Patent ID: 7702741

Claim:
A method of adding a new node as a master node in an information sharing topology, wherein the topology has a plurality of master nodes, said method comprising: exchanging, between the plurality of master nodes, changes to objects in the information sharing topology, wherein each master node propagates changes to objects at the master node to each other master node; establishing the new node as a slave node to a first master node of the master nodes, wherein the establishing includes configuring the first master node to propagate, to the new node, the changes to the objects in the information sharing topology; and after establishing the new node as a slave node, promoting the new node to a master node, wherein the promoting includes: configuring each given master node of the plurality of master nodes to propagate, to the new node, changes to objects in the information sharing topology at the given master node; and configuring the new node to propagate, to each of the plurality of master nodes, changes to objects in the information sharing topology at the new node.
