Nanini na inkqubo yakho ikhula, ukunyuka kwetrafikhi, abasebenzisi abaninzi ngakumbi basebenzisa iimveliso zakho, iiseva ziqala ukuphendula kancinci, ixesha lokuphumla linyanzela ishishini lakho ukuba libandezeleke emva koko uqale ukucinga malunga nokunyusa.
Kukho iindlela ezimbini eziphambili zokulinganisa - ngokuthe nkqo kunye nokuthe tye.
Ukukala okuthe nkqo kujonge ukonyusa amandla enkqubo ngokongeza rhoqo i-CPU, kunye ne-RAM kwiiseva zakho.
Ngokwahlukileyo, ukukala okuthe tye kugxininise ekuphindaphindeni (okanye ukudibanisa) iiseva zakho kwiqula lezixhobo.
Okungakumbi kwezi:
Ukukala ngokuthe nkqo yeyona ndlela ilungileyo yenkqubo yezithuthi eziphantsi kuba yeyona ndlela ifikelelekayo yokuphatha ukukhula ngaphandle kokwazisa ubunzima obongezelelweyo. Awudingi ukukhathalela malunga nokuthumela izicwangciso zeqela lezixhobo, ukuqina kwesixhobo semithombo, ukungabi nabume komncedisi wakho, i-cache esasaziweyo, njalo njalo.
Nangona kunjalo, ukukala okuthe nkqo kuneengxaki ezinkulu
Ukukala okuthe tye kuphelisa ezi ngxaki ngokwenza iiseva zesicelo sakho kwaye uzinzise inxalenye efana nesilinganisi somthwalo .
Isilinganisi somthwalo sisasaza itrafikhi kwiiseva zakho sisebenzisa iialgorithms ezithile ezinje:
Nangona kunjalo, inezithintelo ezininzi:
Kwizixhobo ezibini kwi-intanethi ukunxibelelana omnye komnye, iinkqubo ezisisiseko kufuneka zilandele iiprothokholi ezithile. Wonke umntu weva ngemodeli ye-OSI, echaza iileya ezisixhenxe ezisetyenziswa ziinkqubo zekhompyuter ukunxibelelana ngenethiwekhi. Nangona i-intanethi yanamhlanje isekwe kwimodeli ye-protocol ye-TCP/IP elula, imodeli ye-OSI isetyenziswa kakhulu, njengoko inceda ukubona nokunxibelelana ngendlela uthungelwano olusebenza ngayo kwaye inceda ukwahlula kunye nokusombulula iingxaki zothungelwano.
Uninzi lwezisombululo zokulinganisa umthwalo woshishino zisebenzisa amagama e-L4 kunye ne-L7 apho i-L4 ibhekisela kuluhlu lwezothutho kwimodeli ye-OSI kunye ne-L7 ibhekisela kuluhlu lwesicelo.
I-balancer yomthwalo we-L4 iseyi-L2/L3 ekubeni isebenzisa idatha esuka kumaleko asezantsi njengedilesi ye-IP kunye nenombolo ye-port.
Ikhuseleke ngakumbi kwaye iyaqhuba njengoko umxholo wedatha ungathathwanga ekwenzeni izigqibo zomzila
Uxhulumaniso olufanayo lwe-TCP lubambe phakathi komxhasi kunye nomncedisi, onceda ukunqanda ukugqithiswa komda wodibaniso olukhoyo lwe-TCP kwi-balancer yomthwalo.
Ngakolunye uhlangothi, i-balancer yomthwalo we-L7 isebenza kwinqanaba lesicelo kwimodeli ye-OSI
Izigqibo ezihlakaniphile zingenziwa ngokusekelwe kwindlela ye-URL, iintloko, umxholo
Ugcino
Isilinganisi sokulayishwa licandelo elibalulekileyo xa ukukala okuthe tye kusetyenziswa ukujongana neenkqubo zetrafikhi ephezulu. Kukho iindidi ezimbini eziphambili zokulinganisa umthwalo we-L4 kunye ne-L7.
Isilinganisi somthwalo se-L4 sikhuseleke ngakumbi kwaye sisebenza ngenxa yothintelo lokwenza izigqibo ezikrelekrele
I-L7 ibhalansi yomthwalo isebenza ngendlela yokubonelela ngezigqibo zomzila ezikrelekrele ngenxa yeendleko zokusebenza kakuhle kunye nokhuseleko
Ukukhetha uhlobo olufanelekileyo kuxhomekeke kwiimfuno zenkqubo kwaye kufuneka kuqwalaselwe ngononophelo kunye nebhalansi efanelekileyo yokusebenzisa imigaqo yokhuseleko kunye nokuphelisa imiqobo yokusebenza.
Kwakhona ipapashwe apha.
