Classification Criteria
The frames associated with a particular BWM contract are specified, using the parameters
listed below. All of these classifications are aimed at limiting the traffic outbound from the
server farm for bandwidth measurement and control.
Server Output Bandwidth Control
n
Physical Port - All frames are from a specified physical port.
n
VLAN - All frames are from a specified VLAN. Even if a VLAN translation occurs, the
bandwidth policy is based on the ingress VLAN.
n
IP Source Address - All frames have a specified IP source address or range of addresses
defined with a subnet mask.
n
IP Destination Address - All frames have a specified IP destination address or range of
addresses defined with a subnet mask.
n
Switch services on the virtual servers
The following are various Layer 4 groupings:
o A single virtual server
o A group of virtual servers
o A service for a particular virtual server
o Select a particular port number (service on the virtual server) within a particular vir-
tual server IP address.
The following are various Layer 7 groupings:
o A single URL path
o A group of URL paths
o A single cookie
Application Bandwidth Control
Classification policies allow bandwidth limitations to be applied to particular applications; that
is, they allow applications to be identified and grouped. Classification can be based on any fil-
tering rule, including those listed below:
n
TCP Port Number - All frames with a specific TCP source or destination port number
n
UDP - All UDP frames
n
UDP Port Number - All frames with a specific UDP source or destination port number
