This document describes an NSIS QoS Signaling Policy model for networks
that use the Resource Management in Diffserv (RMD) concept. RMD is a
technique for adding admission control to Differentiated Services
(Diffserv) networks. RMD complements the Diffserv architecture by pushing
complex classification, conditioning and admission control functions to the
edges of a Diffserv domain and simplifying the operation of internal nodes.
It allows feedback to systems outside of the Diffserv domain on the
availability of resources for individual sessions within the domain while
having the availability to aggregate inter domain (end-to-end) resource
reservations at the edge of the domain to reduce the burden on internal
nodes. The RMD QoS Signaling Policy Model (RMD-QSP) allows devices to use
the NSIS QoS-NSLP protocol to signal reservation requests from devices
outside the Diffserv domain to edge nodes in the domain, edge nodes have
the availability to aggregate the requests and signal the aggregated
requests through internal nodes along the data path to the egress edge
nodes, and for Egress Edge nodes to signal the original, disaggregated,
requests to outside devices.
