Abstract * Foil Index for this file
We discuss the Global Information Infrastructure (GII) as a set of several million clients (Set-Top boxes/PC's) linked by ATM networks to perhaps some ten thousand supercomputer class HPCC servers. This Infrastructure will support a set of base information services: |
InfoVision or Information(text), Video, Imagery, and Simulation ON Demand. It is reasonably clear what we need to implement this and we describe how base HPCC technologies can be used in InfoVision. |
InfoVision services can be used in defense (called Command and Control historically), Society and Business. We discuss our virtual corporation InfoMall and its early application testbeds with special attention to the Living Textbook where 6 schools are connected by high speed ATM networks to HPCC servers at NPAC. Here InfoVision services under development include video news clips browsed by a text database, images, HPCC environmental simulations and a 3D terrain navigation system with multimedia data arranged over New York State. Another basic service is that of a both automatic and teacher controlled cache of information from the internet. |

We discuss the Global Information Infrastructure (GII) as a set of several million clients (Set-Top boxes/PC's) linked by ATM networks to perhaps some ten thousand supercomputer class HPCC servers. This Infrastructure will support a set of base information services: |
InfoVision or Information(text), Video, Imagery, and Simulation ON Demand. It is reasonably clear what we need to implement this and we describe how base HPCC technologies can be used in InfoVision. |
InfoVision services can be used in defense (called Command and Control historically), Society and Business. We discuss our virtual corporation InfoMall and its early application testbeds with special attention to the Living Textbook where 6 schools are connected by high speed ATM networks to HPCC servers at NPAC. Here InfoVision services under development include video news clips browsed by a text database, images, HPCC environmental simulations and a 3D terrain navigation system with multimedia data arranged over New York State. Another basic service is that of a both automatic and teacher controlled cache of information from the internet. |

Key Features of InfoMall
|
Infrastructure
|
FLAG is an enterprise in which NYNEX Network Systems Company is a major (roughly 40%) investor. |
Current fiber link from U.K. to Japan (via Africa) is being constructed at a $1.4B cost |
InfoMall is proposed as USA distributor of Information services to Africa
|
Current Contacts and potential InfoMall tenants are:
|
These will typically lease 64Kbit lines from NYNEX and FLAG to run from FLAG offramp in Africa to NPAC |
NPAC will supply technology to link Web Server at NPAC to Web Servers in Africa
|
Web Servers use "Web Technology" to service World Wide Web and other forms of networked multimedia information |
Hypothesis: Multimedia Information with real time video will be very important and require a megabit/second bandwidth or more per client |
The total national network bandwidth needed is minimized if server is near to the client |
It is least expensive to install local rather national or state high speed links |
Deduction: We have familiar "Data Locality" problem of Parallel Computing |
Hypothesis: It is possible to define "communities" so that most material accessed by many (in particular more than one) people. |
Data replication in hierarchical fashion is known solution with "pre-fetching", "caching" and "cache coherence" as issues |
Today's Explosion of use of the Internet stems from two developments
|
World Wide Web Project at CERN 1989
|
NCSA Mosaic 1993
|
Commercial Web Products
|
Why was WWW/Mosaic so succesful so quickly ?
|
Where will WWW/Mosaic go next ?
|
Why is WWW/Mosaic relevant for everybody?
|
Servers at NPAC will fetch data from internet (GII) and store on local disks
|
Example from Kids Web:
|
Base this on extrapolation from Kids Web Caching Experiments |
Compare with Encyclopedia Britannica === EB Below |
4600 of registered WWW Servers. (Maybe half of all servers in existence) |
Total Space about one terabyte = 1500 CDROM's |
Text Space : 185 Million Pages or 685 times text in EB |
Image Space: 5 Million Pictures or 317 times images in EB |
Movie space : 280 hours of small MPEG compressed material ( not in EB) |
Use of space in WWW servers: |
20% text, 60% Images, 3% Video, 17% other or unclear
|
All of 1992 : 0.5 Million pages |
January to March 1993: 5 Million pages |
May 1,1994 : 10 Million pages |
September 1,1994 : 50 Million pages |
Current Increase is 1% per day |
Unit is Page of Text or Equivalent (in Size) |
Note One page is about a kilobyte |
Using Log files produced by Mosaic, you can estimate number of individuals accessing material
|
KIdsweb is over half of all NPAC WWW accesses |
All the News and Sports Archives of Reuters correspond to about 25,000 hours of information
|
Estimate similar storage needs for:
|
Total storage about 100 terabytes today |
Focus Areas |

Partnership with Corporations including
|
Education and Training
|
Consulting with Corporations who are worried about how to integrate
|
In general these testbeds provide demonstrations and development environments for InfoMall products and services |
Three Related Education Experimental Projects
|
Motivation: NII will evolve to link schools, homes, offices, hospitals, government agencies with high speed digital links supporting real-time video for interactive collaboration and data access |
K-12 schools lack adequate technology infrastructure and currently there is little understanding if and how NII can be used in education |
So far use of technology in education has had modest success |
Internet provides exemplar of broad capabilities of NII |
NYNET with its MPP servers provides prototype of NII technologies |
Involve professionals in Newhouse School of Public Communication and Syracuse School of Education |

|
Several Research Applications including
|
Several Interesting new Computer Science technologies are needed to support this. We are developing PERL based Mosaic Server enhancements to support authoring of hyperlinked material.
|
These hyperlinked Interactive Multimedia approachs to Distance Learning can be extended to offer Degrees, Certicates, Courses etc. to remote users |
Each group of users would use their own focal Web server
|
Living Textbook is an example of this in K-12 Education |
SUNY HSC is juxtaposed to Syracuse University Campus and hopefully NYNET will extend from NPAC to SUNY HSC |

The World Wide Web is a network of computers connected via the Internet and communicating with a protocol that supports hypermedia. Some of these computers are (Web)Servers that provide Information that can be displayed by Browsers |
Browser is a user interface program for navigating and viewing Hypermedia. the Mailcap file determines which viewer may be used. There may also be interaction with other (Server) programs via the CGI. |
The Internet transmits MIME (MultiPurpose Internet Mail Exchange) data from the server. The Server responds to URL sent with HTTP by the Browser. If the MIME data is not HTML, the Browser may invoke a separate viewer. |
The Server is a program which responds to requests from Browsers for hypermedia. The URL supplied by the Browser determines if response is an HTML file or is to be generated by a CGI program. |

Open and Portable Document standards and Formats of importance include CORBA, OLE and ACROBAT |
Commercial communication and office automation technologies are in many ways far superior to those in WWW but: |
The Web technologies are open and have the huge and expanding Internet/NII marketplace. Thus they will set standards and define services which existing and new commercial software and hardware must be consistent with
