  1. Towards Next Generation Yuji Oie Kyushu Institute of Technology Program Co-Chair of Saint 2003

  2. Key Features • Mobility, Ubiquity, Agility • Mobile Computing • Pervasive Computing • Agile Computing

  3. From a Viewpoint of Network Technology • Internet Traffic Engineering deals with the issue of • Performance evaluation • Performance optimization of IP networks • Encompasses a wide range of network technologies (e.g., draft-ietf-tewg-qos-routing-04.txt draft-ietf-tewg-principles-02.txt)

  4. What is the goal of TE? • The goal is to • Optimize network resources, while • Satisfying traffic oriented performance requirements

  5. Category based upon a time scale • Planning • Capacity planning • Designing • Routing design, Capacity design • Managing • routing policy, buffer management,bandwidth broker Long term (proactive) Shortterm (reactive)

  6. Key features • Diversity in • applications over IP • E-commerce, contents delivery with different requirements as well as conventional use • network technologies under IP • MPLS, WDM, mobile, wireless link • Rapidly changing requirements

  7. Applications and Internet:Example • Application aware TE • CDN (Contents Delivery Networks) is tuned up for a specific application

  8. Further solutions for other applications Explicit notification from different layersCollaboration among different layers Reactive and Proactive ways Based upon Estimation and Forecast

  9. Network Technologies Embracing Heterogeneity Let’s collaborate

  10. Join the workshop on measurement tomorrow
