Abstract: A system may assist with checking policy impact in a software-defined infrastructure environment. The system's data analysis may enable it to discover and quantify the impact of policies on software-defined infrastructure objects in the same or different layers.

Abstract: A system may assist with checking policy impact in a software-defined infrastructure environment. It may perform continuous learning of impact using emulations under varying conditions and may take a statistical and machine learning based analysis approach on the data obtained from emulations. The system's data analysis may enable it to discover and quantify the impact of policies on software-defined infrastructure objects in the same or different layers.

Abstract: The concepts and technologies disclosed herein are directed to parallelism for virtual network functions (“VNFs”) in service function chains (“SFCs”). According to one aspect, a packet processing system can receive instructions to process, in parallel, at least a portion of a plurality of data packets associated with an SFC including a plurality of VNFs. The system can create a copy of at least the portion of the data packets. The system can send the copy of at least the portion of the data packets to at least two VNFs. The at least two VNFs can process, in parallel, the copy of at least the portion of the data packets. The system can receive, from the at least two VNFs, processed packets including the copy of at least the portion of the data packets and processed, in parallel, by the at least two VNFs. The system can combine the processed packets.

Abstract: Network function may be dissected and the common functions abstracted into inspection network function as the first hop, for example, of a service function chain. The inspection network function then inserts a value into the network service header (NSH) which may be used for the rest of the network functions of the service function chain.

Abstract: Performance issues in a service function chain having a plurality of resources and a plurality of network functions each having a network function queue are diagnosed. Each network function queue is monitored and queueing information for input packets for each of the plurality of network functions is dumped to a data store. Each resource that is under contention is identified as well as which of the network functions is a contender for the resources. A diagnosing algorithm is used to diagnose performance problems and an impact graph for each victim packet is generated. A summary of results as a list of rules is then provided.

Abstract: Systems and methods are disclosed for parallelizing service function chains. A method comprises receiving a sequential service function chain comprising a plurality of network functions, receiving a plurality of operations, determining at least two network functions are capable of being parallelized, aggregating operations of the plurality of operations associated with the at least two network functions into a network function segment, determining whether another network function is capable of being parallelized with the network function segment, based on the determining: aggregating an operation associated with the another network function into the network function segment when the another network function is capable of being parallelized with the network function segment, or pushing the network function segment as a completed segment of a hybrid service function chain when the another network function is not capable of being parallelized with the network function segment, and implementing the hybrid service function chain.

Abstract: A processing system having at least one processor may obtain a feature set from a camera frame of a client device, perform a feature reduction of the feature set to produce a reduced feature set, generate a compressed representation from the reduced feature set, compare the compressed representation of the reduced feature set to a plurality of compressed representations of known objects stored in one or more hash tables to identify an object in the camera frame, and provide an identification of the object to the client device.
