Project: Referral Super Peer

1.  Overview
------------
The files included here are from an experiment run from October
through December 2006 to measure the prevalence and extent of
Internet port blocking.  The methodology used, summary of
results, and discussion can be found in the page linked to from 
  http://ana.csail.mit.edu/rsp/  

This paper was published as part of the 2007 Passive and Active
Measurement (PAM) Conference:  
  "The Internet's Not a Big Truck: Toward Quantifying Network
   Neutrality", R. Beverly, S. Bauer and A. Berger.

The data here is to enable others to perform similar analyzes on
the data or to compare properties of our results to other
studies.


2.  Files
------------
We present the data as MySQL dump format files, which should
facilitate easy re-creation of our database for those interested.
In particular, our database has three primary tables:
  1) BGP: A mapping between a global BGP CIDR prefix and a unique
     identifier
  2) Sent: Referrals sent to a given IP, BGPId for Port at Time
  3) Received: Connections attempted from IP, BGPId for Port at
     Time

The schemas of the tables are contained within the dump files and
are also below for reference.


3. Data
------------
We include all of the data as used in the analysis presented in
our PAM paper.  We have however anonymized the data.  In
particular, we have:
  - Anonymized all BGP prefixes
  - Anonymized all IP addresses

For IP anonymization, we use the prefix-preserving Crypto-PAn
toolkit:
  http://search.cpan.org/~jtk/IP-Anonymous-0.04/

The purpose of our experiments is to understand system-wide
behavior and trends.  As such, we are not seeking to promote the
examination of particular clients with this dataset.  

CREATE TABLE BGP (
  Id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  Prefix INT UNSIGNED NOT NULL,
  Mask TINYINT UNSIGNED NOT NULL,
  NextPort SMALLINT UNSIGNED NOT NULL
);

CREATE TABLE Sent (
  Id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  IP INT UNSIGNED NOT NULL,
  PrefixId INT UNSIGNED NOT NULL,
  Port SMALLINT UNSIGNED NOT NULL,
  Time TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE Received (
  Id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  IP INT UNSIGNED NOT NULL,
  Port SMALLINT UNSIGNED NOT NULL,
  PrefixId INT UNSIGNED NOT NULL,
  Time TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);
