Partial source routing for cross-network routing

A bridge node comprising:

• one or more processors;
• and
• one or more computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform acts comprising:
• receiving, from a first node associated with a first network, data and first source routing data for the data, the first source routing data comprising:
• a first address identifying the first node, the first address being of a first address format, wherein the first address format corresponds with the first node being associated with the first network;
• and
• a second address identifying the bridge node, the second address being of a second address format that is longer than the first address format, wherein the second address format corresponds with the bridge node being associated with a second network;
• determining a routing path associated with sending the data to a second node;
• determining that the second node is associated with the second network;
• generating, based at least in part on determining that the second node is associated with the second network, second source routing data comprising a third address that identifies the second node, the third address being of the first address format based at least in part on the second node being associated with the second network;
• and
• sending the data with the second source routing data.

A method comprising:

• determining, by a first node that is part of a first network, a routing path associated with sending data from the first node to a second node;
• determining, by the first node, that the second node is part of a second network;
• identifying, based at least in part on determining that the second node is part of the second network, a third node along the routing path that is part of the first network;
• identifying, based at least in part on determining that the second node is part of the second network, a fourth node along the routing path that is part of the second network;
• and
• sending, based at least in part on identifying the third node and the fourth node, the data and source routing data for the data, the source routing data comprising:
• a first address corresponding with the third node, the first address being of a first address format, wherein the first address format is associated with the first network;
• and
• a second address corresponding with the fourth node, the second address being of a second address format that is longer than the first address format, wherein the second address format is associated with the second network.
