1, as a netlimiter speed limit, I don't know how much the minimum limit can be ~ ~ If it can only reach 1%, it will be useless!

2. Use the network management switch, but not the speed limit, but the number of connections. It is best to limit the maximum number of connections per port to 20, 10! The speed can be unlimited, if the feeling card can be limited. However, with your budget, it is difficult to estimate 700, and the configuration of the switch is also a hassle. Very professional ~ ~ compromise method changes the maximum number of connections of five computers (XP system) to 10~

3, there is no solution to using the router, because you use a single cat and multiple accounts for multiplexing dial-in login. At present, we haven't seen that 700-size routers support multiplexing dialing, and campus networks mostly use DR.COM login mode, which is even more difficult ~ ~
