NuDOG-101 is a handheld device with two 10/100Mbps ports for Ethernet testing. The main functions of NuDOG-101 include multi-streams generation, TAP/Loopback test, and NIC emulation.

Connecting NuDOG-101 to its mini-USB port makes it possible for system configurations and managements. NuDOG-101 is an ideal device for in-field testing. Also, various test port interfaces (such as UTP ports, POF ports, and Combo ports (RJ45+POF)) are available as well.

NuDOG-101 can work along with a series of utility softwares that qualify industrial standards such as RFC-2889, RFC-2544, and QoS. With these utilities, NuDOG-101 is able to conduct throughput test, latency test, error filtering test, forwarding test, and so on. Utility softwares can provide a user-friendly interface for different test configurations when setting test parameters and criteria. More optional softwares are available for extended test requirements.

With these advantageous features, NuDOG-101 is your best partner for LAB researching and in-field troubleshooting.

● Real-time statistics for each port, including transmitted/received frame for VLAN, IPv4, IPv4 fragment, IPv4 extension , ICMP, ARP, total bytes/packets, CRC, IPCS error and over-and-under size frames.

● Bi-directional Symmetric and Asymmetric wirespeed test.

● User-friendly interface that supports various parameter configurations and meets various test requirements.

● High performance without high price

● Provides Streams Generation Mode, TAP/Loopback Mode and NIC mode for different requirements of test.

● Streams Generation Mode: 
For Streams Generation mode, this device generates bi-directional network streams for required test as the illustration above. Both Port A and Port B of this device can generate and receive test streams. The test streams are sent and return to original NuDOG-101 for analysis of the DUT (device under test).

● TAP/Loopback Mode:
For TAP mode, this device can monitor any data that flows through this equipment. Network TAP is a method for monitoring dynamic situation of network without intruding it. This device can tap bi-directional or uni-directional traffic from different sides (port A and port B) and also provides abundant packet counters. For Loopback mode, this device resends the incoming streams back to the source.

● NIC Mode:
This mode is to simulate network interface card.
