Umahluko phakathi kwe-aloha esulungekileyo kunye ne-aloha eslotthiweyo

I-Aloha yenye yeeprothokholi ezisisiseko kwiinethiwekhi ze-LAN kunye ne-WAN. Le protocol ye-carrier sense access multiple (CSMA) isetyenziswa kuthungelwano lwengingqi kwaye iluncedo ngakumbi kwiimeko apho izixhobo ezininzi zabelana ngetshaneli enye kwaye zifuna ukunxibelelana. Kukho iindlela ezimbini ezisisiseko ze-aloha: i-aloha ecocekileyo kunye ne-slotted aloha. Umahluko omkhulu phakathi kweentlobo zombini ze-aloha zichazwe ngezantsi.

1. UAloha onyulu:

I-aloha ecocekileyo yile ifomu yokuqala ye-Carrier Sense Multiple Access (CSMA) protocol kwaye yindlela elula ye-aloha. I-aloha ecocekileyo iyakuvumela nasiphi na isixhobo yabelana ngesitishi ngokulinganayo, oko kuthetha ukuba Izixhobo zingathumela nanini na. Nangona kunjalo, oku kuthetha ukuba izixhobo zinokusasaza ngaxeshanye, ezinokubangela ukungqubana.

2. Slotted Aloha:

I-slotted aloha yinguqulelo ephuculweyo ye-aloha esulungekileyo, eyahlula ixesha kwiindawo zokubeka ixesha okanye izithuba. Ukuhanjiswa kucwangciswe kwezi ndawo zokubeka, ezinciphisa amathuba okungqubana kunye nokwandisa ukusebenza kwenkqubo. Slotted aloha idla ngokusetyenziswa kwiinkqubo zothungelwano lwesathelayithi.

Isishwankathelo, umahluko omkhulu phakathi kwe-aloha esulungekileyo kunye ne-slotted aloha yile:

  • I-Aloha ecocekileyo ivumela nasiphi na isixhobo ukuba sabelane ngesitishi ngokulinganayo, oku kuthetha ukuba izixhobo zinokuhamba nangaliphi na ixesha.
  • I-aloha ebekiweyo yahlula ixesha libe zizinto zokubeka ixesha okanye izikhewu, ukunciphisa amathuba okungqubana nokwandisa ukusebenza kakuhle kwenkqubo.

Ukuqukumbela, zombini iintlobo ze-aloha zihlala ziluncedo kwiimeko ezahlukeneyo kwaye zibalulekile kunxibelelwano kunye nokwabelana ngokufikelela kuthungelwano lwengingqi. Ngoku ekubeni uwazi umahluko phakathi kwe-aloha esulungekileyo kunye ne-slotted aloha, unokukhetha eyona ifanele iimfuno zakho.
