Hi all, I was trying to understand whether there is a standard set of API we are working on for communicating between different nodes in a cluster inside kernel. I looked at ocfs2 and the ocfs2 dlm code base seems to use tcp via o2net_send_tcp_msg and the redhat dlm seems to sctp. There is also tipc (net/tipc) code in the kernel now ( I am not sure about the details of tipc). This confuses me a lot. If i want to use all these cluster components what is the standard way. I am right now looking at clusterproc (http://www.openssi.org/cgi-bin/view?page=proc-hooks.html ) and wondering what should be the communication mechanism. clusterproc was earlier based on CI which provided a simple easy way to define different cluster services( more or less like rpcgen style http://ci-linux.sourceforge.net/ics.shtml ). Does we are looking for a framework like that ? NOTE: I am not trying to find out which one is the best. I am trying to find out if there is a standard way of doing this -aneesh -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
