Thanks a lot Mooney for the help.

> One option is Diffserv and using DSCP for prioritizing different traffic, There are other QoS methods available but in MPLS core - this is more common.

I was thinking along the same direction, but was worried if I am missing 
the point. Since, class of service feature in MPLS and the traffic 
parameters of CR-LDP were confusing me.

So Mooney, that means ideal for me would be to use Diffserv for 
prioritizing different traffic and MPLS for TE and explicit routing. Am I 
right?  I am creating different traffic classes for different kinds of 
traffic (like CBR constant bit rate traffic class for voice) and then 
providing the QoS gurantees through it. And that means I should use 
DiffServ for prioritizing traffic and MPLS for explicit routing for 
creation of respective traffic class. Is it done presently in the 
networks and what are the issues for me to focus for solving which are 
yet unsolved? Is it the right approach or there can be a better way to do it?


> When you say end to end do you mean desk top to desk top or do you mean PE to PE? Most service providers only provide SLAs from PE to PE and the customer needs to provide QoS that can mark the QoS using the same methodology as the service provider.

In my work, reservation would be for PE to PE only, but the application 
on the desktop would be able to specify its QoS requirement (jitter, 
delay, throughput) which is guranteed by the MPLS core network (assuming 
no QoS contract infringement at the customer network i.e. from desktop to 
PE takes place). I am drawing ideas from Aquila architecture of European 
IST for the work. But that deals with only DiffServ network.

Thanks again for the help.
