Abstract: A computing device connected to a power source via a combined power/data connection obtains an authentication request from the power source. The authentication request includes a freshness mechanism provided by the power source. The computing device signs an authentication response with a private key associated with a verified identity stored on the computing device. The authentication response includes the freshness mechanism. The computing device provides the authentication response to the power source, and receives power from the power source.

Abstract: An example method for facilitating conflict avoidant traffic routing in a network environment is provided and includes detecting, at a network element, an intent conflict at a peer network element in a network, and changing a forwarding decision at the network element to steer traffic around the conflicted peer network element. The intent conflict refers to an incompatibility between an asserted intent associated with the traffic and an implemented intent associated with the traffic. In specific embodiments, the detecting includes mounting rules from the peer network element into the network element, and analyzing the mounted rules to determine intent conflict. In some embodiments, a central controller in the network deploys one or more intentlets on a plurality of network elements in the network according to corresponding intent deployment parameters.

Abstract: An aspect of the present disclosure aims to reduce or eliminate the problems associated with processing quickly changing large sets of data. To that end, systems and methods are disclosed, enabling a semantic reasoner to identify and process incremental changes to a rules base rather than re-processing the entire rules base. Such incremental stream reasoning (i.e., only reasoning upon pushed object changes) provides an efficient and fast manner for reacting to quickly changing data.

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.

Abstract: Devices and methods that incorporate sustainability data within a header of a data packet to allow for the generation of sustainable configurations for various network devices are disclosed. Power efficiency is obtained at a node-level by including metadata to existing network flows, in an in-band/in-situ configuration. This information may be used for optimum flow placement. Received data packets may be formatted with sustainability data within a metadata shim. The received data packets are processed, and a sustainable configuration is generated for the one or more network devices. The generated sustainable configuration is transmitted to the one or more network devices to enable efficient and effective management of network devices by incorporating sustainability data into the data packets.

Abstract: Methods are provided for selectively depowering any device(s) that seem unnecessarily redundant to strike a balance between resiliency and sustainability to reduce energy costs. The analysis may include a current application mix in use on network paths. For example, a policy may require that at least two available paths are actively energized when real-time collaboration apps are running. Examples of a real-time collaboration app may be data mining in an online database stored elsewhere in the network or holding a video conference call. This double path redundancy can deliver increased application availability. And, in instances where just web/email are actively running, then a backup path that may be energized in less than a second, if a primary path loses connectivity. This lower-power method can also provide increased application availability.

Abstract: In one aspect, a method of IP obfuscation of a user device includes receiving, over an Extendible Authentication Protocol (EAP) session between a user device and a network access point, location preferences of the user device, generating, based on the location preferences or a network policy, a geohash for the user device, identifying, for the user device, an IP anchor, sending, over the EAP session, the geohash to the user device, and receiving, from the user device, network traffic, wherein the network access point utilizes the geohash and the IP anchor to route the network traffic for the user device and obfuscate IP address of the user device from third-party access.

Abstract: Energy-aware configurations can be utilized to operate a network based on sustainability-related metrics. In many embodiments, a suitable device includes a processor, a memory commutatively coupled to the processor, a plurality of elements, a communication port, and an energy-aware topology logic configured to collect topology data from one or more network devices, wherein each of the one or more network devices include a plurality of elements. The energy-aware topology logic can receive power source data and power usage data related to plurality of elements and generate an element energy coefficient (EEC) for a plurality of elements. Subsequently, the energy-aware topology logic can also generate an energy-aware configuration for at least one of the one or more network devices, and then pass the generated energy-aware configuration to the at least one network device, wherein the energy-aware configuration is configured to steer traffic based on at least one sustainability-related metric.

Abstract: A method, computer system, and computer program product are provided for performing admission control tasks. A universal reference for an executing application is obtained, wherein the universal reference identifies one or more components of the executing application by additional universal references assigned to the one or more components. A description of the executing application is determined by enumerating each additional universal reference of the one or more components and additional sub-components, wherein the description exhaustively identifies components and sub-components of the executing application. The identified one or more components and sub-components are assessed to perform an admission control operation between the executing application and a second application.

Abstract: Techniques are provided by which devices in a network may subscribe to a rapidly changing rules in central threat repository. The policies associated with threats are filtered so that just current attack vectors from within subnets learned via routing and/or forwarding information (at the network level of the network) are installed in the local access control list/policy database of the network devices. As routing changes occur, the list of applied policies are continually refined/revisited and pulled from a central security application. Publish/subscribe mechanisms ensure “zombie” policies are not left over in the device after reboot or routing changes occur.
