The basic thought of the csapfba algorithm is : the edge routers perform the state management per flow, and the edge routers differentiate between the marked flows and the non - marked flows, and the edge routers insert the relevant information into the packet header by using dynamic packet state ; the core routers divide the output link bandwidth into two parts in the light of the state information of the packet header by using class - based queueing, and the core routers allocate proportionally the bandwidth to the marked flows according to their service profiles and the current network load, and the core routers allocate the bandwidth to the non - marked flows according to the principle of max - min fairness, and the csapfba algorithm can adaptively dynamically adjust the bandwidth allocation between the marked flows and the non - marked flows
本文在csfq演算法的基礎上，提出了一種核心無狀態的自適應的成比例公平帶寬分配csapfba （ core - statelessadaptiveproportionalfairbandwidthallocation ）演算法。 csapfba演算法的基本思想是：在邊界路由器完成基於每個流的狀態處理，將所有的流分成標記流和非標記流兩種類型，採用dps技術將有關信息編碼進分組頭；在核心路由器根據分組頭中攜帶的狀態信息採用cbq策略，將輸出鏈路帶寬分成兩部分，對標記流根據當前的網路負荷按照服務規格成比例地分配帶寬，對非標記流按照最大最小公平性原則分配帶寬，並且能自適應地動態調整帶寬分配的比例。 -

Attempting to use eapol in a shared medium environment that does not support the use of secure associations renders port - based network access control highly vulnerable to attack ; for example, station a can mount a successful denial - of - service attack on station b simply by issuing an eapol - logoff packet using station b s individual mac address. " see ieee 802. 1x specifications, page 21, section 7. 9, lines 34 - 39, available to link to in the
在不支持使用安全關聯的共享媒體環境中進行使用eapol的嘗試會導致基於埠的網路訪問控制極易受到攻擊；例如，工作站a只要發出一個使用工作站b的個體mac地址的eapol - logoff包，就能夠在工作站b上掛裝一個成功的拒絕服務攻擊。 」 -
