Important. Query on Clustered environment

Question

          1. In 6.1, does clustering work only with IP Multicasting or do IP Sockets also
          come into picture. the documentatin of clusters in 6.1 mentions that it uses only
          IP Multicasting whereas the documentation of 5.1 suggests that WLS uses both.
          2. When would IP Sockets be used typically?
          Thanks,

Answer 1

          In both 51 and 61, IP Multicast is used for sending cluster-wide heartbeats,
          cluster-wide JNDI updates and info about a Server is joining/leaving the cluster.
          Session replication information is sent via peer to peer IP socket connections
          between the primary and the secondary servers in the cluster.
          hope this helps,
