a few of the products provide policy based networking capability,
in that sense you can have a centralized server to distribute the
network policy. But guess the admin work is always there
For IPSec SA using IKE? it varies, deciding factors can be computing power,

题目如下：
The purpose of this problem is to show that solving linear programming
problems is no harder than solving systems of linear inequalities.
Suppose that we are given a subroutine which, given a system of linear
inequality constraints, either produces a solution or decides that no solution
exists. Construct a simple algori |

发帖数: 1035 | 11 depends on how complex the control algorithm. the interrupt can be set at an
y rate but overrunning the cpu is common problem. Of course, cpu itself, fix
pt vs. float, ram vs flash etc. are relavent factors. position commanding i
s usually simple as a pid. but something like sensorless observer with highe
r order of number of states may easily increase the complexity of the algori
thm.
an easy question to ask is how many states do you have, and what integration
method do you choose. |

发帖数: 925 | 12 一般工业上应用的motion control貌似没这么复杂，只是一些特殊场合的才会这样去做吧
而且，现在的大部分motion control都是用的电机反馈做的半闭环和简单的pid
可能你做的系统比较高端。
