Abstract: In an example, there is disclosed a data exchange layer (DXL) broker, including: a hardware platform including a processor and a memory; a DXL service store; a traditional internet protocol (IP) network stack; a DXL driver to operate a DXL layer on top of the traditional IP network stack; and instructions encoded within the memory to: enumerate a plurality of DXL endpoints connected to the DXL broker via the traditional IP network stack; store IP network routing information and DXL identification information for the DXL endpoints in the DXL service store; receive a DXL message for a DXL endpoint, the DXL message including DXL identification information for one of the plurality of DXL endpoints; and route the DXL message to the one of the plurality of DXL endpoints via the IP network routing information for the one of the plurality of DXL endpoints.

Abstract: In an example, there is disclosed an efficient request/response routing over a publish/subscribe messaging framework. Upon receiving a request for a service, a DXL broker may identify zero or more DXL domain masters providing the service. If no DXL domain masters are available to provide the service, the DXL broker may send a response message, or publish a DXL message, indicating that the service is not available. If more than one DXL domain master provides the service, then the DXL broker may identify the best DXL domain master to service the request, and forward the request to that DXL domain master.
