Abstract: A computer-implemented method for increasing the scalability of software-defined networks may include (1) maintaining a set of databases collectively configured to (i) store a set of flow entries that direct network traffic within a software-defined network and (ii) facilitate searching the set of flow entries based at least in part on at least one key whose size remains substantially constant irrespective of the number of flow entries within the set of flow entries, (2) detecting a request to perform an operation in connection with a flow of data packets within the software-defined network, (3) identifying at least one attribute of the flow of data packets in the request, and then (4) searching, using the attribute of the flow of data packets as a database key, at least one database within the set of databases to facilitate performing the operation. Various other methods, systems, and apparatuses are also disclosed.

Abstract: A computer-implemented method for interfacing software-defined networks with non-software-defined networks may include (1) receiving at least one packet via software-defined network at a switching device, (2) searching a set of flow entries that collectively direct network traffic within the software-defined network for a flow entry that corresponds to the packet, (3) determining that the packet is destined for a non-software-defined network based at least in part on the search, and (4) forwarding the packet to the non-software-defined network via a logical tunnel that interfaces the software-defined network with the non-software-defined network by connecting a virtual port within the software-defined network to a virtual port within the non-software-defined network. Various other methods, systems, and computer-readable media are also disclosed.
