Abstract

Defining links between networks as private links permits connection of two networks without allowing communication between their lower nodes. Nodes of a network or different networks are structured to connect and do automatic topology management. At any time that two nodes connect, all other nodes connected to the first node become connected to all the connected nodes of the second node. Thus, any job in any node can communicate with any job in any other node. There are cases where it is desirable for a node of one network to be connected to a node in another network without all of the subnodes of each becoming aware of the subnodes of the other. Jobs in the first node could then communicate with jobs in the second node, but no further down the node chain, and conversely.

Private Links Between Network Nodes

Defining links between networks as private links permits connection of two networks without allowing communication between their lower nodes. Nodes of a network or different networks are structured to connect and do automatic topology management. At any time that two nodes connect, all other nodes connected to the first node become connected to all the connected nodes of the second node. Thus, any job in any node can communicate with any job in any other node. There are cases where it is desirable for a node of one network to be connected to a node in another network without all of the subnodes of each becoming aware of the subnodes of the other. Jobs in the first node could then communicate with jobs in the second node, but no further down the node chain, and conversely. A private link between the two nodes to accomplish this desire will differ from a regular link in that no network topology information is broadcast across the link at node-connect time. The private link can be further defined such that if either side of the link wishes the link to be private, both will consider it private.
