Ziziphi iingenelo zinika network unxibelelwano multiservice?

Elinye igama lothungelwano multiservice - NGN, leyo ziguqulelwe IsiNgesi kuvakala ngathi New Generation Networks okanye Next Generation Network. uthungelwano Multiservice yonxibelelwano - uthungelwano isizukulwana noveshego. Ongundoqo uthungelwano IP-based ezixhasa uluhlu buso okanye olupheleleyo lweenkonzo ilizwi edingeka kakhulu, multimedia kunye data. uthungelwano zonxibelelwano Multiservice asebenza kwi-siseko ukuhlangabezana iinkonzo lomnxeba.

Nto leyo eyayifuneka ukuze ukuvela NGN?

Ngaphambili, ulwazi ezahlukeneyo sisasazwa abasebenzisa iiwebhsayithi zokunxibelelana yesebe, ezifana kwinethiwekhi ukudluliselwa data, yocingo, yomnxeba njalo njalo. Kungekudala kwabakho ingcamango yokuhlanganisa lonke unxibelelwano lwesebe ngaso omnye, ogama ngolu hlobo lulandelayo: ISDN. Noko ke, yena akuphumelelanga. Kwaye izizathu mhaka kwakunzima kakhulu: iindleko eziphezulu izixhobo ISDN, ukuvela iinkonzo ezintsha kwemfuno, uphuhliso lothungelwano IP. Ngoko ke, kukho kwinethiwekhi - NGN, ehlanganisiweyo esusela kwi-IP protocol.

Yintoni na le migaqo zomsebenzi womnatha unxibelelwano multiservice?

Ulwazi ithunyelwe nge womnatha elilandelayo isizukulwana, zahlulwe uhlobo lwabo uphawu eqhelekileyo. Okokuqala inika iinkonzo ezithile kwaye yenza utshintshe nje kakuhle lwababhalisi. Umsebenzisi kwakhona inika iinkcukacha luncedo isikhokhelo (ividiyo, ilizwi, idatha, njalo njalo).

I NGN kusekelwe kwiteknoloji ephalamende, kwakunye Internet. Namhlanje, kukho iindlela zilandelayo yokwakhiwa NGN:

1. H.323 - lowo wokuqala iintlobo ezikhoyo ngoku. It linikwa kwi uhlobo lwe data eyalekeneyo nge ISDN.

2. SIP izimele ubugcisa zothutho. Asusa H.323, xa ngokwenyani ichonge iingxaki. SIP inika VoIP-nkonzo.

3. kwama MGCP uvelisa ukonakala, ukuqhekeza kubahlisela iibhloko ezintathu. It zokubonisa Gateway - adlulisele kuye umqondiso ulwazi, Media Gateway - lokudlulisa yomsebenzisi, Tsalela uMmeli - iqulethe i-Gateway intelligence.

Ezi nkqubo kusetyenziswe zombini ngokudibeneyo kwaye ngokwahlukeneyo.

Softswitch SoftSwitch

Softswitch elawula leeseshoni VoIP, inika uthungelwano ekhoyo unxibelelwano kunye PSTN mihla. umsebenzi Umlindi eyenziwa Softswitch esekelwe h323, kwaye osemqoka Call Agent yenza isixhobo mihla.

Softswitch MGCF owenza umsebenzi wonxibelelwano umjelo kunye lwepakethi utshintshayo.

Yintoni na le NGN ngalo mzuzu?

Iya isanda, abaqhubi kokutshintshela ngepakethi utshintshayo. ubugcisa ezintsha kwenza kube lula ukuswitsha ukuhlanganiswa ukusuka ekuqaleni ukuya uthungelwano kwisizukulwana mihla, ukuqinisekisa ukusebenza rhoqo nayiphi kwenethiwekhi yefowuni. Ngoko ke akwenzi ngokwesiseko ukutshintsha lonke isakhiwo uthungelwano, kufuneka basebenzise eli xesha umgaqo yenguqu. Iimfuneko shintsha ukuba NGN:

- Multimedia;

- multiservice;

- zobuntlola;

- multioperativnost;

- Broadband;

- scalability;

- olungaguqukiyo.

Ngubani na umenzi kwezixhobo?

Kubavelisi NGN ezi iinkampani zilandelayo: Sisco Systems, Siemens, Alcatel-Lucent, Huawei, Avaya kunye nabanye e Russia - MFI Soft ..

Kukho kwakhona uthungelwano intambo multi-nkonzo.

Uthungelwano multiservice ivumela multi-channel cable TV, imijelo ividiyo, ngesantya esiphezulu-intanethi, ukudluliselwa data Ethernet, ukufumana iinkcukacha kunye nokulawulwa kwezixhobo yolinganiso ukulungiselela eziluncedo.

Multiservice Cable Networks avumela ukusasaza imijelo kuyo nayiphi na inxalenye lizwe, kummandla, umzi. Ngoko ke, oku kusetyenziswa ngabaqhubi intambo abaninzi.

zinakho ezintsha ukusuka endala ubuchwepheshe bale mihla kwenza kube lula ukwenza into nobunzima kakhulu, izinto ezintsha ngaphandle kokulahlekelwa iinkonzo nezibonelelo ezikhoyo. Oku kugcina imisebenzi ubudala, kubalulekile ukuba ababoneleli ngeenkonzo.

Multiservice uqhagamshelo kwinethiwekhi kwakhona kwaye kwakhona ukuziyolisa nathi into entsha, kuba kuninzi ukuphuhlisa. Kodwa namhlanje NGN linikezela zonke iinkonzo onokusinika ngomnxeba okanye intambo womnatha kakhulu.
