Usayizi wepakethe we-TCP ophansi uthinta ukusebenza kabi
I-unit maximum yokudlulisela (MTU) yisayizi esiphezulu yedatha eyodwa yedatha yokuxhumana yedijithali engadluliselwa phezu kwenethiwekhi. Ubukhulu be-MTU buyimpahla ehambelanayo yesikhombimsebenzisi sezinhlelo zomzimba futhi ngokuvamile kulinganiswa ngama- bytes . I-MTU ye- Ethernet , ngokwesibonelo, i-bytes ezingu-1500. Ezinye izinhlobo zamanethiwekhi, njengezinkinobho ze- token , zinama-MTU amakhulu, kanti amanye amanethiwekhi anama-MTU amancane, kodwa inani lilungiselwe ubuchwepheshe bomzimba ngamunye.
Usayizi we-MTU vs. Maximum TCP Packet
Izindlela zokuxhumana zenethiwekhi eziphakeme efana ne- TCP / IP zingalungiswa ngobukhulu bepakethe, okuyi-parameter emele i-MTU engokwenyama phezu kwe-TCP / IP. Ngeshwa, amadivaysi amaningi enethiwekhi asebenzisa amagama ngokungafani. Kuzo zombili zomgwaqo we-broadband ekhaya ne-Xbox Live-consoles game-consoles, isibonelo, i-parameter ebizwa ngokuthi i-MTU, empeleni, isayizi yepakethe ye-TCP hhayi i-MTU ngokomzimba.
Ku-Microsoft Windows, ubukhulu bomphakethe usayizi wezinhlelo ezifana ne-TCP zingasethwa kwi-Registry. Uma le nzuzo isethwe kakhulu, imifudlana yethrafikhi yenethiwekhi ihlukaniswa ibe yinani elikhulu kakhulu lamaphakethe amancane, okulimaza kakhulu ukusebenza. I-Xbox Live, isibonelo, idinga ukubaluleka kokuphakama kwepakethe kube okungenani ama-bytes angu-1365. Uma ubukhulu bepakethe ye-TCP bubekwe phezulu, budlula i-MTU engokwenyama yenethiwekhi futhi bulimaza ukusebenza ngokudinga ukuthi iphakethe ngalinye lihlukaniswe libe elincane-inqubo yaziwa ngokuthi ukuhlukaniswa. Amakhompiyutha e-Microsoft Windows ahluleka ukuphakama ngobukhulu bepakethe ye-1500 byte zokuxhumeka kwe-broadband kanye no-576 bytes zokuxhuma.
Izinkinga ezihlobene ne-MTU
Ngokwalokho, ukukhawulelwa kwesayizi wepakethe ye-TCP kungama-64K (65,525 bytes). Lo mkhawulo ukhulu kakhulu kunokuba uzoke usebenzise ngoba izendlalelo zokudlulisa zinamazinga aphansi kakhulu. I-MTU ye-Ethernet yama-bytes angu-1500 iyalinganisa ubukhulu bamaphakethe abhekene nayo. Ukuthumela iphakethe elikhulu kunewindi yokudlulisela e-Ethernet ibizwa ngokuthi i-jabbering. I-Jabber ingabonakala futhi ivinjelwe. Uma ungagxiliwe, ukuhlayalaza kungaphazamisa inethiwekhi. Ngokuvamile, i-jabber itholakala ngama-hubs okuphindaphindiwe noma izintambo zenethiwekhi ezenzelwe ukwenza kanjalo. Indlela elula yokuvimbela i-jabber ukusetha usayizi ophezulu wepakethe ye-TCP angabi ngaphezu kwama-bytes angu-1500.
Izinkinga zomsebenzi zingase zenzeke uma ukulungiswa okuphezulu kokudluliselwa kwe-TCP ku- router yasekhaya ebanzi kuncike ekusetshenzisweni kwamadivaysi ngamunye axhunywe kuyo.
