  • receiving a message by said name server from one of said processors requesting an event which affects the membership of one of the groups;

    determining what event is being requested by said message;

    determining which group the event is for;

    storing an identification of the requesting processor in an interested party set for the group;

    determining if the group has a group leader;

    if the group does not have a group leader, storing the event to be performed responsive to the message in a lookup queue to be processed when a group leader has been established;

    establishing as the group leader, the first node to send a message to the name server requesting an event; and

    processing all events stored in the lookup queue after said group leader is established for said group.
