Awood beddelidda

Awoodda beddelka ee dareemaha, oo sidoo kale loo yaqaan bandwidth-dhabarka ama wareejinta bandwidth, waa xaddiga ugu badan ee xogta lagu maarayn karo inta u dhaxaysa processor-ka is-beddelka ama kaarka interface-ka iyo baska xogta. Awoodda sarifku waxay muujinaysaa wadarta guud ee awoodda beddelka xogta ee beddelka, cutubkuna waa Gbps. Awoodda beddelka beddelka beddelka guud waxay u dhaxaysaa dhowr Gbps ilaa boqolaal Gbps. Mar kasta oo ay sareeyso awoodda beddelka ee beddelka, way sii xoogaysanaysaa awoodda lagu socodsiiyo xogta, laakiin waxa sarreeya kharashka naqshadaynta.

 Heerka gudbinta baakadka

Heerka gudbinta baakidhku waxa uu tilmaamayaa cabbirka awoodda baakadaha u gudbinta baakadaha. Unuggu guud ahaan waa bps, iyo heerka gudbinta baakadda ee beddelka guud wuxuu u dhexeeyaa tobanaan Kpps ilaa boqollaal Mpps. Heerka gudbinta baakidhku waxa uu tilmaamayaa inta milyan ee baakidhyada xogta (Mpps) ee beddeluhu u gudbin karo ilbiriqsi kasta, taas oo ah, tirada baakadaha xogta ee daaruhu isku mar gudbin karo. Heerka gudbinta baakidhku waxa uu ka tarjumayaa awoodda beddelka beddelka ee cutubyada xidhmooyinka xogta.

Dhab ahaantii, tilmaame muhiim ah oo go'aaminaya heerka gudbinta baakidhku waa xajmiga dhabarka ee wareejinta. Mar kasta oo ay sare u kacdo baaxadda xajmiyeedka diyaaradda dhabarka ee beddelka, waxa sii xoogaysanaya awoodda lagu socodsiinayo xogta, taas oo ah, waxa sarreeya heerka gudbinta baakidhku.

Giraanta Ethernet

Giraanta Ethernet (oo loo yaqaanno network giraanta) waa topology giraan ah oo ka kooban koox ka kooban IEEE 802.1 qanjidhada Ethernet u hoggaansan, nood kasta oo la xidhiidha labada nood ee kale iyada oo loo marayo 802.3 Media Access Control (MAC) ee ku salaysan giraanta Ethernet MAC oo ay wataan tignoolajiyada lakabka adeegga kale (sida SDHVC, Ethernet pseudowire ee MPLS, iwm.), iyo dhammaan qanjidhada ayaa si toos ah ama si dadban ula xiriiri kara.
