You're welcome.

The SLA is negotiated between ISP and customers or between ISPs. If such contract is set up it is put into PDB which is used by BB. BB control edge routeror negotiate with other BB by COPS.

It does not need any algo. but a protocol, as COPS.  

To the bandwidth allocation between different service classes, RDM or MAR is proposed for DS-TE but it does not limited to that area. MPLS is a transport protocol which enables QoS differentiation and TE in packet networks.
