Network Switch Nedir?<\/strong><\/h3>\n

Network switch<\/strong>, veri paketlerini MAC adreslerine g\u00f6re y\u00f6nlendiren<\/strong> bir a\u011f cihaz\u0131d\u0131r. Gelen trafi\u011fi analiz ederek, verinin yaln\u0131zca hedef cihaza ula\u015fmas\u0131n\u0131 sa\u011flar. B\u00f6ylece gereksiz veri ak\u0131\u015f\u0131n\u0131 \u00f6nleyerek a\u011f trafi\u011fini d\u00fczenler.<\/p>\n

A\u011f i\u00e7inde daha verimli ve h\u0131zl\u0131 ileti\u015fim kurulmas\u0131n\u0131 sa\u011flamak i\u00e7in network switch<\/strong>, katman 2 (Data Link Layer) ve katman 3 (Network Layer) <\/strong>seviyelerinde \u00e7al\u0131\u015fabilir.<\/p>\n

Network Switch Nas\u0131l \u00c7al\u0131\u015f\u0131r?<\/strong><\/h3>\n

Network switch<\/strong>, ba\u011fl\u0131 oldu\u011fu a\u011f cihazlar\u0131n\u0131n MAC adreslerini \u00f6\u011frenerek<\/strong>, veri paketlerini en do\u011fru hedefe y\u00f6nlendirir. Bu s\u00fcre\u00e7 \u015fu \u015fekilde i\u015fler:<\/p>\n

    \n
  • Bir cihazdan veri paketi geldi\u011finde, switch<\/strong>, paketin kaynak ve hedef MAC adresini<\/strong> analiz eder.<\/li>\n
  • E\u011fer hedef MAC adresi<\/strong>, switch\u2019in adres tablosunda kay\u0131tl\u0131ysa, paket do\u011frudan ilgili cihaza y\u00f6nlendirilir.<\/li>\n
  • E\u011fer hedef MAC<\/strong> adresi<\/strong> bilinmiyorsa, switch<\/strong>, paketi t\u00fcm ba\u011flant\u0131 noktalar\u0131na (broadcast)<\/strong> g\u00f6nderir.<\/li>\n
  • Cihazlardan gelen tepkilere g\u00f6re, switch adres<\/strong> tablosunu g\u00fcncelleyerek veri y\u00f6nlendirme i\u015flemini optimize eder.<\/li>\n<\/ul>\n

    Bu y\u00f6ntem sayesinde a\u011f trafi\u011fi d\u00fczenlenir, veri \u00e7ak\u0131\u015fmalar\u0131 \u00f6nlenir<\/strong> ve ba\u011flant\u0131 h\u0131zlar\u0131 iyile\u015ftirilir<\/strong>.<\/p>\n

        \u2022Katman 2 ve Katman 3 Switch<\/strong><\/h3>\n
          \n
        • Katman 2 switch<\/strong>, MAC adresleri <\/strong>ile veri y\u00f6nlendirir ve a\u011f i\u00e7indeki cihazlar aras\u0131ndaki trafi\u011fi y\u00f6netir.<\/li>\n
        • Katman 3 switch<\/strong>, IP y\u00f6nlendirme <\/strong>yeteneklerine sahiptir ve router gibi \u00e7al\u0131\u015farak farkl\u0131 a\u011f segmentlerini birbirine ba\u011flayabilir.<\/li>\n<\/ul>\n
