Lub ntsiab qhov zoo uas pob ntawv hloov muaj dhau Circuit Court switching yog nws efficiency. Pob ntawv tuaj yeem nrhiav lawv tus kheej txoj hauv kev mus rau lawv lub hom phiaj yam tsis tas yuav muaj lub siab nyiam channel. Nyob rau hauv sib piv, nyob rau hauv Circuit Court hloov cov khoom siv hauv tes hauj lwm siv tsis tau cov channel kom txog thaum lub suab sib txuas lus tau raug txiav.

Hauv qhov no, dab tsi yog qhov zoo thiab qhov tsis zoo ntawm pob ntawv hloov ntawm kev hloov hluav taws xob?

Qhov zoo thiab qhov tsis zoo ntawm Packet Switching:

  • Kev siv tau zoo ntawm Network.
  • Yooj yim mus ncig cov khoom tawg lossis pob ntawv.
  • Circuit Switching tsub tus neeg siv ntawm qhov deb thiab ntev ntawm kev sib txuas tab sis Packet Switching tsub cov neeg siv tsuas yog raws li lub sijhawm ntawm kev sib txuas.

Qhov thib ob, dab tsi yog pob ntawv hloov pauv thiab hloov hluav taws xob? Lus txhais: Pob ntawv - hloov networks txav cov ntaub ntawv nyob rau hauv nyias, me me blocks -- pob ntawv -- raws li qhov chaw nyob hauv txhua qhov pob ntawv . Thaum tau txais, pob ntawv yog reassembled nyob rau hauv raws li txoj cai los ua kom cov lus. Circuit - hloov cov tes hauj lwm xav tau kev sib txuas ntawm point-to-point thaum hu.

Tom qab ntawd, ib tus tuaj yeem nug, qhov twg yog qhov zoo dua pob ntawv hloov lossis hloov hluav taws xob?

Packet switching yog yooj yim dua thiab pheej yig dua Circuit Court hloov . Txij li tag nrho cov bandwidth tuaj yeem siv ib zaug, pob ntawv hloov yog qhov ua tau zoo dua vim nws tsis tas yuav cuam tshuam nrog qee qhov kev sib txuas uas yuav tsis siv tag nrho cov bandwidth.

Vim li cas peb thiaj xav tau pob ntawv hloov?

Pob ntawv - hloov networks - networks uas rhuav cov ntaub ntawv mus rau hauv chunks hu ua pob ntawv ua ntej kev thauj mus los - pab ua kom koj kev lag luam kev sib txuas lus ruaj khov thiab ua haujlwm tau zoo. Ib zaug tsuas yog siv rau cov ntaub ntawv thov, pob ntawv - switching yog nce siv los ua ib txoj hauv kev thauj cov suab thiab video sib txuas lus hauv lub sijhawm.
