## Abstract

Techniques to facilitate enhanced addressing of local and network resources from a computing system are provided herein. In one implementation, a method of operating an object-based memory management unit on a computing system to unify addressing of local and network resources includes maintaining a mapping of virtual addresses to local addresses and network addresses, and identifying resource requests that use the virtual addresses. The method further provides handling the resource requests per the mapping, and wherein a given request of the resource requests implicates a network resource, accessing the network resource associated with the given request over at least the network.
