摘要： In one embodiment, a device obtains transaction data regarding a transaction attempted by a client of an online application within the online application. The transaction data is captured by instrumentation code inserted into the online application at runtime. The device identifies, based on the transaction data, traffic in a network associated with the transaction. The device associates, based on the transaction data, a measure of importance with the traffic. The device causes the traffic to be sent by a networking device in the network according to its associated measure of importance.

摘要： Aspects of the disclosure include a method and associated network device. The method includes authenticating an identity of a user of a client device after the client device is associated with an access network provider. Authenticating the identity of the user comprises receiving, from an identity provider, a credential associated with the identity, and receiving, from the identity provider, information identifying a network-based service to be applied to network traffic with the client device. The method further includes establishing, using the credential and the received information, a secure connection between the access network provider and a service provider that is capable of providing the network-based service. The method further includes receiving network traffic from the service provider. Packets of the network traffic include an assurance value that enables the client device to determine that the network-based service is being provided by the service provider.

摘要： In one embodiment, a method, system, and apparatus is for storing an assigned operations, administration and management (OAM) bitstring in a memory in a BIER (Bit Index Explicit Replication) enabled router, the OAM bitstring being assigned to a BIER domain, the semantic of the OAM bitstring being to replicate and forward the OAM bitstring to neighboring bit-forwarding routers (BFRs), generating an OAM probe packet including the OAM bitstring, setting a BFR ID associated with a first BFR as a BIER header bitstring in the OAM probe packet, setting a TTL (time to live) field in the OAM probe packet to be 2, sending the OAM probe packet to a next hop BFR, and performing one of receiving the OAM probe packet back from the first BFR, and taking an alternative action if the OAM probe packet is not received back from the first BFR.

摘要： The present disclosure describes a system and method for secure energy harvesting. An access point includes a memory and a processor communicatively coupled to the memory. The processor receives, from a wireless device, a token and an identifier for a first access point that generated the token and requests the first access point to validate the token. The processor also, in response to the first access point validating the token, wirelessly communicates a first charging frame to the wireless device.

摘要： Embodiments herein describe disconnecting, by an access node, a first device having a first media access control (MAC) address due to a network violation and receiving, by the access node, information about a second device having a second MAC address different from the first MAC address. In one embodiment, the information is generated by a certificate server based on a token generated by the second device. Further, when the access node determines, based on the information, that the second device is the first device, the access node denies a connection request from the second device.

摘要： Disclosed are a system and a method for selecting an additional radio link from a second access point after a connection with a first access point has been established. The first and second access points cooperate with each other by sharing information about performance and available resources. They communicate this information to a multi-link non-AP MLD device requesting the additional radio link so that the non-AP MLD can make a selection that matches the needs of its request. Information about performance includes throughput, a delay between access points, and a delay between access points and a gateway connected to the access points.

摘要： In one embodiment, a device obtains data regarding a transaction attempted by a user within an online application that is captured by instrumentation code that is inserted into the online application at runtime, wherein the user has sufficient privileges within the online application to perform the transaction; The device sends, based on the data regarding the transaction, one or more approval requests to one or more authorizers. The device receives one or more responses to the one or more approval requests. The device blocks, and based on the one or more responses, the transaction attempted by the user within the online application via the instrumentation code.

摘要： Federation policy exchange is provided in response to receiving a sharing query from an Access Point (AP) indicating that an associated wireless network supports federated identities with data sharing, determining whether the sharing query is within sharing preferences; and in response to determining that the sharing query is within the sharing preferences, transmitting, to the AP, a positive response for identity sharing that authorizes collection and sharing of identity data with at least one entity identified in a sharing policy for the associated wireless network. In various embodiments, federation policy exchange includes transmitting a support notification, via an AP, indicating support for federated identities with data sharing within a wireless network associated with the AP; and in response to receiving a first identify sharing preference from a User Equipment (UE) that indicates that negotiation is preferred, transmitting a sharing policy for the wireless network to the UE.

摘要： In one embodiment, in-band operations data (e.g., In-situ Operations, Administration, Maintenance and/or other operations data) is added to Seamless Bidirectional Forwarding (S-BFD) packets. In one embodiment, a S-BFD packet received by a node includes a BFD discriminator and operations data. Reactive processing is identified based on the BFD discriminator. The S-BFD packet and the operations data (e.g., in an operations data field in a header of the received S-BFD packet, in an IOAM Type-Length-Value (TLV), etc.) is processed according to the identified reactive function. Examples of these reactive actions include, but are not limited to, determining a result based on processing of said particular operations data by the local node or a remote analytics server, and sending a response packet including unprocessed and/or a result of the processed operations data (e.g., performance, loss, jitter, an indication of compliance with a service level agreement, and/or another data measurement or result).
