Protocol-aware Cloud Gateway with Adaptive Rate Control

As cloud computing has emerged as the next-generation architecture for IT enterprises, it is challenging to envision a well-configured cloud environment that delivers services without adequate mechanisms for maintaining high availability, minimizing latency, and ensuring robustness. A notable feature of distributed cloud systems is their need to support a wide range of data formats and communication protocols. The pivotal role of communication protocols in facilitating seamless interactions among distributed components depends on their capability to perform real-time data and protocol conversion, ensuring interoperability without data loss while considering latency and reliability constraints. This paper proposes a prototype of open-source components designed to enhance distributed cloud infrastructure, including a protocol-aware gateway that performs configurable protocol transcoding. Additionally, the gateway component is connected to a rate-limiting service that ensures high availability and mitigates network congestion. These components are seamlessly integrable, preserving protocol features without performance trade-offs. Their effectiveness is demonstrated through integration into the open-source Constellations (C12S) platform, validating their flexibility and practical value in real-world cloud environments.
