Hello Kunthea!

The MPLS DiffServ model defines two factors for the packets that are transmitted over an MPLS network: the manner in which the DSCP field and the EXP field are propagated and the PHB such as the CoS and color after the packet leaves the MPLS network. In this manner, differentiated QoS is guaranteed for packets.

Best Wishes!

Hello,
In the DiffServ model, an application does not need to apply for resources from the network before sending a packet. Instead, the application notifies the network node of its QoS requirements by setting QoS parameters of the packet.
Hope to help you!
