The deployment of IPv6 over different access and transport technologies were studied. I The theoretical and functional aspects of applications and network services were studied I with focus on mixed IPv4/IPv6 scenarios. Identification of available implementations and State-of-the-art G Implementations were identified for the main OS and network equipment. I Execution of practical experiments G Some implementations were selected to be experimented and all the installation, I configuration, operation and testing phases were documented, with a focus on the functional aspects. Deployment LONG’s network G Network platform to test services and applications in almost real-scenario. I LONG: Laboratories Over Next Generation Networks.

Main Results (I) Network Backbone G I Each LONG partner has deployed mixed IPv4/v6 local networks. I All these networks are linked building a single LONG IPv6 backbone, which has allowed to test services and applications in almost real-scenarios. I Usage of different technologies to connect these partner’s networks: IPv6 over IPv4 configured tunnels (PTIN-UPM, UEV-UPC, UPC-NOR); I IPv6 over ATM link (PTIN-UPM, TID-UPM, UC3M-UPC); I IPv6 over GbEth/DWDM (UPM- UC3M); I I BGP4+ is used as the main routing protocol in the backbone. Acquisition of knowledge through practical experiments and documentation � of the results. Evaluation of the IPv6 deployment state over different technologies with � equipments of various manufactures. LONG: Laboratories Over Next Generation Networks.

Main Results (II) Deployment of access technologies G I Access technologies: I ADSL (TID) I CATV (PTIN) I WLAN (UPM) I ISDN (UEV). I Ethernet (All) There is equipment available that implement native IPv6 over these � technologies, except for CATV; in this case, the only existing solution is based on tunneling of IPv6 over IPv4 � The model for deploying data services over CATV is based on the DOCSIS standard (layer 2) and IPv6 support is not included yet. LONG: Laboratories Over Next Generation Networks.

Main Results (III) Deployment of Basic Network Services: DNS & Routing G DNS: � Based in BIND9 ( Berkeley Internet Name Domain, version 9) on Linux, which supports I native IPv6 and IPv4 queries.

Conclusions Network and Basic Services G I IPv6 covers all basic IPv4 aspects, even improving most of them I The is available equipment that allowed the project to built a stable IPv4/v6 test platform providing the basic services (routing, DNS) Network Advanced Services G I Some of the implementations still lack reliability, since are still in a mature state Ex.: there are few multicast implementations and some aspects of mobility are being discuss User Services/Applications G I Most of the applications have been adapted/ported for IPv6 IPv4/v6 Transition G I Actual Transition Mechanisms do not fully support all the advance network services: I Connectivity and application operation is well supported I Advanced network aspects, like QoS, Mobility, Multicast and Security are not fully supported or are impossible to be deployed.

Multihoming BGP multihoming definitely works G I It keeps TCP connections alive in the scenario tested I However, still to define rules to control BGP route injection Other options not requiring injection of routes G I Tunnels to provide fault tolerance for specific providers (“Multihoming Support at Exit Routers”) I Limited protection, should preserve connections I Address Selection mechanisms I When properly configured, selection of addresses results in selection of paths, circumventing failures I Other mechanisms involving hosts and routers I “Extension Header for Site-Multi-homing Support”. http://www.rfc- editor.org/internet-drafts/draft-bagnulo-multi6-mhexthdr-00.txt.

Experiences with Application Services Most of the experience scenarios were included into the stable infrastructure G Seek for easiest (regarding to user deployment) strategy in mixed IPv4/IPv6 G networks I ISABEL and transition mechanisms (6to4, NAT-PT) I DNS and Web server performance, I DNS, Web, FTP, News, LDAP, Mail through NAT-PT I IRC through TRT I NFS over IPv6, and IPv4 NFS clients accessing IPv6 servers (FreeBSD) I Also tested ISATAP and DSTM deployment LONG: Laboratories Over Next Generation Networks.

Conclusions Several scenarios in which most relevant standard network applications working G seamlessly for IPv6 clients, and also for IPv4 clients DNS, Web, FTP, News, LDAP, Mail, IRC, … ISABEL I If translation is required, I – Sometimes this implies special configuration (for example, detailed configuration of NAT-PT address maps) – Known problem for applications transporting addresses Missing DHCPv6 (debate for its need), required better support for NFS I Next step: adapting less standard applications, and ease transition I Equipment support G Required better support for several link layers (ADSL, CATV) I Gigabit routers beginning to perform IPv6 forwarding by hardware I Advanced features G Mobility in general offers better support for IPv6 than for IPv4 I Diffserv and multicast working similarly to IPv4 I Although much work required for mixed IPv4/IPv6 environments I Multihoming and anycast are still not properly solved I Some contributions have been made to multihoming (see WP5) I LONG: Laboratories Over Next Generation Networks.
