What is a NAP?
A NAP is a physical space where the networks of Internet operators are interconnected; it allows to optimize this fundamental activity of "cooperative coexistence" .
Back to topWhy a NAP?
A NAP contributes to rationalize the mesh structure of the Internet. As itallows local routing of the traffic that is not addressed to others than NAP participants, it allows any participants to reduce their long-distance communication resources needs. Furthermore a mesh structurehas a greater resilience against accidents/attacks.. For these reasons a NAP in the Veneto Region improves the overall organization of the Internet at regional level, making it insensitive to any accidents occurring in other areas.
Back to topWhy in Padua?
Most local and national operators have chosen for a long time to locate in Padua the coordination structure for North-East; it would then be less efficient to place the NAP in another area.
Back to topWhy integrating RUPAR in the NAP?
The integration of the PA (Public Administration) in the NAP allows a wider integration of the PA within the information society, thus increasing the number of potential efficient users and/or suppliers of the PA locally.
Back to topWhat is an AS?
An Autonomous System (AS) with reference to routing protocols, is a group of routers and networks under control of a single well identified administrative authority. An Administrative authority is characterized by both information/computer features (specific routing policies)and administrative reasons. An example of autonomous system can be the one that characterizes the users of a single provider or, on a smaller scale, the one that constitutes the inner networks of an enterprise. In an autonomous system routers communicate with each other to exchange information on the creation of routing tables, through an IGP (Interior Gateway Protocol). Interexchange of information among routers belonging to different autonomous systems happens by means of BGP (Border Gateway Protocol). The ASs using public IP addressing have to be registered to authorities in charge (the so called RIR), such as: RIPE, LACNIC, AFRINIC, ARIN.
Back to topWhat is a RIR?
A Regional Internet Registry (RIR) is an organization that superintends the assignment and the registration of Internet number resources in a specific area. In particular the assignment of IP addresses, necessary to add new nodes to the net and fundamental for its functioning. Five registries currently exist worldwide, each competent for an area:
- AfriNIC (African Network Information Centre) - Africa
- APNIC (Asia Pacific Network Information Centre) - Asia and Pacific Ocean
- ARIN (American Registry for Internet Numbers) - North America
- LACNIC (Regional Latin-American and Caribbean IP Address Registry) - Latin America and Caribbeans
- RIPE NCC (Réseaux IP Européens) - Europe, Middle East and Central Asia
What is a OVER Network?
Per rispondere alle nuove esigenze di connettività è stata creata una infrastruttura di rete che, poggiandosi sulle connessioni Internet realizza collegamenti criptati, sicuri ed affidabili.
OVER Network rappresenta un alternativa ai collegamenti punto punto e alle reti MPLS (Multi Protocol Label Switching) generalmente utilizzati per implementare le intranet aziendali.
E' la via di accesso ai servizi pubblicati nella Infranet del Sistema Pubblico di Connettività alla quale sono connessi le Amministrazioni Centrali Locali.
Non prevede la posa di fibra nè il suo finanziamento, ma utilizza l'infrastruttura esistente di cui dispongono gli ISP (Internet Service Provider).
Realizza un sistema multiprovider servendosi del NAP (Neutral Access Point) del Nord-Est.
Si estende sul territorio della Regione del Veneto con lo scopo di costruire la Community Network Regionale, che è un luogo di incontro, consultazione e scambio tra i vari entri che vi partecipano che possono anche pubblicare dei propri servizi.
Un partecipante al VSIX, per essere inserito nell'elenco Elenco degli Internet Service Provider accreditati ad OVER network, deve compilare e inviare l'opportuno modulo, con tutti gli allegati a paola.bregolato@unipd.it
Il modulo è reperibile nella sezione moduli.
Back to topVSIX-TOPIX interconnection
The experimental VSIX-TOPIX interconnection is operative since October 2009.
This connection geographically extends both VSIX and TOP-IX public peering LANs and allows members of the two IXs to set up public peering agreements in an interregional domain to benefit from related services. This initiative is meant to be an incentive for all, in order to offer a better quality service.
In order to benefit from this opportunity, the interconnection between the VSIX participant' s Border Router and the NAP core switch has necessarily to be implemented by means of a trunk 802.1 transposing the VLAN 222 (VS-IX public peering) and the VLAN 4 (public peering TOP-IX).
Those who do not have these requirements will have to agree the change in their network configuration writing to staff@vsix.it.
After that, a VSIX member will be enabled to ask for a IPv4 TOP-IX address writing to networking@top-ix.org.
This address will be used on the VLAN 4 as address for public peering with TOPIX members.
In the same way, by sending the form to staff@vsix.it, TOP-IX members will be able to require a IPv4 VS-IX address and the password to enter the members' area of the website www.vsix.it.
