I-BranchCache yokwabelana ngamafayela nge-VPN: kusiza nini, akusizi nini

Othile eqenjini uthi ukwabelana ngamafayela nge-VPN kuhamba kancane, futhi isiphakamiso sokuqala sihlala siyi-cache. Ngaphambi kokwengeza i-BranchCache kumklamo wokufinyelela kude, hlukanisa isikhalo sibe ngesinye sezimo ezintathu: ukulandwa okuphindaphindiwe kokuqukethwe okungashintshi, ukulayisha, noma ukuphequlula okusinda kumethadatha kumafolda anezinkulungwane zokufakiwe. I-BranchCache ixazulula isimo sokuqala kokuqukethwe okusekelwayo futhi ayenzi lutho olusizayo kwezinye ezimbili. Lokho akusona isithiyo okufanele kugwenywe; yilokho ukuqhathanisa okufanele ukwenze ngaphambi kokuchitha iviki ekusetshenzisweni.

Ukusabelana okufanayo, izikhalo ezintathu ezihlukene

Ihhovisi legatsha lapho abantu abayisishiyagalombili bevula khona ividiyo yokuqeqesha efanayo engashintshi yiso leso simo okwakuklanyelwe sona lesi sici. Ukulandwa kokuqala kuwela i-WAN, okuqukethwe kugcinwa ku-cache eduze kwabafundi, futhi ukulandwa kwamuva kwefayela elifanayo elingashintshi kunikezwa ngokwasekhaya. Inzuzo ingokoqobo futhi incane: okuqukethwe okufanayo, okungashintshi, abafundi abaningi.

I-laptop elayisha ukuqoshwa okusha ngesixhumi sasekhaya yiso leso simo esihlukile. Akukho khophi egcinwe ku-cache ngaphambili yefayela elingakabi khona, ngakho ukulayisha kulandela indlela efanayo evinjelwe njalo. I-cache yokulanda ayikususi ukulayisha, futhi akukho kukhetha indawo okukushintshayo lokho.

Isimo sesithathu yiso lesi esidumelela abantu ngoba sibukeka njengenkinga yokulanda. Ukuvula uhlu oluqukethe izinkulungwane eziyishumi zamafayela, ukuluhlela nokufunda imethadatha kuwukugeleza kwemisebenzi emincane, hhayi ukudluliswa okuphindaphindiwe kwento eyodwa enkulu. Ukugcina imizimba yamafayela ku-cache akusizi lutho ekufakweni kuhlu.

I-cache esabalalisiwe: ichibi le-VPN akulona i-LAN yegatsha

Kumodi esabalalisiwe, amakhompyutha eklayenti abelana ngokuqukethwe okugcinwe ku-cache, futhi i-Microsoft ibhala leyo modi njengesebenza ngaphakathi kwesubneti eyodwa. Ichibi lamaklayenti e-VPN akulona isubneti ngalowo mqondo ngisho noma wonke amakheli abukeka elandelana: ukutholwa kontanga, ukufinyeleleka kweklayenti-kuya-klayenti kanye nemvume yokushintshana ngedatha ye-cache kuyimibuzo ehlukene, futhi umklamo ojwayelekile wokufinyelela kude uphendula yomithathu ngokuthi cha.

Ungenza ichibi liziphathe njenge-LAN yegatsha ngokuvumela ithrafikhi yeklayenti-kuya-klayenti, kodwa leso yisinqumo sokuphepha, hhayi isinqumo se-cache. Iningi lemiklamo yokufinyelela kude ihlukanisa amaklayenti elinye kwelinye ngenxa yokuthi i-laptop eyodwa ephukile ingafinyeleli elinye, futhi ukushintsha lokho kuhlukanisa nge-cache hit kuwukuhweba okubi ngaphandle uma ontanga sebethembekile futhi balingana.

Kumsebenzisi oyedwa ozulazulayo, imodi esabalalisiwe ayinamuntu wokwabelana naye. I-cache isengakwazi ukunikeza ukufunda okuphindaphindiwe kwalelo klayenti elilodwa, kodwa lokho kuyinzuzo ye-cache ohlangothini lweklayenti, hhayi inzuzo yendawo yegatsha, futhi kufanele kushiwo lokho ngaphambi kokuba othile alindele ukuthi ihhovisi lizoshesha.

I-cache esingathiwe: indawo inquma ukuthi iyasiza yini

I-cache esingathiwe ibeka i-cache eyabiwe kuseva, okuyimodi kuphela enengqondo phakathi kwamasubneti futhi okuyiyo kuphela esebenzayo lapho amaklayenti engakwazi ukukhuluma nawo. Umbuzo osheshayo uwukuthi leyoseva imi kuphi. I-cache esingathiwe efinyelelwa ngoxhumano olufanayo oluvinjelwe njengomthombo isuse amabhayithi, hhayi inkinga.

Yibeke eduze kwabafundi, yinikeze umnikazi, futhi linganisa idiski yayo yesethi yokusebenza hhayi yonke into eyabiwe. Microsoft Umbono jikelele we-BranchCache ichaza zombili izimodi nokuziphatha kweklayenti, kuhlanganise nengxenye abantu abayikhohlwayo: amaklayenti asaxhumana nomthombo ukuze athole imvume nolwazi lokuqukethwe ngaphambi kokusebenzisa idatha egcinwe ku-cache.

Ukusetshenziswa kungamadima amathathu ahlelwe ndawonye, hhayi ibhokisi elilodwa lokuhlola. Iseva yomthombo ishicilela ama-hashi okuqukethwe, i-cache esingathiwe iyasebenza futhi iyatholakala, futhi amaklayenti alungiselelwa ukuyisebenzisa. Ohlangothini lweseva lokho kuyabonakala ku-PowerShell:

Enable-BCHostedServer -RegisterSCP
Get-BCStatus | Select-Object BranchCacheIsEnabled, ClientMode, HostedCacheServerList

Kuklayenti, kuyise endaweni yamaseva aqanjiwe noma uyiyeke ithole wona ngendlela yephoyinti lokuxhumanisa isevisi; bese uqinisekisa imodi eyikhethile ngempela esikhundleni sokucabanga ukuthi inqubomgomo isetshenzisiwe:

Enable-BCHostedClient -ServerNames cache1.corp.example -UseSCP
Get-BCStatus | Select-Object BranchCacheIsEnabled, ClientMode

Yini esafinyelela kumthombo

Ukugcina ku-cache akususi imvume. Iklayenti elingenalo ilungelo lokufunda ifayela alitholi ukufinyelela ngenxa yokuthi omunye umuntu uligcinile ku-cache, futhi umthombo usaphendula umbuzo wemvume futhi unikeza ulwazi lokuqukethwe olwenza ukusesha kwe-cache kwenzeke. Uma umthombo ungafinyeleleki, ikhophi egcinwe ku-cache yodwa ayibi ukwabelana okungaxhunyiwe ku-inthanethi.

Izinguquko zokuqukethwe nazo zephula lowo mqondo buthule. Ifayela eligcinwa kabusha, elibhalwa kabusha noma elithintwa umkhiqizo wesipele lingase lingasahambisani ne-hashi egcinwe ku-cache, futhi ukufunda okulandelayo kubuyela kumthombo. Lokho kungukuziphatha okulungile, futhi yikho i-cache esethi yayo yokusebenza ishintsha njalo ngehora elinikeza okuncane.

Ukukhipha isithiyo sesithathu. I-cache inomkhawulo, ngakho isethi enkulu yokusebenza ikhiphela ngaphandle okuqukethwe okudala, futhi inzuzo incike ekutheni ukufunda kabusha kwenzeka ngaphambi kokukhipha hhayi ngemuva. Ukulinganisa i-cache yonke into eyabiwe kuyindlela ejwayelekile yokudumazeka ngokusetshenziswa okulungile ngokobuchwepheshe.

Yamukele ngokulandwa okubili nokulayisha okukodwa

Hlola imigudu emithathu elungile futhi ubhale ukuthi ngayinye ikhombisani. Ukulandwa kokuqala kwefayela elimelela kusuka kuklayenti, kukalwa kuxhumano lomthombo kanye nasewashi lomsebenzisi. Ukulandwa kwesibili kwefayela elifanayo elingashintshi kusuka kwelinye iklayenti eqenjini elifanayo lendawo. Ukulayisha okukodwa kwefayela elisha, okungafanele kukhombise intuthuko futhi kuqinisekisa ukuthi i-cache ayinikezwa udumo ngento engakaze iyenze.

Uma ukulandwa kwesibili kusawela uxhumano lomthombo engxenyeni enkulu yamabhayithi, i-cache ayisetshenziswa, futhi imbangela ngokuvamile iyiklayenti elisemodini engalungile, ukushicilelwa kwe-hashi okungekho kumthombo, noma i-cache esingathiwe ohlangothini olungalungile loxhumano oluvinjelwe. Lokho kuyizilungiso ezintathu ezihlukene, futhi kube okukodwa kuphela okumayelana nendawo yenethiwekhi.

Bese usho isiphetho ngendlela efanayo nesikhalo sokuqala: ukulandwa okuphindaphindiwe kokuqukethwe okungashintshi kusuka kulo mthombo kulezi zifundi kunikezwa yile cache. Konke okunye mayelana nokwabelana akuthintwanga, kuhlanganise ukulayisha, ukufakwa kuhlu kwamafolda kanye nendaba engaxhunyiwe ku-inthanethi, esadinga impendulo yayo.
