Heuristic based authentication protocol for stateless protocol
Heuristic based approach to authentication of requests in a stateless protocol environment. Heuristics may be applied to a request to calculate a trust level for the request. The trust level for a request may at least in part be based on request parameters for the request and one or more previously received requests in a user context profile. Thus, historical request metadata may be used in calculating a trust value of a received request. If the trust value for a request exceeds a trust threshold, the request may be authenticated without forwarding the request to an authentication server. Thus, for requests in which the trust value exceeds the trust threshold, system performance may be improved by not requiring computational overhead and/or network bandwidth to be used in authentication. In this regard, the format of the request may still comport with the stateless protocol, but authentication may be made more efficient. |

Latency measurement techniques in a low latency environment
Latency of a gateway system that connects to downstream services can be measured using an external computer system. The gateway may route component requests to various downstream services in order to service a main request, and be part of an overall service where low latency is important. It may be desirable for the gateway system to have as little added latency as possible. Benchmarking the gateway by performing latency measurements can give an indication of how the gateway is performing. If software on the gateway changes, re-benchmarking the gateway can reveal if problematic code was introduced. A measurement system can employ a lightweight process so that minimal additional latency is incurred by the measuring process. Memory can be allocated as to avoid a garbage collection process so that the latency measurement is unaffected when garbage collection occurs, for example, and multiple buffers can measure latency for different request types. |
