Quality of Service
Quality of Service (QoS) features enable differential treatment of network traffic types to support
special applications or extend priority access to designated groups of users. For example,
applications as streaming media and voice over Internet suffer serious quality degradation if data
transmission is interrupted or bandwidth fluctuates excessively. You can assign a higher quality of
service to applications of this type, while still maintaining adequate service for less intensive
applications such as print and file sharing. Network utilization is increased with little to no negative
effect on user productivity. QoS can also be used to lower the priority for non-critical applications.
For example, FTP transfers, which are generally not time critical but can consume significant
network bandwidth, can be assigned lower priority than streaming media applications or database
transactions.
QoS can also be assigned on a user group basis. For example, network administrators can be
assigned a higher quality of service than other employees, thereby enhancing their ability to
manage and troubleshoot a heavily loaded network.
Airgo implements quality of service features using classes of service (COS). Eight COS levels are
available for assignment according to user or application based rules. The COS approach does not
guarantee bandwidth, but it does give “best effort” priority according to the assigned level. A
flexible approach to service quality, it scales easily and accommodates a variety of mapping rules.
MAC layer mappings for COS levels and COS to IP layer mappings are supported, and priority
settings can be assigned for different COS mapping rules.
IP Routing
IP routing adds flexibility to AP management and expands the addressing capability of the AP. You
can specify static IP addresses outside the local subnet along with routing information to reach the
addresses.
Multiple SSIDs
The Airgo AP supports multiple SSIDs within each individual AP. Using the multiple SSID feature,
users can access separate networks through a single physical infrastructure. For example, if you
want to create different levels of resource access for employees and visitors, you can create two
SSIDs, one with high security and one with open security.
Guest Access
The Airgo AP supports flexible, secure managing of guest access at corporate locations. By
contrast with most other guest access solutions, the Airgo AP supports guest access without
requiring any changes to the physical network topology. VLAN tags on the existing access points
segregate users into corporate and guest VLANs, and guests are automatically directed to an
internal or external web landing page. Guest passwords can be assigned statically or change
dynamically according to a pre-set schedule. An open access option is available to provide
unauthenticated guests with access to an open subnet.
Rogue AP Detection and Classification
Maintaining a secure wireless network requires ongoing monitoring of potential rogue access
points and the ability to classify them as known to the local or neighboring network, or as true
rogues. The network management functions of NM Portal include automatic network scanning and
display of all the detected APs that potentially qualify as rogues. Using the information included in
