Progressing MAR

["Ash, Gerald R (Jerry), ALABS" <gash@att.com>]

All,

A specification for the Maximum Allocation with Reservation (MAR) bandwidth constraint (BC) model is proposed in http://www.ietf.org/internet-drafts/draft-ash-mpls-dste-bcmodel-max-alloc-resv-01.txt.  

MAR is an extension of the Maximum Allocation Model (MAM).  MAR is similar to  MAM in that a maximum bandwidth allocation is given to each class type (CT).  However, through the use of bandwidth reservation and protection mechanisms, CTs are allowed to exceed their bandwidth allocations under conditions of no congestion but revert to their allocated bandwidths when overload and congestion occurs.  

Analysis is presented in an ANNEX which shows that the MAR model meets all the objectives for BC models, and that it simultaneously achieves bandwidth efficiency, bandwidth isolation, and protection against QoS degradation without preemption.  The analysis information provides critical guidance to users' implementation of the BC models and some important guidelines which users should be aware of before choosing a BC model for their network.

I would like to get a sense of the list for using this I-D as the basis for the MAR specification and for accepting this as a WG document.  

Comments are welcome.

Thanks,
Jerry
