• "Kugwirizanitsa koloko m'machitidwe ogawidwa?"

Kulunzanitsa koloko pamakina ogawidwa ndi nkhani yofunika kwambiri kuti muwonetsetse kuti magwiridwe antchito ndi kulumikizana pakati pa zigawo ndi mfundo. pa netiweki. Pansipa pali kalozera sitepe ndi sitepe Kuti mumvetsetse ndikukwaniritsa kulumikizana kwa wotchi pamakina ogawidwa:

1. Mvetserani kufunikira kwa kulunzanitsa koloko: Mu dongosolo logawidwa, ndikofunikira kuti node zonse zikhale ndi lingaliro lofanana la nthawi. Izi zimapangitsa kuti zochitika zizichitika mwadongosolo komanso kulumikizana pakati pa node kukhala kothandiza.

2. Dziwani zovuta: Kulunzanitsa koloko m'makina ogawidwa kumakumana ndi zovuta chifukwa cha zinthu zosiyanasiyana zomwe zingakhudze nthawi, monga kuchedwa kwa maukonde, kupotoza, ndi zolakwika za wotchi. Kumvetsetsa zovutazi ndikofunikira pakukhazikitsa njira zoyenera zolumikizirana.

3. Fufuzani njira zamalumikizidwe: Pali ma aligorivimu angapo ndi ma protocol opangidwa kuti akwaniritse kulumikizana kwa wotchi pamakina ogawidwa. Zitsanzo zina Zodziwika bwino ndi algorithm ya Cristian, algorithm ya Berkeley, ndi Network Time Protocol (NTP). Ndikofunika kufufuza ndikumvetsetsa momwe njirazi zimagwirira ntchito musanasankhe yoyenera kwambiri pa dongosolo lanu.

4. Konzani njira yolumikizira yosankhidwa: Mukasankha algorithm yolumikizirana kapena protocol, muyenera kuyikonza bwino pamakina anu ogawidwa. Izi zimaphatikizapo kusintha magawo ofunikira ndikuwonetsetsa kulumikizidwa koyenera ndi ma node omwe alipo.

5. Yang'anirani ndikusintha: Pambuyo pokhazikitsa kulumikizana kwa wotchi, ndikofunikira kuyang'anira mosalekeza momwe mawotchi amagwiritsidwira ntchito komanso kulondola kwa mawotchi. Ngati zazindikirika zopatuka, zokonda zingafunikire kusintha kapena kuwunika kolondola kwambiri.

6. Sungani dongosolo losinthidwa: Pamene machitidwe omwe amagawidwa akusintha, ndikofunikira kuti mukhale osinthika ndi kupita patsogolo kwatsopano mu ma aligorivimu a mawotchi ndi njira. Kukhala pamwamba pa kafukufuku waposachedwa ndi zosintha zimatsimikizira kuti makina anu nthawi zonse akuyenda molondola komanso moyenera.

Kulunzanitsa koloko m'machitidwe ogawidwa Ndi njira zovuta koma zofunikira kuti zitsimikizire kulumikizana koyenera ndikugwira ntchito mumanetiweki ogawidwa. Potsatira izi, mudzatha kumvetsetsa ndi kukwaniritsa kugwirizanitsa kolondola, zomwe zidzasintha kwambiri machitidwe anu ogawidwa.

Mafunso ndi mayankho okhudza kulunzanitsa koloko m'makina ogawidwa

Kodi kulunzanitsa koloko m'makina ogawidwa ndi chiyani?

Kulunzanitsa koloko m'machitidwe ogawidwa ndi njira yolumikizira mawotchi a zipangizo zosiyanasiyana kapena node mu netiweki kuti akhazikike ku nthawi yofanana. Izi ndizofunikira makamaka m'malo omwe kuwongolera kwakanthawi kwakanthawi pakati pazochitika kumafunikira kapena kuwonetsetsa kupezeka ndi kulondola pamapulogalamu omwe amagawidwa.

Chifukwa chiyani kulunzanitsa koloko ndikofunikira pamakina ogawidwa?

Kuyanjanitsa koloko pamakina ogawidwa ndikofunikira chifukwa:

1. Imakulolani kuti mukhazikitse dongosolo lakanthawi pakati pa zochitika pamapulogalamu ogawidwa.
2. Pewani kusagwirizana ndi zolakwika zomwe zimachitika chifukwa cha kusagwirizana kwa nthawi pakati pa ma netiweki.
3. Imathandizira kukonza ndi kugwirizanitsa ntchito mu machitidwe ogawidwa.
4. Imathandiza kusanthula kwanthawi ndi kukonza zolakwika.

Kodi kulunzanitsa koloko kumatheka bwanji m'makina ogawidwa?

Kulunzanitsa koloko m'machitidwe ogawidwa Zingatheke kudzera mu:

1. Njira zolumikizirana monga NTP (Network Time Protocol) kapena PTP (Precision Time Protocol)

Kodi Network Time Protocol (NTP) ndi chiyani?

NTP (Network Time Protocol) ndi njira yolumikizira mawotchi yomwe imagwiritsidwa ntchito kwambiri pamanetiweki apakompyuta. Imalola zida kupeza ndikusintha nthawi yawo motengera ku seva nthawi yeniyeni.

Kodi Precision Time Protocol (PTP) ndi chiyani?

PTP (Precision Time Protocol) ndi njira yolumikizira mawotchi yomwe imapereka kulondola kwambiri komanso kulondola pakugwirizanitsa machitidwe ogawidwa. Amagwiritsidwa ntchito nthawi zambiri m'mapulogalamu omwe amafunikira kulondola nthawi yayitali kwambiri, monga ma netiweki amafoni kapena makina owongolera mafakitale.

Ubwino wogwiritsa ntchito wotchi ya atomiki pamalumikizidwe ogawidwa ndi otani?

Ubwino wogwiritsa ntchito wotchi ya atomiki polumikizana ndi makina ogawa ndi awa:

1. Kulondola kwambiri komanso kukhazikika kwa nthawi komwe kumaperekedwa ndi mawotchi a atomiki.
2. Kukana zosokoneza zakunja zomwe zingakhudze kulondola kwa ulonda wamba.
3. Kutha kusunga nthawi yolondola ngakhale zitatayika kulumikizidwa ndi mfundo zina.

Kodi ma aligorivimu amawunikira omwe amagawidwa kwambiri ndi ati?

Ma algorithms odziwika kwambiri a synchronization ndi awa:

1. Berkeley algorithm.
2. Algorithm ya Cristian.
3. Lamport algorithm.
4. Marzullo algorithm.

Kodi algorithm ya Berkeley ndi chiyani?

Berkeley algorithm ndi njira yogawa yolumikizira yomwe imalola ma node mudongosolo kuti asinthe nthawi yawo molingana ndi wotchi yayikulu. Zili ndi masitepe awa:

1. Node ya master imatumiza nthawi yake ku node pa intaneti.
2. Ma node amasintha nthawi yawo potengera kusiyana pakati pa nthawi yawo yamakono ndi nthawi yomwe amalandira kuchokera ku master node.
3. Kusiyanasiyana kwa nthawi mu netiweki kumachepetsedwa kuti apititse patsogolo kuyanjanitsa.

Kodi algorithm ya Cristian ndi chiyani?

Cristian's algorithm ndi njira yogawa yolumikizira yomwe imalola node kufunsa nthawi yomwe ilipo kuchokera pa seva yanthawi. Zili ndi masitepe awa:

1. Node ya kasitomala imatumiza pempho la nthawi kwa seva.
2. Seva imayankha ndi nthawi yake.
3. Node ya kasitomala imawerengera kusiyana kwa nthawi pakati pa nthawi yolandiridwa ndi nthawi yake yapitayi, motero kusintha kugwirizanitsa kwake.
