16.4 Application and Subnet-based Bandwidth Management
You could also create bandwidth classes based on a combination of a subnet and an
application. The following example table shows bandwidth allocations for application specific
traffic from separate LAN subnets.
16.5 Bandwidth Management Priorities
The following table describes the priorities that you can apply to traffic that the NBG334W
forwards out through an interface.
Table 61 Application and Subnet-based Bandwidth Management Example
TRAFFIC TYPE FROM SUBNET A FROM SUBNET B
VoIP 64 Kbps 64 Kbps
Web 64 Kbps 64 Kbps
FTP 64 Kbps 64 Kbps
E-mail 64 Kbps 64 Kbps
Video 64 Kbps 64 Kbps
Table 62 Bandwidth Management Priorities
PRIORITY LEVELS: TRAFFIC WITH A HIGHER PRIORITY GETS THROUGH FASTER WHILE
TRAFFIC WITH A LOWER PRIORITY IS DROPPED IF THE NETWORK IS CONGESTED.
High Typically used for voice traffic or video that is especially sensitive to jitter (jitter
is the variations in delay).
