Hi all,
I am wondering if any one knows about a generic parser which takes a
packet (mbuf) of a certain protocol (e.g RSVP ) as input and generates
some data structre representing the packet ?
I've been searching for a while and found that ethereal and tcpdump
for example use specific data structres and functions to dissect each
protocol packets. Is this the only approach possible ?
My supervisor suggested using a TLV (Type/Length/Value) approach
instead. Any opinions about that?
If no such a parser exists is there any practical reason why ?
Thanks,
Aziz
