I-Switch (Switch) isho ukuthi “switch” futhi iyidivayisi yenethiwekhi esetshenziselwa ukudlulisa isignali kagesi (optical). Inganikeza indlela ekhethekile yesignali kagesi yanoma yimaphi ama-node amabili enethiwekhi yeswitch yokufinyelela. Ama-switch avame kakhulu ama-switch e-Ethernet. Amanye avamile ama-switch ezwi ocingweni, ama-fibre switch njalo njalo.
Imisebenzi eyinhloko yeswishi ifaka phakathi ikheli elibonakalayo, i-topology yenethiwekhi, ukuhlola amaphutha, ukulandelana kohlaka, kanye nokulawula ukugeleza. Iswishi futhi ineminye imisebenzi emisha, njengokusekela i-VLAN (Virtual Local Area Network), ukwesekwa kokuhlanganiswa kwezixhumanisi, kanti eminye inomsebenzi we-firewall.
1. Njengezikhumulo, amaswishi ahlinzeka ngamachweba amaningi okufaka izintambo, okuvumela ukufakwa kwezintambo endaweni yenkanyezi.
2. Njengeziphindaphindo, ama-hub, namabhuloho, iswishi iphinda ivuselele isignali kagesi eyisikwele engaphambukile njengoba idlulisela ozimele phambili.
3. Njengamabhuloho, amaswishi asebenzisa indlela efanayo yokudlulisela noma yokuhlunga kuzo zonke izimbobo.
4. Njengebhuloho, iswishi ihlukanisa inethiwekhi yendawo ibe yizizinda eziningi zokushayisana, ngayinye ene-bandwidth ezimele, ngaleyo ndlela ithuthukisa kakhulu i-bandwidth yenethiwekhi yendawo.
5.Ngaphezu kwemisebenzi yamabhuloho, ama-hub, kanye nama-repeater, amaswishi anikeza izici ezithuthukisiwe kakhulu njengamanethiwekhi endawo abonakalayo (ama-VLAN) kanye nokusebenza okuphezulu.
