Cisco: sprzęt mobilny zatriumfuje
Dane Cisco pokazują, że od mobilności nie ma odwrotu. W roku 2018 po raz pierwszy w historii Internetu większość ruchu w sieci zarówno na świecie jak i w Polsce będzie pochodzić z innych urządzeń niż komputery. Przyspieszy rozwój Internetu Wszechrzeczy.

Według prognozy opublikowanej w Cisco Visual Networking Index do 2018 r. w Polsce liczba urządzeń połączonych z siecią wzrośnie do 178,4 mln, co oznacza średnio 4,7 urządzenia na jednego mieszkańca. W 2013 r. w sieci działało w naszym kraju 99,6 mln urządzeń (czyli do 2018 r. wzrost wyniesie 79 proc.). Za 4 lata komputery PC będą generowały 41 proc. ruchu w sieci IP (w 2013 r. było to 83 proc.), urządzenia przenośne, w tym smartfony i tablety – 43 proc., telewizory – 12 proc., zaś moduły M2M (Machine to Machine) – 3 proc. Wynika z tego, że w najbliższych latach utrzyma się duży popyt na sprzęt mobilny, częściej będą kupowane telewizory z dostępem do Internetu.
Zanosi się także na inwestycje w infrastrukturę sieci – średnia przepustowość łącza szerokopasmowego poprawi się w Polsce 2,5-krotnie, z 15,1 Mb/s w 2013 r. do 37 Mb/s w 2018 r. Ruch w sieciach IP zwiększy się trzykrotnie, osiągając roczny wzrost na poziomie 23 proc., natomiast ruch tylko w sieciach mobilnych zwiększy się 10-krotnie (co roku 60 proc. na plusie) i będzie 4-krotnie szybszy niż w stacjonarnych sieciach IP w tym samym okresie. Znacznie zwiększy się transfer danych związany z usługami wideo – w 2018 r. będzie stanowił 65 proc. całego ruchu w sieci (w 2013 r. – 42 proc.).
Jeśli chodzi o prognozy dla świata, to w roku 2018 według Cisco przez sieci IP przesłanych zostanie więcej danych, niż we wszystkich ubiegłych latach łącznie. Dynamiki nabierze rozwój Internetu Wszechrzeczy. Do 2018 r. liczba modułów M2M (Machine to Machine) niemal zrówna się z liczbą ludzi na Ziemi.
Ruch w światowej sieci IP w latach 2013-2018 wzrośnie trzykrotnie, głównie dzięki większej liczbie użytkowników i urządzeń, przepustowości sieci oraz popularności treści wideo. Globalny roczny ruch w sieciach stacjonarnych i mobilnych w 2018 r. osiągnie 1,6 zettabajtów (1 zettabajt = bilion gigabajtów).
