hello all :
We have a functional requirements。 Suppose you have two card in one bridge,
such as vnet1.0, vnet2.0 。
Through to the network adapter configuration parameters of a priority, such as
vent1.0 is 50, vnet2.0 100。Then the ratio of vnet1.0 and vnet2.0 is 50:100 =
1:2 。 We hope to allocate bandwidth of those adapter by ratio 。For example, if
we under gigabit network , we see bandwidth of vnet1.0 is 333 Mb/s , and
vnet2.0 is 666Mb/s。Of course, the premise is a network card contract can be
close to 1000 Mb/s.
If the vnet2.0 stop contract , now the vnet1.0 able to advantage of all the
bandwith (1000Mb/s) .
In a nutshell, In the network close to the congestion, according to the
allocation of bandwidth ratio. Conversely, if physical bandwidth not congested
, all virtual netcrad can be contracted out freely.
We tried to realize based on the TC, tc can only be limit bandwidth but
cannot be preempted. We must have in order to realize the project requirements.
Are there ready-made solutions ?
