Hi ,

There are 2 protocols X and Y. X runs over UDP. Y runs over X. A payload packet consists some headers of X and some headers of Y.

I am dissecting Y, and X  has been dissected by somebody else , who do not wish to share the source code.

As per my understanding:

1. There should be an identification number which identifies Y over X.
2. There should be sufficient bit-wise information in Y which identify X headers and data .

But I did not get either of the information. Instead I have a document which describe some headers of Y which contain X data , without specifying the values.

I am not able to understand how can I integrate the other protocol with mine and test the complete packet containing both the headers.

BR,

Tarani
