Mutambo wekutarisa ndiwo data link layer, digital packet switching network protocol teknolojia yakagadzirirwa kubatanidza Local Area Networks (LANs) uye kuendesa dharaunda kuWide Area Networks (WANs) . Frame Relay inoshandisa imwe yemichina inoshandiswa seyo X.25 uye yakawana mukurumbira muUnited States sechinhu chinonyanyogadzirisa sangano re Integrated Services Digital Network (ISDN) rinotengeswa kune vatengi vemabhizimisi.
Mafambiro akaita Relay Framework Anoshanda Sei
Murairo Relay unobatanidza multiplexing yemotokari kubva kune dzimwe hukama huri pamusoro pekubatanidza kwekubatana kwechinhu uchishandisa zvikamu zvakasiyana-siyana zvinonzi hardware zvinosanganisira ruvara rwemafirimu, mabhiriji, uye shanduko dzinopinza data mune rimwe rega Relay Relay messages. Kushandiswa kwega kwega kunoshandisa gumi (10) bit Data Link Connection Identifier (DLCI) yekutengesa kero yakasiyana. Mhando mbiri dzekubatana dziripo:
- Permanent Virtual Circuits (PVC) - nekuda kwekubatanidza kusungirirwa kunofanirwa kuchengetwa kwenguva yakareba kunyange kana pasina deta iri kuendeswa mberi
- Akashandura Virtual Circuits (SVC) - kwekugadzirisa kwenguva pfupi kunongogara kwenguva imwe chete
Mutambo Relay unobudirira unobudirira nani kupfuura X.25 pamutengo wakaderera zvikuru hausi kuita chero kukanganisa kururamisa (izvo zvinoshandiswa pane zvimwe zvikamu zve network), kuderedza zvikuru network latency . Inobatsirawo kutengesa-urefu hwepakati yepaketani hukuru kuitira kushandiswa kwakanyanya kwehutano hwomukati .
Mutambo Relay unoshanda pane fiber optic kana ini I- SDN mitsara uye inogona kutsigira zvakasiyana-siyana mitemo yenhungetedzo yenyika kusanganisira Internet Protocol (IP) .
Basa reChechi Relay
Murairo Relay unotsigira dhigirii yemadhora eT1 neT3 mitsara - 1.544 Mbps uye 45 Mbps, pamwe chete, nehutano hwehutano kusvika 56 Kbps. Inotsigirawo fiber connections kusvika ku 2.4 Gbps.
Chikwata chimwe nechimwe chinogona kugadzirirwa neCommission Information Rate (CIR) iyo protocol inochengetedza zvisiri izvo. CIR inoreva kuderera kwehuwandu hwekutsvaga hutano hunofanira kutarisira kugamuchira pasi pemamiriro ezvinhu akachengetedza (uye inogona kudarika apo chibvumirano chemuviri chakakosha chine simba rakakwana rekutsigira tit). Murairo Relay haugadziri kushanda kwepamusoro kune iyo yeCIR asiwo inobvumira kufamba kwepamusoro, uko kuwirirana kunogona kwechinguva (kazhinji kwemasviki maviri) kupfuura CIR yayo.
Nyaya neChechi Relay
Frame Frame Relay yakaratidza nzira inobhadhara yekambani dzekutengesa kutumira data pamusoro pamakungwa marefu. Iyi teknolojia yakaderera pakuzivikanwa sezvo makambani ari kuchinja zvishoma nezvishoma kudhonza kwavo kune dzimwe Internet Protocol (IP) based solutions.
Makore apfuura, vazhinji vakaona Asynchronous Transfer Mode (ATM) uye Frame Relay semakwikwi chaiwo. ATM inoshandiswa zvakasiyana neChechi Relay, zvisinei - kushandiswa kwenguva yakatarwa pane kutsvaga urefu hwepakati uye inoda mari inodhura yakawanda kushanda.
Frame Relay yakazopedzisira yakatarisana nemakwikwi ane simba kubva kuMaplS - Multi-Protocol Label Switching. Nzira dzeMPLS dzave dzakashandiswa zvakanyanya paIndaneti routers kuti ibudirire kugonesa Virtual Private Network (VPN) mhinduro dzaiwanzodikanwa Frame Relay kana zvimwe zvinogadziriswa.
