The invention discloses an optical transmission network based cloud platform source collecting accelerating method and system. According to the optical transmission network based cloud platform source collecting accelerating method, a source collecting accelerating engine is added between an optical transmission network based cloud computing platform and an optical network resource, source collecting is that an exterior operation system searches source data in the source collecting accelerating engine and collects the source data from a distribution type source database if the source data is not found from the source collecting accelerating engine when collects optical transmission networks through the cloud platform, and accordingly a high-speed and efficient data collection purpose is achieved.
