Abstract: Disclosed herein is a distributed ledger method for a fifth-generation (5G) network. A network slice is created in the 5G network and a root block is generated in response, containing parameters of the network slice and contracts between participants in the network slice. A blockID of the root block is transmitted to identified participants in the network slice, who sequentially commit a plurality of new blocks to a blockchain beginning from the root block. The plurality of new blocks comprises auditing information of the network slice, wherein the information is collected by the participants in the network slice. The blockchain is stored in a blockchain network of a plurality of disparate blockchains. Desired auditing information for the network slice is retrieved by using the blockID of the root block to traverse the blockchain beginning at the root block until all blocks with the desired auditing information have been read.

Abstract: A method including receiving a source file containing a plurality of documents which, to a computer, initially are indistinguishable from each other. A first classification stage is applied to the source file using a convolutional neural network image classification to identify source documents in the multitude of documents and to produce a partially parsed file having a multitude of identified source documents. The partially parsed file includes sub-images corresponding to the plurality of identified source documents. A second classification stage, including a natural language processing artificial intelligence, is applied to sets of text in bounding boxes of the sub-images, to classify each of the multitude of identified source documents as a corresponding sub-type of document. Each of the sets of text corresponding to one of the sub-images. A parsed file having a multitude of identified sub-types of documents is produced. The parsed file is further computer processed.

Abstract: A web conferencing operator can enable participants to share multimedia content in real-time despite one or more of the participants operating from behind a middlebox via network address translation (NAT) traversal protocols and tools, such as STUN, TURN, and/or ICE. In NAT traversal, participants share a transport addresses that the participants can use to establish a joint media session. However, connectivity checks during NAT traversal can expose a media distribution device hosted by the web conferencing operator to various vulnerabilities, such as distributed denial of service (DDoS) attacks. The web conferencing operator can minimize the effects of a DDoS attack during the connectivity checks at scale and without significant performance degradation by configuring the middlebox to validate incoming requests for the connectivity checks without persistent signaling between the web conference operator and the middlebox.

Abstract: Modern day user applications leverages new communication technologies such as WebRTC, WebEx, and Jabber allow devices to connect and exchange media content including audio streams, video streams, and data stream/channels. The present disclosure describes mechanisms for a Port Control Protocol (PCP) server to provide feedback to PCP clients to enforce certain policies on the transport of such media content for a network. A policy may include a traffic handling policy for enforcing differentiated quality of service characteristics for different types of media streams. Another policy may include a security policy ensuring a data files being transmitted over a data channel from one endpoint travels to a security application via a relay element before the packets reaches another endpoint. The mechanisms are transparent to the endpoints, and advantageously preserve the user experience for these user applications.

Abstract: An example method includes establishing a communication session between a first participant and a second participant, programming, via a control plane, a stream classifier which is to process packets associated with the communication session with classification logic. The method includes receiving a first packet at the stream classifier and, when the communication session requires recording, applying the classification logic at the stream classifier to route the first packet into a chosen service function path that includes a recording service function which reports media quality data to the control plane. Based on the media quality data, the classification logic is updated to cause a migration of the communication session to a new chosen service function path.

Abstract: A communication session is established between at least a first endpoint and a second endpoint, either or both of which is behind at least one network device in a network that performs network address translation. Candidate path information is obtained that indicates candidate paths in the network through which the communication session can traverse, taking into account, network address translation occurring in the network. The candidate path information is analyzed against training data and data about conditions observed on one or more candidate paths for the communication session with a machine learning-based interface selection process to produce path recommendation information indicating whether one or more candidate paths should or should not be used for the communication session between the first endpoint and the second endpoint. The path recommendation information is supplied to an endpoint in the communication session.
