IGMP snooping: ariā me te whakamahi o

Hei uru i roto i te rōpū o ngā pūrere whatunga me pouara IP-kōpuku whakamahi i te kawa IGMP. whakahaere Kawa Whakahaere Rōpū Ipurangi multicast (rōpū) raraunga tuku whatunga. Kei i te taumata whatunga me hono te rorohiko kiritaki ki te pouara rohe ki te tuku i te raraunga i waenganui ia ratou. Na ka whakahaua waka multicast ki ētahi atu kiritaki i roto i kawa PIM. hono te reira i te pouara rohe ki te mamao. Na roto i te whakamahi o ngā rauemi whatunga IGMP o te maha o ngā tono (kēmu ipurangi, tarere ataata) Ka taea te whakamahi ake tōtika.

A faaoti i runga i haapurororaa waka i roto i etahi atanga tukua te whakamahi o IGMP snooping mahi. He aha te mea te reira? Tenei tukanga tono IGMP-aroturuki i kiritaki (mano) ki kaituku (pouara multicast).

Ko te ariā me te whakaaro o IGMP snooping

I roto i te reo Ingarihi tikanga te snooping "hūhunu". A, no te whakahohe, te pūrere whatunga takawaenga (pouara pūrere ranei) tīmata ki te tātari i te tuku o pākete raraunga katoa kawea i waenganui i rorohiko kiritaki hono taua, me pouara, tuku waka multicast. A, no te kimi i te tono mo te hononga kē te tauranga hono ki te kaiwhakamahi (kiritaki), i roto i te āhuatanga ritenga (Waiho Tono) mukua te hāngai tauranga i te rōpū.

He wātea te nuinga mahi kōrero IGMP snooping, engari titau mua whakahohenga-.

He aha te aroturuki i te waka whatunga?

taea te tuku Romamaha-waka, tae atu rorohiko, e kore e hiahia i roto i reira. huaina ana tēnei ko te retransmission pāhotanga. Hei ārai i te reira, ki te whakaiti i te kawenga i runga i te whatunga te whakamahi i IGMP snooping. I te wa ano, e rapu tenei momo o te tātari kohi mahara atu, me te faarahi te kawenga i runga i te pūrere. Heoi, ko reira tika.

Ki te tīmata te pūrere ki te tuku waka multicast ki ona tauranga katoa, ka:

• He horihori tenei tukanga;
• kia ara ake raruraru i roto i te mahi o te kaiwhiwhi whakamutunga (pūrere whatunga), takoha ki te hapai i te rere nui o ngā raraunga faufaa.

Hei karo taua āhuatanga, i reira he IGMP snooping āhuatanga e nui whakapiki i te mahi o te whatunga katoa. whakatutuki te reira i te mau hinaaro o te taumata whatunga (te toru), me te kupu aa hongere (tuarua) taumata o te whakawhiti raraunga.

Ko te whakaurunga o te mahi wiretapping

I roto i te tikanga ki te aroturuki o multicast-waka, me te tuatahi taea ai e koe IGMP snooping me whakaturia ai koe ki runga. Fakakaukau ki he founga ki te mahi i tenei i runga i kōrero D-Link ka whakatinana kaupapa tuku raraunga multicast. Teams ki te whakarei ake wiretapping whatunga:

I roto i te tikanga ki te aukati i te tauranga i te rōpū whatunga ina kua riro te pūrere tono Waiho i te kiritaki, te whakamahi i IGMP snooping Waiho Nohopuku mahi. āhei te reira ki a koe te aukati i te tuku o rerenga raraunga tikanga puta noa i te whatunga ki te tirohanga ki te mahi pai ake. Hei whakahohe i tēnei āhuatanga, te whakamahi i te whakahau e whai ake nei:

Kei te whakamahia te reira i roto i te kaupapa e hiahia ana koe ki te taea tātari pana tohatoha multicast ki te kōpuku hono whai wāhi i roto i te tuku raraunga.

Momo IGMP-wiretapping

Ka taea e IGMP snooping mahi kia rua hāngū me te kaha. I roto i te aha ara?

1. e kore e hāngū te tātari waka, engari e pupuri noa ara o reira.
2. Active - whakarongo me pākete tātari raraunga ki te whakaiti i te mahi o te rōpū pouara.

Ko te momo tuarua o te whakatinanatanga o tenei mahi ko te tino meinga, mai taea reira ki te whakaiti i te nui o ngā mōhiohio tuku e tono hononga filtration ki te pouara me atu i reira.

Taumahinga IGMP āwhina snooping-whitiwhiti whakaiti i te kawenga i runga i te whatunga mā te aroturuki tukanga reira utu raraunga i waenga i nga kaiwhakarato (pouara rohe) me ngā kaiwhakamahi (rorohiko kiritaki) waka multicast.
