A method for suppressing disorderly scheduling in multipath transmission scenarios using time delay offset

Abstract

Multipath transmission enables packets to be distributed over different paths for transmission, andthis method has made full use of individual link resources. However, most existing multipath transmissionschemes lack suitable scheduling mechanisms and suffer from high disorder and packet loss.To address the disorder problem, this paper designs a delay offset method combined with link rejectionor adaptive delay adjustment mechanism to suppress the packet disorder problem in multipathtransmission scenarios based on an in-depth study of the background related to multipath transmission.Finally, a multipath link topology is built on the P4 simulation platform to implement the abovemethod in code simulation, and the experimental results are compared and analyzed with other twoscheduling mechanisms. The experimental results show that this method maintains the disorder levelwithin 5% compared with the single-path transmission and the equivalent multipath method, but thetransmission bandwidth is increased by nearly two times.
