A new bgpdump tool

[Yasuhiro Ohara]

Hi,

I'm developing a new tool that can read routeviews
RIB files (MRT v2 RIB format). I call it "bgpdump2". It is similar, but
with a few additional features, to the libbgpdump.
It is going to be open source (the process is on-going).

This e-mail is to consult if there is some interest in such a tool.
I'm considering to provide a presentation in Dallas.

The motivations of creating a brand new tool are below.
1. libbgpdump seemed to have some rooms to speed up, since
   it seems to issue many small-sized read operations, rather than
   making a small number of large-sized read operations.
2. I wanted to add a few additional features (explained below)
   to such tools.
3. it didn't seem easy to modify the libbgpdump for me.

The additional features include longest prefix matching using a
PATRICIA table inside the command, diff'ing the prefixes
between peers (Note, the BGP prefixes are stored per peer
in the RIB file), and to display of some statistics of RIBs per peer.

I am from a R&D division of a tier-1 ISP (i.e., NTT Communications),
and was trying to compare BGP full route routing table instances,
possibly between ISPs.  I expect that such a tool can contribute to
get a detailed view on how/why BGP full route routing tables are
different.  For example, we're going to need the longest matching
lookup function to see if the differentiating prefix is covered by a
shorter prefix.

However I'm not greatly succeeding so far, since the reason for
a prefix that is differentiating depends on case by case
(and there are various reasons including "the business relationship"),
and I could not get a summarized view after the comparison of
(say) two BGP full route routing tables.

I would like to get some feedback from the community on these things.
I can provide in Dallas some more details of my tool,
some performance benchmark of it,
and some statistics of RouteView's RIB files.

Would you kindly share your opinions on this ?

Thanks.

Best regards,
Yasu
