Heterogenous Networks Data Traces

This page contains data traces from real networks obtained using D-ITG.

The archives are here in tar.gz format. Each archive contains files with samples of measured QoS parameters related to several end-to-end paths. The considered QoS parameters are packet loss, delay, and jitter. Samples are obtained by adopting an active measurement approach, sending probe packets by using D-ITG with a packet rate of 100 pps. File names have the following format:

        xxx-to-yyy-ttll[-ddee]-ppp.tar.gz

where

  xxx= Access network at sender side (with the term wired we mean 100 Mbps Ethernet connection; ADSL is an 640 Kbps connection; with the term wireless we mean 802.11b connection (ap = access point, ah = ad hoc mode))
  yyy= Access network at receiver side (with the term wired we mean 100 Mbps Ethernet connection; ADSL is an 640 Kbps connection; with the term wireless we mean 802.11b connection (ap = access point, ah = ad hoc mode))
  tt: Operating System at Sender Side (with the term Win we mean Win32 OS; with the term lin we mean Linux OS)
  ll: Operating System at Receiver Side (with the term Win we mean Win32 OS; with the term lin we mean Linux OS)
  dd: Device at Sender Side (with the term lap we mean laptop; with the term ws we mean workstation). It is an optional field.
  ee: Device at Receiver Side (with the term lap we mean laptop; with the term ws we mean workstation). It is an optional field.
  ppp: Used Protocol (TCP, UDP, or SCTP)

Each archive contains several files with the indication of the:
- used packet size (64, 512, 1024 bytes)
- measured QoS parameter (packet loss, delay, or jitter).

Each sample is calculated using non-overlapping windows of 10ms length.
This is not true when a file is labeled with "PERPACKET": in this case the samples are calculated per packet.
