Q: "Spanning tree algorithm?" A: I have found a good reference for ethernet is the O'Reilly book: "Ethernet: The Definitive Guide" by Charles E. Spurgeon, 2000. There is a standard method that ethernet switches use to detect loops, and will shut down one of the links in the loop. Essentially they form a tree by sending out special packets amongst themselves. I just did a google search on "spanning tree algorithm ethernet switch" and found this from Cisco: http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/sw_ntman/cwsimain/cwsi2/cwsiug2/vlan2/stpapp.htm "Understanding Spanning-Tree Protocol" And this article from Network World Fusion: http://www.nwfusion.com/netresources/0524spanning.html "Spanning tree is still with us" On Thu, 29 Mar 2001, Grenyer, Richard wrote: > Someone wrote: > > >And your N networks had to be isolated from each other, > >so that their tree-spanning algorithm, etc. would not get confused > > What is this tree-spanning algorithm.
