+The Distribute Traffic LCM action is used to distribute traffic across different instances of VNF, VNFC or VM.
+The entity for which Distribute Traffic LCM action is being invoked is called an anchor point that is responsible for final
 realization of request. Parameters present in configuration file specify where and how traffic should be distributed,
 including: traffic destination points like VNFs, VNFCs or VMs; distribution weights; rollback strategy.
 Format of configuration file is specific to each VNF type.
