Abstract: In an example, there is disclosed a computing apparatus, having: one or more logic elements, including at least a processor and a memory, providing a network simulation engine to: periodically perform a network traffic simulation; cache at least one network traffic simulation in a traffic state cache; receive a quest for additional network demand; and compute a network delta based at least in part on a difference between the request for additional network demand and the traffic state cache.

Abstract: Aspects of the embodiments are directed to systems, methods, and computer program products to program, via a northbound interface, a mapping between an endpoint identifier (EID) and a routing locator (RLOC) directly into a mapping database at a mapping system; receive, from a first tunneling router associated with a first virtual network, a mapping request to a second virtual network, the first router compliant with a Locator/ID Separation Protocol, the mapping request comprising an EID tuple that includes a source identifier and a destination identifier; identify an RLOC based, at least in part, on the destination identifier of the EID tuple from the mapping database; and transmit the RLOC to the first tunneling router implementing an high level policy that has been dynamically resolved into a state of the mapping database.
