Presented under the auspices of the Special Focus on Next Generation Networks Technologies and Applications.

In this workshop we aim to identify the fundamental problems
to provide QoS in the IP networks, both from theoretical and application
oriented points of view.

The explosive growth of the Internet is accompanied by two
paradigms. First, the IP-based networking is expected to be the
dominant infrastructure. Second, unconventional applications such as IP
telephony, Virtual Private Networking, Real-time transactions, IP HDTV,
are expected to be carried on the IP-based networks.  
These two paradigms are translated to the following challenge: how to
provide Quality of Service (QoS) in the IP-based
Internet.  Fundamentally the IP-based networking is designed for
delivering data traffic with best-effort (i.e., no guarantee) service,
thus it is not capable of providing end-to-end QoS.  The challenge is
to devise new protocols and algorithms  for providing QoS while maintaining
the basic principles of IP-based networking. 


This workshop will include, but will not be limited to the following topics.

A.  Overview: QoS on IP networks, both wired and wireless.
    Emerging high-speed technologies of QoS
    IP over ATM, IP over SONET, etc.
    What is QoS? Requirements, resources, allocation/protection of 
    the resources.
B.  Current state of the field.  
    1.  Diffserv
    2.  Intserv
    3.  MPLS   

C.  Quality of Service in Wireless IP Networks.

D.  QoS Routing, provisioning, pricing.

E.  Packet Filtering/Classification.

F.  QoS Resource Reservations/Signaling (RSVP, LDP, ...).

G.  Packet Scheduling to improve performance, as well as to 
    satisfy QoS guarantees.

H.  Related issues such as congestion control, multicast, network
    optimization, etc.
