QoS Policy

By setting the

QoS

policy, you can assign a higher/lower priority (based on your

configuration) to received packets to pass through this device. You can define some

policies which classify received packets based on source/destination IP, MAC, port and

protocol type. This feature is useful when the WAN link is very busy or congested or when

using special applications that need real time services such as Internet phone, video

conference...etc.

Policy Priority

•

Policy Name

– The name of a policy which is used to classify

the received packets based on the following types for your

memory.

•

Source/Destination Address, Port

– Specify a packet

based on source/destination address or port. There are two

types of address: IP address and MAC address. By default,

the IP address is 0.0.0.0 for all IP Addresses but the MAC

address is 00-00-00-00-00-00 which cannot be used to

classify.

Port and Protocol Type defines all packets for special

applications.

•

Protocol Type

– The field defines traffic packet type, i.e. IP,

TCP and UDP.

•

Priority Queue

– This device supports four queues. When a

packet meets a policy rule requirement, it will be put into the

52

responding queue. Otherwise it is assigned the lowest priority

to pass through
