3.5.3.1 Port Based Priority<br />
When you click Port Based Priority, it will show the following:<br />
Select the ports to which the rule should be applied.<br />
These six ports can be applied: LAN1, LAN2, LAN3, LAN4, DSL and Sniffing<br />
The Scheduling <strong>Co</strong>nfiguration item can setup the queue type from type 0 to type 3. Each<br />
queue type can set the queue weight from 1 to 15.<br />
The Queuing method is to configure queuing algorithms for outgoing traffic. Queuing<br />
algorithms allow <strong>EFM</strong> modem to maintain separate queues for packets from each individual<br />
source or flow and prevent a source from monopolizing the bandwidth.<br />
The queuing algorithms:<br />
WRR Weight Round Robin<br />
BE<br />
SP<br />
Best Effort<br />
Strictly Priority<br />
SP (Strictly Priority) services queues based on priority only. As traffic comes into the <strong>EFM</strong><br />
modem, traffic on the highest priority queue, Q3 is transmitted first. When that queue empties,<br />
traffic on the next highest-priority queue, Q2 transmitted until Q2 empties, and then traffic is<br />
transmitted on Q1 and so on. If higher priority queues never empty, then traffic on lower<br />
priority never gets sent. The SP class is typically for video applications that require a fixed<br />
amount of bandwidth to be considered good quality.<br />
