The disclosure relates to a system and method of optimizing one or more paths between an Application Programing Interface (API) gateway and one or more endpoints. Properties associated with each of a plurality of paths between at least one device and an API gateway are collected, and the properties associated with each of the plurality of paths are monitored to determine a current level of performance for each of the paths. Using gathered data, the API gateway can then analyze, using machine learning, the current level of performance for each of the paths and the current load of the at least one device to determine if a corrective action is needed to maintain an optimal performance of the API gateway, the plurality of paths, and the at least one device.

Predictive system for optimizing API behaviors

Techniques for an Application Programming Interface (API) gateway to workload placement and load balancing in a distributed system. The API gateway may route API requests, responses, and so forth, via a plurality of paths between the API gateway, API endpoint devices and API client devices. The API gateway may collect the path properties for the plurality of paths between itself, and the client devices and API endpoints. Additionally, or alternatively, the API gateway may collect process properties indicating the statistics of specific processes. Using this data, the API gateway may determine that a particular path, a particular process, etc., has experienced performance degradation. The API gateway may further determine, and perform, a remedial action to take to remedy the performance degradation of the path or processes.

Using an application programming interface (API) gateway to manage communications in a distributed system

Techniques for using application network requirements and/or telemetry information from a first networking technology to enhance operation of a second networking technology and optimize wide area network traffic are described herein. The techniques may include establishing a communication network for use by applications of a scalable application service platform, the communication network including a first networking technology and a second networking technology. In this way, a request to establish a connection for use by an application may be received by the first networking technology. The request may include an indication of a threshold service level of the connection. In response to the request, the first networking technology may determine whether the second networking technology is capable of hosting the connection. If the second networking technology is capable of hosting the connection, the connection may be established such that application traffic is sent or received using the second networking technology.

Combining networking technologies to optimize wide area network traffic

In one embodiment, a device of a software-defined wide area network (SD-WAN) receives, from a cloud-native application, contextual data for the cloud-native application that identifies microservices of the cloud-native application. The device translates the contextual data for the cloud-native application into a network policy for traffic in the SD-WAN associated with the cloud-native application. The device applies the network policy to a traffic flow in the SD-WAN between an endpoint and a particular microservice of the cloud-native application.

A system for identifying a subscriber includes an access server coupled to a number of subscribers using a first communication network and further coupled to a second communication network, a memory coupled to the access server, and a processor coupled to the memory. The access server receives a communication from a particular subscriber using a particular one of a number of virtual circuits associated with the first communication network. The memory stores path information that identifies a virtual circuit assigned to the particular subscriber. The processor identifies the particular subscriber for connection to the second communication network based upon the path information and the particular virtual circuit used to receive the communication from the particular subscriber.

System and method for identifying a subscriber for connection to a communication network

A system for determining subscriber information includes an access server coupled to a number of subscribers using a communication network, a memory coupled to the access server, and a processor coupled to the memory. The access server receives a communication from a particular subscriber using a particular one of a number of virtual circuits associated with the communication network. The memory stores subscriber information for the subscribers, wherein the subscriber information is indexed by path information that identifies a virtual circuit assigned to the particular subscriber. The processor determines subscriber information for communication to the particular subscriber based upon the path information and the particular virtual circuit used to receive communication from the particular subscriber.

To ensure fair access to upstream trunk bandwidth among a plurality of interface units, a plurality of queues is provided in a first unit. One of the queues is associated with the first interface unit. Each of the remaining queues is associated with one of a plurality of second interface units. Local data is received by the first interface unit and forwarded to the associated queue. Data received from a second, subtended interface unit is forwarded to a queue which associated with the second interface unit. Data is then issued from the queues according to a fairness algorithm. A unique identifier is assigned to each interface unit. Associating a queue with an interface unit is done by associating the queue with the respective interface unit's identifier. In each interface unit, local data is tagged with the instant interface unit's identifier, and received data is forwarded to a queue according to the data's tag. For ATM traffic, data can be tagged by inserting the receiving interface unit's identifier into the generic flow control (GFC) field. Alternatively, a table of associations between virtual channel identifiers (VCIs) and interface unit identifiers may be maintained, and the received data is forwarded to a queue according to the interface unit identifier associated with the data's VCI.
