<h1 class="topictitle1">Average connection rate and burst limits</h1>
<div><p>Connection rates and burst limits, together, are known as <em>rate
limits</em>. These rate limits help restrict inbound connections trying to
enter your server. Rate limits are set in a class of service used with inbound
admission policies.</p>
<div class="section"><h4 class="sectiontitle">Connection burst rate</h4><p>The burst rate size determines
the buffer capacity, which holds connection bursts. Connection bursts might
enter the server at a faster rate than it can handle or that you might want
to allow. If the number of connections in a burst exceeds the connection burst
rate you set, then the additional connections are discarded.</p>
</div>
<div class="section"><h4 class="sectiontitle">Average connection rate</h4><p>The average connection rate
specifies the limit of new, established connections or rate of accepted Uniform
Resource Identifier (URI) requests allowed into a server. If a request causes
the server to exceed the limits you set, the server denies the request. The
average connection request limit is measured in connections per second.</p>
<div class="tip"><span class="tiptitle">Tip:</span> To determine what limits to set, you can run the monitor. The scenario
about monitoring current network statistics contains a sample policy that
might help you collect most data travelling on your server. Using these results,
you can adjust the limits appropriately.</div>
<p>To view real-time monitor
data instead of a particular data collection, open the monitor. The monitor
gives real-time statistics on all active policies.</p>
