Slide3: 

Scientific Towns in Moscow Region 28 out of 73 ST’s in Russia

Slide4: 

Integration of IS and Resources: integration of the ST’s IS accelerated access to IS of ST’s search on the subspace of ST’s index file exchange piloting new technologies Main goals

Slide5: 

Connectivity and ISP variety: M9-IX Frankfurt-Teleglobe (Rostelecom) M9-IX - regions (Kaluga, …) about 27 ISP’s at 17 ST’s poor connectivity even within ST Main problems - 1. Connectivity

Slide6: 

Departmental variety: Russian Academy of Sciences Universities (national, regional, …) Ministeries Private R&D companies Main problems - 2. Organization Difficulties

Slide7: 

Architecture of the Distributed Depository of e-Documents: one multi-functional server at each ST exchange via cache-mesh (DDeD) Squid Web-Proxy Cache, www.squid-cache.org tested under grant RFBR 98-07-90293 and grant NSKT-NVSh 5.1.1 parent cache at SMBN (YuMOS) NOC Solutions - 1. Cache-mesh technology.

Slide8: 

Cache-mesh Technical Details: connectivity dBase (hop #’s, RTT values) connectivity dBase exchange dynamical optimization of the route easy to configure hierarchy document retrieval speedup cache-mesh route & IP routing table Solutions - 2. Cache-mesh technology.

Slide9: 

Search Troubles: www.google.com.ru «IPv6» - 984 000 references «IPv6 Linux» - 183 000 refs «IPv6 IPv4» - 169 000 refs «IPv6 gateway» - 55 900 refs «IPv6 Linux gateway» - 22 000 refs «IPv6 gateway LAN» - 22 000 refs Main Problem - 3. Information Flood and Garbage.

Slide10: 

Gathering and Indexing: gathering on the web-space of ST’s file indexing exchange of file indexes between servers query to local server usage of Metadata (http://dublincore.org) Solutions - 3. Harvest & Dublin Metacode.

Slide11: 

Harvest technology: Harvest (http://harvest.sourceforge.net) FreeBSD & Linux tested by IRiD - RFBR grant 01-07-90395 and PhysNet - EPS sponsored project Solutions - 4. Harvest & Dublin Metacode.

Slide12: 

Solutions - 5. Harvest, cache-mesh & IPv6.

Slide13: 

Intra-IPv6 and Outer-IPv4: queries: both protocols (IPv4 and IPv6) connecting old and new technologies some kind of information gateway Solutions - 6. Intra-server IPv6 network.

Slide14: 

Server functions 3in1: member of Cache-mesh Harvest technology IPv6 exchange Highlights - 1. New technologies.

Slide15: 

Information System highlights: dynamic (not static) auto-gathering (without human factors) fresh information (nightly or weekend updated) fast document retrieval (index+cache) distributed (decentralized) Highlights - 2. New technologies.
