    How to limit the size of the parameters of the method.I wrote a method in the main.asc then the client NetConnection.call assignment, but if the client is malicious to upload very large data, how to limit it, I view the document did not find the clues, I hope that those parameters up to100KB.

    TIll i do more investigation - i can say you can make sure only your authentic SWF connect to your FMS by using feature like SWFVerification - this does not rule out the attack but at least minimises it - i am also expecting you to have some check on client-side so that you don't allow any size for your parameters - do client side check first. Also have more security measures like authentication so that you allow only authentic and validated users to join in.
