Abstract: Embodiments described herein use APIs on network devices in a SDN enabled network to monitor the network traffic flowing through the network devices and determine an identity of the client initiating the network traffic. Specifically, the APIs provide a user application with user credentials, IP addresses, MAC addresses, and other identifying information mined from the network flows. Once the identity is found, the application may identify the client's current geographic location. The network devices may continue to monitor the network devices to identify any movement events associated with the client. In response to a movement event, the application may reallocate resources proximate to the new geographic location of the client.

Abstract: Techniques are provided for automating a common framework for network devices. In one example, a network device (e.g., switch, router, etc.) is configured to resolve the handling unknown packets automatically. The network device can detect whether or not a protocol is unknown to the network device, perform a lookup, determine if a matching protocol is available for the network device, and dynamically load an appropriate protocol handler into a memory of the network device. Advantageously, the present technology provides a mechanism for flexible on-demand push of protocol information. If a new protocol is noted on the network, the network device can look up the type of packet and can use a single platform kit to dynamically load drivers and control logic for that protocol onto the network device. Likewise, other network devices in the packet's path or in the network generally can load the drivers and control logic, as needed.
