Ndezvipi zvinobatsira zvemasangano ekukurukurirana evanhu vakawanda?

Rimwe zita rekukurukurirana kwe multiservice ndi NGN, iyo, muchiChirungu, inonzwika New Generation Networks kana Next Generation Network. Multiservice nhaurirano mitambo inoshandiswa nhengo dzechizvarwa chitsva. Mhemberero ndeye IP mitambo inotsigira runyararo ruzere kana rwakakwana rwemashoko akawanda anodiwa, multimedia uye data. Multiservice nhaurirano inoshanda inoshandiswa pamutemo wekushandura kwemasangano ekuterevhizheni.

Ndezvipi zvaidiwa kutanga kweNNN?

Pakupedzisira, ruzivo rwakasiyana-siyana rwakaparadzirwa kuburikidza nematare ehurumende ekukurukurirana, zvakadai sedhipatimendi re data, telegraph, foni, zvichingodaro. Nokukurumidza kwaiva nechinangwa chokubatanidza zvose zvinyorwa zvehurumende mune imwe, inonzi zita rinotevera: ISDN. Zvisinei, akakurumidza kukundikana. Uye pane zvikonzero zvakawanda zvezvikonzero izvi: mari yakakwirira yeIDN zvishandiso, kubuda kwemabasa matsva anodiwa, kukura kweIndaneti. Nokudaro, pakanga paine nhare itsva - NGN, yakavakwa pachishandiswa IP protocol.

Ndeapi mazano ekubatana kwemasangano akawanda evanhu vakawanda?

Izwi rinoparidzirwa kuburikidza nemagetsi ezera rinotevera rakapatsanurwa kuva chiratidzo uye mushandisi rudzi nerudzi rwayo. Yokutanga inopa humwe hutano uye inochengetedza kusinganzwisisiki kubhadhara kushanduka. Mushandisi anewo ruzivo runobatsira kumubhadhara (video, inzwi, data, nezvimwewo).

NGN yakabva pane teknolojia yePMLS, pamwe neInternet. Nhasi, nzira dzakatevera dzinotevera pakuvakwa kweNNN dzakasiyana:

1. H.323 ndiyo yekutanga yezvino inowanikwa. Inoratidzirwa se data inosungirirwa kuburikidza neIndaneti mitambo.

2. SIP yakasununguka nekutakura mitambo. H.323 yakatsiva H.323 apo matambudziko akawanda akawanikwa. SIP inopa VoIP services.

3. MGCP inokanganisa magedhi, ichiiputsa mumatatu matatu. Ichi Chiratidzo cheGedhi - inotumira mashoko ekuparidzira, Media Gateway - inotumira data yevashandi, Call Agent - ine inyanzvi yesuo.

Iyi nzira inogona kushandiswa pamwe chete pamwe chete.

SoftSwitch softswitch

Shanduro yeSoftwitch inotora mapurogiramu eVoIP, inopa hutano hwemakambani akange aripo nemazuva ano ePSTNs. Mutariri weGedhi, wakaitwa neH323-based Softswitch, uye Call Agent basa inoita kuti chigadzirwa chive chemazuva ano.

MGCF softswitch inoita basa rekushandisa uye packet switching.

Chii chiri NGN panguva ino?

Nekuwedzera, vatambi vekukurukurirana vari kutenderera ku packet switching. Inyanzvi itsva inobvumira kushanduka kusina kushanduka kubva kumaganho ezera rekare kusvika kune mazuva ano, kuve nekusimbisa kushandiswa kushanda mune imwe nhare yefoni. Nokudaro, kuitira kuti tisashandurwe zvachose chimiro chose chetereji, tinoda kushandisa iyi nheyo yenyaya yekuchinja. Zvinoda kuendeswa kune NGN:

- multimedia;

- Multiservice;

- Intelligence;

- multioperativeness;

- broadband;

- Scalability;

Invariance.

Ndiani anogadzira zvombo?

Vashandi veNNN ndivo makambani anotevera: Cisco Systems, Siemens, Alcatel-Lucent, Huawei, Avaya, etc. MuRussia - MFI Soft.

Iko kunewo ma multiservice cable makanda.

Multiservice network inobvumira mitambo yakawanda-terevhizheni terevhizheni, mavhidhiyo ekucherechedza mavhidhiyo, Indaneti yakakurumidza, kutumira data Ethernet, kuunganidza deta uye kutarirwa kwemashandi ekugadzirisa zvinhu zvebasa.

Multiservice cable cable inobvumira mitambo yekuparidzira mune chero chikamu chenyika, dunhu kana guta. Nokudaro, inoshandiswa nevakawanda makambani emichina.

Kuchinja mutsva kubva kumagetsi ekare kusvika kumagetsi ezuva ano kunoita kuti zvive nyore kugadzira chimwe chinhu chakakwana, chigadziriswa pasina kurasikirwa nemishandiro nemishonga. Panguva imwe chete, basa rekare rinogara, izvo zvinokosha kune vaterevhizheni.

Multiservice kukurukurirana manzwiro akawanda kupfuura kamwe chete achatifadza nechinhu chitsva, nokuti vane zvakawanda zvokukudziridza. Zvakanaka, kusvika panguva ino, NGN inopa mishandira iyo iyo yakanyanya kunyanya foni kana kambani yenhare inogona kupa.
