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: This disclosure describes various methods, systems, and devices related to identifying an issue in a network using a probe packet. An example method includes identifying an expired data packet transmitted in a network and addressed to a destination; generating a probe packet addressed to the destination; and forwarding the probe packet. When the probe packet is received, a report indicating a routing loop in the network can be transmitted to an administrator.
