IGMP snooping: lingaliro ndi ntchito ya

Kulowa IP-mfundo gulu la zipangizo zopezera ndi routers ntchito protocol IGMP. Internet Gulu Protocol Management amalowerera multicast (gulu) deta kufala Intaneti. Malowa ali pamtunda pa mlingo maukonde ndi kasitomala kompyuta zikugwirizana kwa rauta m'dera popereka deta pakati pawo. Ndiye magalimoto multicast anawalozera kwa makasitomala ena mwa protocol pimu. Izo zikugwirizana ndi rauta m'dera kutali ndi. Pogwiritsa ntchito IGMP chuma zopezera angapo ofunsira (masewera online, akukhamukira kanema) zikhoza kugwiritsidwa ntchito bwino.

Sankhani Kuwulutsa malonda ena polumikizira kulola ntchito IGMP snooping ntchito. Ndi chiyani icho? Izi ndondomeko zopempha IGMP-kutsatira kwa ogula (makamu) kwa ogulitsa (multicast routers).

Lingaliro ndi cholinga IGMP snooping

Mu English ndi snooping amatanthauza "mobisa zimene ankaphunzira". Pamene adamulowetsa, ndi wapakatikati maukonde chipangizo (rauta kapena chipangizo) wayamba yosanthula kufala kwa mapaketi onse deta ikuchitika pakati pa kompyuta kasitomala chikugwirizana thereto ndi routers m'dipatimenti magalimoto multicast. Pamene kupeza pempho kwa kugwirizana ndi anazimitsa doko olumikizidwa kwa wosuta (kasitomala), zinthu zosiyana (Siyani Funsani) doko lolingana ndi zichotsedwa ku gulu.

Ambiri kulankhulana IGMP snooping ntchito akupezeka, koma pamafunika chisanadze kutsegula.

Chifukwa chiyani tikuyenera kuunikira ndi magalimoto maukonde?

Multicast-magalimoto akhoza opatsirana kuphatikizapo makompyuta, osati chidwi. Zimenezi zimatchedwa kuulutsa retransmission. Pofuna kupewa izi, kuchepetsa katundu maukonde ntchito IGMP snooping. Pa nthawi yomweyo, mtundu wa zosefera amafuna zina mowa kukumbukira ndi kumawonjezera katundu pa chipangizo. Komabe, n'chofunikira.

Ngati chipangizo wayamba kupereka magalimoto multicast kuti madoko ake onse, ndiye:

• ndondomeko izi chilibe ntchito
• mavuto amene mungakumane ntchito ya wolandira chomaliza (maukonde chipangizo), anakakamizika nkhani otaya lalikulu deta zosafunika.

Kupewa zinthu zoterezi, IGMP snooping Mbali kwakukulu bwino ntchito maukonde lonse. Iwo akulankhula zosowa za Intaneti (chachitatu) mlingo ndipo potero optimizes njira (wachiwiri) mlingo wa kutengerapo deta.

Kulolerana wa ntchito wiretapping

Pofuna kukhala ndi njira yolongosoka multicast-magalimoto, muyenera choyamba athe IGMP snooping ndi kuuika nokha. Taganizirani mmene tingachitire zimenezi pa kulankhulana D-Link pamene ndikukhazikitsa multicast deta kufala chiwembu. Magulu kumapangitsanso maukonde wiretapping:

Pofuna kuti achotse doko ku gulu maukonde pamene chipangizo walandira pempho Acoka ku kasitomala, ntchito IGMP Snooping Fast Atuluka ntchito. Timatha inu kuletsa kufala kwa utuluke deta zosafunika kudutsa maukonde nyaze opaleshoni zosavuta. Kuti athe mbali iyi, ntchito lamulo lotsatirali:

Izo ntchito kukachitika kuti muyenera kuti athe imathandiza multicast yogawa lophimba ndi mfundo zikugwirizana nawo kufala deta.

Mitundu IGMP-wiretapping

IGMP snooping ntchito zimakhala chabe ndi akuchitachita. M'njira yotani?

1. Chabe sikuti zosefera magalimoto, koma amasunga akudziŵa izo.
2. Yogwira - amamvetsera ndi sefa deta mapaketi kuchepetsa wakewo wa gulu rauta.

Mtundu wachiwiri wa kukhazikitsa nchito imeneyi ndi ambiri ankakonda chifukwa zimathandiza kuchepetsa kuchuluka kwa mfundo kudzera mwa zopempha kusefera kugwirizana kwa rauta ndi kulichotsa ilo.

Magwiridwe IGMP snooping-wolankhula amathandiza kuchepetsa katundu maukonde ndi kutsatira izo njira deta kuwombola pakati wosamalira (routers wamba) ndi ogwiritsa (kasitomala kompyuta) multicast magalimoto.
