Chapter 25 Bandwidth Management

Table 128 Configuration > Bandwidth Management

LABEL	DESCRIPTION
Outbound kbps	Type how much outbound bandwidth, in kilobits per second, this policy allows the
	traffic to use. Outbound refers to the traffic the ZyWALL sends out from a connection’s
	initiator.
	If you enter 0 here, this policy does not apply bandwidth management for the
	matching traffic that the ZyWALL sends out from the initiator. Traffic with bandwidth
	management disabled (inbound and outbound are both set to 0) is automatically
	treated as the lowest priority (7).
	If the sum of the bandwidths for routes using the same next hop is higher than the
	actual transmission speed, lower priority traffic may not be sent if higher priority
	traffic uses all of the actual bandwidth.
Priority	This field displays when the inbound or outbound bandwidth management is not set to
	0. Enter a number between 1 and 7 to set the priority for traffic that matches this
	policy. The smaller the number, the higher the priority.
	Traffic with a higher priority is given bandwidth before traffic with a lower priority.
	The ZyWALL uses a fairness-based (round-robin) scheduler to divide bandwidth
	between traffic flows with the same priority.
	The number in this field is ignored if the incoming and outgoing limits are both set to
	0. In this case the traffic is automatically treated as being set to the lowest priority (7)
	regardless of this field’s configuration.
Maximize	This field displays when the inbound or outbound bandwidth management is not set to
Bandwidth Usage	0. Enable maximize bandwidth usage to let the traffic matching this policy “borrow”
	any unused bandwidth on the out-going interface.
	After each application or type of traffic gets its configured bandwidth rate, the ZyWALL
	uses the fairness- based scheduler to divide any unused bandwidth on the out-going
	interface amongst applications and traffic types that need more bandwidth and have
	maximize bandwidth usage enabled.
Related Setting
Log	Select whether to have the ZyWALL generate a log (log), log and alert (log alert) or
	neither (no) when any traffic matches this policy. See Chapter 38 on page 485 for
	more on logs.
OK	Click OK to save your changes back to the ZyWALL.
Cancel	Click Cancel to exit this screen without saving your changes.
