Step 6 Quality of Service Setup page
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 (Max Bandwidth field). The total bandwidth allocated to all groups combined cannot be more than 90 percent of Max Bandwidth.
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.
