Day in the Life of the Internet, March 18-19, 2008 (DITL-2008-03-18) - 11021 files, 2008‑03‑18 to 2008‑03‑20

The Day in the Life of the Internet (DITL) measurement project aims to provide simultaneous capture of a variety of worldwide Internet measurements for further analysis by research scientists. This collection groups the DITL measurements on March 18 and 19, 2008. These measurements include (amongst others): OARC DNS traces, passive traffic traces (from Japan, South Korea and the USA), BGP data and topology data.

PoliTo Skype Traces 2006-05-29 - 4 files, 2006‑05‑29 to 2006‑06‑02

Traces contain Skype network traffic from PoliTO users. We developed a classification tool which was successfully able to classify traffic packets generated by Skype, starting from a trace captured on our campus main link.

Day in the Life of the Internet, January 9-10, 2007 (DITL-2007-01-09) - 11540 files, 2007‑01‑09 to 2007‑01‑11

The Day in the Life of the Internet (DITL) measurement project aims to provide simultaneous capture of a variety of worldwide Internet measurements for further analysis by research scientists. This collection groups the DITL measurements on January 9 and 10, 2007. These measurements include (amongst others): OARC DNS root and AS112 traces, passive traffic traces from Japan, South Korea and the USA, and skitter topology traces.

SUNET OC 192 Traces - 702 files, 2006‑04‑07 to 2006‑11‑26

This is the super-collection of two sets of anonymized packet headers from the SUNET backbone collected by the MonNet Project (Chalmers University of Technology). The datasets were collected during April and fall 2006 in measurment intervals of 10 and 20 minutes. In total, the datasets represent 71 hours of backbone traffic, collected on 106 days. The traces include 39 billion IPv4 packets, carrying 27 TB of data in about 840 million TCP und UDP flows.

CRAWDAD datasets - 23572 files, 2002‑07‑20 to 2007‑03‑01

This collection contains datasets that are indexed both in DatCat and in the Community Resource for Archiving Wireless Data At Dartmouth (CRAWDAD).

LBNL/ICSI Enterprise Tracing Project - 246 files, 2004‑10‑04 to 2005‑01‑08

Packet traces of internal enterprise traffic collected at a medium-sized site. Traces span 100+ hours of activity from several thousand internal hosts and include some packet payloads. The traces allow researchers to examine enterprise traffic and to determine the similarities and differences between enterprise and wide-area Internet traffic. The data is anonymized and publicly available. By releasing these traces we hope to provide a resource for others to use in studying patterns and dynamics within enterprises. Further, we hope that providing a corpus of "background traffic" for security researchers will allow for the sound evaluation of defense mechanisms in the context of the "crud" that appears on real networks.

OARC DNS root traces January 10-11, 2006 - 8983 files, 2006‑01‑10 to 2006‑01‑11

This data was gathered as a representative sample of two days in the life of the three DNS Anycast root servers. The dataset contains DNS traffic as seen by most instances of C-root, F-root, and K-root on January 10th and 11th, 2006, UTC. Potential uses include examining the global DNS traffic to DNS roots and Anycast. The data contains primarily inbound DNS traffic, although a few instances include outbound. We collected data for 4 of 4 C-root, 33 of 37 F-root, and 16 of 17 K-root instances.

SIGCOMM 2001 Conference Wireless Trace - 25 files, 2001‑08‑29 to 2001‑08‑31

Anonymized traces of wireless traffic and network performance from attendees at the SIGCOMM 2001 conference held at the Mandeville Auditorium at the UCSD campus from August 29-31, 2001. The trace includes 300,000 flows from 195 users consuming 4.6 GB of bandwidth.

CAIDA OC48 Traces 2003-04-24 - 26 files, 2003‑04‑24 to 2003‑04‑24

Anonymized packet header traces collected in both directions of an OC48 link on Apr 24, 2003 (1 hour). This link is a west coast peering link for a large ISP. Possible uses include research on the characteristics of traffic, including application breakdown, security events, geographic and topological distribution, and flow volume and duration. Statistics (both directions): 13GB of traces, 203 million packets, and 96GB of observed IP traffic.
