ABroket Packet.Kuyeserera kwa intaneti (Dinani), ndi chipangizo cha hardware chomwe chili ndi chingwe cha pa intaneti ndikutumiza chidutswa cha kulumikizana ndi zida zina.
Osuntha patchket amagwiritsidwa ntchito poyerekeza ndi ma netiweki (ma ID), zoyang'ana pa intaneti, ndi abwana. Gawo la port. Munjira yovuta, ulalo woyang'aniridwa (ulalo wosazikika) wagawika magawo awiri ndi chipangizo chopunthwitsa. Chidziwitso chopsinjika chimalumikizidwa ndi mawonekedwe osonkhanitsa kuti atolere deta yazolowera ku intaneti.
Kodi pa intaneti packet (NPB) imakuchitirani chiyani?
Zofunikira:
1. Kudziyimira pawokha
Ndi gawo lodziyimira pawokha ndipo silimakhudzanso katundu wa zida za network, zomwe zimakhala ndi zabwino pa doko.
Ndi chida cha mzere, chomwe chimangotanthauza kuti chikufunika kukhala ndi intaneti. Komabe, izinso zimandikhudzanso kuti mukupereka gawo la kulephera, ndipo chifukwa ndi chipangizo cha pa intaneti, intaneti yomwe ikuyenera kusokonezedwa nthawi yowonjezera, kutengera komwe ikuperekedwa.
2. Zowonekera
Transparent amatanthauza cholembera pa intaneti yapano. Mukatha kupeza ma network, sizikukhudza zida zonse mu netiweki pano, ndipo imawonekeratu. Zachidziwikire, izi zimaphatikizaponso magalimoto omwe amatumizidwa ndi chipangizo chowunikira, chomwe chimawonekeranso ku netiweki.
Mfundo Yogwira Ntchito:
Masewera osokoneza bongo (olekanitsidwa) potengera deta yofikira, kusinthitsa, kusefa, kusinthidwa kwa ma protocol kusinthidwe, malinga ndi mapaketi onse a ma megabytes omwe amatulutsa ma picketor onse ogwiritsa ntchito.
Zogwira Ntchito:
1. Kutembenuka kwa Protocol
Makina olumikizirana a data internet Internet omwe amagwiritsidwa ntchito ndi ma isps amaphatikiza 40g pos, 10g pos / wan / lan, pomwe geni, pomwe deta italandira masentimita 10. Chifukwa chake, kutembenuka kwa protocol nthawi zambiri kumatchulidwa pa kulowerera kwa intaneti kumatanthauza kutembenuka pakati pa 40g pos, ndi 2.5g postens pakati pa 10ge Wan ndi 10Ge.
2. Kusonkhanitsa kwa data ndi kugawa.
Ntchito zambiri zosonkhanitsira zambiri zimatulutsa magalimoto omwe amasamala ndikutaya magalimoto omwe sawakonda. Magalimoto a data ya IP, protocol, ndi doko zimatengedwa ndi adilesi ip isanu (kopita ip, komwe mukupita, gwero la port, ndi protocol). Pakatulutsa, gwero limodzi, malo omwewo ndi katunduyo wotulutsa amawonetseredwa malinga ndi hash algorithm.

Kwa p2p pamsewu wa P2p, pulogalamu yogwiritsa ntchito imangoyang'ana pamsewu wina, monga kusonkhanitsa media ppstream, ndi mabingu wamba pa http potengera njira yofananira yomwe ingagwiritsidwe ntchito pochotsera. Kusanjana kumathandizana-malo osefera-malo osefera ndikuwombera pawiri. Khodi yoyandama imakhala yolumikizidwa pamaziko a code yokhazikika. Ndioyenera kugwiritsa ntchito zomwe zimatchulanso gawoli kuti zisasewere, koma osatchula malo omwe ali ndi gawo.
4. Kuwongolera gawo
Imafotokoza kuchuluka kwa magalimoto ndi kusinthasintha gawo lomwe gawo limalowera n mtengo (n = 1 mpaka 1024). Ndiye kuti, mapaketi oyamba a gawo lililonse amachotsedwa ndikutumizidwa ku makina omaliza omaliza, ndipo mapaketi atachotsedwa, kuyika zolemba pamwamba pa Plate. Mwambiri, mukamagwiritsa ntchito ma ids kuwunikira zochitika, simuyenera kukonza mapaketi onse a gawo lonse; M'malo mwake, mumangofunika kutulutsa mapaketi oyamba n ndi mapaketi oyamba a gawo lililonse kuti atsirize kusanthula ndi kuwunika.

Wogawanitsa amatha kuzindikira momwe amayendera ndikubwezera kwa zomwe zalembedwazo, zomwe zimatsimikizira mwayi wogwiritsa ntchito deta.
6.
Kusonkhanitsa kwa data ndi kugawa kwa ma networks 3g ndizosiyana ndi mitundu yowunikira ma netiweki. Mapaketi pa ma network a 3g amafalikira pa msana ulumikizidwe kudzera m'magawo angapo openda. Kutalika kwa mapaketi ndi mawonekedwe ophatikizika ndi osiyana ndi mapaketi pazithunzi wamba. Wogawanitsa angazindikire molondola ndikukonzekera njira yosinthira monga GTP ndi mapaketi a MPL, Milks MPLS, ndi mapaketi a vallan. Itha kuchotsa ma iups osayina mapaketi, mapaketi a GTP siginecha, ndi mapaketi a radius ku madoko omwe adakhazikitsidwa malinga ndi mapaketi a paketi. Kuphatikiza apo, imatha kugawanitsa mapaketi malinga ndi adilesi ya IP yamkati. Chithandizo cha phukusi zokulirapo (MTU> 1522 Berte) kukonza, imatha kuzindikira bwino zosonkhanitsa kwa ma network a 3G komanso shope.
Zofunikira:
- Imathandizira kugawa pamsewu ndi L2-L7 Protocol.
- Imathandizira kusefa kwa ma 5-tupler a adilesi ya IP, kopita kwa IP, gwero la port, komwe mukupita, ndi protocol komanso chigoba.
- Imathandizira kutulutsa katundu ndi kutulutsa kwam'manja ndi kulowetsedwa.
- Imathandizira kusefa ndi kutumiza ndi zingwe.
- Imathandizira kasamalidwe ka gawo. Pitilizani mapaketi oyamba a gawo lililonse. Mtengo wa n ukhoza kufotokozedwa.
- Zimathandizira ogwiritsa ntchito angapo. Mapaketi ofananira ndi lamulo lomwelo amatha kuperekedwa kwa phwando lachitatu nthawi yomweyo, kapena zomwe zili patsamba lodzola zimatha zopindika komanso zosungidwa, ndikuwonetsetsa kuti mupeze deta zingapo zogwiritsira ntchito.
Makampani ogulitsa ndalama yankho yankho labwino kwambiri
Ndi chitukuko chachangu cha ukadaulo wazidziwitso zapadziko lonse lapansi komanso zokulirapo, kuchuluka kwa bizinesi yafika pang'onopang'ono, ndipo kudalira mabungwe osiyanasiyana padongosolo chidziwitso kwayamba kuchuluka. Nthawi yomweyo, network network ya mkati ndi yakunja, zoopsa, ndi zida zambiri zotchinjiriza, kuwunikiratu, kuwunika kwapadera, kuwunika kwapadera, kuwongolera kwa Yang'anirani zida zotsika kwambiri pantchito, ndalama zambiri, ndalama zochepa, zovuta zotsala ndi zowongolera, zinthu za data ndizovuta kuwongolera.
