Read other peoples crap kit. Actually there have been quite a few grumbles about it in professional computer magazines as well as my own experience in an area where several Wi-Fi networks tried to co-reside.

The internet? I know you have to be bloody careful when writing software, which is no longer my area unfortunately, but it has been done.

Software has nothing to do with it. Sounds like your confusing deadlocking with this (deadlocking = threads trying to access the same resources at the same time)

What BX is talking about is routing tables.

If you have a spanning tree loop you will end up with each router constantly flooding the network with packets saying "im the right router" and end up with a constantly updating route table. No packets will ever get delivered and youll have a crap load of arp packets flying around.

If you want to learn some decent network topology gubbins I would be quite happy to pm you a link to a lecturers notes however they wont make much sense without the talk that accompanies them.

simplest example of spanning tree loop is getting two or three switches and wire them up so they form a loop.... A to B, B to C, C to A.

et. voila, instant chaos until one of the switches realises that its got a loop on two ports and switches one or both of them off... if it realises that is....

9/10 the port just flaps - and rather annoyingly it flaps with a vlan interface
