Euro6IX: The Concept• How to pronounce it: forget IX and read 6 (“SIX”)
• Build a large, scalable and native IPv6 Backbone of Traffic Exchanges, with connectivity across Europe and other IPv4/v6 Exchangers
• In order to promote and allow other players to trial v6 and port/develop key applications and services
• In order to break the chicken and egg issue !• Gain REAL IPv6 experience, in a real world with not just
research users, involving Telcos/ISPs/ASPs, among others: Allow new players into our trials
• Bring IPv6 into a production transit service
- 3
Euro6IX Goal• Support the fast introduction of IPv6 in Europe.• Main Steps:
– Network design & deployment– Research on network advanced services– Development of applications validated by user
groups & international trials– Active dissemination:
• participation in events/conferences/papers• contributions to standards• project web site
- 4
Objectives1. Research an appropriate architecture, to design
and deploy the first Pan-European non-commercial IPv6 Internet Exchange Network.
2. Use this infrastructure to research, test and validate IPv6-based applications & services.
3. Open the network to specific User Groups for its validation in trials.
4. Dissemination, liaison and coordination with clusters, fora, standards organizations (e.g. IETF, RIPE) and third parties.

Layer 3 IX• Infrastructure providing both layer 2 and
layer 3 interconnection service.• Several IXs can make direct peering offering
also Wide Area Layer 3 transport as an Internet Service Provider. Every IXs will use an assigned xTLA prefix (x=p or s) to assign NLA prefixes to ISPs or customers connecting to the IX.
• Project partners will use their xTLA prefix to assign NAL to customers and regional ISP connecting to IX.

RFC2374 Benefits• This model is based on the RFC 2374 to verify that:
– a customer could change its service provider without changing its addressing space
– the renumbering functionality could be realized more easily (no renumbering in the better case)
– the multihoming functionality could be realized more easily• IX plays an intermediation role between the ISP and the
customers (Layer 3 mediation function router)• Routing:
– iBGP+IGP: inside the Long Haul Provider – Euro6IX is the collection of the routers inside the IX emulating the
LHP (single AS)– eBGP4+: between the customers and the IX– eBGP4+: between the IX and the LHPs

IX Based Services• IX becomes a place where new services are offered to the
users.• IX is an aggregation point, so it can provide those services
who can benefit by this “user aggregation” (e.g. in a based multicast network, the RP could be located inside the IX, because a lot of users connect to it).– Network Services
• Multicast, AAA, QoS, DNSSec• Transition Mechanisms: NAT-PT, Tunnel Broker, 6to4• Route Server mechanism
– Application Services• HTTP, FTP, SMTP• VideoConference/e-learning services• P2P applications
– Monitoring Services• Routing/Traffic/Reachability Monitoring (Magalia, AS-Path tree, Looking Glass)

(RFC3363)• Servers and resolvers with IPv6 MUST
support EDNS0 (RFC3226)• Good support in DNS servers• Some TLDs with IPv6 and AAAA

DNSv6 (III)
• What does these all means?• AAAA as easy as A records• Reverse lookups are little bit more difficult to
manage• Be aware of the lack of IPv6 transport up to
the root servers -> need of IPv4 connectivity
- 25
DNSsecv6 (I)• Provide integrity and authentication to security aware
DNS entities: for both queries and zone transfers• Defined independently of the IP version used• DNS resolvers and servers with DNSsec MUST
support EDNS0 (RFC3226)• Storage of authenticated public keys in the DNS
(support for general public key distribution services as well as DNS security)
• Use cryptographic digital signatures which are included in secured zones as RRs
• TSIG (Transaction signatures) to secure DNS messages. Private shared keys. Simple and lightweight. (RFC 2845)
- 26
DNSsecv6 (II)• Each node in the DNS tree is associated with a public
key.
• Each key is authenticated by the parent zone, up to the root (globally secure)
• Or up to a security security root (locally secure)
• Handling of DNSsec keys
• The querier will receive signatures of RRs and the public key, for signatures the private key associated with the public key of the domain is used
• A DNSsec aware resolver will follow the “chain of trust” of public keys, until it reaches a trusted one.

Euro6IX Work (III)• DNSsec emulator tool• OBJECTIVE: creation of complex DNS
scenarios made of complete name server hierarchies inside one computer, in order to test different scenarios and configuration alternatives before deploying the service to real servers.
- 33
Euro6IX Work (IV)• Certificates management with DNSsec• Study the use of a secure DNS service to
publish digital certificates in cooperation with a PKI
• The CERT RR can be used to store certificates in the DNS. The types of certificates currently defined are X.509, SPKI and PGP certificates. It is intended that personal public keys should be stored in the DNS using the CERT record, and not by using the KEY record.
- 34
Open Issues• DNSv6
– Autoconfiguration: DHCPv6, RA, others?
– Reverse lookups: IP6.INT -> IP6.ARPA
– Root servers with IPv6
• DNSsec– Key management
– root servers with DNSsec
- 35
Multicast Advantages• Network bandwidth optimization (e.g. multicast
network makes a copy of the packets only when needed)
• Source optimization (e.g. no need to transmit a packet per destination)
• Well scalable technology (e.g. when a receiver is added to a network, no addiction cost is required)
- 36
Operating Multicast: M6Bone• Core routers running typically PIM-Sparse
Mode• Access routers running PIM-SM and
additionally MLD (for group managing)• Hosts implementing the MLD protocol • Users are grouped in the so-called “multicast
groups”. All the hosts inside a multicast group, have the same multicast address and when a host wants to add or to leave a group, it has only to communicate this to the border router of the network where it is connected to.
- 37
The M6Bone
- 38
Implementing QoS• In a typical model for QoS implementation over an administrative
domain, the network is composed by a core and edge (usuallyPoPs) routers. Following the DiffServ model in its simplest way, the traffic coming from the customers is received by the edge routers, marked on DSCP, and policed or shaped according to the SLAs.
• In this simple model, with a single Service Provider all the tasks are performed within the same administrative domain, and it can be insured that the marking, policing and queuing tasks applied to the packets along the network are coherent.
ISP
- 39
Implementing QoS in Real Life• The real world, like in Euro6IX, is not a single Service Provider, but
a lot of them.
• To implement a global QoS we need to define agreements of SLSsbetween the partners (different administrative domains).– In some cases the remarking could be needed.
– The definition of SLAs is needed in order to define how much traffic is allowed between the providers.
• In the case which some external entities are used by the Providers, to manage the QoS provisioning, interoperability is already needed between these entities in order to negotiate the SLAs dynamically.
ISP1 ISP3ISP2
- 40
Euro6IX model of QoS• The Euro6IX models also brings the new L3 IX.
• This situation doesn't changes anything the model. The IX network should be considered as one Service Provider more.
• The only new requirement from the 6IX is the provisioning of L2 QoS, using 801.2P technology.
• This is needed to support in a coherent way the L3QoS. But not just the Ethernet-based should do it. All the other connections either ATM or FR should do the same, if possible.
- 41
AAAv6• Radius for IPv6 is standardized, but not well
implemented (RFC3162)
• Almost no implementations using UDP/IPv6
• Some IDs for DIAMETER usage with IPv6– Some preliminary implementations
• http://playground.sun.com/diameter
• http://sourceforge.net/projects/diameter
- 42
Network Access• Well supported and implemented:
– PPPoA (RFC2364)
– PPPoE (RFC2516)
– IPv6 over PPP (RFC2472)
• The question is how the remote host obtains the global IPv6 address instead of the link-local one. Usually:– Router Advertisement
– DHCPv6 (RFC3315)
- 43
Mobility• Mobile IPv6 (proposed standard draft-ietf-mobileip-
ipv6-24.txt last July) describes basic functionality and agents that take part on it
• Other documents in progress, including:– Security in signaling for MIPv6 (http://www.ietf.org/internet-
drafts/draft-ietf-mobileip-mipv6-ha-ipsec-06.txt)– Handovers enhancements (HMIPv6,
http://www.ietf.org/internet-drafts/draft-ietf-mobileip-hmipv6-08.txt and FMIPv6 http://www.ietf.org/internet-drafts/draft-ietf-mobileip-fast-mipv6-06.txt)

Measurement Device and Server• The measurement device inserts precise
timestamp information when it captures the IPv6 packet.
• Each device has time synchronization functionality, by GPS, or any other equivalent mechanism.
• The measurement server collects the captured IPv6 packet.
• Then it provides usage and also QoS metrics (delay, loss, jitter and so on).

QoS & Management• The operators and ISPs must be capable to control the
QoS, to measure it objectively and to share information with the clients according the SLAs contracts.
• These measures are useful also to compare ISPs (comparison of SLAs provided by different ISPs).
• Is necessary to carry out measurement on both, network and application level.
• The correlation processing in the application level needs elaborating very complex rules, so 6QM project focus is only on the network level itself.
- 52
6QM Expected Achievements• Operational rules and practical tools.• Small test-beds and measurement systems,
towards their use in large-scale networks. • Build formal models based on empiric
measures achieved on operational IPv6 networks (e.g., Euro6IX, 6NET)
• Implicate other network communities to build a significant and representative scenario.
