LONG: Laboratories Over Next Generation Networks. LONG IPv6 Backbone l The backbone is built on the interconnection links between LONG partners. l The BGP4+ routing protocol is deployed on LONG IPv6 backbone. l As the interconnection support is on IPv4, the connections are established through IPv6 over IPv4 tunnels, except on the UPM-TID link (IPv6 over ATM). l The PTIN-TID connection is only used when PTIN- UPM is down.

LONG: Laboratories Over Next Generation Networks. LONG IPv6 backbone: support l The interconnection between project partners is implemented using the infrastructure of the National Research Networks (NRN) of each country and the pan-European research network (GEANT): n Spain’s NRN: REDIRIS n Portugal’s NRN: FCCN l The connection from PTIN (Aveiro) to FCCN (GEANT PoP, located in Lisbon) is implemented using an ATM commercial link: n This connection is established when higher bandwidth is needed n When not established, the PTIN traffic is sent through Internet to TID n The PTIN-TID Internet connection behaves as a backup connection

LONG: Laboratories Over Next Generation Networks. CATV l There are no native IPv6 implementations over CATV infrastructure known by the project. l The model for deploying data services over CATV is based on the DOCSIS standard (layer 2) and IPv6 support isn’t include yet. l At this moment, the only existing solution is based on tunnel over IPv4.

LONG: Laboratories Over Next Generation Networks. DNS l BIND9 ( Berkeley Internet Name Domain, version 9) is used, which supports native IPv6 queries. l DNS server supports both A and AAAA queries (names to IPv4 and IPv6 addresses). Also, both IPv4 and IPv6 queries are accepted, since the DNS is installed on a dual stack machine and the client & server support IPv6. l To guarantee that the DNS system works continuously and looking for a realistic situation, TID has deployed the primary DNS server and secondary servers are being configured by other partners, such as UPM.

LONG: Laboratories Over Next Generation Networks. BGP4+ Most of the available IPv6 routers support BGP4+. In the project are used Cisco, Telebit, Zebra (Linux). Used Telebit software version, does not support ‘capabilities negotiation’ to achieve Cisco-Telebit interoperability this feature is disable in Cisco. PTIN’s router has a bug: if the AS number is bigger than 32k, it does not work: change AS number from 65451 to 25451.

LONG: Laboratories Over Next Generation Networks. Mobility & Multicast There are several implementations but only a few are included in commercial routers as stable implementations. IP Mobility adoption in real scenarios is growing BUT all transition mechanisms assume devices are static inside some IPv4 or IPv6 network. No current commercial router implements the IPv6 multicast routing protocols yet. KAME’s stack allows IPv6 multicast routing (PIM, both SM and DM). IPv6 multicast routers will be PC equipped with the operating system FreeBSD. Multicast Server Multicast Client A Multicast Client B IPv6 State: LONG IPv6 Backbone HA CN MN IPv6 State:
