Network Load Balancing (NLB) pob tshab faib tsheb hla ntau lub servers los ntawm kev siv virtual IP chaw nyob thiab lub npe sib koom.
Qhov twg hauv qab no yog qhov yuav tsum tau ua ua ntej rau NLB?
Yam yuavtsum tau kawm uantej rau NLB
- Txhua tus tswv hauv pawg NLB yuav tsum nyob hauv tib lub subnet: Qhov no tau pom zoo vim tias NLB yuav tsis ua tiav yog tias qhov latency ntawm cov nodes siab dua 250 ms.
- Txhua lub network adapters hauv ib pawg NLB yuav tsum tau teeb tsa kom siv unicast lossis multicast: Kev sib xyaw cov tsheb sib txawv no tsis txaus siab.
Nyob rau hauv qhov twg NLB pawg ua haujlwm hom yog MAC chaw nyob?
