19 Work done Study Study and evaluation of the transition mechanisms and their applicability to a set of scenarios; functional testing of available implementations. The deployment of IPv6 over different access and transport technologies were studied. The theoretical and functional aspects of applications and network services were studied with focus on mixed IPv4/IPv6 scenarios. Identification of available implementations and State-of-the-art Implementations were identified for the main OS and network equipment. Execution of practical experiments Some implementations were selected to be experimented and all the installation, configuration, operation and testing phases were documented, with a focus on the functional aspects. Deployment LONG s network Network platform to test services and applications in almost real-scenario.

20 Main Results (I) Network Backbone Each LONG partner has deployed mixed IPv4/v6 local networks. All these networks are linked building a single LONG IPv6 backbone, which has allowed to test services and applications in almost real-scenarios. Usage of different technologies to connect these partner s networks: IPv6 over IPv4 configured tunnels (PTIN-UPM, UEV-UPC, UPC-NOR); IPv6 over ATM link (PTIN-UPM, TID-UPM, UC3M-UPC); IPv6 over GbEth/DWDM (UPM- UC3M); 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.

21 Main Results (II) Deployment of access technologies Access technologies: ADSL (TID) CATV (PTIN) WLAN (UPM) ISDN (UEV). 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.

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

23 Main Results (IV) Routing Protocols Partners: Static routes / RIPng. Backbone: BGP4+ is used. Each partner was assigned a private AS Initial phase? PTIN is connected to TID through Internet but this connection was only used when PTIN-UPM link is down. This is performed automatically using the BGP features. Due to the cost of communications to connected to POP GEANT, the PTIN-UPM is only established when the bandwidth is demanded TID MAD6IX Euro6IX LIS6IX PTIN Public UPM Rediris GEANT FCCN UEV UC3M UPC? Final phase (Dez/02 - ) TID Internet PTIN UPM Rediris GEANT FCCN Public UEV UC3M UPC PTIN is connected to UPM through Euro6IX network This connection has enough bandwidth for the requirements of LONG services. As the routing on Euro6IX is not define yet, static routes are used in PTIN-UPM (UPM advertises PTIN prefix)

24 Main Results (V) Deployment Advanced Network Services Mobility Multicast Anycast Security Multihomming QoS Identification and evaluation of available implementations. Study of functional aspects related with the deployment in mixed IPv4/IPv6 scenarios. Analyze of the impact on network design, based on requirements and available communication resources.

61 Real User Trials Service Deployment Guidelines on IPv4/IPv6 Environments

62 Service Deployment Guidelines on IPv4/IPv6 Environments Service Deployment Guidelines on IPv4/IPv6 Environments Key idea: try to hide complexity to the users (as much as possible) Comments Tunnels are easy to manage tools for IPv6 to IPv6 communication over IPv4 islands Preferred: configured tunnels and 6to4 To allow seamless access to a service from IPv4 and IPv6 clients Preferred: use servers coded for allowing both v4 and v6, and place it on a dual stack machine E.g. Isabel, IRC, web, most services Use single stack servers connected through a translation mechanism Clients connect to the server with the same protocol E.g. IRC, LDAP deployment at LONG network Place translators between servers and clients just if it cannot be avoided

63 Experiments Advanced Applications Performance Testing Advanced Transport/ Access Access Technologies IPv6 Transition Mechanisms and and Advanced Network Services Advanced Functional Testing

64 Performance Testing Performance Testing Evaluate the IPv6 network infrastructure and services for supporting real user events Evaluate basic application performance (DNS, Web) for high-load events such as Campus Party ISABEL requirements are kept on mind when defining testing scenarios Provides traffic characteristics Provides parameters to measure: packet loss delay, variation of delay MGEN6 and Netperf used Test behavior of Transport/access technologies (CATV, ADSL, ATM, ISDN, b, Ethernet) Transition mechanisms (tunnels and translators) Stable links on the LONG network Results should be valuable for people asking: Will I loose performance when switching to IPv6 or Will I loose performance at the transition stage Tested simple configuration (the number of cases grows exponentially when complex scenarios are included) Guidelines presented at D4.1 Results from first phase at D4.2 Additional tests proposed at D4.3, executed at D4.4

65 Performance Testing Conclusions Performance Testing Packet size is a much relevant communication parameter in terms of performance for environments including Ethernet segments Several tests made to characterize this parameter on the set of tests to perform Link performance testing provided detection of otherwise silent problems (misconfiguration, software problems, etc.) In general, the use IPv6 does not lead to performance penalty on the equipment tested Tunnel transition mechanisms do not also show performance inconveniences NAT-PT is a valid transition mechanism for ISABEL-like applications with the available equipment It requires manual configuration Regarding to the test of access technologies In the CATV equipment tested the upstream traffic was limited (1 Mbps) For using ISABEL over both ADSL and CATV the asymmetry of the channel should be taken into account No native IPv6 support was available at the time of testing for the considered equipment. Commercial equipment was not mature.

66 Advanced Functional Testing Advanced Functional Testing Advanced Network Services Multicast Diffserv Mobility Anycast Multihoming Basic tests, since Most advanced network services were not stable at the time of testing (Not mature implementations available, changes at the specification of the protocols) Limited experience on the deployment of this services on IPv6 Application Service Deployment IRC, News, LDAP, etc. Key test driver: consider service deployment in networks performing transition Guidelines presented at D4.3 Results presented at D4.4

72 Anycast ciempies (secondary DNS) fec0:1::ffff cucaracha Termita tarantula UC3M Network Pulgon mira (primary DNS) zangano (secondary DNS) fec0:1::ffff Simple anycast experiment performed Current solutions prevent from host anycast communication Fundamental state problem if TCP is used, Not so important problem for UDP (for this, restriction could be removed), although not very much useful services apart from DNS Basic routing can be performed by route injection of specific routes with some restrictions It has to be addressed host availability propagation

73 Multihoming BGP multihoming definitely works It keeps TCP connections alive in the scenario tested However, still to define rules to control BGP route injection Other options not requiring injection of routes Tunnels to provide fault tolerance for specific providers ( Multihoming Support at Exit Routers ) Limited protection, should preserve connections Address Selection mechanisms When properly configured, selection of addresses results in selection of paths, circumventing failures Other mechanisms involving hosts and routers Extension Header for Site-Multi-homing Support. October 2002.

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

75 Conclusions Several scenarios in which most relevant standard network applications working seamlessly for IPv6 clients, and also for IPv4 clients DNS, Web, FTP, News, LDAP, Mail, IRC, ISABEL If translation is required, 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 Next step: adapting less standard applications, and ease transition Equipment support Required better support for several link layers (ADSL, CATV) Gigabit routers beginning to perform IPv6 forwarding by hardware Advanced features Mobility in general offers better support for IPv6 than for IPv4 Diffserv and multicast working similarly to IPv4 Although much work required for mixed IPv4/IPv6 environments Multihoming and anycast are still not properly solved Some contributions have been made to multihoming (see WP5)
