In line with the development trend of deep integration of energy transformation and information technology, the power network will enter the digital era of the Internet of Everything. With the large increase in power IoT equipment, new business needs such as real-time collection, low latency, and remote operation and maintenance have emerged, and the mainstream protocols of the Industrial Internet of Things cannot fully adapt to the proprietary protocols of various power specialties, and it is difficult to meet the access requirements of the Power Internet of Things. Google's Bottleneck Bandwidth and Round-trip propagation time (BBR) has attracted widespread attention and research because of its high bandwidth utilization and low latency. Based on the BBR congestion control algorithm, this paper proposes a high-performance multi-protocol access technology to realize the cloud protocol gateway that supports million-level long-term connection access, hot-loading plugin mechanism, and multi-protocol communication plugin. As a pre-communication component of the IoT management platform, it is tailored for terminals in the power industry, providing MQTT, CoAP, HTTP, DL/T698.45 and other industry protocol resolution services, and can support intelligent terminals such as intelligent terminals, energy controllers, and energy routers to easily migrate to the cloud.
