Abilene-IV Trace Data

Stratified random sampling header data from all three backbone links at IPLS between June 18th, 2004 and August 19th, 2004. All data is in the form of files named I2x-nnnnnnnnnn-d.tsh.gz, where x denotes the link the data has been captured at, nnnnnnnnnn is the UNIX start time of the capture run and d is the direction (inbound vs. outbound) for each link. When using FreeBSD, you can use the shell command

	date -r nnnnnnnnnn

I2A-nnn-0.tsh.gz	OC48c PoS	IPLS from ATLA (Atlanta)	inbound
I2A-nnn-1.tsh.gz	OC48c PoS	IPLS to ATLA (Atlanta)	outbound
I2C-nnn-0.tsh.gz	OC192c PoS	IPLS from CHIN (Chicago)	inbound
I2C-nnn-1.tsh.gz	OC192c PoS	IPLS to CHIN (Chicago)	outbound
I2K-nnn-0.tsh.gz	OC192c PoS	IPLS from KSCY (Kansas City)	inbound
I2K-nnn-1.tsh.gz	OC192c PoS	IPLS to KSCY (Kansas City)	outbound

The OC192MON hardware used in this data collection deployed precision timestamping and global CDMA/GPS time synchronization. For further details on the instrumentation please refer to this installation page.

Data is available at the following locations:

• ftp://pma.nlanr.net/traces/long/ipls/4/
