Abstract: In one embodiment, dynamic user private networks are virtually segmented within a shared virtual network. A network control system maintains the dynamic logical segmentation of the shared virtual network. User entities (e.g., user devices and/or services) are communicatively coupled to respective personal virtual networks via endpoints of access devices. Each of these endpoints is associated with a corresponding user private network. Responsive in real-time to automated processing of a received electronic particular user request, the network control system automatically modifies the dynamic logical segmentation of the shared virtual network to move a particular user entity on the shared virtual network to newly being on the first dynamic user private network without being disconnected from the shared virtual network. One embodiment uses different user private network identifiers (UPN-IDs) associated with endpoints and received packets to identify their respective user private network.

Abstract: Techniques for automated configuration are provided. A first device detects a new device connected by one or more new links in a network, and the first device transmits, to a dynamic host configuration protocol (DHCP) server, a request for a first new subnet. The first device then assigns a first address of the first new subnet to a first new interface of the first device. The first device additionally transmits a second address of the first new subnet to the new device, where the new device uses the second address to establish connectivity to the network.
