MAWI Working Group Traffic Archive

Packet traces from WIDE backbone

This is a traffic data repository maintained by the MAWI Working Group of the WIDE Project.

Currently, traffic traces are collected at the following sampling points:

daily traces at the transit link of WIDE to the upstream ISP, in operation since 2006/07/01: 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024.
longer traces: 48-hour-long traces on 2007/01/09-11, 72-hour-long traces on 2008/03/18-20, 96-hour-long traces on 2009/03/30-04/02, 83-hour-long traces on 2010/04/13-16, 63-hour-long traces on 2012/03/30-04/01, 72-hour-long traces on 2013/06/25-27, 24-hour-long traces on 2014/10/02, 2014/12/10, 2021/04/14, 2023/04/12, 48-hour-long traces on 2015/12/02-03, 2017/04/12-13, 2018/05/09-10, 2019/04/09-10, 2020/04/08-09, 2022/04/13-14 as part of a Day in the Life of the Internet project.
The link was upgraded from 100Mbps to 1Gbps with 150Mbps Committed Access Rate (CAR) on June 1 2007, and then, the CAR was officially removed on June 21, 2016.
Data is missing from November 4 to December 15 in 2022, due to a hardware failure in the middle of the POP migration.

WIDE started operation at another IX (BBIX) on July 31, 2023 and, as a result, the transit traffic was considerablly reduced. To restore the monitoring coverage, this IX traffic was added to the samplepoint-F on August 8, 2023. Now, the samplepoint-F contains the traffic from the 2 links, the transit link and the BBIX link.

Note: there are a considerable amount of duplicated packets in the traces from May 28 to September 3, 2015, due to a mis-configured VLAN at the monitored router. (A quick way to remove the duplicates is to use editcap in the wireshark distribution, e.g., "editcap -D64 infile outfile".)

Note about a large amount of ICMP traffic is in the traces since 2013, probing the entire IPv4 space by the USC ANT project. The probing started in September 2011 with sporadic probing, but changed to constant higher-rate probing since March 27, 2013. The probing once terminated on December 4, 2020, but restarted on July 2, 2023.

Older traces:

samplepoint-G (2018 May -- 2020 June)

longer traces: 24-hour-long traces on 2018/05/09, and 2019/04/09, and an 8-hour-long trace on 2020/04/08.
samplepoint-A (terminated in Nov 2000)
daily trace of a trans-Pacific T1 line (one of them): 1999, 2000
Y2K roll-over
daily trace of another trans-Pacific line (18Mbps CAR on 100Mbps link) This link was terminated on 2006/07/01, and replaced by Samplepoint-F: 2000, 2001, 2002, 2003, 2004, 2005, 2006
107-hour-long traces from another US-Japan link taken from 1999/05/10 10pm to 1999/05/15 7am.
The link was upgraded from 4Mbps to 10Mbps on 5/13 around 15:30.
24-hour-long traces on 2003/02/27, 2005/01/07, 2005/09/22, and 2006/03/03.
plot graphs by aguri: port numbers: 2001, 2002, 2003, 2004, 2005, 2006 (wide-members only: addresses: 2001, 2002, 2003, 2004, 2005, 2006)
daily trace at an IPv6 line connected to 6Bone: 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009
daily trace at an IPv6 line connected to WIDE-6Bone: 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009
yet another US-Japan line (OC-3) which came into operation in Dec 2001:
plot graphs by aguri: port numbers: 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009 (wide-members only: addresses: 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009)

Traffic traces are made by tcpdump, and then, IP addresses in the traces are scrambled by a modified version of tcpdpriv.
The soure code of a set of tools used to create our archive is also available.

MAWILab is a database that assists researchers to evaluate their traffic anomaly detection methods. It consists of a set of labels locating traffic anomalies in the MAWI archive (samplepoints B and F). The labels are obtained using an advanced graph-based methodology that compares and combines different and independent anomaly detectors. The data set is daily updated to include new traffic from upcoming applications and anomalies.

You may use WIDE traffic data for only research purposes. Actions that trespass upon users' privacy are prohibited.

Here is guidelines for protecting user privacy in WIDE traffic archive. (japanese version).
