=== Multirate ===
A multirate service network is one which flexibly allocates transmission capacity to connections. A multimedia network has to support a broad range of bit-rates demanded by connections, not only because there are many communication media, but also because a communication medium may be encoded by algorithms with different bit-rates. For example, audio signals can be encoded with bit-rates ranging from less than 1&nbsp;kbit/s to hundreds of&nbsp;kbit/s, using different encoding algorithms with a wide range of complexity and quality of audio reproduction. Similarly, full motion video signals may be encoded with bit-rates ranging from less than 1&nbsp;Mbit/s to hundreds of&nbsp;Mbit/s. Thus a network transporting both video and audio signals may have to integrate traffic with a very broad range of bit-rates.<ref name=Hui/><ref name=QoS/>
