Yintoni i-ERPS Ring?
I-ERPS (i-Ethernet Ring Protection Switching) yiprotocol yokukhusela iringi eyenziwe yi-ITU, eyaziwa ngokuba yi-G.8032. Yiprotocol yekhonkco-umaleko osetyenziswa ngokukodwa kwizangqa ze-Ethernet. Inokuthintela isaqhwithi sosasazo esibangelwa yi-loop yedatha xa inethiwekhi ye-Ethernet ring igqityiwe, kwaye xa ikhonkco kwinethiwekhi ye-Ethernet ring inqanyuliwe, inokubuyisela ngokukhawuleza unxibelelwano phakathi kweenodi ezahlukeneyo kwinethiwekhi yendandatho.
Isebenza njani iERP?
Unxulumano lweSimo seMpilo:
Iringi ye-ERPS iqulethe iindawo ezininzi. I-Ring Protection Link (RPL) isetyenziswa phakathi kwezinye iindawo ukukhusela umnatha weringi kunye nokuthintela iilophu ukuba zingenzeki. Njengoko kubonisiwe kulo mfanekiso ulandelayo, ikhonkco phakathi kweDivaysi A kunye neDivaysi B, kwaye phakathi kweDivaysi E kunye neDivaysi F zii-RPLs.
Kwinethiwekhi ye-ERP, iringi inokuxhasa iimeko ezininzi, kwaye umzekelo ngamnye ngumsesane onengqiqo. Umzekelo ngamnye unetshaneli yayo yeprotocol, ishaneli yedatha, kunye nenode yomnini. Umzekelo ngamnye usebenza njengequmrhu leprothokholi elahlukileyo kwaye ligcina ilizwe lalo kunye nedatha.
Iipakethi ezine-ID zeringi ezahlukeneyo zohlulwa ngedilesi ye-MAC yendawo yokufikela (i-byte yokugqibela yendawo yokufikela idilesi ye-MAC imele i-ID yeringi). Ukuba ipakethi ine-ID efanayo yeringi, umzekelo we-ERP ekuyo unokwahlulwa nge-ID ye-VLAN ephetheyo, oko kukuthi, i-ID yeringi kunye ne-ID ye-VLAN ekwipakethi yokuchonga ngokukodwa umzekelo.
Ubume bokusilela konxulumano:
Xa i-node kwikhonkco ifumanisa ukuba nayiphi na i-port ye-ERPS ring iphantsi, ivala i-port ephosakeleyo kwaye ngokukhawuleza ithumele ipakethe ye-SF ukwazisa ukuba ezinye iindawo ezikukhonkco aziphumelelanga.
Njengoko kuboniswe kulo mfanekiso ulandelayo, xa ikhonkco phakathi kweDivaysi C kunye neDivaysi D ihluleka, iDivaysi C kunye neDivaysi D ibona iphoso lekhonkco, vimba i-port ephosakeleyo, kwaye ngezikhathi ezithile uthumele imiyalezo ye-SF.
Ubume bokuPhilisa ikhonkco:
Emva kokuba ikhonkco eliphosakeleyo libuyiselwe, vimba i-port eyayikwimeko yempazamo, qalisa isibali-xesha sokulinda, kwaye uthumele ipakethe ye-NR ukwazisa umnini ukuba ikhonkco eliphosakeleyo libuyiselwe. Ukuba i-node yomnini akayifumani ipakethi ye-SF ngaphambi kokuba isibali-xesha siphele, i-node yomnini ivimba i-port ye-RPL kwaye ngamaxesha athile ithumela iipakethi (NR, RB) xa isibali-xesha siphelile. Emva kokufumana (NR, RB) ipakethe, indawo yokubuyisela ikhupha i-port evaliweyo yokubuyisela impazamo okwethutyana. Emva kokufumana ipakethe (NR, RB), i-node yommelwane ivimba i-port ye-RPL kwaye ikhonkco ibuyiselwe.
Njengoko kubonisiwe kulo mzobo ulandelayo, xa iDivaysi C kunye neDivaysi D ibona ukuba ikhonkco phakathi kwabo ibuyiselwe, ivimba okwethutyana i-port eyayikade ikwimeko engaphumeleliyo kwaye ithumele umyalezo we-NR. Emva kokufumana umyalezo we-NR, i-Device A (i-node yomnini) iqala i-timer ye-WTR, evimba i-port ye-RPL kwaye ithumele (i-NR, i-RB) iipakethi kwihlabathi langaphandle. Emva kokuba iDivaysi C kunye neDivaysi D ifumana umyalezo (i-NR, i-RB), ikhulula i-port evaliweyo yokubuyisela okwethutyana; Isixhobo B (Ummelwane) sivimba i-port ye-RPL emva kokufumana (i-NR, i-RB) iipakethi. Ikhonkco libuyiselwe kwimeko yalo yangaphambili yokusilela.
Iimpawu zobugcisa kunye neenzuzo ze-ERPS
ERP Load Balancing:
Kwinethiwekhi efanayo yendandatho, kunokubakho i-data yedatha evela kwii-VLAN ezininzi ngexesha elinye, kwaye i-ERP inokuphumeza ukulinganisa umthwalo, oko kukuthi, i-traffic evela kwii-VLAN ezahlukeneyo ithunyelwa kwiindlela ezahlukeneyo. Inethiwekhi yeringi ye-ERP inokwahlulwa ibe yiVLAN yolawulo kunye nokhuseleko lweVLAN.
Lawula iVLAN: Le parameter isetyenziselwa ukuhambisa iipakethi ze-ERP protocol. Umzekelo ngamnye we-ERP unolawulo lwayo lweVLAN.
I-VLAN yokukhusela: Ngokuchasene ne-VLAN yokulawula, i-VLAN yokukhusela isetyenziselwa ukuhambisa iipakethi zedatha. Umzekelo we-ERP ngamnye unokhuseleko lwe-VLAN, oluphunyezwa ngokuqwalasela umzekelo womthi ojikelezayo.
Ngokuqwalasela iimeko ezininzi ze-ERP kuthungelwano lwendandatho efanayo, iimeko ezahlukeneyo ze-ERP zithumela i-traffic evela kwii-VLAN ezahlukeneyo, ukwenzela ukuba i-topology yedatha yedatha kwii-VLAN ezahlukeneyo kuthungelwano lwendandatho yahluke, ukuze kufezekiswe injongo yokwabelana ngomthwalo.
Njengoko kuboniswe kumfanekiso, i-Instance 1 kunye ne-Instance 2 yimizekelo emibini elungiselelwe kwindandatho ye-ERPS, i-RPL yeemeko ezimbini zihlukile, ikhonkco phakathi kweDivaysi A kunye neDivaysi B yi-RPL ye-Instance 1, kunye ne-Device A ngumnini. i-node ye-Instance 1. Ikhonkco phakathi kweDivaysi C kunye neDivaysi D yi-RPL ye-Instance 2, kunye ne-Decive C ngumnini we-Instance 2. Ii-RPL zeziganeko ezahlukeneyo zivimba ii-VLAN ezahlukeneyo ukuphumeza ukulinganisa umthwalo kwindandatho enye.
Inqanaba eliphezulu lokhuseleko:
Kukho iindidi ezimbini zeVLAN kwi-ERP, enye yi-R-APS VLAN kwaye enye yi-VLAN yedatha. I-R-APS VLAN isetyenziselwa kuphela ukuthumela iipakethi zeprotocol ukusuka kwi-ERPS. I-ERP isebenza kuphela iipakethi zeprotocol ukusuka kwi-R-APS VLANs, kwaye ayiqhubeki nayiphi na ipakethe yokuhlaselwa kweprotocol ukusuka kwiiVLAN zedatha, ukuphucula ukhuseleko lwe-ERP.
Ixhasa i-tangent ye-multi-loop intersection:
I-ERP isekela ukongeza amakhonkco amaninzi kwi-node efanayo (i-Node4) ngendlela ye-tangent okanye i-intersection, eyandisa kakhulu ukuguquguquka kwenethiwekhi.
Zonke i-ring network switch zamashishini zixhasa i-ERPS ring network networking technology, ephucula kakhulu ukuguquguquka kwenethiwekhi, kunye nexesha lokuguqulwa kwempazamo ngu-≤ 20ms, ukuqinisekisa ukuzinza okuphezulu kokusasazwa kwedatha yevidiyo. Ukongeza, ixhasa ukusetyenziswa kwe-fiber optical single-core ukwenza i-ERPS inethiwekhi yendandatho yokuqinisekisa ukuba akukho mbhobho ekufakweni kwedatha yevidiyo, kwaye kwangaxeshanye igcina izibonelelo ezininzi zefiber optical kubathengi.
Yenza ntoni iERP?
Itekhnoloji ye-ERP ifanelekile kwi-Ethernet ring topology ezifuna ukuthembeka okuphezulu kunye nokufumaneka okuphezulu. Ke ngoko, isetyenziswe ngokubanzi kwezemali, kwezothutho, kwimizi-mveliso ezenzekelayo kunye namanye amasimi. Kwintsimi yezemali, iinkqubo eziphambili zoshishino kufuneka ziqinisekise ukuthembeka okuphezulu kunye nokuhanjiswa kwedatha yangempela, ngoko iteknoloji ye-ERP isetyenziswa ngokubanzi. Kwishishini lezothutho, apho ukuthembeka kwenethiwekhi kunye nokudibanisa kubaluleke kakhulu kukhuseleko loluntu, iteknoloji ye-ERP inokunceda ukuphucula ukuzinza kwenethiwekhi kwinkqubo yokutshintshiselana kwedatha ye-topology ye-ring network. Kwiinkqubo ze-automation ye-industrial, iteknoloji ye-ERP inokunceda inethiwekhi ukuba ithembeke ngakumbi, ngaloo ndlela iqinisekisa ukusebenza okuqhelekileyo komgca wokuvelisa. Itekhnoloji ye-ERPS inokunceda uthungelwano lwamashishini lufezekise utshintsho olukhawulezileyo kunye nokubuyiswa kwempazamo, ukuqinisekisa ukuqhubeka kweshishini, kunye nokufezekisa ukubuyiswa kwekhonkco le-millisecond-level, ukuze kuqinisekiswe ngokufanelekileyo umgangatho wonxibelelwano lomsebenzisi.
