I-Mylinking™ Network Packet Brokers isekela i-Network Traffic Dynamic Load Balancing:I-algorithm yebhalansi yomthwalo we-Hash kanye ne-algorithm yokwabelana ngesisindo esekelwe kwiseshini ngokwezici zesendlalelo se-L2-L7 ukuqinisekisa ukuthi i-port output traffic dynamic yokulinganisela umthwalo.
Abathengisi Bephakethe Lenethiwekhi ye-Mylinking™ basekela Ukutholwa Kwethrafikhi Yesikhathi Sangempela:Kusekelwe imithombo ethi "Capture Physical Port (Data Acquisition)", "Packet Feature Description Field (L2 – L7)", kanye nolunye ulwazi lokuchaza isihlungi sethrafikhi esiguquguqukayo, ukuze kuthathwe idatha yenethiwekhi ngesikhathi sangempela yokutholwa kwezindawo ezahlukene, futhi kuzogcinwa idatha yesikhathi sangempela ngemva kokubanjwa nokutholwa kudivayisi ukuze kulandwe ukuhlaziywa kochwepheshe bokusebenza okwengeziwe noma kusetshenziswe izici zayo zokuxilonga zale mishini ukuze kuhlaziywe ngokubonakalayo okujulile.
Kungase kudingeke wazi ukuthi iyini i-OSI Model 7 Layers?
Ngaphambi kokuthi singene kwimodeli ye-OSI, sidinga ukuqonda amagama athile ayisisekelo okuxhumana ukuze kube lula ingxoxo elandelayo.
Ama-Node
I-node iyinoma iyiphi idivayisi kagesi exhunywe kunethiwekhi, njengekhompyutha, iphrinta, i-router, njll. Ama-node angaxhunyaniswa ukuze akhe inethiwekhi.
Isixhumanisi
Isixhumanisi siwuxhumano olungokoqobo noma olunengqondo oluxhumanisa ama-node kunethiwekhi, angase abe nezintambo (njenge-Ethernet) noma angenantambo (njenge-WiFi) futhi angaba yi-point-to-point noma ama-multipoint.
Iphrothokholi
Iphrothokholi iwumthetho wama-node amabili kunethiwekhi ukushintshanisa idatha. Le mithetho ichaza i-syntax, i-semantics, kanye nokuvumelanisa ukudluliswa kwedatha.
Inethiwekhi
Inethiwekhi ibhekisela eqoqweni lamadivayisi, njengamakhompyutha, amaphrinta, aklanyelwe ukwabelana ngedatha.
I-Topology
I-Topology ichaza ukuthi ama-node nezixhumanisi zihlelwa kanjani kunethiwekhi futhi iyisici esibalulekile sesakhiwo senethiwekhi.
Iyini imodeli ye-OSI?
Imodeli ye-OSI (Open Systems Interconnection) ichazwa yi-International Organisation for Standardization (ISO) futhi ihlukanisa amanethiwekhi ekhompyutha abe amazinga ayisikhombisa ukusiza ukuxhumana phakathi kwezinhlelo ezahlukene. Imodeli ye-OSI inikeza ukwakheka okujwayelekile kwesakhiwo senethiwekhi, ukuze amadivayisi avela kubakhiqizi abahlukene akwazi ukuxhumana.

3. Isendlalelo Senethiwekhi
Inesibopho sokuthutha amaphakethe phakathi kwamanethiwekhi amabili noma ngaphezulu, ukuphatha umzila kanye nokuxhumana okunengqondo. Idatha icutshungulwa kumaphakethe.
4. Isendlalelo Sokuthutha
Ihlinzeka ngokulethwa kwedatha kusukela ekuqaleni kuya ekugcineni, iqinisekisa ubuqotho bedatha kanye nokulandelana kwayo, okuhlanganisa iphrothokholi eqondiswe ekuxhumekeni i-TCP kanye nephrothokholi engenakho ukuxhumana i-UDP. Idatha itholakala kumayunithi ezingxenye (i-TCP) noma ama-datagram (i-UDP).
5. Isendlalelo Seseshini
Phatha izikhathi phakathi kwezicelo, onesibopho sokusungulwa kwezikhathi, ukulungiswa, kanye nokuphela kwazo.
6. Isendlalelo Sesethulo
Phatha ukuguqulwa kwefomethi yedatha, ukufaka ikhodi yezinhlamvu, kanye nokubethela idatha ukuqinisekisa ukuthi idatha ingasetshenziswa kahle yisendlalelo sohlelo lokusebenza.
7. Isendlalelo Sohlelo Lokusebenza
Inikeza abasebenzisi izinsizakalo zenethiwekhi eziqondile, okuhlanganisa izinhlelo zokusebenza nezinsizakalo ezahlukahlukene, njenge-HTTP, i-FTP, i-SMTP, njll.

Umehluko phakathi kwemodeli ye-TCP/IP kanye nemodeli ye-OSI
Nakuba imodeli ye-OSI iyindinganiso yokuxhumana kwenethiwekhi yethiyori, imodeli ye-TCP/IP iyindinganiso yenethiwekhi esetshenziswa kabanzi. Imodeli ye-TCP/IP isebenzisa isakhiwo esilandelanayo, kodwa inezendlalelo ezine kuphela (izendlalelo zohlelo lokusebenza, isendlalelo sokuthutha, isendlalelo senethiwekhi, kanye nesendlalelo sesixhumanisi), ezihambisana kanje:
Isendlalelo sohlelo lwe-OSI <--> Isendlalelo sohlelo lwe-TCP/IP
Isendlalelo sokuthutha se-OSI <--> Isendlalelo sokuthutha se-TCP/IP
Isendlalelo senethiwekhi ye-OSI <--> Isendlalelo senethiwekhi ye-TCP/IP
Isendlalelo sesixhumanisi sedatha ye-OSI kanye nesendlalelo esibonakalayo <--> Isendlalelo sesixhumanisi se-TCP/IP
Ngakho-ke, imodeli ye-OSI enezingqimba eziyisikhombisa inikeza isiqondiso esibalulekile sokusebenzisana kwamadivayisi nezinhlelo zenethiwekhi ngokuhlukanisa ngokucacile zonke izici zokuxhumana kwenethiwekhi. Ukuqonda le modeli akusizi nje kuphela abaphathi benethiwekhi ukuxazulula izinkinga, kodwa futhi kubeka isisekelo socwaningo kanye nocwaningo olujulile lobuchwepheshe benethiwekhi. Ngithemba ukuthi ngalesi singeniso, ungaqonda futhi usebenzise imodeli ye-OSI ngokujulile.
