Ibyingenzi

S5456XC ni layer-3 ihinduranya ifite 48 x 25GE (SFP +) na 8 x 100GE (QSFP28).Nibisekuru bizakurikiraho byubwenge bwoguhindura imiyoboro yabatuye hamwe nu mishinga yimishinga.Imikorere ya software yibicuruzwa irakize cyane, ihagaze neza ihagaze IPv4 / IPv6, ubushobozi bwo guhanahana, inkunga ikomeye kandi ihamye RIP / OSPF / RIPng / OSPFv3 / PIM ikoresha protocole, nibindi biranga.Imiyoboro yohereza imbere hamwe nubushobozi bwo kohereza ni nini, byujuje ibyifuzo bya data kumurongo wibanze hamwe numuyoboro wumugongo.

Ibibazo

Q1: Urashobora kumbwira kubyerekeye igihe cyo kwishyura?

Igisubizo: Kubitegererezo, kwishura 100% mbere.Kubicuruzwa byinshi, T / T, 30% yishyuwe mbere, 70% asigaye mbere yo koherezwa.

Q2: Igihe cyawe cyo gutanga kimeze gute?

Igisubizo: 30-45days, niba kugenera cyane, bizatwara igihe gito.

Q3: ONTs / OLTs yawe irashobora guhuzwa nibicuruzwa byabandi?

Igisubizo: Yego, ONTs / OLTs zirahuza nibicuruzwa byabandi munsi ya protocole isanzwe.

Q4: Igihe cya garanti yawe kingana iki?

Igisubizo: Umwaka 1.

Q5: Ni irihe tandukaniro riri hagati ya EPON GPON OLT na XGSPON OLT?

Itandukaniro rinini nuko XGSPON OLT ishyigikira GPON / XGPON / XGSPON, Umuvuduko Wihuse.

Q6: Nubuhe buryo bwemewe bwo kwishyura muri sosiyete yawe?

Kurugero, kwishura 100% mbere.Kuburyo bwicyiciro, T / T, 30% kubitsa, 70% asigaye mbere yo kubyara.

Q7: Isosiyete yawe ifite ikirango cyayo?

Nibyo, ikirango cyisosiyete yacu ni Limee.Icyerekezo cya Layeri 3 ni ubwoko bwa rezo ya rezo ikorera kumurongo wa moderi ya OSI.Ibi bivuze ko ifite ubushobozi bwo gufata ibyemezo byo guhitamo bishingiye kuri aderesi ya IP, kimwe na router.Igice cya 3 cyahinduwe gikunze gukoreshwa murusobekerane rwibikorwa kugirango uhuze subnets zitandukanye kandi ufate ibyemezo byerekeranye naho ujya imbere traffic.

None, mubyukuri ni ubuhe buryo bwa Layeri 3 kandi butandukaniye he na gakondo ya Layeri 2?Inzira ya Layeri 2 ikora kumurongo wamakuru uhuza moderi ya OSI kandi ifata ibyemezo byo kohereza bishingiye kuri aderesi ya MAC.Mugihe ikora neza mugutezimbere traffic muri subnet imwe, ibura ubushobozi bwo gufata ibyemezo byumuhanda kumodoka igana kuri subnet zitandukanye.Aha niho haza Layeri ya 3.

Inzira ya Layeri 3 ihuza imikorere ya gakondo ya Layeri 2 hamwe nubushobozi bwo kuyobora bwa router.Irashoboye gukora LANs (VLANs) no kuyobora traffic hagati yabo, kimwe no gufata ibyemezo bijyanye n'inzira nziza yimodoka zinyura mumurongo.Ibi bituma iba igikoresho gikomeye cyo gucunga no gutezimbere urujya n'uruza mu miyoboro minini, igoye.

Imwe mu nyungu zingenzi zo gukoresha Layeri 3 ni ubushobozi bwayo bwo kunoza imikorere y'urusobe.Mugukuraho bimwe mubikorwa byurugendo ruva kumurongo wibanze kugeza kuri Layeri 3, urujya n'uruza rushobora gukwirakwizwa neza, biganisha ku itumanaho ryihuse kandi ryizewe hagati yibikoresho kumurongo.

Muri rusange, Layeri ya 3 ni umutungo w'agaciro kumiryango ifite imiyoboro ikenewe.Ubushobozi bwayo bwo guhuza imikorere ya switch na router bituma iba ikintu cyingenzi mugucunga no gutezimbere urujya n'uruza.Mugihe ubucuruzi bukomeje gushingira kumurongo ukomeye kandi unoze, imiyoboro ya Layeri 3 izakomeza kugira uruhare runini mugukora ibishoboka byose kugirango amakuru agende neza kandi yizewe murusobe.
