IP as Ultimate Internetworking Glue IP over Everything Everything over IP Hourglass vs Winegl

Where We Are (II) Ethernet as Winning Link Technology
Ethernet Everywhere WLAN = Wireless Ethernet?
IP + Ethernet for Data Not perfect for QoS Streams(Voice, Audio, V
ideo) Just right for non-QoS(quasi-QoS or CoS) QoS possible for a few sessions

Lesson: Keep it Simple and Stupid
Simple is the best Internet vs OSI Ethernet vs ATM
End-to-End Argument Keep network simple/stupid and Put Intelligence at edges/ends Don’t build in the core anything that can be
built at edges/ends

Lesson: Flexible vs Conservative
Protocol Be flexible in what you receive Be conservative in what you send Example: TCP
Network Be flexible in what you adopt Be conservative in what you abandon Examples: Magnetic, Modem, Copper, ... Future examples: Ethernet, IP, ATM, ...

Lessons: More
Convergence Data + Voice Wired + Wireless Dream Not Come True?
Extremely difficult to put new functions/features in the Infra
Layer independence Need new assessment

What’s Next? Internetworking issue over: IP Applications, Services!
Middleware, Web Services, GRID, … Wireless: Just last hop
Mobility, Security, QoS Physical, Medium; Still evolving Long way yet to the Netopia? We’re in the low tide.

Issues Yet Pending
QoS Multicast; Group Communications Mobility Security Which layer?
Not IP? Link? Application? Wireless
03-08-23 11dykim@{cnu.ac.kr; anf.ne.kr}
QoS(I) Different Ideas about QoS
Security, Static BW, Rigorous Definition of QoS
Reliability Throughput
Dynamic thru Quasi-dynamic Delay, (Delay) Jitter
03-08-23 12dykim@{cnu.ac.kr; anf.ne.kr}
QoS(II)
Back to the Basics/Principles(KISS) Circuit for QoS Packet for Data Don't mix up
Circuit over Packet? ATM, PWE, etc., …
Packet over Circuit!

Circuit over Packet
QoS(III)
03-08-23 14dykim@{cnu.ac.kr; anf.ne.kr}
And More Multicast
Not at the IP layer? At the Application Layer?
Overlay Multicast, CDN At the Link or Physical Layer?
Mobility Fast enough? Where?
Security Mature? Convenient?

Third Wave of the Internet The first wave - text and data services such as e-mail and FTP
The second wave - the web which improved ease of use and facilitated the transfer of images, sound and video
The third wave - integration of grids - p2p networking - open source - distributed computing enabled by next generation web services, semantic web and high speed networks
