Abstract: A high-goodput data network architecture and key technologies for the high-performance transmission requirements of complex interactions between intelligent computing and large-scale data are proposed. To solve the high cost and poor transmission timing in traditional dedicated networks, the high-goodput data network improve the data transmission volume per bandwidth unit. By adopting key technologies such as wide-area flow scheduling, intelligent operation administration and maintenance, transport protocol optimization, data compression and security, elastic bandwidth allocation of the network is achieved and network transmission efficiency as well as goodput is improved. The transmission measurement of large-scale data over 3 000 km carried out in the existing carrier network to verify the feasibility of the high-goodput data network architecture and key technologies.
