Momwe mungasinthire ndikusankha masiwichi?
Masinthidwe amagwiritsidwa ntchito kwambiri pamapulojekiti ofooka apano apaintaneti, ndipo mitundu yonse yotumizira ma data ndi yosiyana ndi iwo. LeroJHA Techidzalankhula za magulu ndi zosankha zofotokozera za ma switch.
- Gulu la masiwichi
- 1-1 Kutengera mawonekedwe a netiweki: imagawidwa kukhala masiwichi ofikira, masiwichi ophatikizika ndi masiwichi apakati.
1-2Malingana ndi mtundu wa OSI: imagawidwa kukhala masiwichi osanjikiza 2, masiwichi osanjikiza 3, masiwichi osanjikiza 4, ndi zina zotere, mpaka 7 masiwichi.
1-3 Kuwongolera kwa masinthidwe: Kusiyana pakati pa masiwichi oyendetsedwa ndi masinthidwe osayendetsedwa ndikuthandizira kwawo ma protocol oyang'anira maukonde monga SNMP ndi RMON.
JHA Tech, ndi omwe amapanga choyambirira adadzipereka ku R&D, kupanga, ndikugulitsa ma Ethernet Switches, Media Converter, PoE Switch & Injector ndi module ya SFP ndi zinthu zambiri zokhudzana ndi zaka 17. Support OEM, ODM, SKD ndi zina zotero.
Khalaninso ndi katundu wathunthu, gulu lolimba la R&D, njira yoyankha mwachangu mukagulitsa, komanso luso logwiritsa ntchito mayankho okhwima.
JHA Tech ili ndi gulu laukadaulo la anthu opitilira 20 omwe akugwira ntchito kwazaka zopitilira 15, ndipo amatha kuthana ndi vuto lanu mkati mwa mphindi 30 mwachangu kwambiri.
2.Main zofotokozera za kusankha kusintha
a.Backplane bandwidth, Layer 2/3 switching throughput.
b.VLAN mtundu ndi nambala.
c.Nambala ndi mtundu wa madoko osinthira.
d.Support network management protocols ndi njira. Masinthidwe amafunikira kuti apereke kasamalidwe kosavuta komanso kapakati.
e, Qos, 802.1q kuwongolera patsogolo, 802.1X, 802.3X thandizo.
f. Stacking thandizo.
g.Switch switching cache, port cache, main memory, kuchedwetsa kutumiza ndi zina.
h.Line liwiro kutumizira, kukula kwa tebulo loyendetsa, kukula kwa mndandanda wolowera, kuthandizira ndondomeko zamayendedwe, kuthandizira ma protocol ambiri, njira zosefera paketi, mphamvu zowonjezera makina, ndi zina zonse ndizofunika kuziganizira ndipo ziyenera kufufuzidwa potengera momwe zinthu zilili.
Ngati mukufuna yankho la kusankha chosinthira, chonde siyani imelo yanu ndipo tidzakhala ndi katswiri wolumikizana nanu kuti mupeze mayankho amodzi ndi amodzi.
