There are two different schemes to implement the abr service congestion control , binary rate feedback ( brf ) scheme and explicit rate feedback ( erf ) scheme Abr業(yè)務(wù)采用基于速率反饋的擁塞控制機(jī)制,主要有兩種實(shí)現(xiàn)方案:二進(jìn)制速率反饋和顯示速率反饋方案。
According to a max _ mm fairness standard , this paper proposes an explicit rate calculating abr flow control scheme which satisfies vcs ’ requests as possible as it could . it is a rate _ based method 這是一種基于速率的流控方法,能最大限度的滿足vc的帶寬請求,提高了信道使用率,具有公平性。
Commonly , real - time network applications use udp to transmit data in constant rate , which may affect the performance of the other transmissions such as tcp connections , and result in severe network congestion . to solve this problem , this thesis proposes a new udp congestion control scheme basing on explicit rate , which is tcp - friendly 提出了一種tcp友好的、基于顯式速率的udp擁塞控制策略:通過端主機(jī)和網(wǎng)絡(luò)中的路由器相互配合,使得實(shí)時(shí)udp應(yīng)用能夠根據(jù)網(wǎng)絡(luò)的反饋以瓶頸鏈路的公平帶寬為速率發(fā)送數(shù)據(jù)。
