Tsarin Gudanar da Hanya a cikin Cibiyoyin Sadarwa
Tsarin hanya muhimmin bangare ne na tsara da aiki da hanyar sadarwa ta kwamfuta. Tsarin hanya yana nufin tsarin tantance hanya mafi kyau ko hanya daga wuri zuwa wuri a cikin hanyar sadarwa. Tsarin hanya shine tsarin da na'urorin sadarwa ke amfani da shi don tantance hanya mafi kyau a cikin hanyar sadarwa. Wannan labarin zai bincika nau'ikan tsarin hanya daban-daban waɗanda ke taka muhimmiyar rawa a cikin ayyukan hanyar sadarwa, gami da vector na nesa, yanayin haɗi, da algorithms masu haɗaka.
Pendahuluan
A cikin hanyar sadarwa, bayanai dole ne su ratsa ta wurare da dama na tsakiya don isa ga inda za su je. Kowanne daga cikin waɗannan wuraren ana kiransa da node, kuma tsarin aika bayanai tsakanin waɗannan nodes yana buƙatar algorithm na routing. Ta amfani da algorithm na routing, na'urar sadarwa za ta iya tantance hanya mafi inganci da sauri don aika fakitin bayanai.
Algorithms na hanya suna aiki bisa ga ma'auni da dama kamar nisan, farashi, bandwidth, jinkiri, kaya, da ƙari. Zaɓar tsarin hanya mai dacewa yana da mahimmanci don kiyaye ingancin hanyar sadarwa da aminci.
Rukunin Tsarin Lantarki na Hanyar Hanya
Ana iya rarraba algorithms na hanya zuwa nau'ikan da dama bisa ga wasu sharuɗɗa, kamar hanyar sabunta bayanai, nau'in hanyar sadarwa da aka tallafa, da sigogin ingantawa.
1. Tsarin Vektor na Nisa
Tsarin Distance Vector yana ɗaya daga cikin hanyoyin farko kuma mafi sauƙi don amfani da hanyar sadarwa. Misalin da aka fi sani da wannan tsarin sadarwa shine Tsarin Bayani na Hanyar Sadarwa (RIP).
Ka'idoji na Asali
Wannan tsarin yana aiki ta hanyar sanya kowace na'ura mai ba da hanya tsakanin hanyoyin sadarwa ta kula da teburin hanya wanda ke ɗauke da jerin hanyoyin da za a iya bi da kuma nuna nisan da za a bi zuwa takamaiman wurare. Ana sabunta waɗannan tebura lokaci-lokaci ta hanyar aika bayanai game da hanya zuwa maƙwabtan na'ura mai ba da hanya tsakanin hanyoyin sadarwa. Tsarin sabuntawa ya ƙunshi manyan matakai uku:
– Farawa: Kowane na'urar sadarwa ta san cewa nisan da ke tsakaninta da kanta sifili ne kuma nisan da ke tsakaninta da kowace na'urar sadarwa da aka haɗa kai tsaye shine farashin wannan hanyar haɗin.
– Musayar Hanya: Kowace na'urar sadarwa tana aika teburin hanyarta lokaci-lokaci zuwa na'urorin sadarwa na maƙwabta.
– Sabunta Tebur: Kowace na'ura mai ba da hanya tsakanin hanyoyin sadarwa tana karɓar bayanai daga maƙwabtanta kuma, idan ta sami gajeriyar hanya zuwa inda za ta je, tana sabunta teburin hanyar sadarwarta.
Abũbuwan amfãni da rashin amfani
Babban fa'idar tsarin Distance Vector shine sauƙinsa. Duk da haka, yana da matsaloli da dama, kamar matsalolin haɗuwa a hankali da kuma yiwuwar madaukai na hanya, inda bayanai ke ci gaba da zagayawa ta hanyar hanyar sadarwa ba tare da isa inda aka nufa ba.
2. Tsarin Haɗin Jiha
Domin magance raunin Distance Vector, an ƙirƙiro algorithms na Link State. Misalin aiwatar da wannan algorithm shine Open Shortest Path First (OSPF).
Ka'idoji na Asali
A cikin wannan tsari, kowace na'ura mai ba da hanya tsakanin hanyoyin sadarwa tana da cikakken hoto na yanayin hanyar sadarwa kuma tana ƙididdige mafi kyawun hanya bisa ga wannan bayanin. Matakan gabaɗaya a cikin tsarin Link State sun haɗa da:
– Farawa: Kowace na'ura mai ba da hanya tsakanin hanyoyin sadarwa tana ba da yanayin haɗi tare da duk maƙwabtanta na kusa, gami da farashin hanyar haɗin.
– Musayar Bayanai: Na'urorin sadarwa suna watsa bayanai ta hanyar haɗa bayanai zuwa duk sauran na'urorin sadarwa a cikin hanyar sadarwa ta hanyar fakitin Link State Advertises (LSA).
- Tsarin Taswirar Cibiyar Sadarwa: Tare da LSAs da aka karɓa, kowace na'ura mai ba da hanya tsakanin hanyoyin sadarwa tana gina cikakken taswirar hanyar sadarwa.
– Lissafin Hanya: Da zarar an samar da cikakken taswirar hanyar sadarwa, ana amfani da tsarin Dijkstra ko wani tsari makamancin haka don ƙididdige hanya mafi guntu zuwa inda za a je.
Abũbuwan amfãni da rashin amfani
Algorithms na yanayin haɗin gwiwa suna da sauri a haɗuwa kuma sun fi tsayayya da madaukai na hanya. Duk da haka, sun fi rikitarwa kuma suna buƙatar ƙarin albarkatu, gami da ƙwaƙwalwa da lissafi.
3. Tsarin Aiki Mai Haɗaka
Algorithms na hanyoyin sadarwa na haɗakarwa sun haɗa mafi kyawun abubuwan Distance Vector da Link State. Misali ɗaya na tsarin haɗin gwiwa shine Enhanced Interior Gateway Routing Protocol (EIGRP).
Ka'idoji na Asali
Misali, EIGRP yana amfani da matakin Distance Vector don rarraba bayanai game da hanya amma kuma ya haɗa da wasu fasalulluka na Link State, kamar sabunta yanayin ƙasa da sake ƙididdigewa. Wannan yana bawa EIGRP damar:
- Yana samar da haɗuwa cikin sauri fiye da tsararren ka'idojin Vector na Distance.
– Yana guje wa yawan nauyin da ake samu a cikin ka'idojin Link State.
Abũbuwan amfãni da rashin amfani
Algorithms na haɗin gwiwa suna ba da daidaito tsakanin saurin haɗuwa da ingancin albarkatu. Duk da haka, aiwatar da su ya fi rikitarwa fiye da tsarin Distance Vector mai sauƙi.
Sigogi na Ma'auni a Tsarin Hanya
Zaɓin hanyar da ta fi dacewa ya dogara da ma'auni da dama waɗanda algorithm na hanya zai iya amfani da su:
– Nisa: Yawanci ana ƙididdige shi a cikin "ƙidayar tsalle" ko tsalle tsakanin ƙusoshi.
– Bandwidth: Yana samar da hanyoyi masu girman da za a iya amfani da su.
– Jinkiri: Zaɓi hanya bisa ga mafi ƙarancin lokacin tafiya.
– Aminci: Ba da fifiko ga hanyoyin da suka fi kwanciyar hankali da aminci.
– Lodawa: Yana rarraba zirga-zirga daidai gwargwado don guje wa wuce gona da iri.
Yawancin ka'idojin hanya na zamani suna ba da damar amfani da haɗin ma'auni da yawa don tantance hanya mafi kyau.
Kammalawa
Algorithms na hanya suna taka muhimmiyar rawa a cikin inganci da amincin hanyoyin sadarwa na kwamfuta. Ba wai kawai suna tantance hanya mafi kyau don isar da bayanai ba, har ma suna daidaitawa da canjin yanayin hanyar sadarwa. Mafi kyawun zaɓi na hanyar sadarwa ta hanya ya dogara da takamaiman buƙatun hanyar sadarwa da ake magana a kai, gami da girma, wadatar albarkatu, ko wasu sharuɗɗa.
A cikin duniyar da ke cike da buƙatun sadarwa na bayanai da ke ci gaba da bunƙasa, fahimtar cikakken tsarin hanyoyin sadarwa da aikace-aikacensu babban jari ne ga ƙwararrun hanyoyin sadarwa. Tare da nau'ikan tsarin sadarwa iri-iri, gami da Distance Vector, Link State, da kuma tsarin haɗin gwiwa, akwai mafita da aka tsara don kusan kowace ƙalubalen hanyar sadarwa.
