In an RRSF network, the local node is the node whose viewpoint you are speaking from. Its remote nodes are the other nodes in the network the local node communicates with. For example, in the network shown in Figure 1:

• From the Toronto node's point of view, the Toronto node is the local node and the Sydney and London nodes are remote nodes. The Toronto node cannot communicate with the New York node.
• From the London node's point of view the London node is the local node and the Toronto, Sydney, and New York nodes are remote nodes.
• From the Sydney node's point of view, the Sydney node is the local node and the Toronto and London nodes are remote nodes. The Sydney node cannot communicate with the New York node.
• From the New York node's point of view, the New York node is the local node and the London node is a remote node. The New York node cannot communicate with the Sydney and Toronto nodes.
