When you're running within the routing layer, you can obviously use the BundlePayload class API to fill in the bundle, which has no hard size constraints, but will itself keep bundle data in the file. Applications can use bigger bundles of course but then they need to use the file-based mechanism for passing bundles to and from the daemon. I've been mulling over this issue for a while and am leaning towards maybe changing dtn_recv to be able to return the payload in chunks for the case where the user wants it in memory. That would make the api a bit easier to use I think. -mike On May 1, 2007, at 7:42 AM, Zahir Koradia wrote: > Hi Mike, > Is there any particular reason to have this value set to 50K?

Is there any particular reason to have this value set to 50K? Are there any dependencies on this figure anywhere? If I filled a payload at the routing layer (bypassing dtn api) of size larger than 50K(I am looking at around 2MB) and then sent it out would there be any issues?
