n
n
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

Conclusions
l
Network and Basic Services
n
IPv6 covers all basic IPv4 aspects, even improving most of them
The is available equipment that allowed the project to built a stable IPv4/v6
test platform providing the basic services (routing, DNS)
n
l
Network Advanced Services
n
l
User Services/Applications
n
l
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
Most of the applications have been adapted/ported for IPv6
IPv4/v6 Transition
n
Actual Transition Mechanisms do not fully support all the advance network
services:
Connectivity and application operation is well supported
Advanced network aspects, like QoS, Mobility, Multicast and Security are not
fully supported or are impossible to be deployed.

WP4 Objectives
“System Exploitation, Trials and Evaluation will perform
trials and experiments over the platform deployed making use of
the adapted applications. These trials will help to fine tune the
design and to elaborate recommendations. These
recommendations will be produced in the corresponding Work
Packages taking as input the trials and experiments performed.
LONG will produce recommendations related to: IPv4/IPv6
transition, IPv6 and advanced services integration, the
interworking of heterogeneous access scenarios and the
adaptation of applications to the Next Generation networks.“

Service Deployment Guidelines
on IPv4/IPv6 Environments
l
l
Key idea: try to hide complexity to the users (as much as possible)
Comments
n
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
n
n
n
– E.g. Isabel, IRC, web, … most services
n
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
n
Place translators between servers and clients just if it cannot be avoided

Performance Testing
Evaluate the IPv6 network infrastructure and services for supporting real user events
n
n
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, 802.11b, 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”
n
n
n
n
n
n
l
– Tested simple configuration (the number of cases grows exponentially
when complex scenarios are included)
Guidelines presented at D4.1
n
n
Results from first phase at D4.2
Additional tests proposed at D4.3, executed at D4.4
Performance Testing Conclusions
l
Packet size is a much relevant communication parameter in terms of performance for
environments including Ethernet segments
n
l
l
l
l
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
n
l
Performance Testing
It requires manual configuration
Regarding to the test of access technologies
n
n
n
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.
l
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
n
n
n
n
n
n
n
n
l
Application Service Deployment
IRC, News, LDAP, etc.
Key test driver: consider service deployment in networks performing transition

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
n
It has to be addressed host availability propagation
Multihoming
l
BGP multihoming definitely works
n
n
l
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
n
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

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
Conclusions
l
Several scenarios in which most relevant standard network applications working
seamlessly for IPv6 clients, and also for IPv4 clients
n
DNS, Web, FTP, News, LDAP, Mail, IRC, … ISABEL
If translation is required,
n
– Sometimes this implies special configuration (for example, detailed
configuration of NAT-PT address maps)
– Known problem for applications transporting addresses
n
n
l
Equipment support
n
n
l
Missing DHCPv6 (debate for its need), required better support for NFS
Next step: adapting less standard applications, and ease transition
Required better support for several link layers (ADSL, CATV)
Gigabit routers beginning to perform IPv6 forwarding by hardware
Advanced features
n
n
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)

Quake through NAT-PT:
(1) An IPv6-client starts the connection.
(2) NAT-PT translates the packets to IPv4 automatically: map from any6 to 163.117.140.200
(3) Other IPv4-clients connect to the same server.
Although Quake2 exists for IPv6, bots only run with the IPv4 version (because there is not
source code available).

IRC service for IPv6/IPv4 users:
TRT: Allows the IPv6-IRC server to talk with an IPv4-IRC server.
(1) One client establishes an IPv4 connection.
(2) Another client establishes an IPv6 connection.
The IRC network works transparently for IPv4 and IPv6 users, as long as the servers keep
connectivity between both realms.
