Packet Loss Nedir?<\/h2>\n

Packet loss kavram\u0131n\u0131 a\u00e7\u0131klayabilmek \u00f6ncelikle \u201cpacket\u201d kavram\u0131na bakmak gerekir. Bu da asl\u0131nda internetin nas\u0131l \u00e7al\u0131\u015ft\u0131\u011f\u0131 ile ilgili bir kavramd\u0131r. \u0130nternet trafi\u011fi i\u00e7erisinde t\u00fcm a\u011flar bir\u00e7ok veri ta\u015f\u0131r. Bu veri birimlerine de packet yani paket ad\u0131 verilir. Biraz daha detayland\u0131rmak gerekirse, internet a\u011flar\u0131 verileri b\u00f6lerek ta\u015f\u0131r. Bu b\u00f6lme i\u015fleminden sonra da ortaya paketler ortaya \u00e7\u0131kar. Packet loss internet performans<\/a> \u00f6l\u00e7\u00fctlerinden birisidir.<\/p>\n

Packet loss yani paket kayb\u0131 en basit ifade bi\u00e7imiyle bir a\u011f ortam\u0131nda ge\u00e7en paketlerin hedeflerine ula\u015fmadan \u00f6nce \u2018\u2019\u00e7al\u0131nmalar\u0131\u2019\u2019 durumudur. Packet loss durumunun birka\u00e7 nedeni vard\u0131r.<\/p>\n

Bu nedenler \u015f\u00f6yle s\u0131ralanabilir:<\/p>\n

Ba\u011flant\u0131 S\u0131k\u0131\u015f\u0131kl\u0131\u011f\u0131<\/h2>\n

\u2018Packet loss\u2019un ba\u015fl\u0131ca nedenlerinden biri, ba\u011flant\u0131 t\u0131kan\u0131kl\u0131\u011f\u0131d\u0131r. Basit bir benzetme yaparsak, yolda yeteri kadar yol alabilece\u011finden daha fazla araba oldu\u011funda trafikte saatin yo\u011funla\u015fmas\u0131 durumudur. Ya da 4 \u015feritli bir yolun ileride 2 \u015feride d\u00fc\u015fmesi durumunda ya\u015fanan s\u0131k\u0131\u015f\u0131kl\u0131\u011fa benzetilebilir. Olan \u015fey \u015fu ki, bir linke i\u015flemek i\u00e7in tasarlanandan daha fazla paket geldi\u011finde bir yava\u015flama s\u00f6z konusu olur.<\/p>\n

Baz\u0131 durumlarda, ba\u011flant\u0131 teknik olarak ula\u015fan trafik miktar\u0131n\u0131 teknik olarak idare edebilse dahi, belirli bir s\u0131n\u0131r\u0131n ard\u0131ndan paketleri b\u0131rakmak \u00fczere yap\u0131land\u0131r\u0131lm\u0131\u015ft\u0131r.<\/p>\n

Ba\u011flant\u0131 teknik olarak 1000 Mbps<\/a>‘ye kadar desteklese bile, ISS kurumlar\u0131n\u0131 sadece 2 Mbps’lik trafi\u011fe zorlayabilmesi i\u00e7in cihazlar\u0131n\u0131 yap\u0131land\u0131racakt\u0131r. Daha fazlas\u0131 genellikle b\u0131rak\u0131lacakt\u0131r.<\/p>\n

A\u011f t\u0131kan\u0131kl\u0131\u011f\u0131n\u0131n bir ba\u015fka \u00f6rne\u011fi de servis sa\u011flay\u0131c\u0131lar\u0131n bilerek bir aboneli\u011fi abonelikten \u00e7\u0131karmalar\u0131d\u0131r. Bunun sebebi, bu hizmetin t\u00fcm abonelerinin ba\u011flant\u0131y\u0131 ayn\u0131 anda kullanmayacak olmalar\u0131d\u0131r. Bununla birlikte, hizmeti yo\u011funlu\u011fundan daha fazla insan\u0131n kulland\u0131\u011f\u0131 kapasiteden daha fazla kullanan ki\u015fi, t\u0131kan\u0131kl\u0131ktan kaynaklanan packet loss sorunuyla kar\u015f\u0131la\u015f\u0131r.<\/p>\n

A\u015f\u0131r\u0131 Kullan\u0131lm\u0131\u015f Cihazlar<\/h2>\n

A\u011f t\u0131kan\u0131kl\u0131\u011f\u0131na benzer packet loss’un bir ba\u015fka nedeni de a\u015f\u0131r\u0131 kullan\u0131lan cihazlard\u0131r. Bu, bir cihaz\u0131n tasarlanmad\u0131\u011f\u0131 kapasitede \u00e7al\u0131\u015ft\u0131\u011f\u0131 anlam\u0131na gelir. Bir a\u011fda, paketler i\u015flendiklerinden daha h\u0131zl\u0131 ula\u015fabilirler.<\/p>\n

Bu t\u00fcr bir durumla ba\u015fa \u00e7\u0131kmak i\u00e7in, bir\u00e7ok cihaz\u0131n i\u015flenip g\u00f6nderilinceye kadar ge\u00e7ici olarak paketleri tuttuklar\u0131 ara bellekleri vard\u0131r. Bununla birlikte, a\u015f\u0131r\u0131 kullan\u0131lan bir cihaz durumunda, tampon muhtemelen h\u0131zl\u0131 bir \u015fekilde dolar ve fazla paketlerin d\u00fc\u015fmesine neden olur.<\/p>\n

\u00c7o\u011fu zaman olan, cihaz\u0131n normal (yo\u011fun olmayan) \u00e7al\u0131\u015fma s\u00fcreleri boyunca yeterince iyi bir performans g\u00f6stermesidir ancak yo\u011fun d\u00f6nemlerde, genellikle cihaz\u0131n y\u00fcksek CPU kullan\u0131m\u0131nda belirgin olan performansta g\u00f6zle g\u00f6r\u00fcl\u00fcr bir d\u00fc\u015f\u00fc\u015f olacakt\u0131r.<\/p>\n

Hatal\u0131 Donan\u0131m veya Yaz\u0131l\u0131m<\/h2>\n

Packet loss’un bir ba\u015fka nedeni de hatal\u0131 donan\u0131md\u0131r. Bu, bir cihaz\u0131n bir bile\u015feni veya cihaz\u0131n kendisi olabilir.<\/p>\n

Baz\u0131 durumlarda ba\u011flant\u0131 ba\u015fka bir aray\u00fcze ta\u015f\u0131nd\u0131\u011f\u0131nda performans art\u0131\u015f\u0131 g\u00f6zlemlenebilir.<\/p>\n

Geli\u015ftirme ekibinin a\u011f ayg\u0131tlar\u0131nda \u00e7al\u0131\u015fan yaz\u0131l\u0131mdaki t\u00fcm hatalar\u0131 yakalamas\u0131 genellikle imkans\u0131zd\u0131r ve bu hatalardan biri packet loss’a neden olabilir.<\/p>\n

Kablolu ve Kablosuz A\u011flar<\/h2>\n

A\u011f ortam\u0131 t\u00fcr\u00fc ayr\u0131ca packet loss’un bir nedeni olabilir. Genel olarak konu\u015fursak, wireless (kablosuz a\u011f) kullananlar, kablolu a\u011f kullanan meslekta\u015flar\u0131ndan daha fazla aksamalara maruz kalabiliyor. \u00d6rne\u011fin, radyo frekans\u0131 paraziti, kablosuz a\u011flarda packet loss’a neden olan \u00f6nemli bir sorun olabilir.<\/p>\n

Kablosuz bir a\u011fda packet loss’a neden olabilecek di\u011fer zorluklar aras\u0131nda zay\u0131f sinyal, mesafe s\u0131n\u0131rlamalar\u0131 ve (yanl\u0131\u015f yap\u0131land\u0131r\u0131lm\u0131\u015f) dola\u015f\u0131m vard\u0131r; bunlar\u0131n \u00e7o\u011fu wifi analiz\u00f6r\u00fcn\u00fcn bir kombinasyonu ile \u00e7\u00f6z\u00fclebilir.<\/p>\n

Kablolu a\u011flarda, hatal\u0131 kablolar packet loss’a neden olabilir. Bu, kablonun uygun \u015fekilde sonland\u0131r\u0131lmamas\u0131 veya kablonun hasar g\u00f6rmesi nedeniyle kablodan akacak elektrik sinyali i\u00e7in sorunlara neden olabilir.<\/p>\n

Sald\u0131r\u0131<\/h2>\n

Bir cihaz sald\u0131r\u0131 trafi\u011fiyle bo\u011fulmu\u015f oldu\u011funda\u00a0 me\u015fru paketlerin d\u00fc\u015fmesine neden olabilir. Bu da yine packet loss’a sebep olur.<\/p>\n

Hatal\u0131 Yap\u0131land\u0131rma<\/h2>\n

Packet loosa son sebep olan neden de hatal\u0131 konfig\u00fcrasyondur. Yani, bir ba\u011flant\u0131daki iki cihaz aras\u0131ndaki h\u0131z ve \u00e7ift y\u00f6nl\u00fc uyumsuzluktur. Bir cihaz yar\u0131 \u00e7ift y\u00f6nl\u00fc i\u00e7in yap\u0131land\u0131r\u0131lm\u0131\u015f, di\u011feri tam \u00e7ift y\u00f6nl\u00fc i\u00e7in yap\u0131land\u0131r\u0131lm\u0131\u015fsa, muhtemelen ba\u011flant\u0131da packet loss ile sonu\u00e7lanacak \u00e7arp\u0131\u015fma olacakt\u0131r.<\/p>\n

Not: <\/strong>Her a\u011f zaman zaman packet loss gibi sorunlarla kar\u015f\u0131la\u015f\u0131r. Bu beklenen bir \u015feydir. Ancak, bu sorunlar\u0131n a\u011f\u0131n performans\u0131 \u00fczerinde olumsuz bir etkisi olmamas\u0131 gerekir.<\/p>\n","protected":false},"excerpt":{"rendered":"
