Ndiqinisekile ukuba uyawazi umzabalazo phakathi kweTap yeNethiwekhi (iNdawo yoFikelelo yoVavanyo) kunye nesihlalutyi sesibuko sokutshintsha (izibuko le-SPAN) ngeenjongo zokubeka iliso kuNxibelelwano.Bobabini banamandla okubonisa i-traffic kwinethiwekhi kwaye bayithumele kwizixhobo zokhuseleko ezingaphandle kwebhendi ezifana neenkqubo zokubona ukungena, abagawuli benethiwekhi, okanye abahlalutyi benethiwekhi.Izibuko ze-Spa ziqwalaselwe kutshintsho lweshishini lomsebenzi womnatha ezinomsebenzi wesibuko sezibuko.Lizibuko elizinikeleyo kwiswitshi elawulwayo ethatha ikopi yesipili yetrafikhi yenethiwekhi ukusuka kutshintshile ukuthumela kwizixhobo zokhuseleko.I-TAP, kwelinye icala, sisixhobo esasaza itrafikhi yenethiwekhi ukusuka kwinethiwekhi ukuya kwisixhobo sokhuseleko.I-TAP ifumana itrafikhi yenethiwekhi kuwo omabini amacala ngexesha lokwenyani nakwitshaneli eyahlukileyo.
Ezi zezona zibonelelo zintlanu ziphambili ze-TAP ngezibuko le-SPAN:
1. I-TAP ibamba ipakethi nganye!
I-Span Icima iipakethi ezonakeleyo kunye neepakethi ezincinci kunobungakanani obuncinci.Ke ngoko, izixhobo zokhuseleko azinakufumana zonke iitrafikhi kuba izibuko ze-span zinika ingqwalaselo ephambili kwitrafikhi yenethiwekhi.Ukongeza, i-RX kunye ne-TX ye-traffic idityaniswe kwizibuko elinye, ngoko ke iipakethi zinokwenzeka ukuba ziwiswe.I-TAP ibamba zonke iindlela ezimbini zokuhamba kwizibuko ngalinye ekujoliswe kulo, kuquka iimpazamo zezibuko.
2. Isisombululo esipheleleyo, akukho lungiselelo lwe-IP okanye unikezelo lwamandla olufunekayo
I-Passive TAP isetyenziswa ikakhulu kuthungelwano lwefiber optic.Kwi-TAP ye-passive, ifumana i-traffic evela kumacala omabini othungelwano kwaye ihlukanise ukukhanya okungenayo ukuze i-100% ye-traffic ibonakale kwisixhobo sokubeka iliso.I-Passive TAP ayifuni naluphi na unikezelo lwamandla.Ngenxa yoko, zongeza umaleko wokuphindaphinda, zifuna ukugcinwa okuncinci, kunye nokunciphisa iindleko ezipheleleyo.Ukuba uceba ukubeka iliso kwitrafikhi ye-Ethernet yobhedu, kufuneka usebenzise i-TAP esebenzayo.I-TAP esebenzayo ifuna umbane, kodwa i-Active TAP ye-Niagra iquka iteknoloji yokungaphumeleli ekhuselekileyo esusa umngcipheko wokuphazamiseka kwenkonzo kwimeko yokucima kombane.
3. Ilahleko yepakethe yeZero
I-TAP yenethiwekhi ibeka iliso kuzo zombini iziphelo zekhonkco ukubonelela nge-100% ukubonakala kweendlela ezimbini zothutho lwenethiwekhi.I-TAP ayilahli naziphi na iipakethi, nokuba zithini na umda wazo.
4. Ilungele ukusetyenziswa kothungelwano oluphakathi ukuya phezulu
Izibuko le-SPAN alinakukwazi ukusebenzela amakhonkco othungelwano asetyenziswa kakhulu ngaphandle kokulahla iipakethi.Ngoko ke, i-TAP yothungelwano iyafuneka kwezi meko.Ukuba i-traffic eninzi iphuma kwi-SPAN kunokuba ifunyenwe, i-port ye-SPAN iba kubhaliswa ngokugqithisileyo kwaye kunyanzelekile ukuba ilahle iipakethi.Ukubamba i-10Gb yeendlela ezimbini zokuhamba, i-port ye-SPAN idinga i-20Gb yomthamo, kunye ne-10Gb Network TAP iya kukwazi ukubamba yonke i-10Gb yomthamo.
5. TAP Ivumela zonke iitrafikhi ukuba zidlule, kuquka iithegi zeVLAN
Izibuko ze-Span azivumeli iilebhile ze-VLAN ukuba zidlule, nto leyo eyenza kube nzima ukubona iingxaki ze-VLAN kunye nokudala iingxaki zomgunyathi.I-TAP inqanda iingxaki ezinjalo ngokuvumela zonke iitrafikhi zidlule.
