RE: [RPRWG] RAH: Re: Minutes of Rate Ad Hoc meeting



Hans,
 
The current draft of the RPR standard tries to achieve several objectives: high link utilization, guaranteed minimum jitter for reserved HP traffic, no packet loss on the ring, etc, and these objectives are conflicting to each other sometimes. One customer may want to disallow any LP packet drop on the ring even this means high jitter for the HP traffic; another may want to guarantee minimum jitter to HP traffic (carrying TDM) at risk of occasionally dropping some LP packets.  
 
My suggestion is that RPR provide a choice for the customer to make his/her decision in conflict resolution.
 
I didn't assume the operator wants to adjust the total load/throughput. Maybe this can be done more easily if the above choice is provided.
 
Regards,
 
Yiming

> Yiming Yao: allow customer to choose between loss, jitter, and utilization

Is the underlying assumption that the operator of the ring (=customer?) wants to
adjust the total load/throughput?  Would this be for loadbalancing purposes?

regards,
Hans
