I. Introduction
The emerging new technologies and complex network topology requirements in the network field have promoted the continuous development and innovation of network device simulators. As a leading communications technology solution provider, Huawei is constantly committed to providing a better simulation environment for network engineers and technical practitioners. Recently, Huawei launched a new version of the ensp pro simulator (pictured below) to provide users with more performance and functional improvements. This article will conduct a comprehensive evaluation of the ensp pro simulator, focusing on its performance and new functional expansions.
2. Test environment resource configuration
Before evaluating Huawei's new version of ensp pro simulator, you first need to understand the hardware environment and resource configuration used for testing, which will directly affect the performance and stability of the simulator. The following is a detailed description of the test environment and resource allocation used in this evaluation.
We chose a physical machine equipped with AMD 5800h processor and 16GB of running memory as the test platform. This processor is known for its high performance and multi-core design, providing powerful computing support for the operation of the simulator. In the virtualization software VirtualBox, we set the resource allocation to 6 cores and 10GB memory to ensure that the ensp pro simulator can fully utilize the performance of the physical machine and maintain smooth operation when simulating complex network topologies.
Through such a hardware environment and resource configuration, we can provide sufficient computing power and memory resources for the ensp pro simulator, so as to accurately evaluate its performance and resource usage in subsequent tests. Next, we will introduce the test results in various aspects in detail to better understand the actual performance and functional characteristics of the ensp pro simulator.
3. Start performance evaluation
In the evaluation process of the ensp pro simulator, startup performance is an important indicator, which is directly related to the user's experience and efficiency in actual operations. In order to accurately evaluate the startup performance of the simulator, we conducted multiple startup experiments and recorded the time required for each startup.
In the test environment, we used the ensp pro simulator to launch three AR devices at the same time. After many average calculations, we came to a stable result: under the current configuration of the ensp pro simulator, the time required to start three AR devices is about 10 minutes. This time can be regarded as a baseline, providing users with an important reference when configuring and planning experiments.
It is worth noting that the stability of the startup time also reflects the performance of the ensp pro simulator. In multiple experiments, we observed smaller fluctuations in startup time, indicating that the simulator can maintain relatively stable startup performance under different circumstances. This is of great significance to the user's preparation in the early stage of the experiment as well as subsequent operation and debugging.
Taken together, the ensp pro simulator shows stable and expected characteristics in terms of startup performance. Although it may take a long time to start three AR devices, its relatively stable performance can make up for this shortcoming to a certain extent. In actual use, users can plan the startup process in advance to ensure that the functions of the simulator can be fully utilized and effective experimental operations can be performed.
4. Resource usage analysis
In order to gain an in-depth understanding of the resource consumption of Huawei's new version of ensp pro simulator in actual use, we conducted a static routing configuration experiment and conducted a detailed analysis of its resource usage. By observing the CPU and memory usage of the simulator in different operating states, we can better understand the simulator's resource requirements for the test environment.
After completing the static routing configuration experiment, we recorded the resource usage of the ensp pro simulator. According to our measurements, the CPU usage of the emulator in this experimental state is about 60% to 75%, and the memory usage remains roughly around 6GB. This shows that when conducting more complex network configuration experiments, the emulator does consume hardware resources to a certain extent, especially in terms of CPU.
We also compared these measurements to the resource usage expectations given in the product documentation. What is gratifying is that our test results are quite consistent with the expectations in the product documentation, which shows that the resource usage guidance given by Huawei in the documentation is quite accurate. When planning experiments and selecting hardware configurations, users can make reasonable resource allocations based on the recommendations in the product documentation to meet the operating requirements of the simulator.
However, we also noticed that the resource usage of the simulator may further increase in more complex experimental scenarios, especially when involving large network topologies and complex protocol configurations. From a personal point of view, the hardware requirements given in the product documentation seem conservative, and the actual performance requirements may be higher. For users who conduct large-scale experiments or complex scene simulations, they may need to consider using higher-configuration workstations or even server-level equipment to ensure that the simulator can run stably and provide a smooth operating experience.
Overall, the resource occupancy analysis shows the resource requirements of the ensp pro simulator under different experimental conditions, providing users with a reasonable reference basis. By fully understanding the resource consumption of the simulator, users can make more informed decisions in experiment planning and hardware selection to achieve better performance and operating experience.
5. Hardware requirements and performance
Before using Huawei's new version of ensp pro simulator, understanding the simulator's hardware requirements is crucial for users to choose the appropriate hardware configuration. Minimum hardware requirements are usually given in product documentation, however actual performance requirements may vary depending on usage scenarios and complexity.
According to the product documentation of the Huawei ensp pro emulator, the recommended minimum hardware requirements include the number of CPU cores and memory capacity. After our testing and evaluation, we found that these minimum requirements can indeed support the basic operation of the emulator, especially in simple topologies and configurations. However, when more complex network topologies, large-scale experiments, or advanced features are involved, actual performance requirements may exceed the minimum requirements in the product documentation.
Users who wish to conduct large-scale experiments, complex protocol simulations, or perform high-performance operations may want to consider configuring more high-end hardware. Judging from our test results, even under the recommended configuration, the resource usage of the simulator may be high in some cases, which may affect the smooth progress of the experiment. Therefore, users should comprehensively consider actual usage scenarios and requirements when selecting hardware to avoid performance bottlenecks.
Although actual performance requirements may exceed the minimum requirements in the product documentation, this does not mean that the minimum requirements are meaningless. For simple experiments or beginners, hardware configured according to the minimum requirements may be enough to meet basic needs. However, users should reasonably plan their hardware investment based on their actual situation to obtain better performance and user experience.
In summary, the hardware requirements in the product documentation can serve as a baseline, but actual performance requirements may vary depending on different usage scenarios. When selecting hardware configuration, users should consider the scale, complexity, and expected performance of the experiment to ensure that the ensp pro simulator can perform optimally in actual operations and provide support for users' work and study.
6. Function expansion
In addition to performance considerations, the function expansion of the ensp pro simulator is also an important aspect that attracts users. The new version of the simulator has made significant enhancements in this regard, providing users with more choices and possibilities. In this section, we will introduce the functional extensions of the ensp pro simulator and explore the potential value of these new functions in practical applications.
First of all, this new version of ensp pro simulator introduces some new devices, including CE (enterprise router) and NE (single board switch). The support of these new devices enriches the simulator's device library, allowing users to better simulate various network scenarios and conduct experiments and tests more accurately. Especially when building complex network topologies and simulating diverse device environments, the addition of new devices will bring more flexibility to users.
In addition to new device support, the ensp pro emulator also adds a series of new features, including stacking, SRv6 and EVPN, etc. These functional extensions cover network technologies at different levels, from basic device interconnection to more advanced routing and forwarding mechanisms. The introduction of these features provides users with more opportunities to explore new technologies and helps them gain a deeper understanding of cutting-edge developments in the networking field.
In particular, these new features are great for learning about new technologies and experimenting with them. For example, SRv6, as an emerging routing technology, provides a more flexible data packet processing method by introducing the concept of "segment". As a new type of Ethernet virtualization technology, EVPN brings a new solution for the interconnection of data centers and WANs. The support of the ensp pro simulator enables users to learn and experiment with these new technologies in a safe environment, accumulating valuable practical experience.
In general, the function expansion introduced in the new version of the ensp pro simulator has enriched its capabilities in simulation and experimentation. The support of new devices and the introduction of new functions provide users with more choices and learning opportunities, helping them to more fully understand and apply the evolving network technology.
