In recent years various non-commercial tools have been developed to
analyze BGP data. When combined with BGP data collected by individual
ISPs as well as by public archives such as RouteViews and RIPE
RIS, these tools can potentially provide invaluable insight into the
operations of inter-domain routing. The goal of this second BGP Analysis
Tools BOF is to realize the potential of these tools by fostering a
closer interaction between non-commercial tool developers and the
potential users represented by NANOG.
The tool discussions will focus on the
following topics:
- BGP::Inspect: The BGP::Inspect service allows users to quickly
extract information from RouteViews-archived data. BGP::Inspect
pre-processes RouteViews data into an easily queryable format, and stores
it in a custom database. This database can then be queried via a web
interface to extract relevant AS or prefix information. In addition to
the raw update messages, BGP::Inspect provides useful and relevant summary
statistics that make it easier to extract information about routing
events.
- Routing Configuration Checker: rcc is developed to allow network
operators to verify that their networks' router configurations
satisfy high-level properties.
- Link-Rank Visualization: An open source visualization tool that
weighs AS-AS links by routes carried, Link-Rank captures link-level
events by summarizing thousands of BGP updates in compact graphs.
Besides this, scripts and instructions will be provided on setting up
Link-Rank at an ISP site.
- BGP-Repository: A project in its early design stage, which aims at
improving the organization of BGP data to offer efficient data
retrieval and real time information dissemination from routing
updates.
The basic concept of Link-Rank and BGP::Inspect was introduced at the
first BOF during
NANOG34. However, the audience did not get any hands-on
experience due to network problems, which we plan to
remedy this time.
The schedule for the BOF is:
- Introduction to BOF and objectives—Lixia Zhang
- rcc: Routing Configuration Checker—Nick Feamster
- BGP::Inspect basics—Manish Karir
- Link-Rank BGP visualization—Mohit Lad
- BGP-Repository: Objectives of BGP data organization—Dan Massey
- Demo session
Speakers will provide a quick tutorial of their tool with basic usage
instructions. The demo session that follows will be set up in
four demo areas in the room for each of the four topics of focus.
BOF participants can then go to the tool areas of interest and
get further details on installation and usage of the tools. Although
each tool demo area will provide the setup for hands-on trial,
participants in the BOF are highly encouraged to bring their own
laptops to be able to download and install the tools during the demo
session.
Objectives of the demos include:
- The BGP::Inspect demo will serve to familiarize users with the
BGP::Inspect query interface, and walk them through some simple queries
and scenarios. It will illustrate how users can perform some fairly
powerful preliminary analysis of routing events via relatively simple
queries.
- The rcc area will demonstrate rcc operating on public
configuration data (e.g., Abilene). Support will be provided for
installing and running rcc as well as for existing users. The
developers will be actively soliciting
suggestions for additional features and checks to add to the tool.
- The Link-Rank demo will focus on how to download and install the
visualization client, basic and advanced usage of the client, and
visualizing data from public archives such as RouteViews and RIPE. In
addition, instructions will be provided on installing scripts to
visualize BGP data from your own ISP. The Link-Rank corner will
provide a limited number of terminals to try out the client.
- The BGP-Repository corner will present some preliminary ideas on
BGP data organization for public sites such as RouteViews and RIPE.
Attendees can access the revised data format and provide feedback on
BGP data needs. The aim of this corner is to brainstorm on some
initial ideas for BGP data organization and collect feedback on BGP
data requirements.
BGP::Inspect is available from http://bgpinspect.merit.edu and
Link-Rank is available from http://linkrank.cs.ucla.edu; rcc
