Abstract: A process includes receiving, by a first proxy for a first microservice consumer of a plurality of microservice consumers, a first request from the first microservice consumer associated with a usage of a resource. The resource is shared by the plurality of microservice consumers. The process includes allowing, by the first proxy, the first request responsive to a cumulative usage of the resource by the first microservice consumer complying with a predefined consumption quota for the first microservice consumer; and responsive to allowance of the first request, receiving, by a second proxy for the resource, a second request associated with the usage. The process includes responsive to the second request, controlling, by the second proxy, whether the usage is permitted responsive to a predefined capacity quota for the resource.

Abstract: A network management system for orchestrating a network is provided. During operation, the system generates a graph representing the network. A respective vertex corresponds to an entity in the network, and a respective edge indicates a relationship between a vertex pair. The system can determine a first and a second timestamps for a respective edge. The first timestamp indicates a time instance when a relationship indicated by the edge is established. The second timestamp indicates a time instance when the relationship is terminated. The time range between the first and second timestamps indicates an active period for the edge. The system then receives, from an interface of the system, an instruction for comparing the topology, states, and configuration of the network. The system determines the topology, states, and configurations of the network at a target time instance indicated by the instruction by traversing the active edges of the graph.

Abstract: Example implementations relate to the processing of refresh token requests at an API gateway. The API gateway determines a first time associated with receipt of the refresh token request and a second time associated with the generation of a current access token. The current access token and a refresh token in the refresh token request are provided by the API gateway to the client device for accessing a backend service. The API gateway determines whether a difference between the first time and the second time is within a pre-defined threshold duration. When the difference between the first time and the second time is within the pre-defined threshold, the API gateway denies the refresh token request for generating the new access token and transmits the current access token back to the client device.

Abstract: A system facilitating scaling of topics is provided. During operation, the system can suspend a stateful application of a topic and a stateful backup topic on an event-driven platform. The topic corresponds to a stream of events associated with the application. The system can modify configuration at the platform to allow a new set of partitions of the topic and a new set of backup partitions of the backup topic. The system can identify a state of event records from the application in a previous backup partition and identify a new backup partition allocated to the application. If they are different, the system can transfer the state to the new backup partition. The system can resume the application for generating an updated state, which is maintained at the new backup partition, based on the state and subsequent event records associated with the application.

Abstract: Example implementations relate to an access point for a wireless local area network (WLAN). In an example, an access point comprises a wireless communication apparatus to communicate with a wireless device to provide access to the network, and a management module to determine a loss of connectivity to the network by the access point, switch the first access point into a maintenance mode in response to determining the loss of connectivity to the network by the access point, and cause the wireless communication apparatus to broadcast a message in the WLAN indicating that the first access point is in the maintenance mode to cause a network device in a radio frequency (RF) neighborhood of the first access point to receive the message and report to a network management node of the WLAN that the first access point is in the maintenance mode.
