XproUESimulator provides complete 5G NR UE side protocol stack simulation capabilities, including PHY, MAC, RLC, PDCP, RRC, NAS, SDAP protocol stack modules, supporting TDD/FDD mode, and has completed docking tests with over 20 brand base stations. XproUESimulator has achieved industry-leading protocol compatibility indicators, thanks to the flexible programming capability of software defined radio and the ability to complete functional integration testing with base stations within 3 days. Its compatibility adaptation speed exceeds that of similar products. XproUESimulator supports both cell level and UE level diagnostic logs in test result output, as well as real-time stream storage and offline graphical analysis of signaling streams, making it convenient for testers to diagnose. XproUESimulator also has the ability to capture real-time air interface data, which can capture the air interface data sent bidirectionally by UE and base station sides for storage and analysis. XproUESimulator provides unique programmable protocol stack capabilities, allowing customers to edit the NAS layer and RRC layer signaling encoding and decoding formats and signaling processes of the UE on site, for systematic testing of base station protocol stack robustness and protocol vulnerability mining. This is the industry's first tool product that can perform base station vulnerability testing, with a globally leading level of innovation.

A network impairment test instrument is a device that can simulate real wide area network conditions. It can simulate network states such as latency, jitter, bandwidth changes, packet loss, out of order, and packet duplication by processing data packets. A network impairment tester is widely used in various experimental scenarios in the data communication industry. Dotouch XproWanSim tester has been officially released. Unlike traditional hardware network impairment test instrument, the XproWanSim network impairment tester is completely software defined. Customers can choose any universal X86 server or host to deploy the network impairment test instrument, and still obtain high-precision network impairment simulation functions of up to 10Gbps or more. It is also possible to deploy the network impairment tester on a cloud platform to simulate network impairment within the cloud platform. XproWanSim supports the following key technical features: 1. Link latency simulation from 10 microseconds to 10 seconds. 2. Jitter simulation, with a jitter range from 1 millisecond to 10 seconds. 3. Packet loss rate control accuracy of 10 ^ -6. 4. Bandwidth control based on Kbps accuracy. 5. Support for out-of-order and repetitive sending of data packets. 6. Support flow matching according to 5-tuple rules and set impairment rules according to the flow. 7. Support flow matching for 5-tuple rules within GTP-U tunnels and set impairment rules based on the flow. 8. Support multiple flow matching rules to take effect simultaneously, with each flow using different impairment rules. XproWanSim deployment is very simple, using the DPDK architecture, it can adapt to a large number of mainstream server network cards, including Intel i350, 82599, X710, XL710, etc. Dotouch will provide a one click installation script, which only takes 30 minutes to complete the installation and deployment on the server. XproWanSim also allow users to easily click the mouse and complete the testing configuration within 10 minutes. Easy to learn, as long as you have basic network knowledge, you can master the configuration and usage methods.

There has been a surge in testing requirements in the field of industrial control. Due to the introduction of IT network technology, it is necessary to conduct functional, performance, and security tests on the network interface communication capabilities of PLC and DCS to ensure that the industrial control equipment connected to the network can meet operational standards. The introduction of 5G technology requires verification of the functionality, performance, and stability of industrial control systems that integrate 5G modules, to see if 5G technology can effectively replace traditional wired communication technology. In addition, the booming development of the industrial control security industry has brought about a large demand for testing the functionality, performance, and attack protection capabilities of industrial control security equipment itself. However, there is currently no mature industrial control testing product on the market that can help industrial control equipment R&D personnel conduct efficient and easy-to-use equipment testing. A large number of industrial control product tests are still conducted manually, using PC simulation tools and PCAP file comparison for verification. This basic testing method can not meet the requirements brought about by the current IT and CT technology of industrial control. In terms of testing accuracy, testing efficiency, and new technology adaptation, it is far from being able to adapt to the test requirements. Dotouch XproNetwork Simulator (XproNS) network simulation test can simulate mainstream industrial control protocols and industrial control PLC/DC devices on the standard X86 platform, and achieve functionality, performance, and security testing of industrial control equipment in a very simple and easy-to-use way. It can also test the functionality, performance, and security protection capabilities of industrial control security equipment. It perfectly solves the pain points of the current lack of testing tools and low testing efficiency in the industrial control industry. XproNS natively supports the following ICS protocols based on real ICS protocol stack: Modbus, OPCUA, Handle, LWM2M, CoAP, MQTT, IEC104, IEC61850_SMV, IEC61850_MMS, DNP3, Siemens S7, HART. And more ICS protocols will be added. Through L7 capture/replay function, XproNS can expand to support more ICS protocols based on two-arms testing scenarios. Now, our L7 capture/replay library has more than 50 ICS protocols.

Dotouch XproNetworkSimulator (XproNS) is a network simulation instrument designed specifically for simulating various applications traffic and attacks, with powerful DDoS attack simulation capabilities. It can support attack simulation using multiple 100GE ports on a single server, and can send attack traffic up to 100Gbps. While providing high-performance attacks simulation, it can also support very flexible DDoS attack type definitions. Testers can flexibly edit any DDoS attack signature through graphical means on the instrument GUI, including tunnel attack features, variable attack features, etc. Performance: XproNS can reach: - 41 million packets per second and 29Gbps throughput, based on 64 bytes packet size of DDoS traffic.  - 8 million packets per second and 98Gbps throughput, based on 1,500 bytes packet size of DDoS traffic. Generate DDoS variants: XproNS provides configuration templates for common types of DDoS attacks. Test engineers can define and edit more complex attack signatures themselves. #testing #DDoS
