Attacks from the Internet can be break-in attempts as well as attacks with
the aim of blocking the accessibility and functionality of individual
services. Therefore a LANCOM Wireless DSL is equipped with appropriate
protective mechanisms, which recognize well-known hacker attacks and
which guarantee the functionality.

Quality-of-Service / Traffic management
The generic term Quality-of-Service (brief: QoS) summarizes the functions
of the LANCOM which guarantee certain service qualities. The advantage
is that the QoS functions can take place by means of the existing powerful
classification methods of the Firewall (e.g. limitation of subnetworks,
single workstations or certain services).
Guaranteed minimum bandwidths give priority to enterprise critical appli-
cations, VoIP PBX installations or certain user groups.
