The CCNA course offered by Cisco is one of the toughest courses a college student can take. It demands mastery of hardware and software that the student may not have outside of the classroom. As a result, students are looking towards Cisco network emulation software more now than ever, so that they may make the grade.

An expensive yet thorough solution is with Boson’s software packaged named Netsim. Netsim ranges in value, from $200 to $500, depending on the licensing and options needed. Netsim is the best bet for instructors, as it comes loaded with plenty of extras such as activities and grading programs. Perhaps less affordable for students, who are usually on a tight budget.

Dynagen is another program, only it’s absolutely free. Dynagen is an open source program that is built on the Dynamips emulator, available free to download at any time. Dynagen is criticized for its lack of an intuitive interface, yet also hailed as a very functional program once it’s learned. For the seemingly learning impaired, there are better options out there.

GNS-3 is another program based on the Dynamips emulator. GNS-3 is more popular among beginners since it has a better interface and better support. GNS-3, or Graphical Network Simulator, has a developer’s forum and video tutorials to get students ready to use the program. It may not have key features that Netsim has, but teachers can still issue this free program to students and have take-home assignments for them to complete.

Self-learners are a breed of students that don’t need classes to obtain their certifications. Although they may be saving money on course costs, they won’t be able to use the best network simulator to date: Packet Tracer. This program is produced by Cisco, who took the time to make the interface amazingly simple to use for such a powerful program. Packet Tracer isn’t available for download to the public, yet if you are alumni or a current student you can access the download area.

There are several web-based programs used with Macromedia Flash and text-based applications that one can look at. These range from free to pricey, just as standalone programs do. Web-based applications can be just as useful, but keep in mind you’ll have to have a constant connection to the Internet to use most of them. Often times it’s just better to get a desktop application for ease of use.

Final Thoughts

You won’t find a much better network simulation package than Cisco’s Packet Tracer. If you can, find a way to get the program either by enrolling in the Cisco Academy or finding other means of getting it. It’s currently the best there is for learning advanced course materials.
