M'makompyuta a pamsewu, nsana ya m'mbuyo ndi njira yaikulu yomwe imagwiritsidwa ntchito popititsa mauthenga a pa intaneti pamtunda. Kubwerera kumbuyo kumagwirizanitsa ma intaneti (LANs) ndi malo ambiri (WANs) pamodzi. Maseŵera obwerera kumbuyo apangidwa kuti apangitse kudalirika ndi ntchito ya maulendo akuluakulu, kutalika kwa deta. Malo odziwika bwino otetezedwa ndi intaneti ndi omwe amagwiritsidwa ntchito pa intaneti.
Internet Backbone Technology
Pafupifupi maulendo onse a pawebusaiti, kusanganikizana kwa kanema, ndi magalimoto ena amtundu wa intaneti akuyenda kudzera pa intaneti. Zimapangidwa ndi makina opangira mauthenga omwe amasungidwa makamaka ndi zipangizo za fiber optic (ngakhale zigawo zina za Ethernet pazitsulo zochepa zamtundu wa backbone ziliponso). Chida chilichonse chogwiritsidwa ntchito pamsana pake chimapereka 100 Gbps of network bandwidth . Makompyuta amalephera kulumikizana ndi msana. M'malo mwake, ma intaneti a operekera mautumiki a intaneti kapena mabungwe akulu amalumikizana ndi mabanki ameneŵa ndi makompyuta amatha kumbuyo msana.
Mu 1986, US National Science Foundation (NSF) inakhazikitsa mzere woyamba wa intaneti pa intaneti. Chiyanjano choyamba cha NSFNET chinaperekanso 56 Kbps - kuwonetseratu ntchito kumayesero lero - ngakhale kunakonzedwa mwamsanga ku 1.544 Mbps T1 mzere ndi 45 Mbps T3 ndi 1991. Mabungwe ambiri aphunziro ndi mabungwe ofufuzira anagwiritsa ntchito NSFNET,
M'zaka za m'ma 1990, kukula kwakukulu kwa intaneti kunkaperekedwa ndalama zambiri ndi makampani odzipangira okha omwe anamanga zipangizo zawo. Pambuyo pake intaneti inayamba kukhala ndi mabanki aang'ono omwe amagwiritsidwa ntchito ndi Internet Providers Providers omwe amapita kumayiko akuluakulu omwe ali ndi makampani akuluakulu osonkhanitsira mafoni.
Kubwerera kumbuyo ndi Kusonkhana
Njira imodzi yosamalira miyeso yapamwamba kwambiri ya deta yomwe imayenda kudzera pa network backbone imatchedwa link aggregation kapena trunking. Kulumikizana aggregation kumaphatikizapo kugwiritsidwa ntchito kovomerezeka kwamitundu yosiyanasiyana pamakina oyendetsa kapena kusintha kuti athandize dera limodzi la deta. Mwachitsanzo, maulendo anayi ogwirizana a ma Gbps omwe amathandiza nthawi zambiri mndandanda wa deta akhoza kusonkhanitsidwa palimodzi kuti apereke imodzi, 400 gbps. Olamulira a makina akukonzekera hardware pamapeto onse a kugwirizana kuti athandizire trunking iyi.
Nkhani ndi Network Backbones
Chifukwa cha ntchito yawo yaikulu pa intaneti ndi mauthenga apadziko lonse, kukhazikitsidwa kwa nsana za m'mbuyo ndilo cholinga chachikulu pa ziwonongeko zoopsa. Othandizira amakonda kusunga malo ndi zina zamakono za zobvala zawo zakubwera chifukwa chaichi. Kafukufuku wina wa yunivesiti pa intaneti ya nsana ya intaneti ku US, mwachitsanzo, adafuna zaka zinayi zafukufuku ndipo akadali osakwanira.
Nthaŵi zina maboma a dziko amayesetsa kulamulira mauthenga a m'mbuyo mwa dziko lawo ndipo akhoza kutsegula kapena kutsegula kwa intaneti anthu ake. Kuyanjana pakati pa mabungwe akuluakulu ndi malonjezano awo chifukwa chogawana makompyuta amakhalanso ndi zovuta zamalonda. Lingaliro la kusaloŵerera m'ndale kumadalira eni ake ndi osunga malo ogwiritsira ntchito nsana zamtunduwu kuti azitsatira malamulo a dziko lonse ndi mayiko ndi machitidwe ogulitsa bwino.
