Diffserv-aware TE (DS-TE)
Introduces a separate bandwidth pool for constraint based routing of “Guaranteed” traffic
Termed the “sub-pool” as opposed to “global-pool”
Allows us to ensure that “Guaranteed” traffic is always below specified %
Sub-pool represents a more restrictive bandwidth pool for sub-pool tunnels
is used for constraint-based routing and admission of sub-pool tunnels
reflects the bandwidth of a Diffserv queue dedicated to sub-pool tunnels
