Ukucushwa kwe-SNMP
Kuphelileview
Uhlelo lwe-SNMP luhlanganisa izingxenye ezi-3 ezilandelayo:
- Iseva yokuphatha ye-SNMP (NMS)
- I-ejenti ye-SNMP (i-ejenti)
- I-MIB
I-SNMP iyiphrothokholi yesendlalelo sohlelo lokusebenza. Ihlinzeka ngefomethi yamaphakethe adluliswa phakathi kwe-NMS ne-ejenti.
Iseva yokuphatha ye-SNMP iyingxenye yohlelo lokuphatha inethiwekhi, njenge-CiscoWorks.
I-ejenti ye-SNMP ihlanganisa okuguquguqukayo kwe-MIB kanye neseva yokuphatha ye-SNMP ingaba
esetshenziselwa ukuphequlula noma ukushintsha amanani alezi ziguquko. Iseva yokuphatha ingathola ifayela le
amanani avela kumenzeli noma gcina lezi ziguquguqukayo kumenzeli. I-ejenti iqoqa idatha kusuka ku-MIB.MIB isizindalwazi samapharamitha wemishini kanye nedatha yenethiwekhi.
Isaziso se-SNMP
Uma kwenzeka umcimbi okhethekile, uhlelo luzothumela ulwazi kuseva yokuphatha ye-SNMP. Okwesiboneloampfuthi, lapho isistimu ye-ejenti ingena esimweni esingalungile, izothumela umlayezo kuseva yokuphatha.
Isaziso se-SNMP singathunyelwa njengogibe noma isicelo sokwazisa. Ngenxa yokuthi umamukeli uthola isicupho futhi akathumeli noma iyiphi impendulo, umthumeli ngeke akwazi ukuqinisekisa ukuthi isicupho samukelwe yini. Ngale ndlela, ugibe aluthembekile. Ngokuqhathaniswa, iseva yokuphatha ye-SNMP isebenzisa i-SNMP ukuphendula i-PDU, eyenziwa njengempendulo yalo mlayezo. Uma iseva yokuphatha ingasitholi isicelo sokwaziswa, ngeke ithumele impendulo. Uma isidlulisi singayitholi impendulo, sizodlulisela isicelo sokwaziswa futhi. Ngale ndlela, ulwazi lunethuba eliningi lokufika endaweni ehleliwe.

Ilungiselela Inani Lesikhathi Sokungenzi lutho
Umyalo usetshenziselwa ukulawula ukuvama kombuzo ngesikhathi sokungenzi lutho (ayikho idatha eshintshiwe)
Umyalo othi “cha” ungasetshenziselwa ukubuyisela inani elimisiwe.
Imodi yokumisa: Ukucushwa kwesixhumi esibonakalayo
Amanothi:
Ngesikhathi sokungenzi lutho, uhlaka lwe-I (ulwazi) luyashintshwa futhi uzimele we-RR (thola usulungile) uthunyelwa ekugcineni kwesilawuli kude ngezikhathi ezithile ukuze utshele isiphetho esikude ukuthi isiphetho sasendaweni silungele ukuthola idatha. Inani elincane elihlobene kufanele lisethwe ukuze kuqinisekiswe iseluleko esisheshayo ukuya ekugcineni okukude. Uma inani lisethwe lincane kakhulu, ozimele abaningi be-RR cishe bazothunyelwa kunethiwekhi.

Ilungiselela i-SDLC Njengendlela Embili Nemodi Ehambisanayo
Imodi yezindlela ezimbili ze-SDLC kanye nemodi efanayo ivumela isiteshi sokuxhumanisa se-SDLC esikhulu ukuthi sisebenzise isekethe ephelele ye-serial eyi-duplex. Lapho ukuvota okuvelele kwenzeka, isikhulu sesixhumanisi sesiteshi se-SDLC siyakwazi ukuthumela idatha esiteshini sezinceku. Imodi yezindlela ezimbili nangesikhathi esisodwa isebenza kuphela ohlangothini lwesiteshi esikhulu se-SDLC. Esiteshini sokuxhuma izigqila, iphendula okhethweni oluthunyelwe luvela esiteshini esikhulu.
I-SDLC yezindlela ezimbili kanye nemodi efanayo isebenza endaweni yokuxhumanisa enamagatsha amaningi noma indawo yokuxhumanisa iphoyinti nephoyinti.
Endaweni yokuxhumanisa amagatsha amaningi, isiteshi esikhulu sezindlela ezimbili kanye nesikhathi esifanayo siyakwazi ukuvotela isiteshi sezigqila futhi sithole idatha evela esiteshini sezigqila futhi sithumele idatha (uhlaka lolwazi) kwezinye iziteshi zezigqila.
Endaweni yokuxhumanisa iphuzu-kuya-iphuzu, inqobo nje uma kungekho mkhawulo omkhulu wokufinyelela efasiteleni, isiteshi esikhulu sezindlela ezimbili kanye nesikhathi esifanayo siyakwazi ukuthumela idatha (uhlaka lolwazi) esiteshini sezigqila ngisho noma kunokuvota okuvelele. .
Noma yimuphi wemiyalo ungasetshenziswa ngaphansi kwemodi yokucushwa kwesixhumi esibonakalayo ukuze kusebenze izindlela ezimbili kanye nemodi efanayo:

Ilungiselela Isikhathi Se-SDLC Nezikhathi Zokuthumela Kabusha
Lapho indawo yokusebenza ye-SDLC ithumela uhlaka, izolinda impendulo yokuphela kokwamukela. Impendulo ikhombisa ukuthi uhlaka lwamukelwe. Isikhathi sokuphendula esivunyelwe umzila ngaphambi kokuthumela kabusha uhlaka singashintshwa. Izikhathi zokuthumela kabusha uhlaka ngesofthiwe zingasethwa ngaphambi kokunqamula inqubo yeseshini ye-SDLC. Ngokulawula lawa manani, ngokulawula lawa manani, i-overhead yenethiwekhi ingancishiswa ngokuqhubeka nokuthola uhlaka oludlulisiwe.
Umyalo owodwa noma emibili ngezansi ingasetshenziswa ngaphansi kwemodi yokucushwa kwesixhumi esibonakalayo ukuze ulungiselele isibali sikhathi se-SDLC nezikhathi zokudlulisela kabusha:

Ubude obukhulu bozimele wokufaka kanye nenani eliphezulu lohlaka lolwazi (noma usayizi wewindi) elitholwe ngaphambi kokuba umzila uthumele impendulo ekugcineni kungalungiselelwa. Uma inani elimisiwe likhulu ngokuqhathaniswa, i-overhead yenethiwekhi ingancishiswa. Umyalo ongezansi ungasetshenziswa ngaphansi kwemodi yokumisa isixhumi esibonakalayo ukuze ulungise ifreyimu ye-SDLC kanye nenombolo yohlaka lolwazi.
Ukulawula Usayizi Wenqolobane
Usayizi wenqolobane ungalawulwa. Inqolobane isetshenziselwa ukugcina idatha enganqunywanga ukuthi ithunyelwe esiteshini esikude se-SDLC. Umyalo uwusizo ikakhulukazi kumishini yokuguqula iphrothokholi ye-SDLC esebenzisa ukuxhumana phakathi kwesiteshi sokusebenzela se-SNA esinephrothokholi yesingqimba sesixhumanisi siyi-LLC2 kunethiwekhi yendawo yethokheni (LAN) kanye nendawo yokusebenza ye-SNA ephrothokholi yongqimba yesixhumanisi iyi-SDLC kusixhumanisi sochungechunge.

Ukulawula ukuvota kwesiteshi sezigqila
Isikhathi sokuvota kwerutha esiteshini sezigqila, ubude besikhathi sokuthumela idatha
kusukela esiteshini esikhulu kuya esiteshini sezigqila nokuthi isofthiwe ikhetha isikhathi esingakanani isiteshi sezigqila ngaphambi kokuthuthela esiteshini esilandelayo singalawulwa.
Amaphuzu alandelayo kufanele aqashelwe ekusebenziseni le miyalo:
Kuphela uma isiteshi sezigqila siphenywa yisiteshi esikhulu, imininingwane ingadluliselwa. Lapho ukuvota kuphela futhi nenani lesibali sikhathi likhulu kakhulu, isikhathi sokuphendula sesiteshi sezigqila sizokwengeza. Uma inani lesibali sikhathi lehliswa lincane kakhulu, lizoholela ekuminyanisweni kwesixhumanisi se-serial kanye nezikhukhula zedatha ngenxa yezinhlaka zokuvota eziningi kakhulu nezingenasidingo ezithunyelwe kusukela esiteshini sezigqila, okuthatha isikhathi esengeziwe se-CPU ukubhekana nazo.
Ukusebenza kahle kokuxhumana phakathi kwesiteshi esikhulu nesiteshi sezigqila esisodwa kungathuthukiswa ngokwandisa inani elilinganiselwe lokuvota, kodwa kungase kubambezele ukuvota kwezinye iziteshi zezigqila.
Umyalo owodwa noma eminingi ngezansi ingasetshenziswa ngaphansi kwemodi yokumisa isixhumi esibonakalayo sokulawula ukuvota kwesiteshi sezigqila: Ifomethi ethi “def” yale miyalo ingasetshenziselwa ukubuyisela kunani lokuvota elizenzakalelayo.

Ngokuvamile, irutha kanye nemishini ye-SDLC esebenzisana nephrothokholi yomzila izosekela ubude obufanayo nobukhulu bohlaka lolwazi lwe-SDLC. Uma inani lilikhulu, yilapho isixhumanisi sisetshenziswa kahle futhi nokusebenza kuzoba ngcono.
Ngemuva kokuthi okokusebenza kwe-SDLC kucushwe nohlaka lolwazi oluphezulu olungase luthunyelwe, umzila uzolungiselelwa ukusekela ubude obufanayo obukhulu bohlaka lolwazi. Inani elizenzakalelayo lingamabhayithi angu-265. Inani eliphakeme elisekelwa isofthiwe kufanele libe lincane kunevelu yozimele ephezulu ye-LLC2 echazwe ngesikhathi sokumisa ubude bomkhawulo wolwazi lwe-LLC2.
Umyalo ongezansi ungasetshenziswa ngaphansi kwemodi yokumisa isixhumi esibonakalayo ukuze ulungise inani eliphezulu lohlaka lolwazi lwe-SDLC:

Ukuqapha Indawo Yokusebenzela ye-SDLC
Umyalo ongezansi ungasetshenziswa ngaphansi kwemodi yokuphatha ukuqapha ukumiswa kwendawo yokusebenza ye-SDLC nokunquma ukuthi iyiphi ipharamitha ye-SDLC okufanele ilungiswe.
