I have a four-node network in a ring. I have determined the availability of each one of the four connections, but...
I don't know how determine the availability of the whole network. Can you help?
It's difficult to answer this question without more information. My suggestion would be to make sure your "ring" has at least two data paths. You can use the example of a normal SONET network to help you. You can refer to: http://www.sonet.com/docs/faq.htm for more information. If this is a Fibre Channel network, then make sure there are at least two interswitch links (ISL) between the switches, or create a "fully meshed fabric" such as below.
