  2. Jini Scaleability 1 of 2 Intelligent … Sandboxes Interconnector Dynamics Scale …... Network@Jini.RMI Jini + EnvironmentalAwareness = IQhigh Networking ……….. Configuration is Pain Sandbox.A... Time + Space + Volume ... Sandbox.B 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 SLP IIOP ? Network Transport ? “UMTS” http://n.ethz.ch/student/rkurmann/UC/ubi_spontan_foils/img1.htm

  6. Scalability: Jini Discovery Scalability is Intelligence.Bundle {Time, Space/Volume} Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  7. Proprietary.Protocol@Consumer.Net? Private Protocols OneWayRoad Tactics Isolation Scalabe ? Tactical Solutions Might Scale Poorly {Time, Space} e.g. IBM SNA*, NetBIOS, IPX/SPX, DECnet pls. consult OSI Poster *from IBM(1980 - 1999) globally disappearing, Non-Routable Layer 2 Polling! Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  8. 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/

  13. Net.Appliances „Sandboxes <> 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 NOT intrinsically Secure (and therefore Scalable) Denial of Service Policies ...outside swimming pools watch for unnecessary unwanted grain/sand in the Desert.Core.Net

  14. Reality: Ultimate Jini Prospect (1 of 3) Lpt1 Converter to FullDuplex 100BaseTX The Ultimate Jini Prospect: 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/

  15. No Collision 1000BaseFX (2 of 3) Merry Christmas, and … Multi Gigabit Trunking to support (n x m) spontaneousness Intelligent ISP with Jini/JVM on top of SNMP ….… probably “K-Tip and Beobachter” to reduce the January invoice from provider December 22, 2000 One Single Talker, no Respose to tcp/Acknowledment Seminar 37-331 Information & Kommunikation WS 2000/1 http://www.tik.ee.ethz.ch/~huang/teach/

  16. 100BaseTX Fdx Benchmark (3 of 3) Scalability and Jini strong commitments from RMI/Jini Communities towards Network_Scalability missing. Infrastructure is not the primary concern… Capacity planning is ONE challenge with high impact dynamic services placement. Tuning and support another opportunity for scalable implementations; spontaneously federating sandbox Backtracking your telefon bill is another work item… Layer 5 and higher focused engineers could skip the following Sniffer detail charts….
