farima
解釋
法里馬-
The research of farima model is emphasized due to its linearity and easier access than nonlinear ones
本文的重點放在對farima模型的研究上，因為它是一個線性模型，實現起來更容易一些。 -
Finally, the prediction method of network traffic is proposed. simulations show that farima ( p, d, q ) is effective for long - range dependent network traffic prediction
最後，根據已經得到的farima （ p ， d ， q ）模型，提出了預測未來業務流流量的方法，並通過實際業務量進行了驗證。 -
In long - range dependent case, a 5 - layer bp is applied to predict the network traffic. simulations show that, in terms of prediction, bp is more precise than farima, but at the cost of computing complexity
研究結果表明，該模型能夠較好地預測自相似業務流，特別是在預測精度上比farima模型要高，但是它的計算量較大。 -
Farima ( p, d, q ) model can describe the nature both of shot - time relations and of long - time relations. through the research of fractional calculus, it is found that farima ( p, d, q ) model is essentially a fractional differential, so network traffic control system is a fractional control system
通過對分數階微積分的研究，發現farima （ p ， d ， q ）過程實際上是一個分數階微分模型，因此網路擁塞控制系統是一個分數階控制系統。 -
Firstly, in this paper, the definition of farima model is introduced, and the generating method of farima process is given. simulations have shown that farima process is self - similar. secondly, procedures are given to obtain the three parameters of farima ( p, d, q ) in self - similar network traffic
接著，介紹了利用farima模型進行建模的過程，即根據網路業務流，求解farima （ p ， d ， q ）模型中的三個參數p 、 d 、 q的過程，即farima模型的擬合過程。 -
Moreover, special aspects of self - similar traffic are summarized. for long - range dependent traffic, two prediction models are given and discussed the prediction results can be applied to reduce loss ratio in allocation of memories in network nodes. the first model is farima ( fractional autoregressive integrated moving average )
根據自相似業務流的長相關特性，本文重點討論了兩種數學模型，目的是用這兩種模型對自相似業務流進行預測，進而根據預測結果對計算機網路節點的存儲器資源進行合理的分配，使得丟失率達到最小。
