The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols.
Static routes have advantages and disadvantages as compares to dynamic routes.
Advantages of Static Routes
Static routes are easier to configure
No need for overhead on the routing protocol
As long as you have a tight IP mask, this offers you reliable security
Disadvantages of Static Routes
In order to make changes in the network, you have to manually configure the route
When network outage is experienced, it does not automatically route around
Although this is quite easy to configure, it might not work for large and complicated networks
It is important that any network administrator have substantial knowledge about static routes. Although this type of
route may not be as effective with large networks, they are quite useful in any size of networks. Meanwhile, even if
you have setup a dynamic route, there are cases that still require a static route.

QoS(Quality of Service) refers to both a network’s ability to deliver data with minimum delay, and the networking
methods used to control the use of bandwidth. Without QoS, all traffic date is equally likely to be dropped when the
network is congested. This can cause a reduction in network performance and mark the network inadequate for
time-critical application such as video-on-demand.
QoS ( Quality of Service) is to decide which PCs can get the priorities to pass though VPN Router once if the bandwidth
is exhausted or fully saturated.
