Abstract- QoS routing is the process of routing a connec-
tion based on the connection's resource requirements. The
overhead involved in QoS routing increases with the network
size. State aggregation is an important technique that helps to
reduce the overhead. In this paper, we propose a new state ag-
gregation technique based on "network-flow". Our approach
allows a domain to update the aggregate sent by other do-
mains and keep track of resource availability in other do-
mains. We study the efficacy of our approach with respect to
various network and traffic parameters. Preliminary simula-
tion results show that our approach gives a better bandwidth
admission ratio when compared with existing techniques.
