-It creates two sockets to bypass the TCP/IP packets among the fix console 
-server specified at class construction (console_host, console_port)

+openmano server.
+Main program that implements a reference NFVO (Network Functions Virtualisation Orchestrator).
+It interfaces with an NFV VIM through its API and offers a northbound interface, based on REST (openmano API),
+where NFV services are offered including the creation and deletion of VNF templates, VNF instances,
+network service templates and network service instances. 
+
+It loads the configuration file and launches the http_server thread that will listen requests using openmano API.

-'''
-openmano server.
-Main program that implements a reference NFVO (Network Functions Virtualisation Orchestrator).
-It interfaces with an NFV VIM through its API and offers a northbound interface, based on REST (openmano API),
-where NFV services are offered including the creation and deletion of VNF templates, VNF instances,
-network service templates and network service instances. 
-
-It loads the configuration file and launches the http_server thread that will listen requests using openmano API.
