1. NuTEA-551 Overview

1.1. NuTEA-551 General Description

NuTEA-551 is a network impairment device that impairs
Ethernet network to emulate unstable network conditions,
especially networks with complex topology, such as Internet
in public network.

It is a compact, lightweight, and highly cost-effective device
that provides the function to simulate Ethernet traffic
impairment situation, such as CRC Error Packet, Packet
Corruption, Packet Drop, Packet Order Exchanging
(Re-order), Packet Duplicate, Delay, Jitter, and Limiting
Packet Transferring Rate. Variables regarding to these impairments can be set with accurate
high-precision and apply for all kinds of Devices under Test (DUTs).

With functions mentioned above, NuTEA-551 is capable of emulating almost any possible error that could
happen in real-world network environments. While developing network products, it is crucial to
understand how these under developing products would perform or react when network errors occur.
NuTEA-551’s impairment emulating capabilities allow manufacturers to perform tests with their products
in labs. Also, NuTEA-551 can emulate packet delay and packet jitter as well, and the packet delay/jitter
time can be set in milliseconds (ms) or microseconds (μs).

NuTEA-551 provides a controllable blemish network environment for manufacturers to test their products’
performances within lab network environments. With NuTEA-551’s capability to set and change network
impairment settings dynamically, it is easy for users to build a customized network environment for
product demo or testing product’s specific function.

Embedded with Voltage-Controlled Crystal Oscillator (VCXO), NuTEA-551 can be adjusted to match/jitter
its PHY chip’s frequency within the range of ±100 ppm via utility software.

Also, NuTEA-551 supports Maximum Impairment Limit, which allows users to set the number of times for
error emulations with NuTEA-551’s utility software.

Protocol

• Utility software with setting options that allows users to set:

¾ SDFR (Self-Discover Filtering Rules), a set of filtering rules including Destination Address,

Source Address, VLAN, Destination IP, Source IP, Destination Port, and Source Port

¾ 2 sets of Session Filter including Port A → Port B and Port B → Port A

• Embedded with Two RJ-45 & Fiber Combo Ports

• Supports RMON Counters

1.3. Main Applications of NuTEA-551

• DUT Performance Testing and Analyzing

¾ Conducting DUT Performance Tests in Emulated Network Environment
¾ Various Embedded Packet Counters of NuTEA-551 for Checking DUT Counters’ Reliability

• DUT Troubleshooting. With network which emulates public network with poor bandwidth, users can

examine and see if the DUT has good network disaster recovery ability

• Validate and check if other test devices in mass production line are working properly or having the right

settings, and capable of picking up faulty DUTs

• Emulating and building a real-world network environment for demonstration purposes

• Products aiming for Telecommunication Service Provider can use NuTEA-551 for functions examining

and testing

1.4. Impairment Overview of NuTEA-551

NuTEA-551 can simulate different Ethernet traffic impairment situations, including:

CRC Error Packet

At the tail of a packet, it keeps a checksum value to verify the correctness of the packet when it is
received. If the checksum value is not correct that can verify the correctness of the packet, we call it CRC
Error Packet.

Packet Corruption

For some reason intentionally or unintentionally, the content of packet is modified, owing to poor
transmission or manual interference.

Drop Packet

Ethernet is a family of frame-based computer networking technologies. Frames are transmitted via
different devices and media. Af ter the transmission via dif ferent media and devices, some of frames might
be lost. For layer 2 switching mode of OSI model, packet is the same as frame.

Packet Re-Order

All of frame/packet should be transmitted sequentially, and it is able to reunite to complete data at
destination device. If the frame/packet sent goes different routes, it might be possible that later packet
arriving destination earlier, so the sequence of packet is changed, owing to poor device or manual
interference.

Packet Duplication

Packet is transmitted one by one via network device. For some reason, the destination had received the
packet, however the sending side does not received the acknowledgement, so packet is resent and
duplicated packet is generated.

Packet Delay & Jitter

Delays may occur during packet/frame transmission in real world network environments. Also, these time
periods of data transmission delays may vary, and are usually referred as jitters.

For more information regarding how to configure these Ethernet traffic impairment situations, please refer
to 5.4. NuTEA-551 Parameter Settings.

Impairment from Multiple Devices

If a single unit of this machine is not enough to generate the impairment environment required, you can
connect it in serial or in parallel to create any kinds of possible impairment structure.

In Serial

NuTEA-551 can be cascaded for multiple impairments.

In Parallel
NuTEA-551 can be connected in parallel to emulate impairment from different source network.
