HCP dynamic host allocation protocol inoshandiswa zvakanyanya mukuwana zuva nezuva Internet, senge Internet yekumbarouteriri DHCP server. Patinoisa mutengi kuti atore otomatiki kero yeIP, sevha yeDHCP inopa IP kero kumutengi zvinoenderana neDHCP protocol.ONUinogona zvakare kushandiswa seDHCP maseva.
Iyo DHCP protocol inogovera otomatiki IP mapaketi emhando ina huru:
DHCP Ziva: Tumira nemutengi kuti uwane sevha yeDHCP.
DHCP Offer: Tumira neDHCP server, inoudza mutengi kuti ndinogona kupa IP kero.
DHCP Chikumbiro: Tumira nemutengi inoudza inoenderana neDHCP server kuti ndinoda IP kero.
DHCP ACK: Yakabudiswa neDHCP server kuti ipe IP kero yemhinduro yemutengi.
DHCP Kuburitswa: Kazhinji, mutengi anovharwa kana kuvharwa. Iyi meseji ichaita kuti sevha yeDHCP iburitse IP kero yemutengi anotumira meseji iyi.
DHCP Zivisa: Meseji inotumirwa nemutengi inokumbira rumwe ruzivo kubva kuseva.
DHCP Kuramba: Kana mutengi aona kuti IP kero yakapihwa nesevha haisi kuwanikwa (senge IP kero kusawirirana), meseji iyi inoburitswa ichizivisa sevha pamusoro pekushandiswa kweIP kero.
Panguva yekukurukurirana kweDHCP, UDP inoshandiswa seprotocol yekutumira. Iyo saiti inotumira chikumbiro kuDHCP server port 67 uye sevha inopindura meseji kune iyo host port 68.
1. Chikamu chekuwanikwa, apo mutengi weDHCP anotsvaga sevha yeDHCP (DHCPdiscover)
Mutengi weDHCP anotumira iyo DHCPdiscover ruzivo rwekutsvaga kuti iwane DHCP sevha mune yekutepfenyura modhi (nekuti IP kero yeDHCP server haizivikanwe kune mutengi), kureva, chaiyo nhepfenyuro ruzivo kukero 255.255.255.255. Wese anotambira panetwork neTCP/IP protocol anogashira iyi nhepfenyuro meseji, asi sevha yeDHCP chete ndiyo inopindura.
2.Provision phase, apo DHCP server inopa IP kero (DHCPoffer)
Imwe neimwe sevha yeDHCP munetwork inogamuchira kuwanikwa kweDHCPdiscover inopindura nekusarudza imwe yeIP kero isati yarendwa kumutengi weDHCP uye kutumira DHCPoffer inopa ine IP kero yakarejeswa uye mamwe maSettings kumutengi weDHCP.
3. Chikamu chekusarudza, umo mutengi weDHCP anosarudza IP kero inopiwa neDHCP server (DHCPrequest)
Kana paine zvinopfuura server imwe yeDHCP inopa ruzivo kuDHCPoffer inotumirwa nemutengi weDHCP, mutengi weDHCP anongogamuchira yekutanga DHCPoffer inopa ruzivo rwakatambirwa, uye yozopindura ruzivo rwechikumbiro cheDHCPrequest mune yekutepfenyura mode. Ruzivo urwu rune chikumbiro cheIP kero yeDHCP server yesarudzo yayo. Chikonzero chekupindura mukutepfenyura modhi ndeyekuzivisa ese maseva eDHCP kuti achasarudza IP kero yakapihwa neDHCP server.
4. Chikamu chekusimbisa, umo DHCP server inosimbisa iyo yakapihwa IP kero (DHCPack)
Kana sevha yeDHCP yagamuchira ruzivo rwechikumbiro cheDHCP chinopindurwa nemutengi weDHCP, inotumira meseji yekubvuma yeDHCP kumutengi weDHCP neIP kero yayakapa uye mamwe maSettings ekuudza mutengi weDHCP kuti inogona kushandisa IP kero yayakapa. Mutengi weDHCP anobva asunga TCP/IP protocol yake kunetiweki kadhi, uye ese maseva eDHCP, kunze kweyakasarudzwa nemutengi weDHCP, anotora kero yeIP yakapihwa.
5. Re-login (DHCPrequest)
Mune ramangwana, nguva imwe neimwe mutengi weDHCP paanopinda padandemutande zvakare, haidi kutumira zvakare DHCPdiscover ruzivo rwekutsvaga, asi inotumira zvakananga iyo DHCPrequest ruzivo rwekukumbira ine yakambopihwa IP kero. Kana sevha yeDHCP ikagamuchira ruzivo urwu, inoedza kurega mutengi weDHCP aenderere mberi nekushandisa kero yeIP yepakutanga nemhinduro nekubvuma kweDHCP. Kana IP kero isisagone kupihwa kune yepakutanga mutengi weDHCP (kana IP kero yakatopihwa kune mumwe mutengi weDHCP), server yeDHCP inopindura DHCPnack yekuramba meseji kumutengi weDHCP. Kana mutengi weDHCP wekutanga atambira meseji yekuramba iyi yeDHCPnack, inofanirwa kutumira meseji yekuwana DHCP kukumbira kero yeIP itsva.
6. Gadzirisa chibvumirano
Iyo IP kero yakabhadharwa neDHCP server kuDHCP mutengi kazhinji ine nguva yekurenda, mushure meiyo sevha yeDHCP inozotora kero yeIP yakakoswa. Kana mutengi weDHCP achida kuwedzera IP yayo yekurenda, inofanirwa kumutsidzira IP yayo yekurenda. Mutengi weDHCP anotumira otomatiki ruzivo kuseva yeDHCP kuti agadzirise IP yayo yekurenda zvese kana mutengi weDHCP atanga uye kana IP lease yapera.
