|
||
|
|
Web server's resources are being overloaded by client requests entering your
|
||
|
|
network. You are asked to slow incoming HTTP traffic to your Web server on
|
||
|
|
the local interface 192.168.1.1. Quality of service (QoS) can
|
||
|
|
help you restrict the accepted inbound connection attempts, based on connection
|
||
|
|
attributes (For example, IP address) to your server. To achieve this, you
|
||
|
|
decide to do an inbound admission policy, which will restrict the number of
|
||
|
|
accepted inbound connections.</p>
|
||
|
|
<p>The figure shows your company and a client
|
||
|
|
company. This QoS policy can only control traffic flow in one direction.</p>

|
||
|
|
configure an inbound policy, you must decide whether you are restricting traffic
|
||
|
|
to a local interface or a specific application and whether you are restricting
|
||
|
|
it from a particular client. In this case, you want to create a policy that
|
||
|
|
restricts connection attempts from Their_Company going to port 80 (HTTP protocol)
|
||
|
|
on your local interface 192.168.1.1.</p>
