To anybody who knows black-scholes model and stochastic differential
equation or anybody who knows control theory.
dS=αSdt+βSdB, S denote the price of a stock depends on t,S(t), α is the
drift or rate of return, β is the volatility, B is brownian motion.
How do I incorporate the control parameter γ , and a number “ L “defined
as dN/dS, where N denotes the amount of asset traded and S denote the asset
price so that dS=(αS+γ/L)dt+βSdB
defines a differential equation.
Thank you in advance

没人对这种OTT架构了解?

This is the kind of thing that the trouble-makers do in program trade.
hahaha

如果没什么特殊要求,一般就是在vendor那儿买个现成的solution吧。
我有个同学在cable公司,最近刚到cisco作培训,准备用cisco的solution在他们公司
提供
IP TV service。
我问了一下,他还说不清楚,似乎用到了mpls l3vpn。

有你这样model SDE的吗?哪里有论文可以查一下?实在是没看懂你的方程。

cable公司这类的IPTV和这俺提到的OTT video还是差别很大的

找本书把stochastic control theory仔细看下,把state and control variable 的意
义弄明白,然后要根据自己研究的东西,写differential equation,,别人整部明白你
想表达的是什么

这问题太大了吧,有几种答案供选择没有?
比如CDN
