TCP Cluster Persistence
The TCP Cluster Configuration Persistence screen is used to configure
Sticky Netmask
values,
Timeouts and assign the Inter Cluster sticky flag to the selected TCP cluster. It can be accessed by
selecting a cluster from the left navigational pane and selecting the
Configuration > Persistence
tab.
Sticky Netmask
Enables sticky network aggregation for a subnet. Sticky network aggreg-
ation is applicable for Layer 4 and Layer 7 clusters. Sticky network aggreg-
ation enables Equalizer to correctly handle sticky connections from ISPs
that use multiple proxy servers to direct user connections. When you
enable sticky network aggregation, all the connections coming from a par-
ticular network are directed to the same server. (Typically, all the servers
in a proxy farm are on the same network.) The sticky netmask value indic-
ates which portion of the address Equalizer should use to identify par-
ticular networks. Values are:
0-32
for IPV4 clusters (default=32)
0-128
for IPV6 clusters
Inter-Cluster Sticky
With the
inter-cluster sticky
option, you can configure Equalizer to dir-
ect requests from a client to the same server on any available port that has
a current persistent connection in any cluster.Inter-Cluster Sticky is a
Layer 4 option that allows you to extend Layer 4 persistence across mul-
tiple server ports.
Sticky Time Out
Sticky Timeout is the number of seconds that Equalizer should “remem-
ber” connections from clients. Valid values are from 0 (which disables
sticky connections) to 1073741823 seconds (or over 34 years). For more
information, refer to
"Enabling Sticky Connections"
on page 371
