"Implementation" is a little too long.

I do not think that was clear from the terminology section. For example the "load sharing cluster" and "cluster" does not really say that. If we add terms that describe different cluster types better, then we can more clearly describe what we are really talking about. One of the problems we have when talking about the ipsec-ha is that people use different terms and they interpret them meaning different things. Thats why I think it would be needed for this document to define good and extensive terminology for this area and use those terms consitently inside the document. > Since this is common to all the clusters that we are considering, we > don't need to define this specially.

We do need much more extensive terminology to explain also things we are not talking about, just to clarify that we do not mean them. -- kivi...@iki.fi _______________________________________________ IPsec mailing list IPsec@ietf.org https://www.ietf.org/mailman/listinfo/ipsec
