Session Limit
This new feature allows to drop the new sessions from both WAN and LAN side. If the new
sessions number are exceed the maximum sessions in a sampling time.
Figure 24: Session Limit
Session Limit
Sampling Time
The period to count the new session. Only those new sessions
occurred in the most recently sampling time were be count for limit
checking.(Default is 400 mil-sec)
Maximum of Total New
session
If the number of new sessions for system exceed the maximum in the
Sampling Time. Any new sessions in the system will be dropped.
(Default: 65535 session/sec)
Maximum of New
Sessions for Host
If the number of new sessions for the host exceeds the maximum in the
sampling time. Any new session of the host will be dropped. (Default:
session/sec)
Maximum of Dropped
New Sessions for Host
If the number of dropped new sessions for the host exceeds the
Maximum in the sampling time, any new session of the host will be
dropped for the pause time.
Pause Time
Within the pause time, no new session of the suspended host could be

6: QoS Configuration
Overview
The
Load Balancer provides QoS, which supports the high quality of network service.
Because it will classify outgoing packets based on some policies defined by users, make some
real-time applications to get better response or performance.
QoS Setup
The following web page management are guiding you how to setup QoS and make QoS work.
Figure 26 QoS Setup
Data – QoS Setup.
QoS Feature
±
Enable QoS
– This will allow users enable QoS function.
•
Queuing Method
– The methods that how you manage your queue.” Priority
queuing”. It is one of the first queuing variations to be wildly implemented.

IP TOS ( Type
of Service)
Feature
•
Process TOS Field
–An 8 bits field in the IP packet header designed to
contain values indicating how each packet should be handled in the network.
If you choose "enable" then it will enable this function to process IP Type of
Service field.
•
Overwrite policy priority
– Choose “yes” to set the priority of TOS field in IP
packet overwrite the priority defined in policy configuration
Policy Configuration
When you use QoS, you must define some policies to make some packets to have higher priority
to pass through.

Admission
Policy
This section identifies each policy
•
Policy Name List
– When adding a new Policy, ignore this list. To edit an
existing entry, select it from the list, and click the "Select" button. The data
fields will then be updated with data for the selected entry.
•
Policy Name
– Enter a suitable name. Generally, you should use the "Policy
Name" for the network traffic.
•
Source Address
– Define the source address of packets here. It has two
types like IP address or MAC address. If you select IP address, you can
define IP address range, otherwise define up to four MAC addresses.
•
Destination Address
– Define the destination address of packets here. The
explanation is as the same as above.
•
Protocol Type
– The field defines traffic packet type, i.e. IP,TCP and UDP.
•
Source Port
– Define the source port of packets here.
•
Destination Port
– Define the destination port of packets here.
•
Priority Queue
– It defines a packet if it meets all conditions defined above, it
will be serviced with some priority level.
