Disclosed embodiments provide a virtual topology in response to an allocation request. The virtual topology is a synchronized subgraph of the physical topology. The synchronized subgraph virtual topology mirrors the physical topology in terms of tree structure. However, merely sharing the physical topology with users/customers is not feasible, as it may reveal additional infrastructure details such as MAC addresses, IP addresses, and the like, that can compromise security and/or jeopardize multi-tenant operations. Disclosed embodiments create virtual topology structures with obfuscated node data, so that important data such as physical IP addresses and/or MAC addresses are hidden from the end-users. Thus, disclosed embodiments provide the benefits of performance enhancement that comes from sharing the topology without the downside of compromising security by revealing physical topology details.
