摘要: | Delay-based TCPs detect network congestion in the early stage and successfully prevent periodic packet loss that usually occurs in loss-based mechanisms. It has been demonstrated that delay-based algorithms outperform loss-based schemes in many aspects. However, a delay-based TCP may not prevent unnecessary throughput degradation when rerouting occurs and in mobile IP networks and mobile ad hoe networks because it could not differentiate whether the increased RTT is due to route change or network congestion. This work investigates how to improve the performance of delay-based TCPs with rerouting and proposes a mechanism for delay-based TCPs. The proposed mechanism is able to re-measure the BaseRTT if necessary by detecting the change of TTL value of two end-hosts. Based on the simulation results, we demonstrate the effectiveness and utilities. |
