System for enhancing long-distance network transmission quality, method and computer readable medium thereof

Abstract

This invention discloses a long-distance network transmission quality optimization system and method. The system collects user traffic information and cloud platform messages from connected cloud platforms through a service status management subsystem. When user traffic information fails to meet regulatory standards, a correction request is generated. Then, an accelerated network interface card (NIC) management subsystem receives the correction request and cloud platform messages from the service status management subsystem, analyzes the traffic packets, and performs performance adjustment in case of service performance anomalies and / or performs abnormal transmission correction when packets are lost. Accordingly, this invention enables each service to perform its performance effectively and stably. This invention also provides a computer-readable medium for performing the method of this invention.
