7-51 <strong>Chapter</strong> 7 - <strong>Memory</strong><br />

Associative <strong>Memory</strong> in Routers<br />

• A simple network with<br />

three routers.<br />

• The use of associative<br />

memories in high-end routers<br />

reduces the lookup time by<br />

allowing a search to be performed in a single operation.<br />

• The search is based on the destination address, rather than the<br />

physical memory address.<br />

• Access methods for this memory have been st<strong>and</strong>ardized into an<br />

interface interoperability agreement by the Network Processing Forum.<br />
