The &amp;#039;&amp;#039;&amp;#039;Japan Network Access Point&amp;#039;&amp;#039;&amp;#039; (&amp;#039;&amp;#039;&amp;#039;JPNAP&amp;#039;&amp;#039;&amp;#039;) is an [[Internet Exchange Point]] situated in [[Tokyo]] and [[Osaka]], [[Japan]].&amp;lt;ref&amp;gt;{{cite web |title=The Japan Earthquake: the impact on traffic and routing observed by a local ISP |first=Kenjiro |last=Cho |first2=Cristel |last2=Pelsser |first3=Randy |last3=Bush |first4=Youngjoon |last4=Won |url=https://www.iijlab.net/~kjc/papers/1569500743.pdf |date=December 6, 2011}}&amp;lt;/ref&amp;gt;  JPNAP was established on 2001 and operated by [[Internet Multifeed Co.]]&lt;br /&gt;
&lt;br /&gt;
JPNAP is [[List of Internet Exchange Points by size|one of the largest Internet Exchanges in the world]], by traffic. JPNAP provides 10 [[Gate equivalent|GE]], GbE, FE interfaces and also provides [[Link aggregation]].  The [[Tokyo]] and [[Osaka]] sites are approximately 500km apart, but they are not connected.  JPNAP network is already [[IPv4]]/[[IPv6|v6]] [[Dual-stack]]ed. However, they also provide [[IPv6]]-only service through their [[Internet Exchange Point]] called JPNAP6.&lt;br /&gt;
&lt;br /&gt;
== Technology ==&lt;br /&gt;
JPNAP has two distinguishing features : the first is &amp;quot;Automatically switched optical patch panel&amp;quot; and the other is &amp;quot;PeerWatcher&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
When the &amp;quot;automatically switched optical patch panel&amp;quot; finds a failure in the [[Internet Exchange Point|IX]] switch, it switches patch cable to the other IX switch automatically.  Even if the patch panel has power problems, there&amp;#039;s no effect on the communication, except for the detection of IX switch status.&lt;br /&gt;
&lt;br /&gt;
&amp;quot;PeerWatcher&amp;quot; shows a graph of the traffic between the two BGP routers faced on JPNAP network using [[sFlow]].&lt;br /&gt;
