A customizable router manages traffic between application programming interfaces (APIs) of microservice applications (apps) that make up various features of a website. Various datastores may also be used to store information, such as information related to certain products, pricing, users, etc. In order for the website to function properly, the microservice apps communicate with one another and with the datastores. The customizable router is used to manage and route traffic between the microservice apps and/or datastores. The customizable router may, for example, route a universal resource indicator (URI) request for a webpage of a website to particular versions or revisions of a microservice app based on rules established for the customizable router. For example, a certain percentage of traffic may be routed to a first version of a microservice app, while a different percentage of traffic may be routed to a second version of the microservice app.

A network performance measurement method includes a first network device that sends a first active measurement protocol packet to a second network device, where the first active measurement protocol packet includes measurement indication information, where the measurement indication information indicates a measurement device on a forward path to measure network performance. The forward path is a forwarding path of the first active measurement protocol packet, and the first network device and the second network device are two ends of the forward path, and the measurement device on the forward path includes at least one intermediate device on the forward path. The intermediate device measures network performance of the forward path

In various embodiments, a network emulation application emulates network conditions when testing a software application. In response to a request to emulate a first set of network conditions for a first client device that is executing the software application, causing a kernel to implement a first pipeline and to automatically input network traffic associated with the first client device to the first pipeline instead of a default bridge. In response to a request to emulate a second set of network conditions for a second client device that is executing the software application, causing the kernel to implement a second pipeline and to automatically input network traffic associated with the second client device to the second pipeline instead of the default bridge. Each of the pipelines perform one or more traffic shaping operations on at least a subset of the network traffic input into the pipeline.

Disclosed are techniques to regenerate SYNC bits of a High-Speed data packet lost by the transmission envelope detector of a repeater/hub that interconnects electronic devices compliant with Universal Serial Bus (USB) Specification Revision 2.0 or higher. A physical layer logic (PHY) of a first port of the repeater/hub receives a High-Speed data packet to store a recovered bit stream into an elastic buffer. The recovered bit stream may lose some SYNC bits at the beginning of the SYNC pattern. The repeater/hub reads the recovered bit stream from the elastic buffer for transmission through the PHY of a second port. If the end of the SYNC is read before a programmable number of SYNC bits have been transmitted, the repeater/hub generates additional SYNC bits for transmission until the programmable number of SYNC bits are transmitted. The repeater/hub then resumes transmitting the rest of the High-Speed data packet starting from the payload.

The disclosed scoring uses a “dynamic packet loss threshold” that is based on benchmarks of “good” packet loss behavior of network paths associated with circuits of different bandwidths and recent behavior of the path being scored. The observations for good packet loss behavior are bucketized by corresponding circuit load. For the path being scored, observations are also bucketized and aggregated into a moving average per load bucket. The moving averages represent recent behavior of the path by load bucket. The scoring system scores a path as a function of the current time interval packet loss of the network path being scored and the dynamic packet loss threshold of the current time interval. The dynamic packet loss threshold of the current time interval is a function of a good packet loss benchmark and the packet loss moving average for the load of the current time interval.
