24-Port Managed Gigabit Switch
DSCP specifies a particular per-hop behavior that is applied to a
packet. The first 3 bits means IP precedence with the range of 0~7;
and the next 4 bits means ToS priority with the range of 0~15.
RFC2474 redefines the ToS field in the IP header as DS field. So
DSCP utilizes the first six bit in this field from (0~5bit) with the
available value of 0~63, and the last two bits (6, 7 bit) are reserved.

3.12.3 Scheduling Mechanism
When the network traffic is congestive, usually scheduling mechanism is
deployed to solve the traffic order. TEG3224T supports two ways: SP
(Strict-Priority) and WFQ (Weighted Fair Queuing). This part allows you
to select WFQ or Strict scheduling mechanism for emptying the priority
classes. When the Strict scheduling mechanism is used, the packets will
be emptied by the priority order, For example, key applications as VoIP,
on-line gaming, etc configured with high priority are transmitted first.
When the WFQ (Weighted Fair Queuing) is used, WFQ will sort out
packets by different application, IP priority and Hash mode into different
queues (Low, Normal, Medium, High). Dring times of peak network
traffic, high queue traffic will share the network bandwidth with other
traffics by the slected proportion.
