The DN-900H Network Performance Tester is easy to use and can be tested with a pre-defined and ready-to-change performance test suite that can be modified at the touch of a button.

 

RFC2544 Performance Benchmark

 

The DN-900H Network Performance Tester is a powerful Ethernet performance test tool that uses the standardized point-to-point test method defined by RFC2544 to measure throughput, latency, back-to-back frames, and frame loss. Test results can be stored on a USB flash drive. on.

 

Network detection and error location

 

The DN-900H Network Performance Tester can quickly and easily determine 10/100/1000 Mbps Ethernet network conditions, including network utilization, broadcast, collision and error, and can check for incorrectly assigned subnet masks and misconfigured servers. And duplicate IP addresses.

 

Configurable line rate of 1 Mbit/s-1 Gbit/s

 

The DN-900H Network Performance Tester supports IEEE 802.3 standard 10/100/1000BASE-T copper cable and 1000BASE-SX/LX/ZX Gigabit Ethernet SFP optical interface. Provides a maximum line speed of 1000Mbps on copper and fiber interfaces. You can configure any line rate up to 1000Mbps to make testing faster and more efficient, and you only need to test the rate of information that you (or your customers) are interested in.

 

VLAN test

 

Eight unicast exact match address filters are provided for filtering DA or SA based frames with optional VIDs. At the same time, the VLAN performance test tool generates network traffic that can be configured for different applications to test VLAN performance.

 

Bit error rate test

 

The bit error rate test tool performs various network/service routine maintenance and testing and test functions necessary for Ethernet service provisioning through various stress test patterns specially designed for various network technologies in the metro transmission network.

 

Complete statistical function

 

Supports the MAC address, IP address, NetBIOS name, NetBIOS domain, DNS name, SNMP name, server, line utilization, broadcast and multicast number, packet error rate, collision rate, FCS error frame of the connected network and node. Statistics of number, frame length, number of long frames, number of ultra-short frames, etc.; support statistics on the distribution of network layer protocols. Network conditions can be analyzed based on statistical results.

 

 Perfect IP bearer network test method

 

Supports a variety of testing methods such as network element equipment, network end-to-end performance and distributed end-to-end network performance testing, which can be measured by point-to-point dual-ended instruments or two instruments, multi-point to multi-point The instrument test and other methods complete the overall maintenance of the IP bearer network.

 

 Complete application layer testing

Small size, light weight, and rechargeable battery, user operation is simple and efficient, suitable for on-site business operation environment.

 

DN-900H network performance tester is mainly used for performance test and protocol analysis of Gigabit Ethernet. The instrument adopts modular design, test host and test module are independent, easy to upgrade test, and provide multiple instruments to test at the same time. Inter-instrument clock synchronization method. The meter supports multiple monitoring modes, which can capture 100% data in any case without losing packets. The meter provides long-term network monitoring and preserves raw data, statistical results, and test results.

• Input signal rate: 10/100/1000 Mbit/s adaptive

  With full line rate traffic capability, it can generate and transmit 10/100/1000Mbps Ethernet traffic at full line rate.

  Users can generate a variety of Ethernet frames, including constant, bursty, ramp frames, and more.

  The length of the Ethernet frame that can be tested is: from the minimum frame length to the MTU order increment. It includes 64, 128, 256, 512, 768, 1024, 1280, 1518 byte frames and typical applications such as "JUMBO" (large frame, up to 64K bytes).

  It can test the performance impact of a router receiving a data frame in a random 256 network addresses.
