Waxaa jira noocyo badan oo ah furayaasha suuqa, laakiin sidoo kale waxaa jira kala duwanaansho shaqo oo kala duwan, iyo sifooyinka ugu muhiimsan waa kala duwan yihiin.Waxa loo qaybin karaa iyadoo loo eegayo dareenka ballaadhan iyo cabbirka codsiga:
1)Marka hore, dareen ballaadhan, furayaasha shabakadaha ayaa loo qaybin karaalaba qaybood: kala saar WAN-ga iyo furayaasha LAN.
Meesha ugu muhiimsan ee furayaasha WAN-ga lagu isticmaalo isgaarsiintu waa Waxay siinayaan dadka isticmaala aalad aasaasi ah oo isgaarsiineed oo dabooli karta baahida isticmaalayaasha badan.Heerarka gudbinta isticmaaleyaasha kala duwan ma faragelin doonaan midba midka kale.
Shidayaasha LAN, tani waxay aad diirada u saaran tahay LAN-ka, kaas oo loo isticmaalo in lagu xidho aalado badan oo terminal ah, sida in la dhiso qayb isku mid ah oo loogu talagalay PC iyo daabacaha shabakada.
Marka la eego warbaahinta gudbinta iyo xawaaraha gudbinta, waxaa loo qaybin karaa furayaasha Ethernet, furayaasha Ethernet degdega ah, giraanta Ethernet-ka ee gigabit, furayaasha FDDI, furayaasha ATM-ka, iyo furayaasha calaamada.
2)Marka la eego cabbirka iyo codsiga, waxa loo qaybin karaa beddeleyaasha heer-shirkadeed, beddelayaal heer-waaxeed, iyo beddelayaal koox shaqo.Heerarka soosaarayaasha kala duwani si buuxda uma wada socdaan.Guud ahaan, dareemaha heerka ganacsigu waa nooca rack-ka, halka furayaasha waaxdu ay noqon karaan nooca rack-ka (oo leh boosas yar) ama qaabayn go'an, halka dareemaha heerka-shaqadu ay yihiin noocyo habayn go'an (oo leh hawlo fudud).Dhanka kale, marka loo eego cabbirka codsiga, sida beddelka laf-dhabarta, furayaasha taageera codsiyada ganacsiga waaweyn ee leh in ka badan 500 dhibcood macluumaadka waa furayaasha heerka ganacsiga, iyo furayaasha taageera shirkadaha dhexdhexaadka ah ee ka yar 300 oo macluumaad. Dhibcuhu waa beddelayaal heer waaxeed ah, furayaasha taageera in ka yar 100 dhibcood ee macluumaadka waa beddelayaal heer kooxeed shaqo.
Kor ku xusan waa sharaxaadda "Classification of Switches" ay keeneenShenzhen HDV Optoelectronics Technology Co., Ltd.Ku soo DHAWOOWna waydiinooc kasta oo ah alaabta qalabka isgaarsiinta indhaha.
