FDDI (Fiber Distributed Data Interface) Ne \u0130\u015fe Yarar?<\/span><\/h2>\n

1980’lerin sonlar\u0131nda geli\u015ftirilen FDDI protokol\u00fc, b\u00fcy\u00fck kamp\u00fcs alan a\u011flar\u0131 (CAN) ve metropol alan a\u011flar\u0131 i\u00e7in iyi bir se\u00e7enekti. 100 Mbps’lik nispeten y\u00fcksek diyebilece\u011fimiz h\u0131z\u0131, standart Ethernet i\u00e7in \u00f6ng\u00f6r\u00fclen 10 Mbps’den \u00e7ok daha iyiydi. Ayr\u0131ca FDDI\u2019y\u0131 tek bir sunucu odas\u0131na ba\u011flay\u0131p di\u011fer sunucular\u0131 da buraya ba\u011flayarak ortak bir omurga olu\u015fturabiliyordunuz.<\/span><\/p>\n

FDDI-II ise ses ve video sinyallerinin de i\u015flenebilmesi i\u00e7in bir a\u011fa devre anahtarlamal\u0131 hizmet sa\u011flama yetene\u011fi ekleyen geli\u015ftirilmi\u015f bir FDDI s\u00fcr\u00fcm\u00fcyd\u00fc. FDDI a\u011flar\u0131n\u0131n, kiral\u0131k fiber optik hatlar olarak sunulan geli\u015ftirilme a\u015famas\u0131ndaki Senkron Optik A\u011flara ba\u011flanmas\u0131 i\u00e7inse \u00e7al\u0131\u015fmalar\u0131n devam etti\u011fini biliyoruz.<\/span><\/p>\n

FDDI protokol\u00fcn\u00fcn avantajlar\u0131n\u0131 200 kilometreye kadar ve net zamanlanm\u0131\u015f olarak veri aktar\u0131m\u0131 sa\u011flayabilmesi olarak \u00f6zetleyebiliriz. \u00d6te yandan eski bir protokol yap\u0131s\u0131 kullanmas\u0131, fazla maliyet gerektiren ekipmanlar\u0131 ve yeni protokollere g\u00f6re yava\u015f kalmas\u0131 gibi dezavantajlar\u0131n\u0131 saymak gerekir.<\/span><\/p>\n

G\u00fcn\u00fcm\u00fczde FDDI\u2019\u0131n yava\u015fl\u0131k ve maliyet \u00f6zelindeki dezavantajlar\u0131 y\u00fcz\u00fcnden yerini daha yeni Multi Gigabit Ethernet\u2019e ve pasif optik a\u011flara b\u0131rakt\u0131\u011f\u0131n\u0131 g\u00f6r\u00fcyoruz.\u00a0\u00a0\u00a0<\/span><\/p>\n

FDDI (Fiber Distributed Data Interface) \u00d6zellikleri<\/span><\/h2>\n

Bir FDDI a\u011f\u0131 iki token halkas\u0131 i\u00e7erir: Bir adet birincil halka ve olas\u0131 sorunlara kar\u015f\u0131 yedek olarak kullan\u0131lan ikincil bir halka. Birincil halka saniyede 100 megabite (Mbps) kadar kapasite sunarken, ikincil halka da veri ta\u015f\u0131mak i\u00e7in kullan\u0131labilir ve kapasiteyi 200 Mbps’ye de\u011fin y\u00fckseltir.\u00a0<\/span><\/p>\n

Bir halka saat y\u00f6n\u00fcnde, di\u011feri ise saat y\u00f6n\u00fcn\u00fcn tersine \u00e7al\u0131\u015facakt\u0131r. Tekli bir halka maksimum mesafeyi 200 kilometreye kadar uzatabilir; \u00e7ift yap\u0131da bir halkaysa 100 km\u2019ye kadar uzayabilir. Her hal\u00fckarda binlerce cihaz\u0131 tek bir FDDI a\u011f\u0131na ba\u011flayabilirsiniz.<\/span><\/p>\n

FDDI topolojisi standart halinde bir token halka a\u011f\u0131 olmas\u0131na ra\u011fmen, kullan\u0131c\u0131lar olarak bu yap\u0131y\u0131 bir y\u0131ld\u0131z topoloji d\u00fczenine de uygulayabilirsiniz. FDDI protokol\u00fcn\u00fcn Elektrik ve Elektronik M\u00fchendisleri Enstit\u00fcs\u00fc 802.4 say\u0131l\u0131 veriyolu zamanlanm\u0131\u015f jeton protokol\u00fcnden t\u00fcretildi\u011fini de not d\u00fc\u015felim.<\/span><\/p>\n

Token \u00fczerine temellendirilmi\u015f bir a\u011fda, yaln\u0131zca token\u2019i olan cihaz aktar\u0131ma kat\u0131labilir. Zamanlanm\u0131\u015f bir token\u2019in kullan\u0131lmas\u0131, her cihaz\u0131n veri iletebilmesi i\u00e7in gerekebilecek maksimum bekleme s\u00fcresini sa\u011flamay\u0131 garanti eder.\u00a0<\/span><\/p>\n

A\u011f gecikme gereksinimlerinize ba\u011fl\u0131 olarak, FDDI protokol\u00fcn\u00fc senkron veya asenkron bir yap\u0131da kurabilirsiniz. Senkronize yap\u0131lar gecikmeye duyarl\u0131 a\u011flar i\u00e7in uygundur ve zamanlan\u0131rlar. Asenkron d\u00fczen ise kat\u0131 \u015fekilde zamanlanm\u0131\u015f token\u2019ler kullanmaz.<\/span><\/p>\n

Tek modlu fiber optik kablo, FDDI’\u0131n birincil ara ba\u011flant\u0131 ortam\u0131d\u0131r. Burada bir parantez a\u00e7mam\u0131z gerekir zira fiber olmayan optik kablo kullanan FDDI standartlar\u0131 da mevcuttur: Bak\u0131r Da\u011f\u0131t\u0131ml\u0131 Veri Aray\u00fcz\u00fc, Twisted-Pair Fiziksel Ortama Ba\u011f\u0131ml\u0131 veya do\u011frudan Twisted-Pair Da\u011f\u0131t\u0131ml\u0131 Veri Aray\u00fczleri gibi.\u00a0<\/span><\/p>\n

Bir FDDI a\u011f\u0131nda, birincil y\u00f6nlendiricileri ve cihazlar\u0131 a\u011f\u0131n her iki halkas\u0131na da ba\u011flars\u0131n\u0131z. Bu d\u00fc\u011f\u00fcmlere ikili ba\u011flant\u0131 istasyonlar\u0131 denir. Ayr\u0131ca tek bir fiber optik ba\u011flant\u0131 arac\u0131l\u0131\u011f\u0131yla di\u011fer d\u00fc\u011f\u00fcmleri de birbirine ba\u011flayabilirsiniz ki bunlara tekli ba\u011flant\u0131 istasyonlar\u0131 denmektedir.\u00a0<\/span><\/p>\n

FDDI arac\u0131l\u0131\u011f\u0131yla di\u011fer protokolleri kullanan ba\u015fka a\u011f t\u00fcrlerine de ba\u011flanabilirsiniz. B\u00f6ylece daha b\u00fcy\u00fck bir Geni\u015f Alan A\u011f\u0131 (WAN) olu\u015fturabilir veya bir\u00e7ok farkl\u0131 istemciyi birbirine ba\u011flayabilirsiniz.<\/span><\/p>\n

\u00d6zetle FDDI, zaman\u0131nda devrim yaratan, \u00e7oklu zamanlanm\u0131\u015f ba\u011flant\u0131larla uzak mesafelere aksamadan hizmet sunabilen bir protokold\u00fcr. Hala da kamp\u00fcs a\u011flar\u0131nda ve baz\u0131 geni\u015f ortak alan a\u011flar\u0131nda kar\u015f\u0131m\u0131za \u00e7\u0131k\u0131yor ama protokoller ve ba\u011flant\u0131 teknolojileri geli\u015fip ucuzlad\u0131k\u00e7a yerini daha yeni alternatiflere b\u0131rak\u0131yor.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
