I-Mylinking™ Network Packet Brokers isekela i-Network Traffic Dynamic Load Balancing:Ibhalansi yomthwalo I-algorithm ye-Hash kanye ne-algorithm yokwabelana ngesisindo eseseshini ngokuya ngezici zesendlalelo se-L2-L7 ukuze kuqinisekiswe ukuthi ithrafikhi ephumayo yembobo iyaguquguquka yokulinganisa umthwalo. Futhi
I-Mylinking™ Network Packet Brokers isekela Ukutholwa Kwethrafikhi Yesikhathi Sangempela:Isekelwe imithombo ye-"Capture Physical Port (Data Acquisition)", "I-Packet Feature Description Field (L2 – L7)", nolunye ulwazi ukuze kuchazwe isihlungi sethrafikhi esivumelana nezimo, ukuze kuthathwe idatha yenethiwekhi yokuthwebula ngesikhathi sangempela sokutholwa kwesikhundla esihlukile, futhi izogcinwa idatha yesikhathi sangempela ngemuva kokuthwebula nokutholwa kudivayisi yokudawuniloda le mishini yokuhlaziya ejulile noma isebenzise izici zokuhlaziya ezijulile.
Ungase udinge ukwazi ukuthi yini i-OSI Model 7 Layers?
Ngaphambi kokuthi singene kumodeli ye-OSI, sidinga ukuqonda amagama athile ayisisekelo enethiwekhi ukuze siqhubekisele ingxoxo elandelayo.
Ama-Nodes
I-node inodi yinoma iyiphi idivayisi ye-elekthronikhi ebonakalayo exhunywe kunethiwekhi, njengekhompyutha, iphrinta, irutha, njll. Amanodi angaxhunywa enye nenye ukuze akhe inethiwekhi.
Isixhumanisi
Isixhumanisi ukuxhumana okungokoqobo noma okunengqondo okuxhumayo amanodi kunethiwekhi, okungenzeka kunezintambo (njenge-Ethernet) noma okungenantambo (okufana ne-WiFi) futhi kungaba iphoyinti-kuya-iphuzu noma i-multipoint.
Iphrothokholi
Iphrothokholi ingumthetho wamanodi amabili kunethiwekhi ukushintshanisa idatha. Le mithetho ichaza i-syntax, semantics, nokuvumelanisa kokudluliswa kwedatha.
Inethiwekhi
Inethiwekhi isho iqoqo lamadivayisi, njengamakhompyutha, amaphrinta, aklanyelwe ukwabelana ngedatha.
I-Topology
I-Topology ichaza ukuthi amanodi nezixhumanisi kumiswa kanjani kunethiwekhi futhi iyisici esibalulekile sokwakheka kwenethiwekhi.
Iyini imodeli ye-OSI?
Imodeli ye-OSI (Open Systems Interconnection) ichazwa yi-International Organization for Standardization (ISO) futhi ihlukanisa amanethiwekhi amakhompiyutha abe amazinga ayisikhombisa ukusiza ukuxhumana phakathi kwamasistimu ahlukene. Imodeli ye-OSI inikeza ukwakheka okujwayelekile kwesakhiwo senethiwekhi, ukuze amadivayisi avela kubakhiqizi abahlukene akwazi ukuxhumana.
Izendlalelo eziyisikhombisa zemodeli ye-OSI
1. Ungqimba Lomzimba
Inesibopho sokudlulisa ukusakaza kwebhithi eluhlaza, ichaza izici zemidiya ebonakalayo njengamakhebuli namasignali angenantambo. Idatha idluliselwa ngamabhithi kulesi sendlalelo.
2. Isendlalelo Sesixhumanisi Sedatha
Amafreyimu edatha adluliselwa ngesignali ephathekayo futhi anesibopho sokutholwa kwamaphutha nokulawula ukugeleza. Idatha icutshungulwa ngozimele.
3. Isendlalelo senethiwekhi
Inesibopho sokuthutha amaphakethe phakathi kwamanethiwekhi amabili noma ngaphezulu, ukuphatha umzila kanye namakheli anengqondo. Idatha icutshungulwa ngamaphakethe.
4. Uhlaka Lwezokuthutha
Inikeza ukulethwa kwedatha ekupheleni kuya ekupheleni, iqinisekisa ubuqotho bedatha nokulandelana, okuhlanganisa iphrothokholi eqondisiwe yoxhumano lwe-TCP kanye nephrothokholi engaxhunywanga ye-UDP. Idatha ikumayunithi amasegimenti (TCP) noma ama-datagram (UDP).
5. Isendlalelo Seseshini
Lawula amaseshini phakathi kwezicelo, onesibopho sokusungulwa kweseshini, ukugcinwa, kanye nokunqanyulwa.
6. Isendlalelo Sesethulo
Bamba ukuguqulwa kwefomethi yedatha, ukubhala ngekhodi kwezinhlamvu, kanye nokubethela kwedatha ukuze uqinisekise ukuthi idatha ingasetshenziswa ngendlela efanele isendlalelo sohlelo lokusebenza.
7. Uhlelo Lokusebenza
Ihlinzeka abasebenzisi ngamasevisi enethiwekhi aqondile, okuhlanganisa izinhlelo zokusebenza namasevisi ahlukahlukene, njenge-HTTP, i-FTP, i-SMTP, njll.
Inhloso yesendlalelo ngasinye semodeli ye-OSI kanye nezinkinga zayo ezingaba khona

Imodeli ye-TCP/IP kanye nomehluko wemodeli ye-OSI
Nakuba imodeli ye-OSI iyizinga lokuxhumana kwenethiwekhi, imodeli ye-TCP/IP iyindinganiso esetshenziswa kabanzi yenethiwekhi. Imodeli ye-TCP/IP isebenzisa ukwakheka kwe-hierarchical, kodwa inezendlalelo ezine kuphela (usendlalelo sohlelo lokusebenza, isendlalelo sezokuthutha, isendlalelo senethiwekhi, nesendlalelo sesixhumanisi), ezihambelana nezinye ngale ndlela elandelayo:
Isendlalelo sohlelo lokusebenza lwe-OSI <--> TCP/IP isendlalelo sohlelo lokusebenza
Isendlalelo sezokuthutha se-OSI <--> TCP/IP isendlalelo sokuthutha
Isendlalelo senethiwekhi ye-OSI <--> Isendlalelo senethiwekhi ye-TCP/IP
Isendlalelo sesixhumanisi sedatha ye-OSI nesendlalelo esibonakalayo <--> Isendlalelo sesixhumanisi se-TCP/IP
Ngakho, imodeli ye-OSI enezingqimba eziyisikhombisa inikeza isiqondiso esibalulekile sokusebenzisana kwamadivayisi enethiwekhi nezinhlelo ngokuhlukanisa ngokucacile zonke izici zokuxhumana kwenethiwekhi. Ukuqonda le modeli akusizi nje kuphela abalawuli benethiwekhi ukuxazulula izinkinga, kodwa futhi kubeka isisekelo socwaningo kanye nocwaningo olujulile lobuchwepheshe benethiwekhi. Ngethemba ukuthi ngalesi singeniso, ungaqonda futhi usebenzise imodeli ye-OSI ngokujulile.
