Can class c ip affinity in nlb encompass all real world situation? "ms news group" <noret[ at ]noret.com> 10.07.2007 11:20:04 I know nlb support class c IP affinity, but is this enough? I mean, there is no single host whose ip range may exceed class c range in real situation, true or false? If not, is there any MS solution that can achieve content affinity, such as cookie? and of course, the ssl issue also? Thanks in advance

Enough for what exactly? NLB is not perfect, but it can work well. It was made to handle SSL on web pages. Cheers, Rodney R.

If you have Internet facing NLB clusters, there will certainly be multiple class C address spaces coming to it from around the world. > If not, is there any MS solution that can achieve content affinity, such > as > cookie? and of course, the ssl issue also? You can use affinity in NLB and it will provide the support you need including SSL issues so long as there are no changes to the number of nodes. In the event of a failure, or addition, to the NLB cluster, there will be a recalculation of the algorithm which will result in the redistribution of clients. -- Russ Kaufmann MVP - Windows Server - Clustering ClusterHelp.com, a Microsoft Certified Gold Partner Web http://www.clusterhelp.com Blog http://msmvps.com/clusterhelp The next ClusterHelp classes are: July 10-13 in Denver July 16-19 in New York Sep 3 - 6 in Copenhagen
