Protocol:
--------
The Access Node Control Protocol (ANCP) is a standards based protocol intended
to facilitate the transmission of control and dynamic subscriber configuration
information between an access node (DSLAM) and a L3 subscriber aware controller
(BRAS/NAS).
It is a TCP/IP based protocol using GSMPv3(RFC 3292) messages.
Uses TCP port 6068.
Dissector:
----------
The dissector can dissect the following ANCP messages now:
- Adjacency messages
- Event Messages (Port Up/Down)
- Port Management messages
And adds statistics for the same.
Test:
-----
The dissector has been fuzz tested with upto 100 iterations at error
prob 0.02 and 0.03
