System Infrastructure
Differently from other experiences, the CISAR group tried to establish a whole infrastructure, made by not only wireless links, but also management and monitoring services in order to guarrantee the right level of quality and availability. On the top of this infrastructure, CISAR is activating several services, from voice and video over IP, DSTAR support and conferencing systems. All the servers are running on virtual VMWare ESXi environment (free), and are based on GNU/Linux Operating System (CentOS distribution). The activation of the dynamic routing protocol OSPF (Open Shortest Path First), has permitted to obtain an high level of overall availability and has candidate the Cisar Digital Network to be the natural solution for digital communication in emergency situations.
CisarNet connection policy
The above infrastructure permits any radio amateurs to connect to the CISAR Digital Networks, without requiring credentials or digital signature. This "guest" access is totally free, fully automatic, broadcasting wireless SSID, assigning DHCP IP address, DNS server IP address with DDNS record update, and easy to try. On the other hand, all the installation fully compliant with the Guide Line becomes integration part of the backbone of the CisarNet.
Published services
The most used service published via CisarNet infrastructure is the live map monitoring that can be found at http://wifi.cisar.it/. We published via Google Map the real time status of all the devices being part of the CISAR Digital Network. On the same web page, you can find the Link to the LogView application where everyone can check the log messages of all devices for first level of debugging and checking. This kind of services are accessible from Internet too and other published services are available only from inside CisarNet. The lastone added service is about Voice over IP project, based on Asterisk/Askotia server, that permit you to monitor the presence status of all VoIP hardware devices, including softphone (most common is 3Cx SIP client software).
IP Addressing Plan
CisarNet as private network mapped to 10.0.0.0/8 IP addresses
CisarNet is considered as a private network using class A IP addressing plan 10.0.0.0/8. The second digit mean the province and there are other indications for subnetting all the class B networks in /24, /28 and /30 subnets, depending on the use (LANMIX, Wireless Poit-to-Point, Wireless Point-to-Multipoint, Tunnel VPN).
CisarNet and supported networks 44.0.0.0/8 of ampr.org
All the 44.0.0.0/8 are transported in native mode (no Network Address Translation is performed) in all Cisar Digital Networks, permitting the full compliance to ampr.org directives. Networks 10.0.0.0/8 and networks 44.0.0.0/8 are fully routed inside CisarNet.
CisarNet and Internet
To be compliant to Italian Law (Codice delle Comunicazioni e Decreto Pisanu), connection from CisarNet to Internet is only possible for radio amateurs aims. DSTAR devices connect to CisarNet are contacting XReflector linked to Internet.
CisarNet, ampr.org and other project's networks interfacing
Interfacing CisarNet to ampr.org
CisarNet is fully compliant to ampr.org directives. Cisar group is maintaining a Cisco gateway con connect all 44.0.0.0/8 networks directly to CisarNet, by means of 3 classes C IP address directly allocated inside italian 44.134.0.0/16 IP space of ampr.org. Below the information directly estracted by IW2OHX Marco's documentation (http://www.iw2ohx.net/Host-ita.pdf), italian coordinator of 44.134.0.0/16 ampr.org addresses.

Interfacing CisarNet to other project's networks
It's working from Septmeber 2010 the wireless direct connection from CisarNet to HamNet (via Alps between Italia and Austria). Thanks to Tobias IW3BRC and to the coordinator of HamNet project Jann DG8NGN. Other contacts are in progress with Spain and Croatia. We could accept wireless connection (see most suitable on the map http://wifi.cisar.it) or via Internet Tunnel (IPIP, GRE, OpenVPN or DMVPN) by means of our Internet public gateway.

Who's CISAR Association (brief)
The Cisar Association (Italian Center for Radio Amateurs Experimentation, http://www.cisar.it), founded in Rome in 1981, is one of the main Italian associations that attract thousands of amateur members throughout the country, with about 50 sections. The president of CISAR Association is Giuseppe Misuri (IW5CGM) of Arezzo, while the headquarters of the association is in Mestre (Venice). It is known in Italy and abroad mainly for two important projects, the National Voice Link and the National Digital Link, which allow you to connect simultaneously to Amateur Radio over most of the country, with a backbone radio links in UHF (430 Mhz) and WiFi Access (2.4 and 5.7 Ghz) which crosses the peninsula and that it can be used with simple hand-held radio devices also. Important Experimentation has been conducted with emerging radio amateur technology DSTAR. All these systems are useful for testing their normal activities of amateur radio operators, have proven crucial in the management of relief activities in an emergency situation.
