Boson's licensing model is cumulative just like Cisco certification levels. Each Boson license maps specifically to a Cisco certification exam, and includes the labs for the preceding exams, too. This licensing model is easy to understand, relatively affordable, and provides a large number of built-in labs for each exam.

If you find structure important, this is really convenient. Lab Quality. While the number of labs you receive depends on the price, every Boson lab is high quality and tailored to a Cisco certification exam. Each lab comes with detailed instructions regarding what needs to be configured and verified within the related network topology. Furthermore, most labs ask insightful questions about the output of commands observed in the CLI of the networking device, which helps reinforce understanding about what is being configured and why it needs to be configured.

Just like Packet Tracer, each lab is graded for completion and accuracy within the application. However, where Boson NetSim differentiates itself from Packet Tracer is the ability to track completion of labs from within the application.

This feature allows you to view your completed labs, attempted labs, and un-attempted labs at a glance. It is worth noting here that Cisco's NetAcad courseware also offers labs through Packet Tracer exercises as well as hands-on labs with physical equipment. However, the focus of this article is reviewing the Packet Tracer software itself, not the NetAcad courseware.

Boson's software revolves around purchased lab activities in addition to a sandbox. This is a feature and advantage that NetSim holds over Packet Tracer, which requires your to either get creative or source labs from NetAcad. Lab Accessibility. All purchased Boson labs are easily accessible from within the application, unlike Packet Tracer. There is no need to download labs through individual files and import them into NetSim — all labs are downloaded, completed, and graded from within the application itself.

This lets you focus your time on labbing exam topics rather than downloading files and setting up the lab. Custom Lab Distribution. If you create a network topology that you'd like to share with the world, you can easily upload the topology to the NetSim Community. Conversely, you can browse other people's uploaded topologies and download them from within the application. As previously mentioned, there is no need to download a separate topology file and import it as is done with Packet Tracer.

Realistic Terminal Features. Copy and paste is very realistic in NetSim. In a real terminal, highlighted text is automatically copied to the system clipboard. You paste with a right-click. NetSim's terminal mimics this function. This realistic feature sets NetSim apart from Packet Tracer, where this is not supported. By default, terminals are tabbed, so each device's terminal appears within its own tab, unlike Packet Tracer where each terminal gets its own window. If this is not desired, you may place a tab in its own window by right-clicking the tab and selecting the "Float" option.

Alternatively, you can drag the tab outside of the terminal window to accomplish the same task. In fact, the entire interface of NetSim boasts this UI — just about every window can be docked and undocked with ease so that the interface is customized to suit your preferences. In NetSim, if a network device can be customized through the addition of modules which it calls "Addons" , the software explicitly asks what modules you would like to insert in the device when the device is added to a network topology.

Additionally, NetSim calls out the type of interfaces that each module adds. For example, if you want to add an HWIC-2T network module to a device, NetSim explicitly tells you that the addition grants two additional serial interfaces that the device can use.

Finally, once a device has been customized and added to the network topology, a device with the same physical configuration is saved in the "Recent Devices" window. This modified device can be easily added to the topology by dragging it from the "Recent Devices" window into the network topology. Less clicking than Packet Tracer.

In Packet Tracer, you must place a device in your network topology, manually power off the device by clicking on the power switch , drag the desired network module to the desired slot, then manually power on the device by clicking on the power switch. Furthermore, this process needs to be repeated for each device that needs its physical configuration modified. If you need to test a topology in Packet Tracer with eight routers using serial interfaces, modifying each device results in a lot of clicking.

Lack of Topology Information. The network topology window shows a limited amount of information, especially while a simulated topology is running. For example, you can't see the link state of each connection between network devices, nor do you have any indication that the device is actively transmitting data. The primary source of feedback for this type of information is the device itself. While this could help prepare you for a role as a remote network administrator where physical access to devices is not possible, the additional feedback in simulation would be particularly helpful for visual learners.

Lack of Topology Customization. Unlike most other network simulators and emulators, NetSim does not have a way to add colorized shapes to a network topology. Aside from network devices and connections, you can only add text-based notes and labels to the topology. This is a fairly minor point, but is important when rehearsing some exam topics, such as multiarea OSPF, where colored shapes illustrating the different areas comes in very useful.

Cannot Modify Active Topology. Once a network topology is running, you can't modify it until you stop the topology, which shuts down the simulated network devices. If you need to add a new network device or a new connection to your network topology, you must stop the entire topology, modify it as needed, then start the topology once more. This is a minor point, as the topology itself starts and stops very quickly, but the less time you spend managing simulator, the better!

No Simulation Mode. There is no way to place NetSim's network topologies into a "simulation mode" like one can with Packet Tracer. There is no way to view the contents of individual packets as they traverse the network in NetSim. All network devices are simulated in real-time. As a result, you can't visualize the path of a packet throughout your simulated network the same way that you can in Packet Tracer.

No Cross-Platform Compatibility. It is not supported on macOS or any Linux distribution. Boson NetSim's strongest feature is the built-in labs that directly map to the exam topics of specific Cisco certification exams. For existing patrons of Boson's courseware and practice exams, these labs are an excellent practical aid for reinforcing networking concepts.

The fact that labs whether they were built by Boson or built by the community can be accessed directly through the NetSim application simplifies the labbing experience and lets you focus on learning instead of prerequisite tasks. The software's weakness is in the creation, manipulation, and interaction of network topologies in the sandbox environment.

It is more difficult to create aesthetically-pleasing network topologies in NetSim compared to other network simulators and emulators. An active network topology does not provide very much visual feedback regarding the status of devices, links, and transmission of data. NetSim's simulated Cisco IOS software has small quirks not exhibited by actual Cisco IOS software, particularly when using context-sensitive help or executing non-existent commands, which is a common mistake that many networking novices make.

Finally, while NetSim's terminal emulator has some features that cannot be found in Packet Tracer's terminal emulator, Packet Tracer's wider support for keyboard shortcuts presents a more tactile CLI experience. Now that we have reviewed the two pieces of network simulator software offered on the market, let's dive into emulators!

An emulator is a piece of software that runs and connects virtual network devices together. Emulators virtualize real network devices, and virtual network devices tend to offer a more advanced feature set compared to network devices present in simulators. The behavior exhibited by virtual network devices is more representative of how real physical network devices would behave in the real world. However, there are tradeoffs between simulators and emulators.

Emulators tend to be limited in the types of virtual network devices that they support, as well as how those virtual devices can connect to each other. Furthermore, depending upon the specific software used, you will need to locate a binary image file of the virtual network device that you would like to emulate, as well as the appropriate licensing.

These resources are typically acquired through a support contract with a networking vendor. Finally, because emulators are virtualizing real network devices, their system requirements demand much more processing power, memory, and storage space compared to network simulators. In fact, some network emulators require a separate server virtualized or otherwise to be deployed in order to function!

It is a Python-based platform that primarily utilizes software called Dynamips to emulate Cisco software and hardware. Since Dynamips supports the Cisco , , , , , , and router platforms, GNS3 also supports these same platforms. In recent years, GNS3 has evolved to support a larger scope of virtual network devices from a variety of vendors through the use of "appliances", which are easy-to-import templates of common virtual network devices.

Once installed, you can create network topologies through the client, which are executed on the server. If a user finds a bug with the software, they can report it, and a member of the community or even the user themselves! The fact that GNS3 is open source has a number of advantages. For one, if the software is exhibiting unexpected behavior and you think it's a bug, you can review the open issues to see if other users are experiencing similar behavior.

Those with software development backgrounds or those who want to start learning software development can copy GNS3's source code known as forking the code and customize it to their preference. That means you can develop new features that can be pulled back into the main project as a contribution to the community. In short, participating in an open-source project improves the software, helps others, and can build your reputation among fellow network engineers.

For those not interested in software development, contributing to open-source projects can often be done by writing or improving the project's documentation. There is always a need for helpful individuals to assist other users with troubleshooting issues — and documenting them. The greatest advantage to the open-source nature of GNS3 is the community. You will benefit from the positive feedback loop created by a group of like-minded people who want to help others learn, work, and play.

Simple, Easy-to-Read Documentation. GNS3 documentation is one of the best among open source projects. Whether you're just getting started or need guidance on advanced configuration, GNS3 most likely has excellent, well-written documentation for you task — complete with pictures. Modifiable Active Topology. In GNS3, each virtual network device can be started and stopped independently of other virtual network devices. As a result, there is no need to stop all network devices in order to add a single new network device, nor is there a need to stop any network devices in order to add new connections between devices.

This feature is similar in behavior to Cisco's Packet Tracer, making it a popular choice for Packet Tracer users transitioning to a network emulator. Multiple Connection Types. GNS3 not only supports Ethernet connections between network devices, but also allows for serial connections between devices that support serial network modules.

This is a must-have feature for those studying for the CCNP ROUTE exam, which has exam topics requiring knowledge of serial technologies such as Frame Relay, which can only be configured over serial interfaces. Community Labs. The GNS3 Marketplace, which is often used to distribute and install network device appliances, has a section that allows you to exchange network topologies for the purposes of labbing specific technologies.

Importing and exporting network topologies from this marketplace can be difficult at times due to other users utilizing different network device software images. However, the marketplace can still be used as a source of inspiration for network topologies relevant to specific technologies.

Software Image Access. GNS3 does not come prepackaged with any virtual network devices. In other words, the only legitimate way to obtain these Cisco IOS software images is to have a valid support contract with Cisco that provides access to these images — or be a student. If Cisco's Packet Tracer is the gold standard in virtual network simulators, then GNS3 is the gold standard in virtual network emulators.

GNS3's mature, open-source community has created a feature-rich, well-documented piece of software that is completely free. This is not GNS3's fault. But those images are a factor that you must keep in mind prior to deploying GNS3 for personal or commercial use.

It is very similar to Cisco Modeling Labs better known as CML , which is a highly-scalable variant of VIRL designed for medium and large businesses to model and emulate enterprise networks. Version: VIRL was evaluated using version 1. The nodes used for evaluation included IOSv Instead, they consider the VIRL subscription as a legitimate method to get up-to-date software images. Network Topology Portability. If you want to share a network topology a friend, colleague, or execute it on another VIRL server, exporting the network topology is easy.

Advanced Automation Capabilities. VIRL includes a feature called AutoNetKit, which allows basic configuration of features on nodes to be automatically populated across the entire network topology. This feature is useful if you need to quickly test the behavior of a specific technology or virtually recreate an existing network. However, it is not very useful when studying for Cisco certifications because it can prevent you from building muscle memory when configuring, verifying, and troubleshooting networks.

However, the Personal Edition license only allows a total of 20 nodes meaning, 20 network devices to be running at a single time across all active simulations. Resource Requirements. VIRL requires more processing power and memory compared to other solutions. The minimum system requirements are 8GB of memory and four CPU cores allocated to the virtual machine.

Needless to say, if you plan to use any nodes outside of the IOSv devices, memory must be allocated accordingly. No Serial Interfaces. The aptly named Design view is for placing and connecting nodes, as well as defining automated and manual configuration for each node.

The Simulation view allows you to manage and connect to network devices that are actively running. Once a topology is running, you can't modify the topology. You can't add or remove nodes, or add or remove the connections between nodes. This can result in a lot of wasted boot time. Future releases are expected to change this particular issue. This enhancement comes alongside other excellent changes, such as the elimination of the VM Maestro thick client in favor of an HTML5 web client, an improved licensing scheme, and lower base resource requirements.

An annual subscription to VIRL grants you access to network device software images. That's probably it's greatest benefit for the money. Remember that these software images are typically only available with a service contract or through a college program.

If you're not a student or otherwise have access to these images, VIRL is the only semi- affordable method for the average test taker to obtain them. In fact, VIRL offers a number of features that cannot be found in either of its competitors, particularly with respect to configuration automation! At the time of writing, VIRL has a number of drawbacks, such as the base resource utilization of the VIRL server appliance and the lack of support for serial interfaces.

The good news is that many of these weaknesses are planned to be resolved in a future software release. However, until this update is released to the public, you should weigh these cons when considering deploying VIRL. In other words, you don't need to download and install a separate application in addition to the server to virtualize, connect, and configure network devices.

You simply deploy the server through a bare-metal installation or virtual machine, and everything else can be done through the HTML5 client.

As a result, network devices that are inside a simulator are restricted to the commands and features programmed into the simulation. This is the reason; various advanced features like that of DMVPN, Policy Based Routing, and so on, real network devices are capable of are not available in simulated counterparts. The main benefit of these simulators is that these tend to be extremely lightweight. Simulator software can work on just about any modern computer in the absence of worrying about processor, memory, or even storage needs.
