Ndipo chifukwa chakuti zinali zomvetsa kwambiri: kukwera mtengo kwa ISDN zida, zikamera wa ntchito yatsopano mwa anthu, chitukuko Intaneti IP. Choncho, pali zopezera watsopano - NGN, zomwe ndi zochokera protocol IP.

ndi mfundo za ntchito multiservice kulankhulana maukonde chiyani?

mfundo opatsirana kudzera m'badwo maukonde lotsatira, anagawa malinga ndi mtundu wawo ndi mbendera mwambo. Zoyambirira zina ndi kulola kusinthitsa yosalala olembetsa. wosuta amatipatsanso mfundo zothandiza wolembetsa ndi (video, mawu, deta, ndi zina zotero).

The NGN zachokera luso MPLS, komanso Internet. Masiku ano, pali njira zotsatirazi kumanga NGN:

1. H.323 - ali woyamba wa mitundu panopa alipo. Iwo anapereka mu mawonekedwe a deta anakuta kudzera ISDN.

2. SIP zimadalira pa umisiri zoyendera. N'kubweretsa H.323, pamene kuzindikiridwa angapo mavuto. SIP imapereka VoIP-ntchito.

3. MGCP zipata umabala kuwonongeka, kuswa iwo uko mu midadada atatu. Iwo Kulankhulana Polakwika - transmits kusonyeza zambiri, Media Polakwika - transmits deta wosuta, Itanani Mtumiki - lili Polakwika nzeru.

njira izi zikhoza kugwiritsidwa ntchito ponena ichitikire ndipo payokha.

- multioperativnost;

- burodibandi;

- scalability;

- invariance.

Mlengi zida ndi ndani?

Palinso Mipikisano utumiki Intaneti chingwe.

Maukonde multiservice amalola Mipikisano njira chingwe TV, njira video, liwilo internet, kufala deta Efaneti, kupeza deta ndi kulamulira metering zipangizo zofunikira.

Multiservice Chingwe Networks choti ukufalitsidwa njira mu gawo lirilonse la dziko, dera, mzinda. Choncho, ntchito ndi ntchito zambiri chingwe.

Latsopano kusintha kwa usinkhu kuti umisiri wamakono n'zotheka kuti kulenga chinachake chipangizo zambiri, nzeru popanda kutaya ndi ntchito zomwe zilipo kale ndi maofesi. Izi amapulumutsa ntchito akale, nkofunika kwa utumiki wosamalira.

Multiservice netiweki mobwerezabwereza timasangalala ndi chinthu chatsopano, chifukwa ali kwambiri kukulitsa. Koma lero NGN ntchito onse amene angapereke zotsogola telefoni kapena chingwe maukonde.
