Adapting transmission schedules in a Radio Frequency (RF) environment may be provided. A Central Network Controller (CNC) of a Time Sensitive Network (TSN) may determine that a data path to a client device comprises a wireless link. The CNC of the TSN may generate a proposed transmission schedule for the time sensitive traffic to the client device through the wireless link in response to determining that the data path to the client device comprises the wireless link. The CNC may provide the proposed transmission schedule to a Wireless Network Controller (WLC) of the wireless link. The CNC may receive a confirmation from the WLC that the proposed transmission schedule can be met. The proposed transmission schedule may be configured in response to receiving the confirmation.

Dynamic security policy and key management for converged networks

According to one or more embodiments of the disclosure, a networking device receives a policy for an endpoint in a network. The policy specifies one or more component tags and one or more activity tags that were assigned to the endpoint based on deep packet inspection of traffic associated with the endpoint. The networking device identifies a set of tags for a particular traffic flow in the network associated with the endpoint. The set of tags comprises one or more component tags or activity tags associated with the particular traffic flow. The networking device makes a determination that the particular traffic flow violates the policy based on the set of tags comprising a tag that is not in the policy. The networking device initiates, based on the determination that the particular traffic flow violates the policy, a corrective measure with respect to the particular traffic flow.

Telemetry collection and policy enforcement using asset tagging

According to one or more embodiments of the disclosure, a device in a network identifies a packet sent via the network towards an endpoint as being a control packet for the endpoint. The device extracts one or more control parameter values from the control packet. The device compares the one or more control parameter values to a policy associated with the endpoint. The device initiates a corrective measure, based on a determination that the one or more control parameter values violate the policy associated with the endpoint.

Cloud services are provided by a distributed network including a number of geographically distributed datacenters, to client devices in accordance with data sovereignty requirements. A server within the distributed network may receive a service request and determine whether it complies with the data sovereignty requirements of the client. When the geographic location of the server does not comply with the client's data sovereignty requirements, the server may determine and transmit back to the client device a set of alternative datacenters within the distributed network that comply with the client's data sovereignty requirements. The client device may use network probes to select an alternative datacenter, and the cloud service request of the client device may be migrated from the server to the selected datacenter.

According to one or more embodiments, a first router receives a latency measurement indicative of latency associated with traffic sent from the first router to a second router. The first router calculates an asymmetrical latency as a difference between the latency measurement and a latency associated with traffic sent from the second router to the first router. The first router determines, based on the asymmetrical latency, a symmetrical latency target. The first router sends, to the second router, an indication of the symmetrical latency target. The first router and the second router adjust their respective de-jitter buffers to achieve the symmetrical latency target between the first router and the second router.

A server, in communication with a plurality of microservices in a microservices mesh environment, obtains data about inbound communications to a first microservice and outbound communications from the first microservice of the plurality of microservices. The server analyzes the data to learn an operational behavior of the first microservice and determine a firewall rule set to be applied associated with the first microservice based on the operational behavior learned for the first microservice. The server causes a micro-firewall to be instantiated for the first microservice. The micro-firewall is configured to apply the firewall rule set to inbound communications to the first microservice and outbound communications from the first microservice.

A network controller automatically adjusts a computer network based on the operational information of an industrial device. The network controller receives a notification from a network element in the computer network that the industrial device attached to the network element has an administrative shell. The administrative shell includes operational information describing the operation of the industrial device. The network controller retrieves the administrative shell from the industrial device. The network controller parses the operational information in the administrative shell to determine an intent for the industrial device, and adjusts the computer network based on the intent of the industrial device.
