Layer-specific modifications may be applied to a network communication received at a proxy according to configurable rules at the proxy. A modification configuration may be received at the proxy that corresponds to a layer of a communication stack supported by the proxy. When a communication is received, data from the layer of the communication stack of the network communication may be evaluated to determine whether a modification is applicable to the communication according to the modification configuration. An applicable modification may be applied by proxy as part of processing the communication at the proxy.

Layer-specific modifications to network communications according to configurable rules at a proxy

A test system includes a controller that creates test jobs to simulate a load for testing a target system or service. The jobs specify test data from a data store. The controller adds the test jobs to a job queue at a rate. Workers access jobs from the job queue and request data from the data store as specified in each job and send the request data to the service. Approximations (e.g., metric values indicating performance of the worker host resources, or performance of the system under test or performance of resources that implement the system under test, other feedback, etc.) of actual system characteristics such as the actual number of workers are obtained. Based on the metric values, the controller modulates various characteristics of the load generation system, such as a rate at which jobs are added to the job queue or the number of workers processing jobs.

A system may implement a flexible architecture to allow designers and testers to use a single flexible system for testing during a transition from a computer simulated model to a physical working prototype via a bus (or protocol). As hardware components become available, the system may be updated to enable replacing a simulated component with a physical hardware component while continuing to leverage at least some existing parts of the system (e.g., software and/or hardware components including simulation). The system may use customizable application program interfaces (APIs) to interface with the different components, simulated or physical. The APIs may enable components to be 'plugged in' to the system to create a different configuration. In some embodiments, API's and/or other simulation data may be stored in a library to enable reuse or modifications at different times.
