DNS and ICMP schemas?

[prashantbarca]

https://github.com/DFDLSchemas/ethernetIP/tree/master/src/main/resources/com/owlcyberdefense/dfdl/xsd this path does not seem to contain schemas for ICMP and DNS files. Is there a plan to add them in the future?

There is an ICMPv4 packet described in the ethernetIP.dfdl.xsd file.

I don't know of active development on these schemas. Your contributions would be welcome.

To some degree this schema was Proof-of-Concept to illustrate DFDL schemas and teach people about DFDL because many people are familiar with the IP protocol stack and so can follow these examples intuitively.

Deep in my todo list was to update all the packet types to include checksum calculations of the various kinds. But I don't have any idea if/when that will ever become priority for me. Right now only ipV4 has a checksum. I think the Apache Daffodil team are not completely happy yet with the APIs for these sorts of checksum extensions, so those might evolve.
