Abstract :
A new DiffServ per-hop behavior (PHB) reservation protocol (DPRP) is proposed to support the end-to-end QoS guarantee in a DiffServ network through several domains. It is a reservation mechanism that inherits the advantages of RSVP but is a lightweight version of RSVP. DPRP transports and negotiates the QoS requirement between sources and destinations as well as reserves PHB for service levels in each DS domain. It negotiates a dynamic service level agreement (SLA) between various domains efficiently and guarantees the end-to-end QoS of the DiffServ network. Essential principles and advantages of DPRP are presented
