UwitekaUmuyoboro wumuyoboro(NPB), ikubiyemo 1G NPB, 10G NPB, 25G NPB, 40G NPB, 100G NPB, 400G NPB, naUmuyoboro wo Kugerageza Umuyoboro (TAP), ni igikoresho cyuma gihita cyinjira mumurongo wurusobe kandi cyohereza igice cyitumanaho kumurongo mubindi bikoresho.
Umuyoboro wa Packet Brokers usanzwe ukoreshwa muri sisitemu yo kwinjira muri neti (IDS), ibyuma byerekana imiyoboro, hamwe na profili.Icyerekezo cy'indorerwamo.Muburyo bwo guhunga, ihuza UTP ikurikiranwa (umuhuza udafite ibimenyetso) igabanijwemo ibice bibiri nigikoresho cya TAP.Amakuru yahagaritswe ahujwe no gukusanya amakuru kugirango akusanye amakuru ya sisitemu yo kugenzura amakuru kuri interineti.
Niki Network Packet Broker (NPB) igukorera iki?
Ibintu by'ingenzi:
1. Yigenga
Nigice cyigenga cyibikoresho kandi ntabwo bigira ingaruka kumitwaro yibikoresho byurusobe bihari, bifite ibyiza byinshi kurenza indorerwamo.
Nibikoresho biri kumurongo, bivuze gusa ko bigomba guhindurwa mumurongo.Ariko, ibi nabyo bifite imbogamizi zo kumenyekanisha ingingo yo gutsindwa, kandi kubera ko ari igikoresho cyo kumurongo, umuyoboro uriho ugomba guhagarikwa mugihe cyoherejwe, ukurikije aho woherejwe.
2. Mucyo
Gukorera mu mucyo bisobanura icyerekezo kuri rezo y'ubu.Nyuma yo kugera kumurongo shunt, ntabwo bigira ingaruka kubikoresho byose murusobe rwubu, kandi biragaragara neza kuri bo.Byumvikane ko, ibi birimo na traffic yoherejwe numuyoboro shunt ku gikoresho cyo kugenzura, nacyo kibonerana kuri neti.
Ihame ry'akazi:
Guhagarika ibinyabiziga (gukwirakwiza) bishingiye ku makuru yinjiye, kwigana, gukusanya, kuyungurura, 10G POS ihinduranya amakuru binyuze muri protocole ihinduranya amakuru ya megabytes icumi ya LAN, ukurikije algorithm yihariye yo kuringaniza imizigo, ibisohoka icyarimwe kugirango ubyemeze ko paki zose zicyiciro kimwe, cyangwa IP imwe isohoka paki zose zivuye kumurongo umwe ukoresha.
Ibiranga imikorere:
1. Guhindura protocole
Inzira nyamukuru itumanaho rya interineti ikoreshwa na ISP irimo 40G POS, 10G POS / WAN / LAN, 2.5G POS, na GE, mugihe amakuru yakira interineti yakoreshejwe na seriveri ya porogaramu ni GE na 10GE LAN.Kubwibyo, ihinduka rya protocole risanzwe rivugwa kumurongo wa interineti itumanaho cyane cyane ryerekeza ku guhinduka hagati ya 40G POS, 10G POS, na 2.5G POS kuri 10GE LAN cyangwa GE, hamwe na cotransfer hagati ya 10GE WAN na 10GE LAN na GE.
2. Gukusanya amakuru no kuyakwirakwiza.
Porogaramu nyinshi zo gukusanya amakuru ahanini zikuramo traffic bitaweho no guta traffic batitayeho.Urujya n'uruza rw'amakuru ya aderesi ya IP yihariye, protocole, n'icyambu bivanwaho na tuple eshanu (aderesi ya IP, aho IP igana, aderesi ya IP, icyambu, icyambu, na protocole) guhuza.Iyo ibisohoka, isoko imwe, ahantu hamwe hamwe nuburemere buringaniye bisohoka byemejwe ukurikije algorithm ya HASH yihariye.
3. Akayunguruzo kode
Kubikusanyamakuru bya P2P, sisitemu yo gusaba irashobora kwibanda gusa kumuhanda runaka wihariye, nko gutambutsa itangazamakuru PPStream, BT, Inkuba, hamwe nijambo ryibanze kuri HTTP nka GET na POST, nibindi. no guhuza.Utandukanya ashyigikira imyanya ihamye yimiterere ya kode yo kuyungurura no kureremba kode yo kuyungurura.Ikiranga kireremba kode ni offset yerekanwe hashingiwe kumyanya ihamye yimiterere.Birakwiriye kubisobanuro byerekana kode yimiterere igomba gushungura, ariko ntugaragaze ahantu nyaburanga kode yimiterere.
4. Gucunga amasomo
Kumenya urujya n'uruza rw'amasomo kandi ruhindura neza icyiciro cyohereza N agaciro (N = 1 kugeza 1024).Nukuvuga, paki ya mbere ya buri somo yakuweho kandi ikoherezwa kuri sisitemu yinyuma-yanyuma yo gusesengura sisitemu, hamwe nudupaki nyuma ya N twajugunywe, tubika umutungo hejuru kumurongo wo gusesengura porogaramu.Muri rusange, iyo ukoresheje IDS kugirango ukurikirane ibyabaye, ntukeneye gutunganya paki zose zamasomo yose;Ahubwo, ukeneye gusa gukuramo N paki yambere ya buri somo kugirango urangize ibyabaye gusesengura no gukurikirana.
5. Kwerekana amakuru no kwigana
Gutandukana birashobora kumenya indorerwamo no kwigana amakuru kumurongo usohoka, ibyo bigatuma amakuru yinjira muri sisitemu nyinshi zikoreshwa.
6. 3G gushakisha amakuru kumurongo no kohereza
Ikusanyamakuru hamwe nogukwirakwiza kumurongo wa 3G bitandukanye nuburyo gakondo bwo gusesengura imiyoboro.Amapaki kumurongo wa 3G yoherejwe kumurongo wumugongo unyuze mubice byinshi bya encapsulation.Uburebure bwa paki nuburyo bwa encapsulation butandukanye nibipaki kumurongo rusange.Gutandukana birashobora kumenya neza no gutunganya protocole ya tunnel nka paki ya GTP na GRE, udupaki twinshi MPLS, hamwe na VLAN.Irashobora gukuramo ibipapuro byerekana ibimenyetso bya IUPS, ibipapuro byerekana ibimenyetso bya GTP, hamwe nudupapuro twa Radius ku byambu byihariye bishingiye ku biranga paki.Mubyongeyeho, irashobora kugabanya paki ukurikije aderesi ya IP imbere.Inkunga yububiko bunini (MTU> 1522 Byte) gutunganya, irashobora kumenya neza ikusanyamakuru rya 3G hamwe no gusaba porogaramu.
Ibisabwa Ibiranga:
- Gushyigikira ikwirakwizwa ryumuhanda na L2-L7 protocole ya porogaramu.
- Shyigikira 5-tuple muyunguruzi ukoresheje aderesi ya IP nyayo, aderesi ya IP yerekanwe, icyambu cyaturutse, icyambu, hamwe na protocole hamwe na mask.
- Gushyigikira ibisohoka umutwaro uringaniza nibisohoka homology na homology.
- Shyigikira gushungura no kohereza kumurongo wimiterere.
- Shyigikira imiyoborere.Kohereza mbere N paki ya buri somo.Agaciro ka N karashobora gutomorwa.
- Inkunga kubakoresha benshi.Amapaki yamakuru ahuye n amategeko amwe arashobora gutangwa mugice cya gatatu icyarimwe, cyangwa amakuru kumurongo usohoka arashobora kwerekanwa no kwigana, byemeza ko amakuru yinjira muri sisitemu nyinshi zikoreshwa.
Inganda Zimari Igisubizo Cyumuti Igisubizo
Hamwe niterambere ryihuse ryikoranabuhanga ryamakuru ku isi ndetse no kurushaho kumenyekanisha amakuru, igipimo cy’urusobe rw’ibigo cyagutse buhoro buhoro, kandi gushingira ku nganda zinyuranye kuri sisitemu y’amakuru byarushijeho kuba byinshi.Muri icyo gihe, urusobe rw’ibikorwa by’ibitero by’imbere n’imbere, ibitagenda neza, n’umutekano uhungabanya amakuru nabyo biragenda byiyongera, hamwe n’ubwinshi bwo kurinda imiyoboro, sisitemu yo kugenzura ibikorwa byashyizwe mu bikorwa bikurikiranye, uburyo bwose bwo gukurikirana ubucuruzi, ibikoresho byo kurinda umutekano byoherejwe kumurongo wose, hazabaho gutakaza umutungo wamakuru, kugenzura ahantu hatabona, kugenzura inshuro nyinshi, urusobe rwibibazo byurusobe nibibazo bidahwitse nko kudashobora kubona neza amakuru yagenewe, biganisha ku kugenzura ibikoresho bikora neza, ishoramari ryinshi, amafaranga make , gutinda kubungabunga no gucunga ibibazo, ibikoresho byamakuru biragoye kugenzura.
