A Scalable Dynamic Provisioning Mechanism for IntServ{Di Serv Networks for Guaranteed Services

There are various Internet Protocol (IP) QoS support approaches proposed, however no standard interconnection mechanisms have yet been developed to support dynamic provisioning among di erent IP QoS mechanisms. This paper addresses the particular bandwidth management problems of a backbone ISP, a Di erentiated Service (Di Serv) network with an interconnection to an Integrated Service (IntServ) network. This architecture is especially interesting due to the di erent complementary features shared by these architectures. This study proposes mechanisms to realize the scalable dynamic provisioning and admission controlled interconnection of IntServ and Di Serv networks for guaranteed services using a bandwidth management agent called BMP (Bandwidth Management Point).
