The EE2400-SS can recognize QoS priority information from the incoming packets
to send the packet to different priority queue for different service priority. The
EE2400-SS identifies the packet’s priority based on 3 type of QoS priority
information: 1) Port based priority; 2)802.1p/Q VLAN tag; 3) The TCP/IP
TOS/DiffServ (DS) priority field. These 3 types of QoS can be configured by
hardware pins, EEPROM or Registers 0x0400, 0x0401.
EE2400-SS support 2 level priority queues. The queue service rate is based on the
packet based Weighted Round Robin algorithm. The packet based service weight
ratio of high-priority and low-priority queuing can be set as 4:1, 8:1, 16:1 or "Always
high priority first”.
