Ukushintsha Amandla

Umthamo wokushintsha weswishi, owaziwa nangokuthi umkhawulokudonsa ongemuva noma umkhawulokudonsa oshintshayo, inani eliphakeme ledatha elingasingathwa phakathi kwephrosesa yesixhumi esibonakalayo noma ikhadi lesixhumi esibonakalayo kanye nebhasi ledatha.Umthamo wokushintshanisa ubonisa isamba somthamo wokushintshaniswa kwedatha weswishi, futhi iyunithi yi-Gbps.Amandla okushintshanisa okushintsha okujwayelekile asukela ku-Gbps ambalwa ukuya kumakhulu ama-Gbps.Ukuphakama komthamo wokushintsha weswishi, amandla okucubungula idatha aqina, kodwa ayanda izindleko zokuklama.

 Izinga lokudlulisela iphakethe

Izinga lokudlulisela iphakethe leswishi libonisa ubukhulu bekhono leswishi lokudlulisela phambili amaphakethe.Iyunithi ngokuvamile i-bps, futhi izinga lokudlulisela iphakethe lamaswishi avamile lisukela emashumini e-Kpps ukuya kumakhulu e-Mpps.Izinga lokudlulisela iphakethe lisho ukuthi zingaki izigidi zamaphakethe edatha (Mpps) iswishi engawadlulisela ngomzuzwana, okungukuthi, inani lamaphakethe wedatha iswishi engawadlulisela ngesikhathi esifanayo.Izinga lokudlulisela iphakethe libonisa amandla okushintsha amayunithi amaphakethe wedatha.

Eqinisweni, inkomba ebalulekile enquma izinga lokudlulisela iphakethe umkhawulokudonsa ongemuva weswishi.Ukuphakama komkhawulokudonsa we-backplane weswishi, amandla okucubungula idatha anamandla, okungukuthi, izinga lokudlulisela iphakethe liphezulu.

I-Ethernet Ring

Indandatho ye-Ethernet (evame ukubizwa ngokuthi inethiwekhi eyindandatho) iyi-topology eyindandatho ehlanganisa iqembu lamanodi e-Ethernet ahambisana ne-IEEE 802.1, inodi ngayinye ixhumana namanye amanodi amabili ngembobo yokukhala esekelwe ku-802.3 Media Access Control (MAC) I-Ethernet MAC ingakwazi iphathwe obunye ubuchwepheshe bongqimba lwesevisi (obufana ne-SDHVC, i-Ethernet pseudowire ye-MPLS, njll.), futhi wonke ama-node angaxhumana ngokuqondile noma ngokungaqondile.
