A Transmission Method Based on Learning Energy Efficiency Model

Abstract

The invention discloses a transmission method based on a learning energy efficiency model. Firstly, the historical change trend of the network is periodically recorded, the round-trip time delay is weighted and smoothed, and the change trend of the congestion control window is judged; then the network energy efficiency and Congestion control window modeling, whenever a new ACK is received, the energy efficiency window model is updated; finally, combined with the congestion window and energy efficiency change trend, the congestion control window size for the next period is predicted; for network packet loss or timeout events, use In the traditional TCP packet retransmission mechanism, after the packet loss is over, the energy efficiency model is used for processing. The present invention reduces the impact of network random events and traditional algorithm estimation errors, and can balance the emphasis on delay and throughput; in high-speed networks, it can approach higher link bandwidth occupancy and lower end-to-end Delay, which reduces the end-to-end delay experienced by data packet transmission.

Description

technical field [0001] The invention relates to the field of Internet end-to-end reliable transmission, in particular to a transmission method based on a learning energy efficiency model oriented to high-bandwidth and long-delay networks. Background technique [0002] With the continuous development of computer networks, the improvement of users' requirements for service quality and the continuous popularization of broadband network access, more and more high-bandwidth links will be applied to the Internet. The rapid increase of network bandwidth, satellites with high delay and the increase of multi-hop wireless links have caused some backbone networks in the Internet to have both high bandwidth and high delay characteristics, forming a high bandwidth delay product (High Bandwidth Delay Product, HBDP )The internet. In the case of increased single-flow bandwidth-delay product, the effectiveness of the congestion control mechanism for network transmission must be maintained. ...

Problems solved by technology

The Verus protocol does not accurately detect the network state, but establishes a short-term model for the delay and window relationship to adjust the window. This method can be applied to the environment where the network state cannot be accurately controlled (such as the delay is unstable), but Not as good as UDT in terms of bandwidth utilization
