HBONE is the backbone (computer) network of NIIF or Hungarian Academic Community. HBONE delivers services to Hungarian universities and colleges, primary and secondary schools, research and development institutions, libraries, public collections and also to several other non-profit public institutions. HBONE is a separate (telecommunication) network with a closed user-base. HBONE consists of the versatile core, and also the regional center (PoP) routers connected to core routers (directly or indirectly). In the PoPs NIIF operates versatile and robust communication equipments (DWDM, router, switch), servers and other devices required to serve other NIIF services in a climatised and UPS protected environment.
Previous generation of HBONE
The bandwidth of the previous generation HBONE main country and Budapest lines and also the international connections was 10 gigabit/s. The bandwidth of the other connections was characteristically 1 gigabit/s and there are also some lower speed connections in the backbone network. The backbone lines are mainly rented connections from telecommunication services, some fraction was working through connections owned by academic community institution (optical lines, microwave equipment). DWDM technology introduced in 2001 in Hungary, which was first used to serve the demands of the HBONE by Hungarian telecommunication services in Hungary.
Current generation of HBONE (HBONE+)
The new generation of HBONE (under the code name HBONE+), which was set to run in 2010, represented and technological leap forward. This is not only an IP network, but an hybrid infrastructure, which made available both the DWDM and IP layer for the users. The circuits was based on leased optical fibres (dark fibre, DF). These fibres was lit by DWDM systems (Alcatel-Lucent 1830 PSS DWDM systems) operated by NIIFI. This DWDM layer allows flexibility and capacity extensability on demand. This also enables implementing the advanced hybrid network services, which is common among the European NRENs (National Research and Educational Network) and also available in GéANT network. The hybrid network allows the transmission of multiple simultaneous communications channels (currently up to 100 Gbps/channel) over a single optical fibre (Currently HBONE+ uses 10, 40 and 100 Gbps lambdas). In the new HBONE+ the hybrid network (the DWDM layer also) available at the users (nniversitities, research centers), which make HBONE+ unique from the traditional telecommmunication networks. This can allow completly new type of services like Science DMZ. On top of the DWDM layer Ethernet IP/MPLS-connectivity services are based on powerful routers operated by NIIFI that support both IPv4 and IPv6, unicast and multicast. These routers are belong to Cisco ASR9000 series, Cisco Nexus7700, and Cisco Catalyst 6500 series .
