Hi there,


Just wondering if anyone out there has either implemented or looked into 
this queuing method for quality of service implementation.
This solution is offered (hardware solution) and patented by 
foursticks.com. According to foursticks, "HCQ achieves the efficiency 
and flexibility of first generation queuing systems, without the 
disadvantages."

It compares HCQ (interesting reading) w/ Class-Based Queuing (CBQ), 
Random Early Discard (RED) and Weighted Random Early Discard 
(WRED),Weighted Fair Queuing (WFQ),Priority Queuing (PQ) & Low Latency 
Queuing (LLQ).


Also can anyone recommend a qos forum which I can ping as well.


Any insight will be appreciated.


regards,
/vicky
