Kungani ukwabelana ngamafayela nge-VPN kuzwakala kunensayo: ukuhamba nokubuya, hhayi i-Mbps

Ukuvula ifolda eyabiwe nge-VPN nokulinda ngesikhathi uhlu lwemikhombandlela ludonsa kancane kuyisipiliyoni esijwayelekile, futhi umcabango wokuqala ukusola i-bandwidth. Ngokuvamile isixhumanisi sicishe sibe ngasihlala. Iphrothokholi ichitha isikhathi ilinde izimpendulo, futhi ukulinda ngakunye kubiza uhambo olugcwele lokuhamba nokubuya i-LAN engakaze ibale. Lungisa isimo somsebenzi, futhi ukwabelana kuyaphinda kusebenze.

Ikhophi yomsebenzi ekude inesimo esingalungile

I-SMB ivula amafayela, ifunda idatha yemetha futhi iqinisekisa ekushintshisaneni okuningi okuncane. Ikhophi yomsebenzi yokulawula izinguqulo kudrayivu exhunyiwe icabanga ukubambezeleka kwesistimu yamafayela yasendaweni futhi ifunda amafayela amaningi amancane. Isizindalwazi sedeskithophu sidonsa amakhasi ngesikhathi umsebenzisi esebenza. Ngakunye kwalokhu kwenza ukubambezeleka kube yisiphindaphindi, ngoba izindleko zikhula ngenani lokushintshisana okwenziwa umsebenzi; ngakho umhubhe we-40 ms wenza amakhulu ambalwa emisebenzi abe yimizuzwana embalwa. Ubukhulu bomthwalo cishe abunandaba kulezo zibalo.

Izindleko zokubethela ziyingxenye encane; ukulahlekelwa kubi kakhulu, ngoba ukudluliswa kabusha okukodwa kanye newindi lokuminyana eliwe phansi kubiza kakhulu kunamabhayithi ahilelekile.

Bala ukuhamba nokubuya ngaphambi kwamamegabhayithi

Linganisa ukubambezeleka ngaphambi kokuthenga umthamo. I-ping eyodwa ikutshela ukuthi ukushintshisana ngakunye kukhokha ini.

ping -c 10 fileserver.example.net

Isifinyezo sinikeza isikhathi esincane, esimaphakathi nesikhulu sokuhamba nokubuya, futhi ukusabalala kubalulekile njengokumaphakathi. Phindaphinda okumaphakathi ngenani lokushintshisana okwenziwa uhlu lwemikhombandlela, bese uqhathanisa nesikhathi osibonayo ngempela. Uma ifayela elilodwa elikhulu lidluliswa ngokushesha ngesikhathi ukuphequlula kuhamba kancane, umkhawulo ukubambezeleka nenani lezicelo. Ukwengeza umthamo ophindwe kayishumi kusixhumanisi esingakaze sigcwale akushintshi lutho neze.

Hambisa umsebenzi, hhayi amabhayithi

Shintsha lapho umsebenzi kwenzeka khona esikhundleni sokukhokhela ipayipi elibanzi. Sebenza isitoreji esikhundleni sokufaka, futhi kopisha ngobuningi ngethuluzi elithumela umehluko kuphela.

rsync -av --info=progress2 ./project/ [email protected]:/srv/share/project/

Ukwenza isitoreji sisebenze, njengoba kwenza i-hgweb noma i-Git ekude, kuvumela iklayenti ukuba sisebenze kukhophi yasendaweni ukuze izingcingo zayo zesistimu yamafayela zingawi umhubhe neze. I-rsync ihamba izinhlangothi zombili futhi ithumela amabhulokhi ashintshile, isusa iningi lokushintshisana okukhokhwa ikhophi elula. Isizindalwazi sedeskithophu kufanele sibe senjinini yohlangothi lweseva futhi iklayenti lincishiswe libe yisixhumi esibonakalayo, noma iklayenti lonke lisebenza kusibungazwa sangaphakathi. Inketho ngayinye ishintsha ukuthi iphrothokholi ibhekana nokubambezeleka okungakanani, futhi lokho kuyiphuzu.

Ukuma eduze kosayizi ofanayo wuphawu lwe-MTU

Ukudluliswa okukhulu okuma ngemuva kwedatha ecishe ilingane, ngesikhathi i-ping namakhasi amancane esebenza, kukhombisa usayizi wephakethe hhayi i-bandwidth.

ping -M do -s 1400 -c 3 fileserver.example.net

Ukuhlolwa okuphumelelayo kusho ukuthi iphakethe le-IP lamabhayithi angu-1428 liwela indlela lingahlukaniswanga, ngoba izihloko ze-ICMP ne-IP zengeza amabhayithi angu-28. Ukwehluleka ngefulegi lokuvimbela ukuhlukanisa kusikisela ukuthi i-MTU esebenzisekayo yomhubhe incane kunalokho iseva ekucabangayo. Iseva ethumela amabhafa angu-9000 endleleni engu-1500 iphoqa ukuhlukanisa noma ukulahla, futhi ukutholakala kwe-MTU yendlela kungahluleka buthule lapho i-ICMP ihlungiwe. Yehlisa i-MTU yomhubhe, nika amandla mssfix ku-OpenVPN, noma nciphisa amabhafa eseva, bese uphinda ugijime ukudluliswa okufanayo ukuze uqinisekise.

Linganisa igebe elibalulekile

Gijima umsebenzi ofanayo ngezindlela ezintathu lapho inqubomgomo ivuma khona: kwasendaweni, ngomhubhe nangendlela eqondile ye-inthanethi. Ngakunye, bhala isikhathi sokuhamba nokubuya, izinga lomfudlana omkhulu owodwa, nokuthi uhlu lwemikhombandlela noma ukuvula uhlelo kuthatha isikhathi esingakanani. Ukuqhathanisa ukugijima kwasendaweni nokugijima ngomhubhe kubonisa ukuthi izindleko ziphi ezibusayo. Ikhophi ephela kancane isikisela inkinga yejubane noma yokubambezeleka, kuyilapho ikhophi efa endaweni engaguquguquki isikisela usayizi wephakethe noma idivayisi egcina isimo endleleni.

Uma kudonsa kuphela amamegabhayithi okuqala, bheka ukuqinisekiswa nedatha yemetha; uma konke kudonsa kancane, bheka umthamo nokulahlekelwa. Lungisa imbangela efanelayo, futhi yeka ukulindela ukuthi isixhumanisi se-WAN siziphatha njengentambo ye-LAN.
