+== 1) Functional Description ==
+
+In a clusterized architecture, clusters are connected to the global interconnect by RingGateways. One RingGateway component is attached to one ring interconnect. This hardware component is composed of two components :
+
+ * [wiki:Component/HalfGatewayInitiator HalfGatewayInitiator] : handles incoming commands and outcoming responses. 
+ * [wiki:Component/HalfGatewayTarget HalfGatewayTarget]       : handles outcoming commands and incoming responses. 
+
+== 2) Component definition & usage ==
