NetX Duo for RZ
 NetX Duo is an extension of NetX that supports BOTH
IPv4 and IPv6 in the same dual-stack.
 NetX Duo adds the following protocols to NetX:
 RFC2460: Internet Protocol, Version 6 (IPv6) Specification
 RFC2461: Neighbor Discovery for IP Version 6
 RFC2462: IPv6 Stateless Address Autoconfiguration
 RFC2464: Transmission of IPv6 Packets over Ethernet Networks
 RFC4291: Internet Protocol Version 6 (IPv6) Addressing
Architecture
 RFC4443: Internet Control Message Protocol (ICMPv6) for the
Internet Protocol Version 6 (IPv6) Specification.
Specification
 IPsec

IPv6
 IPv4 uses a 32-bit
address, allowing
approximately 4.3

billion
addresses
dd
 IPv6 uses a 128bit address,
address allowing
2128, or
approximately 3.4×1038
addresses.

IPsec
 A protocol suite for securing Internet Protocol (IP)
communications by authenticating and encrypting each IP
packet of a communication session.
 IPsec is an end-to-end security scheme operating in
the Internet Layer of the Internet Protocol Suite
 Other Internet security systems in widespread use, such as
T

S
it (TLS) and

Sh ll (SSH),
(SSH) operate
t
in the upper layers of the TCP/IP model.
 IPsec protects any application traffic across an IP network.
 Applications do not need to be specifically designed to use
IPsec.

NetX Duo IPsec
 NetX Duo IPsec is an optional feature available to NetX Duo.
 NetX duo IPsec implements both encryption and
authentication:
 The encryption algorithms implemented by NetX Duo IPsec are
3DES and AES.
 The authentication algorithms implemented by NetX Duo are
MD5 and SHA1.
 The user may supply his/her own security algorithms and easily
integrate into NetX Duo IPsec.
 To establish an IPsec session, user may use IKEv2 (available
as part of the IPsec package) to automatically negotiate the
session parameters with its peer.

NetX Duo Validation
 The IPv6 layer is validated using the “IPv6 Core Protocol
(Phase 2) Self Test” package available from the IPv6
Ready Organization.
 The conformance tests used for NetX Duo are Test
Specification version 3.8.10 and Self Test Platform version
1.4.9.

Iperf
 From: http://en.wikipedia.org/wiki/Iperf
 Iperf is a commonly used network testing tool that can
create TCP and UDP data streams and measure the throughput
of a network that is carrying them.
 Iperf is a tool for network performance measurement written
in C. Iperf was developed by the Distributed Applications
Support Team (DAST) at the National Laboratory for Applied
Network Research (NLANR).
open-source
source software and runs on various platforms
 Iperf is open
including Linux, Unix and Windows.
 Jperf is a graphical user interface for Iperf

Running Jperf
 Double-click on the
Windows batch file
jperf bat This
jperf.bat.
launches the Jperf
IDE, as shown here.
 Once the Jperf IDE
is displayed, the
Server Address field
must be set to the
IP address of the
Demonstration
target
g board.
 In this example, the
target board IP
address is
192.2.2.47.

Running The Tests
 Browse to
the target
board via a
browser on
the Jperf
host
platform.

UDP Transmit
 The UDP Transmit
Test determines
the performance
of NetX UDP
transmission to
the host. In this
test, the
h NetX
N X
target is the
client and the
Jperf host is the
server.
 Select Server
and UDP in the
Jperf IDE.
 Next, select Run
IPerf! to initiate
the Iperf server.

Start UDP Transmit Test
 Now, from the
NetX Iperf
Demonstation
web page,
select the
Start UDP
Transmit
Test button to
initiate the
test.

UDP Transmit
 We now
observe
performance
statistics in the
Jperf IDE, and
the web page
is updated with
the results.
