Simpleweb / University of Twente - Traffic Measurement Data Repository

From this location you can download anonymized (tcpdump/libpcap) packet traces taken from various locations in the Netherlands. Please see this PDF document for details.

A short description of the locations:

• Location 1: On location #1 the 300 Mbit/s (a trunk of 3 x 100 Mbit/s) ethernet link has been measured, which connects a residential network of a university to the core network of this university. On the residential network, about 2000 students are connected, each having a 100 Mbit/s ethernet access link. The residential network itself consists of 100 and 300 Mbit/s links to the various switches, depending on the aggregation level. The measured link has an average load of about 60%.
  Measurements have taken place in July 2002.
  
  
• Location 2: On location #2, the 1 Gbit/s ethernet link connecting a research institute to the Dutch academic and research network has been measured. There are about 200 researchers and support staff working at this institute. They all have a 100 Mbit/s access link, and the core network of the institute consists of 1 Gbit/s links. The measured link is only mildly loaded, usualy around 1%.
  The measurements are from May - August 2003.
  
  
• Location 3: Location #3 is a large college. Their 1 Gbit/s link (i.e., the link that has been measured) to the Dutch academic and research network carries traf c for over 1000 students and staff concurrently, during busy hours. The access link speed on this network is, in general, 100 Mbit/s. The average load on the 1 Gbit/s link usually is around 10-15%.
  These measurements have been done from September - December 2003.
  
  
• Location 4: On location #4, the 1 Gbit/s aggregated uplink of an ADSL access network has been monitored. A couple of hundred ADSL customers, mostly student dorms, are connected to this access network. Access link speeds vary from 256 kbit/s (down and up) to 8 Mbit/s (down) and 1 Mbit/s (up). The average load on the aggregated uplink is around 150 Mbit/s.
  These measurements are from February - July 2004.
  
  
• Location 5: Location 5 is a hosting-provider, i.e. a commercial party that offers floor- and rack-space to clients who want to connect, for example, their WWW-servers to the Internet. At this hosting-provider, these servers are connected at (in most cases) 100 Mbit/s to the core network of the provider. The bandwidth capacity level of this hosting-provider's uplink (that we have measured) is around 50 Mbit/s.
  These measurements are from December 2003 - February 2004.
  
  
• Location 6: On location #6, a 100 Mbit/s Ethernet link connecting an educational organization to the internet has been measured. This is a relatively small organization with around 35 employees and a ittle over 100 students working and studying at this site (the headquarter location of this organization). All workstations at this location (~100 in total) have a 100Mbit/s Lan connection. The core network consists of a 1 Gbit/s connection. The recordings took place between the external optical fiber modem and the first firewall. The measured link was only mildly loaded during this period.
  These measurements are from May - June 2007.
