Network Statistics

I've probibly violated the AUP, but who cares!

I captured some packets from the school's network, with some suprising results. Here they are; as I first noted them.


20813 packets captured in total
5782 ARP packets captured
7788 DCE/RPC packets captured (all malformed)
2467 NBNS packets captured
802 ZIP packets captured
381 BROWSER packets captured
59 IGMP packets captured

5 computers used in local room alone
421 seconds of capture

6943818 bytes captured total, out of a 65535 byte packet size limit. So there is an average of 334 bytes/packet.

All these protocals are used to automate network structure and IP addresses. Only 3534 of these 20813 packets are used for actual 'work' packets. If the network were properly configured, 41 packets/second, or 13679 bytes/second could be saved.
