Kukula kwa phukusi la TCP laling'ono kumakhudza ntchito yovuta
Mawotchi opititsa patsogolo (MTU) ndi kukula kwake kwa chida chimodzi cha deta chojambulira pa digito chomwe chikhoza kulengezedwa pa intaneti. Ukulu wa MTU ndi malo enieni a mawonekedwe a mawonekedwe ndipo nthawi zambiri amayesedwa ndi bytes . Mwachitsanzo, MTU ya Ethernet , ndi 1500 bytes. Mitundu ina yamagetsi, monga mphete zapachizindikiro, imakhala ndi ma MTU akuluakulu, ndipo ma intaneti ali ndi ma MTU ang'onoting'ono, koma mtengo uli wokhazikika pa zipangizo zamtundu uliwonse.
MTU vs. Maximum TCP Pakiti ya Pakiti
Mapulogalamu apamwamba apamwamba monga TCP / IP akhoza kukhazikitsidwa ndi kukula kwa paketi phukusi, yomwe ndiyomwe imakhala yosasunthika pa MTU yomwe pamakhala TCP / IP. Tsoka ilo, mafoni ambiri ogwiritsira ntchito makina amagwiritsira ntchito mawuwo mosiyana. Pa maulendo onse awiri apanyumba ndi makina othandizira masewera a Xbox Live, mwachitsanzo, chizindikiro chomwe chimatchedwa MTU ndikulitsa kukula kwa pakiti ya TCP osati ma MTU.
Mu Microsoft Windows, kukula kwakukulu kwa pakiti ya ma protocol monga TCP ikhoza kuikidwa mu Registry. Ngati mtengowu wasweka kwambiri, mitsinje yamtundu wa magetsi imasweka n'kukhala ndi mapepala ang'onoang'ono, omwe amakhudza kwambiri ntchito. Mwachitsanzo, Xbox Live, imafuna kufunika kwa kukula kwa paketi kuti ikhale 1365 bytes. Ngati kukula kwa phukusi la TCP likakhala lokwezeka kwambiri, limaposa MTU kuti liwonongeke ntchitoyo ndipo limafuna kuti phukusi ligawidwe likhale lochepa. Makompyuta a Microsoft Windows osasintha mpaka kukula kwa pakiti ya 1500 bytes kwa mauthenga a broadband ndi 576 bytes for connections -up connection.
Mavuto Okhudzana ndi MTU
Malingaliro, kuchepa kwa kukula kwa paketi ya PCK ndi 64K (65,525 bytes). Limeneli ndi lalikulu kwambiri kuposa momwe mungagwiritsire ntchito chifukwa zigawo zofalitsa zimakhala ndi zazikulu kwambiri. MTU ya Ethernet ya 1500 byte imachepetsa kukula kwa mapaketi omwe amayendayenda. Kutumiza pakiti yomwe ili yaikulu kusiyana ndi mawindo opatsirana amtundu wa Ethernet amatchedwa jabbering. Jabber ikhoza kudziwika ndi kutetezedwa. Ngati simunasokonezedwe, jabbering ikhoza kusokoneza intaneti. Kawirikawiri, jabber imadziwika ndi maulendo obwereza kapena makina opangidwa ndi intaneti omwe apangidwa kuti achite. Njira yosavuta yothetsera jabber ndiyoyikitsa kukula kwake kwa pakiti ya TCP osaposa 1500 bytes.
Mavuto ogwira ntchito angayambenso ngati TCP yayikulu yotumizira mauthenga pa routiyumu yapamwamba yamtunda ikusiyana ndi malingaliro pazipangizo zomwe zimagwirizanitsidwa nazo.
