#12 New Capture file format: JNS

[Sly Technologies]

Design new capture file format that can utilize all
features of jNetStream.

The required features are as follows:
1) Certain amount of binary format compatibility with
PCAP format so that PCAP capture files can be turned
into JNS capture files in place (no file copying).

2) Allow JNS capture file to store user specified
bindings and possibly entire Protocol definitions.

3) Allow per packet flexibility on Datalink protocol

4) Allow per packet flexibility so that record sizes
can be independent of packet sizes. So when packets
shrink (due to user modification) the file does not
have to be re-written.

5) Allow storage of generic properties so that
additional META data can be set on the file. I.e.
passwords, encryption, capture device information.

6) Allow multiple entity captures to the same file.
Could be multiple interfaces or even multiple remote
systems. Need to differentiate who the source of data was.

7) Include counters and statistics

8) Future expansion capabilities for other features,
expert analysis storage, etc..
