Abstract:
This paper presents an overview of Internet QoS, covering
motivation and considerations for adding QoS to Internet,
the definition of Internet QoS, traffic and service specifi-
cations, IntServ and DiffServ frameworks, data path operations
including packet classification, shaping and policing,
basic router mechanisms for supporting QoS, including
queue management and scheduling, control path mechanisms
such as admission control, policy control and bandwidth
brokers, the merging of routing and QoS, traffic engineering,
constraint-based routing and multiprotocol label
switching (MPLS), as well as end host support for QoS.We
identify some important design principles and open issues
for Internet QoS.
