3 SVP Supervision Program (SVP) is a general procedure for management and control as well as a methodology valid and applicable in every point (or node) of the HF network. This program contains the common concepts adopted for the protection of maritime CI in the context of the Mediterranean Sea. It also deals with the common technical requirements for the data/voice communication (radio electric parameters, network and data protocol, etc.) 3SWING Final Meeting | CNIT - Pisa, Italy13/12/2013

5 DSVF Distributed Supervision Functions (DSVFs) follows the general procedure established by SVP. It is a program that runs in every HF network point (or critical infrastructure). It resides in the workstation (PC) to manages the fully reconfigurable hardware that constitute the transmitting/receiving stations. The system is based on the Software Defined Radio technology. Among the various techniques the USRP or Universal Software Radio Peripheralof Ettus has been employed. DSVP contains routine for internet check, activation/deactivation of the network and frequency management. 5SWING Final Meeting | CNIT - Pisa, Italy13/12/2013

16 NETWORK TOPOLOGY 16SWING Final Meeting | CNIT - Pisa, Italy13/12/2013 ECI CGA Link Contention based scenario (DCHF). ECI CGA Link ECI-CGA Token logical ring Local HFTP Each node that needs to transmit waits for token reception. Upon receiving the token, it is allowed to try to transmit its packet for a limited time interval before releasing the token. Every transmitting node senses the channel and then establishes a connection with the receiver
