Cisco Packet Tracer 网络模拟工具

思科^(Cisco)是网络^(Networking)领域的巨头。它的Packet Tracer已经统治了市场多年，并且看起来将继续这样做。

在Cisco Packet Tracer的帮助下，可以创建简单和复杂的电路，用于复制现实生活场景。因此，现在您可以实施您的计划并测试电路是否有效工作，而无需在硬件上花费一分钱。

它具有所有类型的电线，无论是光纤、同轴电缆等。它由大多数现代Cisco 路由器^{(Cisco Routers)}、无线^(Wireless) 设备^(Devices)、WAN 仿真^{(WAN Emulation)}以及创建电路所需的许多其他设备组成。

Cisco Packet Tracer相对于应用程序的另一个优势是它是CCNA认证培训期间使用的应用程序。

Cisco Packet Tracer免费替代软件

Cisco Packet Tracer的一些最佳免费替代品是

图形网络系统3
NetSim 网络模拟器
EV-NG
网络++

让我们详细谈谈它们。

1.图文网络系统3

GNS3或图形网络^{(Graphic Network)}是最好的Cisco Packet Tracer替代方案之一。它具有Cisco Packet Tracer等所有功能和Wessel^(Wessels)功能，这意味着它包含大量工具，例如ASA、ATM 交换机、以太网集线器、以太网交换机^{(ASA, ATM Switch, Ethernet Hub, Ethernet Switch)}和许多其他设备。

它适用于所有三个主要平台，Windows、Mac和Linux，并帮助用户使用相同口径的设备创建虚拟环境以匹配现实世界。因此，您不必在不知道它正在工作的情况下制作物理电路。

您可以从他们的官方网站^{(official website)}下载适用于您各自操作系统的应用程序。

2. NetSim 网络模拟器

我们列表中的下一个免费应用程序是NetSim Network Simulator。它是一个简单的应用程序，可以安装在Windows PC 上以设计网络电路。

它主要用于研究和开发，因为您可以设计物理电路的复制品而无需花费一分钱。他们拥有所有必要的工具，例如路由器、交换机、WinPC、IP 电话、帧中继交换机^{(routers, switches, WinPC, IP Phone, Frame Relay Switch)}。
NetSim Network Simulator可以从他们的官方网站^{(official website)}下载。

3] EVE-NG

EVE-NG 是重度软件，容量为 5.1 GB，与本文中提到的所有其他软件不同。

它具有完整的HTML 5 UI、点击播放拓扑、将真实网络转换为虚拟化的能力等等。

但是，就像Cisco Packet Tracer一样，您可以使用其广泛的设备来创建拓扑。

您可以从他们的官方网站^{(official website)}下载 EVE-NG 。

4. 全网++

最后但并非最不重要的一点是，我们有 Omnet++。它是基于 C++ 构建的开源网络模拟器，适用于Windows、Linux和MAC OS。

这个软件中有很多东西，但我们在这里谈论它的网络构建工具。您可以通过自己编写设备或只是拖放来添加设备，后者是使其成为Cisco Packet Tracer替代品的原因。

它有许多不同的设备，如路由器、交换机、光纤等^{(routers, switches, fiber, etc)}。其令人兴奋的功能之一是可以构建它以测试新的 5-G 基础设施。

Omnet++ 可以从他们的官方网站^{(official website)}下载。

用物理设备构建网络可能有点不协调，同时也很昂贵。这就是我们拥有Cisco Packet Tracer及其替代品的原因。您可以在这些应用程序上进行虚拟网络电路检查它是否正常工作，然后构建最终网络以提高效率。希望本文能帮助您找到最适合您网络需求的网络模拟器工具。^(Simulator)

Cisco Packet Tracer Networking Simulation Tool and its free alternatives

A Network engineer knows the impоrtancе of a gоod Networking Simulation Tool. Cisco Packet Tracer is one such tool that has ruled the Networking market for ages. But it is not the only tool in the market, that’s why in this article, we are going to see some of the best Cisco Packet Tracer alternatives.

Cisco Packet Tracer Networking Simulation Tool

Cisco is a giant in the Networking space. Its Packet Tracer has ruled the market for ages and looks like will continue to do so.

With the help of the Cisco Packet Tracer, one can create both simple and complex circuits that can be used to replicate the real-life scenario. So, now you can implement your plans and test if the circuit is efficiently working or not without spending a penny on the hardware.

It has all types of wires be it fiber, coaxial, etc. It consists of most of the modern Cisco Routers, Wireless Devices, WAN Emulation, and many other devices that you need to create a circuit.

Another advantage Cisco Packet Tracer has over apps is that it is the very application that is used during CCNA certification training.

Cisco Packet Tracer free alternative software

Some of the best free alternatives of Cisco Packet Tracer are

Graphic Network System 3
NetSim Network Simulator
EVE-NG
Omnet++

Let us talk about them in detail.

1. Graphic Network System 3

GNS3 or Graphic Network is one of the best Cisco Packet Tracer alternatives. It has all the bells and Wessels like Cisco Packet Tracer that means that it consists of plenty of tools such as ASA, ATM Switch, Ethernet Hub, Ethernet Switch, and many other devices.

It works on all three major platforms, Windows, Mac, and Linux, and helps the user in creating a virtual environment with devices of the same caliber to match the real world. Because of this, you don’t have to make a physical circuit without knowing that it’s working.

You can download the application for your respective operating system from their official website.

2. NetSim Network Simulator

The next free application on our list is NetSim Network Simulator. It is a simple application that can be installed on Windows PC to design a networking circuit.

It is mostly used for research and development as you can design a replica of a physical circuit without spending a penny. They have all the essential tools such as routers, switches, WinPC, IP Phone, Frame Relay Switch.
NetSim Network Simulator can be downloaded from their official website.

3] EVE-NG

EVE-NG is heavy software, coming at 5.1 GB it is different from all the other software mentioned in this article.

It has a full HTML 5 UI, click and play topology, the ability to transpose real network to virtualization, and many more.

However, just like Cisco Packet Tracer, you can create a topology by using its wide range of devices.

You can download EVE-NG from their official website.

4. Omnet++

Last but not the least, we have Omnet++. It is an open-source network simulator built on top of C++ for Windows, Linux, and MAC OS.

There are a lot of things present in this one software but we are here to talk about its network-building tool. You can add devices by either writing them yourself or just dragging and dropping, the latter is what makes it a Cisco Packet Tracer alternatives.

It has many different devices such as routers, switches, fiber, etc. One of its exciting features is that it can be built to test the new 5-G infrastructure.

Omnet++ can be downloaded from their official website.

Building a network with physical devices can be a bit jarring and expensive at the same time. That’s why we have Cisco Packet Tracer and its alternatives. These are the applications on which you can make a virtual network circuit check if it’s working and then construct the conclusive network to be efficient. Hopefully, this article has helped you in finding the best Network Simulator tool for your networking needs.
