According to the definitions of bottleneck bandwidth, available bandwidth and bulk transfer capacity, we analyzed the algorithms which named vps ( variable packet size ), pptd ( packet pair / train dispersion ), slops ( self - loading periodic streams ) and topp ( trains of packet pairs ) ; based on the principle of sub - path bottleneck measurement, we developed the bottleneck measurement algorithm using heterogenous packet - pair train ; after designing the three child algorithms ( demarcating bandwidth range, approaching bandwidth value and predicting the trendency of available bandwidth fluctuation ), we performed the algorithm called self - loading binary search ; applying the multi - home properties of sctp ( stream controltransmission protocol ) and measurement algorithm of available bandwidth, we presented a scheme to adjust the sctp transport path when there are network congestions or faults ; by the library of winsock and winpcap, we developed a measurement program to look for bottleneck bandwidth. in ns2 experiments, the algorithm based on heterogenous packet - pair train fitted well, and the algorithm of self - loading binary search worked quickly, and the sctp scheme improved the throughput effectively

Differentiated from the former markers, afm neither aims at some certain factors, nor tries to establish a precise mathematic model. on the contrary, afm follows a rule of result - oriented and reallocates the network resources in an adaptive manner, and thus gains high performance in the fairness of bandwidth sharing ; 3 ) the congestion control mechanisms of the current tcp have been proved to be effective for prevention of network collapse. however, with the development of network technologies, the insufficiencies of tcp are becoming increasingly severe, especially in the environment of heterogenous networks, the throughput performance of tcp is disappointing

與以往的標記演算法不同的是，該演算法並不針對具體某一個因素對公平性的影響，也不試圖建立一個精確的數學模型，而是按「結果導向」以一種自適應的方式來對可用的網路資源進行重新分配，從而獲得很高的公平性； 3 ） tcp協議的擁塞控制機制已經被證明能有效地防止網路崩潰的發生，但隨著網路技術的發展， tcp協議的一些局限性也已經暴露出來了，尤其是在異構網路環境下，其吞吐量性能表現令人堪憂。
