+ANNEX A: Use case for OPNFV Brahmaputra
+=======================================
+
+A basic resource reservation use case to be realized for OPNFV B-release may
+look as follows:
+
+* Step 0: Shim-layer is monitoring/querying available capacity at NFVI
+
+ * Step 0a: Cloud operator creates a new OpenStack tenant user and updates
+ quota values for this user
+
+ * Step 0b: The tenant user is creating and instantiating a simple VNF
+ (e.g. 1 network, 2 VMs)
+
+ * Step 0c: OpenStack is notifying shim-layer about capacity change for
+ this new tenant user
+
+ * Step 0d: Cloud operator can visualize the changes using the GUI
+
+* Step 1: Consumer(NFVO) is sending a reservation request for future use to
+ shim-layer
+
+* Step 2: Shim-layer is checking for available capacity at the given time
+ window
+
+* Step 3: Shim-layer is responding with reservation identifier
+
+* Step 4 (optional): Consumer(NFVO) is sending an update reservation request
+ to shim-layer (startTime set to now) -> continue with Steps 2 and 3.
+
+* Step 5: Consumer(VNFM) is requesting the allocation of virtualised resources
+ using the reservation identifier in Step 3
