Network Outage Element Watch

Looking at some of my study notes reminded me today, that not all network outages are man made. Elemental power is sometimes at work.

Internet Network Traffic Packet Archive

Some packets, I just wont see every day. The Internet Traffic Archive has 4 million-packet traces of LAN and WAN traffic, 30 days of wide-area TCP connections, Six months of Web client traces and more.

The traces are a very helpful review of network traffic that I do not normally see on a daily basis.

It has been interesting identifying and reading packets that are slightly irregular.

The Internet network traffic by ACM SIGCOMM is at http://ita.ee.lbl.gov/html/traces.html

Enjoy!
