Vazeni pratele,
omluvte nejprve nesplneni naseho drivejsiho slibu, ze
prineseme shrnujici informace o vysledcich INET'94. Puvodni zamer
se nam sice nepodarilo uskutecnit, ale diky poradatelum a kolegum
z UK nejdulezitejsi materialy jsou k dispozici na cesnetovskych
serverech (viz Omicron News, 1/94). Toto cislo obcasniku
OMICRON-ECHO je venovano kratke informaci o dalsich osudech nam
velmi zname site NSFNET a pripomenuti sberu informacnich "sperku"
na gopherskych serverech v Internetu. S timto cislem prijmete
prosim prani vseho nejlepsiho v roce 1995, hlavne pevneho zdravi,
mnoha uspechu a spokojenosti.

1. JAKY BUDE DALSI OSUD SITE NSFNET ?
Vladimir Vrabec, OMICRON
Jiste mnohym z nas je znamo, jakou ulohu sehrala sit NSFNET
v rozvoji Internetu. Pripomenme si zakladni fakta:
- NSF (National Science Foundation) propojuje v roce 1986 pet
superpocitacovych stredisek infrastrukturou s paterni rychlosti
56 Kbps
- v roce 1987 poveruje NSF konzorcium michiganskych univerzit,
Merit Network, Inc., petiletou spravou paterni site NSFNET;
spravy se ucastni i IBM a MCI
- Merit, IBM a MCI vytvareji pozdeji Advenced Network & Services,
Inc. (ANS), zabyvajici se komercnim prenosem pres paterni
infrastrukturu
- v roce 1989 NSFNET prechazi na paterni rychlost 1.5 Mbps (T1)
- v roce 1992 NSFNET prechazi na paterni rychlost 45 Mbps (T3)
- v roce 1993 je vytvorena domena "internic.net" poskytujici
adresarove a databazove sluzby (AT&T), registracni servis
(Network Solutions,Inc.) a informacni sluzby (General Atomics,
CERFNet)
- letos byl zverejnen dalsi plan rozvoje architektury site NSFNET
Nova architektura site NSFNET vychazi z toho, ze puvodni
urceni teto site jako vyzkumne site preslo do stadia provozni
site a pro budoucnost je ucelne, aby tato jeji funkce byla
realizovana na komecnim zaklade prostrednictvim NSPs (Network
Sevice Providers). NSF se v souladu se svou pusobnosti soustredi
na zabezpecovani dalsiho rozvoje spickovych sitovych technologii
prostrednictvim projektu VBNS (Very high-speed Backbone Network
Service), zahrnujiciho NAPs (Network Access Points) s RA (Routing
Arbiter).
Sit VBNS bude dimenzovana pro propojeni peti
superpocitacovych stredisek. Vyvoj a provoz teto site byl sveren
firme MCI. NAPs jsou brany mezi VBNS a ostatnim Internetem. Budou
vybaveny sluzbou RA, ktera bude poskytovat sitim pripojenym na
NAPs routovaci informace, informace o topologii, vnitrnim
propojeni a pod. Vyvoj a udrzbu RA bude zajistovat Merit ve
spolupraci s institutem jihokalifornske univerzity ISI
(Information Science Institute). NAPs pripravi firmy Bellcore
(Chicago a Palo Alto), MFS Datanet (Washington) a Sprint (New
York). Schema teto nove architektury je uvedeno na obrazku 1.

OBRAZEK 1
Po dobu ctyrleteho prechodoveho obdobi bude NSF utlumove
spolufinancovat cinnost soukromych NSPs, schopnych prevzit
funkce, ktere provozne zabezpecovala paterni infrastruktura
NSFNET pro regionalni a dalsi site.

2. GOPHERJEWELS
Vladimir Vrabec, OMICRON
Projekt Davida Rigginse GOPHERJEWELS je specifickym pokusem
predmetne katalogizovat stromovym zpusobem obsah gopherskych
serveru v Internetu. Realizovany system predevsim nabizi:
- pres 2000 stromove organizovanych smerniku na gopherske prvky
- vyhledavani pomoci JUGHEADu ve vsech menu systemu
- skupinu napovednich dokumentu pro gopherskou problematiku
- archivy e-konferenci pro GOPHERJEWELS a waisovske vyhledavani v
nich (gopherjewels, gopherjewels-talk).
