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.
Open source programs should receive the attention of students since they are free to download and use. Dynagen is one such program, of which is built with the Dynamips simulator. Dynagen is one of two software packages that currently works with Dynamips, and is often described as being the less friendly of the two. Documentation is also lacking for those with questions.
Dynamips also has GNS-3 to work with. Between Dynagen and GNS-3, GNS-3 is used more frequently among students. Students that are just beginning will be turned away from the difficult use of Dynagen. Luckily, GNS-3 has a forum, video documentation of using the program, and plenty of helping supporters. Students that are self-learning and not in a Cisco class will find this computer network simulator to be one of the finest of the bunch.
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.
Not all network simulators are desktop simulations. You can find some simulators available over the Internet through web browsers, using technology such as Java or JavaScript. You will find that these web-based programs can be less expensive, and some free, but you will have to have a connection to the Internet to access it. Thus, it could be hard studying if you don’t have access to the Internet.
In Conclusion
The choices in programs is somewhat limited, due to the advanced technology that goes into creating network simulations. The best, by far, is the Cisco Packet Tracer suite, but if you can’t obtain it, start looking into open source alternatives to use for study time.
