---

Dic 02, 199

1. Next Experiments
   • IBM testing to be completed, debugging for QoS measurement, new image with RED support
   • CISCO: debugging of traffic isolation and ATM shaping
   • Linux (work plan from Werner)
   • interoperability testing (Nortel, Torrent, Telebit and Lucent (?) could be added)
   • test of diffserv building blocks at high speed
2. EF Testing
   • EF: configuration tuning, queue size (?) and service rate of EF queue
   • Study of time properties (one-way delay and ipdv) in the WAN
   • study of EF aggregation effects on one-way delay and ipdv
   • ack colouring
   • WFQ vs Strict Priority Queueing
3. AF Testing:
   • WRED tuning
   • confiuguration and test of TCM (Three Colour Marker), rate-based and burst-lenght-based
4. Services
   • VLL and 1-nVLL validation
   • definition of new services based on AF
   • better than best effort
   • resource allocation on congested links (e.g. US lines)
5. Applications: test applications to be identified.
   Candidates:
   • voice over IP
   • video streaming
   • remote control
   • gaming (British Columbia Inst. of Technology, collaboration under evaluation)
6. Diffserv and MPLS (Jan/Feb 2000)
7. Diffserv and policy (Jan 2000)
8. Pilot services:
   • VLL, validation, test of interoperability between EF and ATM
