            <title>[SERVER-8148] Implement Phi Accrual Failure Detection for detecting Node Failure</title>
                <link>https://jira.mongodb.org/browse/SERVER-8148</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;I did some reading on how Cassandra does its internal checking and it implements a phi-accrual detection algorithm which is more sensitive to dynamic network conditions than a simple heartbeat. It also provides a scalar failure measurement instead of a binary yes/no detection which allows for configuration of tolerance levels.&lt;/p&gt;

&lt;p&gt;See:&lt;br/&gt;
&lt;a href=&quot;http://ddg.jaist.ac.jp/pub/HDY+04.pdf&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://ddg.jaist.ac.jp/pub/HDY+04.pdf&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;There are pros/cons (particularly around simplicity), but I&apos;d be curious what you at 10gen think about the appropriateness/usefulness of basing your failure detection off of this kind of a protocol.&lt;/p&gt;</description>
