWA messages are exchanged
for the time set and then the connection disconnect.
The CER/CEA messages are implemented using the go-diameter default base
application.
Can anyone explain to me why am not seeing my application messages which I
expect to see after the CER/CEA exchange?
I may be doing something wrong.
I can send the modified code if needed.
