Abstract
A distributed digital data communication network having widely dispursed nodes provides for effective transmission of messages between each node through the use of flood routing. A response message based upon stored data link status obtained when a message is received through the flood routing protocol selects the shortest time delay path for responding to that message. This process eliminates network instability.
Claims12
A distributed digital data communication network, comprising:
- a plurality of nodes geographically separated;
- a plurality of full duplex data lines connected to the plurality of nodes such that each node is connected to its neighboring nodes by a data link between each of the neighboring nodes;
- flood search means for propagating a first message through the digital data communication network from an originating node that is a member of the plurality nodes to an address homed at a destination node that is also a member of the plurality of nodes;
- and
- shortest time delay path means for propagating a response message over the shortest time delay path, in response to the first message, from the destination node to the originating node via a data link that each node of the plurality of nodes first received the first message on.
A method for conducting communications between geographically separated points in a distributed digital data communication network having a plurality of nodes geographically separated and a plurality of full duplex data links connected to the plurality of nodes such that each node is connected to its neighboring node by a data link between each of the neighboring nodes, comprising:
- propagating a first message through the digital data communication network from an originating node that is a member of the plurality nodes to an address homed at a destination node that is also a member of the plurality of nodes;
- and
- propagating a response message over the shortest time delay path, in response to the first message, from the destination node to the originating node via a data link that each node of the plurality of nodes first received the first message on.
