    Abstract: A method for establishing a VPN with a client device is provided. In the method, an AP can receive an access request directed to an OpenRoaming (OR) Service Set Identifier (SSID) from the client device. The AP can send the access request to an OR connector. In response to the access request, the AP may receive an access response from the OR connector. The access response can include an attribute indicating an address to connect to a company Virtual Private Network (VPN) headend. The AP may then use the attribute to establish the VPN connection with the company VPN headend.

    Abstract: Embodiments provide techniques for transmitting data packets across a deterministic Ethernet network. Embodiments receive, at a first device in the deterministic Ethernet network, a deterministic binary schedule specifying timing information for transmitting data fragments relating to a plurality of data flows. Data packets to transmit to a destination device within the deterministic Ethernet network are received at the first device. Embodiments include fragmenting each of the data packets into two or more fragments and encoding at least one of the two or more fragments for each of the data packets with a respective sparse graph code. The encoded fragments are transmitted to the destination device, across multiple paths through the deterministic Ethernet network, according to timing information specified in the deterministic binary schedule.

    Abstract: Techniques are disclosed for exchanging anonymized information between autonomous systems. In one example, a method comprises accessing an eigenvalue, wherein the eigenvalue is based on topology data associated with the first autonomous system; encoding the eigenvalue into a message; and transmitting, by a network element located in the first autonomous system, the message to an external edge router located in the second autonomous system. A further method can comprise receiving, by a network component located in a first autonomous system, a message, wherein the message comprises an eigenvalue and the message is received from an external network element located in a second autonomous system; accessing another other eigenvalue, the another eigenvalue corresponding to an autonomous system different from the first autonomous system; analyzing the another eigenvalue and the eigenvalue; and executing, by the network element, an action based on the analyzing.

    Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for extending and standardizing heterogeneous network devices using instrumentation. A method includes: receiving, by a client device using a first network interface, instrumentation bytecode to supplement with a data link layer from a management device, wherein a verifier of the client device verifies that the instructions of the bytecode are constrained for security based on a plurality of rules; in response to detecting a trigger at the client device, executing the instrumentation bytecode at the client device to perform at least one function associated with the trigger; and sending a response from the client device based on an execution result of the instrumentation bytecode.

    Abstract: A method is provided that is performed in a wireless network to detect a rogue wireless device. The method comprises detecting a suspect wireless device in the wireless network based on messages transmitted by the suspect wireless device using a first Media Access Control (MAC) address that is also used by a valid wireless device in the wireless network. When a suspect wireless device is detected, the method next includes sending to the valid wireless device in the wireless network a request configured to cause the valid wireless device to change its MAC address. After the valid wireless device has changed its MAC address, the method involves observing messages transmitted by the suspect wireless device in the wireless network. The method then includes determining that the suspect wireless device is a rogue device when the suspect wireless device continues to transmit messages using the first MAC address.
