Background
QoS is a system that reserves some amount of
bandwidth for critical functions at times when
your Internet connection is at maximum
capacity.
Placing a function under QoS management
means it has protected and uninterrupted
service. Functions not under QoS
management may experience delays and
interruptions during times of data traffic
congestion.
Critical functions are assigned to "QoS
Groups," which then get priority over
unprotected traffic that the BSGX4e is
transmitting out its WAN port.
The upstream bandwidth reserved for the QoS groups is relative to the total amount of bandwidth
available on your upstream Internet connection (
allocated to all groups combined cannot be more than 90 percent of
The wizard configures the two most critical QoS groups for you:
The Voice group is for VoIP phone functions.
The Control group is for network functions that are critical to the BSGX4e's operation.
PPP and ARP are two such functions that get placed into this group.
QoS can protect traffic in both the upstream and downstream directions. Downstream QoS works
differently from the upstream. When downsteam QoS is enabled in one or more QoS groups, the
BSGX4e limits incoming traffic that is not destined for a function protected by one of those QoS
groups. This creates sufficient incoming bandwidth for the protected traffic.
