Iyo network yekutarisa sisitimu inotora nzvimbo yakakwana muprojekiti yekuchengetedza. Mune yepamusoro-tsanangudzo yetiweki vhidhiyo yekutarisa sisitimu, pane kazhinji zviitiko zvakadai sekunonoka kwemifananidzo uye kuomesa. Pane zvikonzero zvakawanda zvezviitiko izvi, asi kazhinji, iyo switch configuration haina musoro zvakakwana, zvichikonzera kusakwana bandwidth. Shanduko chinhu chakakosha cheiyo system yese. Kunyangwe iyo yakagadziriswa nemazvo kana kwete inokanganisa zvakananga kugadzikana kwekupedzisira kweiyo network yekutarisa system.

Paunenge uchisarudza shanduko, iwe unofanirwa kusarudza kubva kune bandwidth uye packet kutumira mwero. Iyo backplane bandwidth ndiyo yakanyanya kuwanda yedata inogona kubatwa pakati peiyo switch interface processor kana interface kadhi uye data bhasi. Iyo inocherekedza iyo yakazara data yekuchinjana kugona kweiyo switch, iyo yakakwira iyo backplane bandwidth, iyo yakasimba kugona kugadzirisa data. Packet forwarding rate inonziwo port throughput, zvinoreva kukwanisa kwe router kuendesa mberi data packet pachiteshi. Iyo yakakwirira iyo packet yekufambisa mwero, zviri nani.

Panyaya yetiweki topology, yepakati uye yakakura-yepamusoro-tsanangudzo yetiweki vhidhiyo yekutarisa system inoda kutora matatu-layer network yekuvaka: yekupinda layer, convergence layer, uye core layer.

Ungasarudza seiaccess layer switch?
Iyo yekupinda layer switch inonyanya kubatana kune yekumberi-yekupedzisira network yakakwira-tsanangudzo kamera uye yakabatana neaggregation switch. Kubva pane 4M kodhi rwizi rwe1080P network makamera, mangani machannel e1080P network makamera anogona kubatanidzwa kune imwechete 100M port access switch?

Iyo chaiyo bandwidth yekuchinja kwedu kunowanzo shandiswa i50% -70% yeiyo theoretical kukosha, saka iyo chaiyo bandwidth ye100M port ndeye 50M-70M. 4M*12=48M, saka zvinokurudzirwa kuti imwe 100M yekupinda switch inokwanisa kubatana nepamusoro pe12 1080P network makamera. Panguva imwecheteyo, tichifunga kuti ikozvino yekutarisa network inotora ine simba encoding, iyo yepamusoro kukosha kweiyo kamera kodhi rwizi inogona kudarika 4M bandwidth, uye bandwidth redundancy dhizaini inotariswa zvakare. Naizvozvo, zvakanakisa kana 100M yekupinda switch ichidzorwa mukati me8 units, uye anopfuura 8 mayuniti anokurudzirwa. Gigabit port. Mune mamwe maitiro e-ultra-high-definition network monitoring systems, kuitira kuti ave nechokwadi chepamusoro-tsanangudzo yemifananidzo yevhidhiyo uye kuvimbika kwepamusoro kwekutumira data, iyo yekuwana layer inogonawo kusarudza zvakananga Gigabit switches.

Ungasarudza sei aggregation layer switch?

Iyo aggregation layer switch inonyanya kubatanidzwa kune yekupinda layer switch uye yepakati switch yeuplink yekutarisa nzvimbo. Kuitwa kwacho kwakakwira kupfuura kweiyo yekuwana switch. Mumamiriro ezvinhu akajairwa, switch yekubatanidza inoda kusarudza Layer 2 switch ine gigabit upload port. Iyo 100M chiteshi cheiyo switch yakabatana kune switch, uye chiteshi cheGigabit chakabatana kune yakakosha switch yenzvimbo yekutarisa. Nhamba yekubatanidza pane aggregation switch inofanira kudzorwa mukati me30. Ichiri kuverengwa zvichienderana ne4M code stream ye1080P network kamera. Imwe neimwe yekupinda layer switch kumucheto kumberi ine 6 1080P network makamera, uye aggregation switch yakabatana ne5 yekuwana layer switch. Iyo yakazara bandwidth yeaggregation switch ndeye 4M * 6 * 5 = 120M, saka cascade port yeaggregation switch uye yepakati switch inofanira kunge iri gigabit port.

Ungasarudza sei core switch?

Iyo yepakati layer switch inonyanya kubatanidzwa neaggregation layer switch, iyo uplink yekutarisa nzvimbo yekutarisa vhidhiyo chikuva, yekuchengetedza server, dijitari matrix nemimwe michina, inova musimboti weiyo yese yepamusoro-tsanangudzo network yekutarisa system.then kusarudza yepakati switch, iwe unofanirwa kufunga nezve bandwidth kugona kwehurongwa hwese uye maitiro ekugadzirisa iyo core layer switch zvisina kunaka, izvo zvinozoita kuti vhidhiyo skrini ikundikane kuratidza zvakanaka.saka, nzvimbo yekutarisa. inokurudzira kusarudza yakazara gigabit core switch. Kana paine akawanda mapoinzi, maVLAN anoda kukamurwa, uye matatu-layer yakazara Gigabit core switch inofanira kusarudzwa. Iyo yakakura-yakakura yekutarisa system ine anopfuura zana nemakumi mashanu kamera inofanirwa kufunga matatu-layer 10 Gigabit core switch.

Mapoinzi akakosha ekusarudza switch
Paunenge uchisarudza switch yekutarisa vhidhiyo munharaunda yenzvimbo network, nekuti iyo huru yekumanikidza iri pane aggregation layer switch, iyo aggregation layer switch inofanirwa kutakura kudzvanywa kwekutarisa nekuchengetedza traffic pamwe nekumanikidza kwechokwadi-nguva yekuona uye kufona. monitoring. Naizvozvo, zvinonyanya kukosha kusarudza inoshanda aggregation switch. Inokurudzirwa kusarudza gigabit inogadziriswa switch, iyo inogona kugadzirisa network, optimize uye kuwedzera bandwidth chiyero chekushandisa, uye kuve nechokwadi kutsetseka kwekutapurirana.

Zvekungwaririra
Kana ukasarudza Web-managed switch management, zvichava nyore. Zvakanakisisa kusarudza speed-limiting switch, uye pakusarudza shanduko ine cache yakakura, panguva imwecheteyo, network monitoring system inoda kugadzikana kwepamusoro uye chaiyo-nguva yekushanda, uye nzvimbo yekushanda yemidziyo yakaoma uye yakaoma, saka. yekudzivirira Kutepfenyura kwakadzikama uye kwakanaka kwe data system, zvinokurudzirwa kusarudza maindasitiri Ethernet switch zvigadzirwa zvine yakakwira maindasitiri kuita uye kugadzikana kwakanaka.
