ABSTRACT
We have been asked for our end of academic curriculum's
project to work on a technology for network infrastructures management and
administration namely «THE Mikrotik Technology». The study and the
deployment of the various modules, which are part of this technology, should
allow us to solve some issues faced by some users of that technology such as
networks administrators, ISP and private. Indeed, among those major
difficulties, we have:
· Bandwidth test and management.
· Security rules implementation on the router.
· Users managements.
· Saving and backup of data inside the router in case of
crash.
· The implementation of wireless network and its
securing.
We had to overcome those difficulties, while emphasing on the
WIFI part, which was the part of the work we had to cope with. We have first
installed Mikrotik with the installation CD. Then, we have configured the
basics elements for an access to internet such the NAT and DHCP functions.
Finally, we have implemented the adopted operating mode which was the
infrastructure mode and have deployed and emphasized on the different security
modes of our wireless network as defined in the specification of the
project.
