Indlela yokwahlula kwaye ukhethe iiswitshi?
Utshintsho lusetyenziswa ngokubanzi kwiiprojekthi zenethiwekhi zangoku ezibuthathaka, kwaye zonke iintlobo zokuhanjiswa kwedatha azinakwahlulwa kuzo. NamhlanjeI-JHA Techiya kuthetha malunga nokuhlelwa kunye nokukhethwa kwezinto ezibhekiselele kwiiswitshi.
- Ukuhlelwa kweeswitshi
- I-1-1 Ngokuhambelana nesakhiwo sothungelwano: yahlulwe kwi-switch layer yokufikelela, i-aggregation layer switch kunye ne-core layer.
I-1-2Ngokutsho kwemodeli ye-OSI: ihlulwe kwi-switch switch ye-2, i-3 switch switch, i-4 ye-switch switch, njl., yonke indlela yokutshintshela kwi-7.
I-1-3 Ukulawulwa kokutshintsha: Umahluko phakathi kokutshintsha okulawulwayo kunye nokutshintsha okungalawulwayo kuxhomekeke kwinkxaso yabo kwiiprotocol zolawulo lwenethiwekhi ezifana ne-SNMP kunye ne-RMON.
I-JHA Tech, ngaba umenzi wokuqala unikezelwe kwi-R & D, imveliso, kunye nokuthengiswa kwe-Ethernet Switshi, iMedia Converter, i-PoE Switch & Injector kunye nemodyuli ye-SFP kunye neemveliso ezininzi ezinxulumene ne-17 iminyaka. Inkxaso OEM, ODM, SKD njalo njalo.
Kwakhona ube nonikezelo lwemveliso olupheleleyo, iqela eliqinileyo le-R&D, indlela yokuphendula ngokukhawuleza emva kokuthengisa, kunye namava esicelo sesisombululo esiqolileyo.
I-JHA Tech ineqela lobuchwephesha lobuchwephesha elinabantu abangaphezu kwama-20 abanamava okusebenza aphakathi kweminyaka eli-15, kwaye inokusombulula ingxaki yakho ngemizuzu engama-30 ngokukhawuleza.
2.Imiba ephambili yereferensi yokukhethwa kokutshintsha
a.Backplane bandwidth, Umaleko 2/3 ukutshintsha throughput.
b.VLAN uhlobo kunye nenombolo.
c.Inombolo kunye nodidi lwamazibuko okutshintsha.
d.Inkxaso yolawulo lweeprothokholi zothungelwano kunye neendlela. Utshintsho luyafuneka ukubonelela ngolawulo olulula ngakumbi kunye nolwendawo esembindini.
e, Qos, 802.1q ulawulo oluphambili, 802.1X, 802.3X inkxaso.
f.Inkxaso yokupakisha.
g.Tshintsha i-cache yokutshintsha, i-port cache, inkumbulo engundoqo, ulibaziseko logqithiso kunye nezinye iiparamitha.
I-h.Ukuhanjiswa kwesantya somgca, ubungakanani betafile yomzila, ubungakanani boluhlu lolawulo lokufikelela, ukuxhaswa kweeprotokholi zomzila, ukuxhaswa kweeprotocol ze-multicast, iindlela zokucoca iipakethi, amandla okwandisa umatshini, njl. Zonke iiparameters zifanele ziqwalaselwe kwaye kufuneka ziphandwe ngokusekelwe kwimeko yangempela.
Ukuba ufuna isisombululo sokukhetha utshintsho, nceda ushiye idilesi yakho ye-imeyile kwaye siya kuba nengcali yoqhagamshelwano nawe ukuze ufumane iimpendulo zomntu ngamnye.
