  1. Agent Technology Scalability Consideration - January 2001 Christian Gloor & Hans-Peter Roetheli Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  2. Jini „Intelligent Agent Technology“ Jini ...... Java Intelligent Network Infrastructure .. „connection technology based on Java“ Network.IQ No Limits in Space Time.IQ No Performance Limitation Awareness.IQ Any Transport Protocol Jini.Services.A not low level logistics Jini.Services.B Jini.FedA Time + Space + VolumeAgent.B Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  3. Jini = „Java Infrastructure + Logistics“ No Waste of Time ! Priority Queues, Speed of Light How Far? Reach Mobility Flexibility Space How Much ? Volume Bandwith Burstiness Talkers • EndPointsSources Sinks • Intermediate Hops Broadcast Unicast (Multicast) • Links Protocols Shared or Dedicated (Non-)Blocking Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  4. Scalable Implementation Agenda Part A Jini RecapETH SS2000 WS2001 Part B: Layer 4+ Beyond Jini RMI JVM Part C: Layer 4- Below Transport Routing IP Part D: End 2 End JVM Industry Adoption Part E: Conclusion Readiness for Intelligent Agents Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  5. Consumer Orientation and Outside [3] Presented by Roland Kurmann ETHZ Fachseminar SS2000 Ubiquitous Computing Jini service discovery Spontane Vernetzung RMIsec + SLP + IIOP ? AnyNetwork Transport ? E.g. UMTS http://n.ethz.ch/student/rkurmann/UC/ubi_spontan_foils/img1.htm

  6. Proprietary.Protocol@Consumer.Home Private Protocols OneWayRoad Tactics Isolation ..Scalable ? Tactical Solutions Might Scale Poorly e.g. IBM SNA*, NetBIOS, IPX/SPX, DECnet *IBM(1980 - 1990) since 1995 disappearing. Not Routable. Layer 2 Polling Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  7. Hybrid {PKI - LUS} SLP Relay for LUS Standalone Cleverness and Scalablility IIOP RADIUS A,,,D IETF IP-stack Federations A,,,D Sooner or later, intelligent federations will require Interop = IP Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  12. Net.Appliances „coreBB“ “Just want to say Hello Friends” 3200 Packets/Second sustained Talk = opportunity for benchmarking scalable Link ISP Capacity Financial Muscle “Spontaneouseness might arrive at reasonable price tag ….in the future Jini 1.1 of Today seems neither intrinsically Secure nor Scalable” e.g. Denial of Service Attack watch for unnecessary unwanted Grain {sandboxes.interconnect}

  13. Where is Your Nearest „Hot Spot?“ Lpt1 Converter to Full Duplex 100BaseTX Ultimate Jini Prospect Service lpd-”proxy”-interface Scalability at 100Mbps “lpd/lpr over centronics” Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  14. No Collision 1000BaseFX? „No Filter“ Merry Christmas, and … Multi Gigabit Trunking to support distributed spontaneousness Need “Intelligent ISP” ….… “Kassensturz” or “Beobachter” to reduce January Invoice from ISPs / ASP Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/
