Abstract: This paper analyzed several algorithms when transmitting data in multi homed scenarios and proposed a fast SACK scheme based on multi homed SC,'TP. The scheme eliminate abuse that only the sender grasps the link status. Simulation results show that the proposed scheme could improve the throughout perfommnce of multi-homed SC于hosts when the delay of two paths is not balanced.
