The Loria laboratory possess a 1Gbit Ethernet network. Service nodes of the cluster are connected to this network. So the 24-port experiment switch, which connects service nodes, makes the uplink to this network.

Nancy's Grid'5000 cluster is hosted in Loria building. So cabling distance is short. 1000BASE-T technology is used with an RJ-45 CAT6 cable. The 24-port experiment switch is directly linked to the Loria router.

== Addressing ==
 
Loria uses a public IP address range for its materials : <code class="host">152.81.0.0/16</code>. Within this range, the subnet <code class="host">152.81.45.0/24</code> is dedicated to Grid'5000 cluster:
 
* <code class="host">152.81.45.[101-1??]</code> are dedicated to service node first experiment interface
 
* <code class="host">152.81.44.[201-2??]</code> are dedicated to service node management interface
 
 
 
{{Note|text=Service node first experiment interfaces possess 2 IP addresses:
 
* <code>eth0</code> for cluster's intraconnect: <code>172.28.53.[1-X]</code>
 
* <code>eth0:0</code> for Loria's interconnect: <code>152.81.45.[101-1XX]</code>}}
 
 
 
== Naming ==
 
Service node interfaces connected to Loria network are also named on it. These names are gathered into <code class="domain">grid5000.loria.fr</code> subdomain :
 
* <code class="host">fgrillon[1-??].grid5000.loria.fr</code> are dedicated to service node second experiment interface
 
:'''Note:''' <code class="host">fgrillon.grid5000.loria.fr</code>, <code class="host">grillon.grid5000.loria.fr</code> and <code class="host">acces.nancy.grid5000.fr</code> are also used for default service node.
 
* <code class="host">fgrillade[1-??].grid5000.loria.fr</code> are dedicated to service node management interface
