Chii chinonzi ERPS Ring?
ERPS (Ethernet Ring Protection Switching) inzira yekudzivirira mhete yakagadzirwa neITU, inozivikanwawo seG.8032. Iyo yekubatanidza-layer protocol inonyanya kushandiswa kune Ethernet mhete. Inogona kudzivirira dutu rekutepfenyura rinokonzerwa neiyo data loop kana Ethernet mhete network yapera, uye kana chinongedzo chiri paEthernet ring network chakadzimwa, chinogona kukurumidza kudzoreredza kutaurirana pakati penodhi dzakasiyana pane network yemhete.
ERP inoshanda sei?
Batanidza Hutano Mamiriro:
Mhete yeERPS ine node dzakawanda. Ring Dziviriro Link (RPL) inoshandiswa pakati pedzimwe node kuchengetedza mhete network uye kudzivirira zvishwe kuti zvisaitike. Sezvinoratidzwa mumufananidzo unotevera, zvinongedzo pakati peChishandiso A neChishandiso B, uye pakati peChishandiso E neChishandiso F maRPL.
Munetiweki yeERP, mhete inogona kutsigira zviitiko zvakawanda, uye chiitiko chega chega chindori chine musoro. Imwe neimwe muenzaniso ine yayo protocol chiteshi, data chiteshi, uye muridzi node. Chiitiko chega chega chinoshanda sechinhu chakasiyana cheprotocol uye chinochengetedza chayo mamiriro uye data.
Mapaketi ane maID mhete akasiyana anosiyaniswa nenzvimbo yekuenda MAC kero (yekupedzisira byte yenzvimbo yekuenda MAC kero inomiririra iyo mhete ID). Kana pakiti iine ID yemhete yakafanana, iyo ERP muenzaniso kwairi inogona kusiyaniswa neVLAN ID yainotakura, kureva, iyo mhete ID uye VLAN ID iri mupaketi inosarudzika chiitiko.
Link Failure Status:
Kana node iri mune chinongedzo ikaona kuti chero chiteshi cheERPS mhete chadzikira, chinovhara chiteshi chine mhosva uye pakarepo inotumira SF packet kuti izivise kuti mamwe ma node pane chinongedzo atadza.
Sezvinoratidzwa mumufananidzo unotevera, kana chinongedzo chiri pakati peChishandiso C neDhidhiyo D chikatadza, Chidimbu C neDhidhiyo D inoona kukanganisa kwekubatanidza, vhara chiteshi chine mhosva, uye nguva nenguva tumira mameseji eSF.
Link Healing Status:
Mushure mekunge chinongedzo chakashata chadzoserwa, vhara chiteshi changa chiri mumhosho, tanga iyo nguva yekurinda, uye tumira NR packet kuti uzivise muridzi kuti yakanganisa link yadzoreredzwa. Kana muridzi node asingagamuchire SF packet nguva isati yapera, muridzi node anovhara RPL port uye nguva nenguva anotumira (NR, RB) mapaketi kana timer yapera. Mushure mekugamuchira iyo (NR, RB) pakiti, iyo yekudzoreredza node inoburitsa yakavharwa kwenguva pfupi yekudzoreredza chiteshi. Mushure mekugamuchira iyo (NR, RB) pakiti, muvakidzani node inovhara RPL chiteshi uye chinongedzo chinodzoreredzwa.
Sezvinoratidzwa mumufananidzo unotevera, kana mudziyo C neDhidhiyo D ukaona kuti chinongedzo pakati pavo chadzoreredzwa, vanovhara kwechinguva chiteshi chaive chambotadza uye kutumira meseji yeNR. Mushure mekugamuchira iyo NR meseji, Chishandiso A (muridzi node) inotanga WTR timer, iyo inovhara RPL chiteshi uye inotumira (NR, RB) mapaketi kune kunze kwenyika. Mushure meMudziyo C neDhidhiyo D kugamuchira iyo (NR, RB) meseji, vanoburitsa chiteshi chekudzorera chechinguva chakavharwa; Chishandiso B (Muvakidzani) chinovhara chiteshi cheRPL mushure mekugamuchira (NR, RB) mapaketi. Iyo link inodzoserwa kune yayo isati yatadza.
Tekinoroji maficha uye zvakanakira zveERPS
ERP Load Bancing:
Mune imwechete mhete network, panogona kunge paine data traffic kubva kune akawanda maVLAN panguva imwe chete, uye ERP inogona kuita kuyera kuyera, ndiko kuti, traffic kubva kune akasiyana VLAN inotumirwa munzira dzakasiyana. Iyo ERP mhete network inogona kukamurwa kuita kutonga VLAN uye kudzivirira VLAN.
Kudzora VLAN: Iyi parameter inoshandiswa kufambisa ERP protocol mapaketi. Imwe neimwe ERP muenzaniso ine yayo yekutonga VLAN.
Dziviriro VLAN: Kusiyana nekutonga VLAN, VLAN yekudzivirira inoshandiswa kuendesa data pakiti. Imwe neimwe ERP chiitiko ine yayo yekudzivirira VLAN, iyo inoshandiswa nekugadzirisa inotenderera yemuti muenzaniso.
Nekugadzirisa akawanda ERP zviitiko pane imwechete mhete network, dzakasiyana ERP zviitiko zvinotumira traffic kubva kune akasiyana maVLAN, kuitira kuti iyo topology yedata traffic muVLAN dzakasiyana mumhete network yakasiyana, kuitira kuti uwane chinangwa chekugovana mitoro.
Sezvinoratidzwa mumufananidzo, Instance 1 uye Instance 2 zviitiko zviviri zvakagadziridzwa muRPS mhete, iyo RPL yezviitiko zviviri zvakasiyana, chinongedzo pakati peChishandiso A neChishandiso B ndiyo RPL yeInstance 1, uye mudziyo A ndiye muridzi. node yeInstance 1. Kubatana pakati peChishandiso C neDhidhiyo D ndiyo RPL yeInstance 2, uye Decive C ndiye muridzi weInstance 2. MaRPLs ezviitiko zvakasiyana anovhara maVLAN akasiyana-siyana kuti aise kuenzanisa kwekutakura mumhete imwe chete.
High level of security:
Kune marudzi maviri eVLAN muERP, imwe iR-APS VLAN uye imwe yacho iVLAN data. R-APS VLAN inoshandiswa chete kufambisa protocol mapaketi kubva kuERPS. ERP inongogadzirisa mapaketi eprotocol kubva kuR-APS VLAN, uye haigadzirise chero protocol kurwisa mapaketi kubva ku data VLAN, inovandudza ERP chengetedzo.
Tsigira multi-loop intersection tangent:
ERP inotsigira kuwedzera mhete dzakawanda mune imwechete node (Node4) muchimiro che tangent kana mharadzano, iyo inowedzera zvakanyanya kuchinjika kwetiweki.
Yese ring ring network maindasitiri switch anotsigira ERPS mhete network networking tekinoroji, iyo inovandudza zvakanyanya kuchinjika kwetiweki, uye kukanganisa kuchinjika nguva ndeye ≤ 20ms, kuve nechokwadi kugadzikana kwakanyanya kwekumberi-yekupedzisira vhidhiyo kutumira data. Mukuwedzera, inotsigira kushandiswa kwe-single-core optical fiber kuti iite ERPS ring network kuti ione kuti hapana bhodhoro mumavhidhiyo ekuisa data, uye panguva imwechete inochengetedza zvakawanda zve optical fiber kune vatengi.
Chii chinoita ERP?
ERP tekinoroji inokodzera Ethernet ring topology inoda kuvimbika kwakanyanya uye kuwanikwa kwepamusoro. Naizvozvo, yakashandiswa zvakanyanya mune zvemari, zvekufambisa, maindasitiri otomatiki uye mamwe minda. Mundima yezvemari, masisitimu ebhizinesi akakosha anofanirwa kuve nekuvimbika kwepamusoro uye chaiyo-nguva yekufambisa data, saka ERP tekinoroji inoshandiswa zvakanyanya. Muindasitiri yezvekufambisa, uko kuvimbika kwetiweki uye kubatana kwakakosha kuchengetedzeka kweveruzhinji, tekinoroji yeERP inogona kubatsira kuvandudza kugadzikana kwetiweki mune yekuchinjana data system yering network topology. Muindasitiri otomatiki masisitimu, ERP tekinoroji inogona kubatsira network kuti ive yakavimbika, nekudaro ichiva nechokwadi chekushanda kwakajairwa kwemutsara wekugadzira. ERPS tekinoroji inogona kubatsira bhizinesi network kuwana nekukurumidza kuchinja uye kukanganisa kudzoreredza, kuve nechokwadi chekuenderera kwebhizinesi, uye kuwana millisecond-level yekubatanidza kudzoreredza, kuitira kuti inyatso kuve nechokwadi chemhando yekutaurirana kwemushandisi.
