Fahimtar BNG
Broadband Network Gateway (BNG) ita ce hanyar shiga ga masu biyan kuɗi, ta inda suke haɗi zuwa hanyar sadarwar tarho. Lokacin da aka kafa haɗin kai tsakanin BNG da Kayan Aikin Kaya na Abokin Ciniki (CPE), mai biyan kuɗi zai iya samun damar yin amfani da sabis na watsa shirye-shiryen da Sabis na Sadarwa (NSP) ko Mai Ba da Sabis na Intanet (ISP) ke bayarwa.
BNG yana kafa da sarrafa zaman masu biyan kuɗi. Lokacin da zama ke aiki, BNG yana tara zirga-zirga daga zaman masu biyan kuɗi daban-daban daga hanyar sadarwar shiga, kuma ta tura shi zuwa cibiyar sadarwar mai bada sabis.
BNG mai bada sabis ne ke tura shi kuma yana nan a farkon haɗuwa a cikin hanyar sadarwa, kamar na'ura mai ba da hanya tsakanin hanyoyin sadarwa. Na'ura mai ba da hanya tsakanin hanyoyin sadarwa, kamar Cisco ASR 9000 Series Router, yana buƙatar daidaita shi don yin aiki azaman BNG. Saboda mai biyan kuɗi yana haɗa kai tsaye zuwa na'ura mai ba da hanya tsakanin hanyoyin sadarwa, BNG yadda ya kamata yana sarrafa damar masu biyan kuɗi, da ayyukan sarrafa masu biyan kuɗi kamar:
- Tabbatarwa, izini da lissafin zaman masu biyan kuɗi
- Ayyukan adireshi
- Tsaro
- Gudanar da manufofin
- Ingancin Sabis (QoS)
Wasu fa'idodin amfani da BNG sune:
- Na'ura mai ba da hanya tsakanin hanyoyin sadarwa ta BNG ba kawai tana yin aikin tuƙi ba har ma tana sadarwa tare da sabar tabbaci, izini, da lissafin kuɗi (AAA) don aiwatar da ayyukan gudanarwa da lissafin kuɗi. Wannan yana sa maganin BNG ya zama cikakke.
- Ana iya samar da masu biyan kuɗi daban-daban sabis na cibiyar sadarwa daban-daban. Wannan yana bawa mai bada sabis damar keɓance fakitin faɗaɗa don kowane abokin ciniki dangane da bukatunsu.
BNG Architecture
Manufar tsarin gine-ginen BNG shine don ba da damar na'ura mai ba da hanya tsakanin hanyoyin sadarwa na BNG don yin hulɗa tare da na'urori na gefe (kamar CPE) da sabar (kamar AAA da DHCP), don samar da haɗin yanar gizo ga masu biyan kuɗi da gudanar da zaman masu biyan kuɗi. Ana nuna ainihin gine-ginen BNG a wannan adadi.
Hoto 1: BNG Architecture
An tsara gine-ginen BNG don yin waɗannan ayyuka:
- Haɗawa tare da Kayan Aikin Katin Abokin Ciniki (CPE) wanda ke buƙatar ba da sabis na faɗaɗa.
- Ƙirƙirar zaman masu biyan kuɗi ta amfani da ka'idojin IPoE ko PPPoE.
- Yin hulɗa tare da uwar garken AAA wanda ke tabbatar da masu biyan kuɗi, da kuma adana asusun zaman masu biyan kuɗi.
- Yin hulɗa tare da uwar garken DHCP don samar da adireshin IP ga abokan ciniki.
- Tallan hanyoyin biyan kuɗi.
Ayyukan BNG guda biyar an yi bayani a taƙaice a cikin sassan masu zuwa.
Haɗa tare da CPE
BNG yana haɗa zuwa CPE ta hanyar Multixer da Ƙofar Gida (HG). CPE tana wakiltar sabis ɗin wasa sau uku a cikin sadarwa, wato, murya (waya), bidiyo (saitin babban akwatin), da bayanai (PC). Na'urorin masu biyan kuɗi guda ɗaya suna haɗi zuwa HG. A cikin wannan exampHar ila yau, mai biyan kuɗi ya haɗa zuwa cibiyar sadarwa ta hanyar haɗin Layin Subscriber Dijital (DSL). Saboda haka, HG yana haɗi zuwa DSL Access Multiplexer (DSLAM).
HGs da yawa na iya haɗawa zuwa DSLAM guda ɗaya wanda ke aika cunkoson ababen hawa zuwa na'ura mai ba da hanya tsakanin hanyoyin sadarwa BNG. Na'ura mai ba da hanya tsakanin hanyoyin sadarwa ta BNG tana tafiyar da zirga-zirga tsakanin na'urori masu nisa na broadband (kamar DSLAM ko Ethernet Aggregation Switch) da cibiyar sadarwar mai bada sabis.
Ƙirƙirar Zama Masu Biyan Kuɗi
Kowane mai biyan kuɗi (ko fiye da musamman, aikace-aikacen da ke gudana akan CPE) yana haɗa zuwa cibiyar sadarwar ta hanyar ma'ana. Dangane da ƙa'idar da aka yi amfani da ita, zaman masu biyan kuɗi an kasasu zuwa nau'i biyu:
- PPPoE zaman masu biyan kuɗi-An kafa zaman mai biyan kuɗi na PPP akan Ethernet (PPPoE) ta amfani da ka'idar batu-zuwa (PPP) wacce ke gudana tsakanin CPE da BNG.
- zaman masu biyan kuɗi na IPoE-An kafa zaman taron masu biyan kuɗi na IP akan Ethernet (IPoE) ta amfani da ka'idar IP wanda ke gudana tsakanin CPE da BNG; Ana yin adireshin IP ta amfani da ka'idar DHCP.
Yin hulɗa tare da RADIUS Server
BNG ya dogara da uwar garken Dial-In User Service (RADIUS) na waje don samar da ayyukan tantance masu biyan kuɗi, Izini, da Lissafi (AAA). A lokacin aikin AAA, BNG yana amfani da RADIUS zuwa:
- Tabbatar da mai biyan kuɗi kafin kafa zaman biyan kuɗi
- ba da izini ga mai biyan kuɗi don samun dama ga takamaiman sabis na cibiyar sadarwa ko albarkatu
- bin diddigin amfani da sabis na broadband don lissafin kuɗi ko lissafin kuɗi
Sabar RADIUS ta ƙunshi cikakkun bayanai na duk masu biyan kuɗi na mai bada sabis, kuma tana ba da sabuntawar bayanan masu biyan kuɗi zuwa BNG a cikin nau'ikan halaye a cikin saƙonnin RADIUS. BNG, a gefe guda, yana ba da bayanan amfani da zaman (lissafin) ga uwar garken RADIUS. Don ƙarin bayani game da halayen RADIUS, duba Halayen RADIUS.
BNG yana goyan bayan haɗin kai tare da sabar RADIUS fiye da ɗaya don samun gazawa akan aikin AAA. Domin misaliample, idan uwar garken RADIUS A yana aiki, to BNG tana jagorantar duk saƙonni zuwa uwar garken RADIUS A. Idan sadarwa tare da uwar garken RADIUS A ta ɓace, BNG tana tura duk saƙonni zuwa uwar garken RADIUS B.
A yayin mu'amala tsakanin sabar BNG da RADIUS, BNG tana aiwatar da daidaita nauyi ta hanyar zagaye-zagaye. Yayin aiwatar da daidaita nauyin kaya, BNG tana aika buƙatun sarrafa AAA zuwa uwar garken RADIUS A kawai idan yana da bandwidth don yin aiki. In ba haka ba, ana aika buƙatar zuwa uwar garken RADIUS B.
Yin hulɗa tare da uwar garken DHCP
BNG ya dogara da uwar garken Kanfigareshan Kanfigareshan Mai watsa shiri na waje (DHCP) don rarraba adireshi da ayyukan daidaitawar abokin ciniki. BNG na iya haɗawa zuwa uwar garken DHCP fiye da ɗaya don samun gazawa akan sakewa a tsarin yin magana. Sabar DHCP tana ƙunshe da wurin waha mai adireshi na IP, daga inda take rarraba adireshi zuwa CPE.
Yayin hulɗar tsakanin BNG da uwar garken DHCP, BNG yana aiki azaman mai ba da sanda ta DHCP ko DHCP wakili.
A matsayinsa na DHCP, BNG yana karɓar watsa shirye-shiryen DHCP daga abokin ciniki CPE, kuma yana tura buƙatar zuwa uwar garken DHCP.
A matsayin wakili na DHCP, BNG da kanta tana kula da wuraren adireshin ta hanyar samo shi daga uwar garken DHCP, sannan kuma tana sarrafa hayar adireshin IP. BNG yana sadarwa akan Layer 2 tare da abokin ciniki Home Gateway, kuma akan Layer 3 tare da sabar DHCP.
DSLAM tana gyara fakitin DHCP ta hanyar shigar da bayanan tantance masu biyan kuɗi. BNG tana amfani da bayanan ganowa da DSLAM ta saka, da adireshin da uwar garken DHCP ta sanya, don gano mai biyan kuɗi akan hanyar sadarwa, da saka idanu kan yarjejeniyar hayar adireshin IP.
Hanyoyin Tallace-tallacen Abokin Ciniki
Don ingantacciyar aiki a cikin hanyoyin ƙira inda Ƙofar Ƙofar Border (BGP) ke tallata hanyoyin biyan kuɗi, BNG tana tallata duk rukunin yanar gizon da aka keɓance ga masu biyan kuɗi ta amfani da umarnin hanyar sadarwa a cikin tsarin BGP.
BNG yana sake rarraba hanyoyin masu biyan kuɗi ɗaya kawai a cikin yanayin yanayi inda uwar garken Radius ke ba da adireshin IP ga mai biyan kuɗi kuma babu wata hanyar sanin wane BNG ce ta musamman mai biyan kuɗi zai haɗa.
Matsayin BNG a cikin Samfuran hanyar sadarwa na ISP
Matsayin BNG shine ƙaddamar da zirga-zirga daga mai biyan kuɗi zuwa ISP. Hanyar da BNG ta haɗa zuwa
ISP ya dogara da samfurin hanyar sadarwar da yake ciki. Akwai nau'ikan ƙirar hanyar sadarwa iri biyu:
- Mai Ba da Sabis na hanyar sadarwa, a shafi na 5
- Shiga Mai Bayar da hanyar sadarwa, a shafi na 5
Mai Bayar da Sabis na Yanar Gizo
Hoto mai zuwa yana nuna yanayin yanayin tsarin Mai Ba da Sabis na Sadarwa.
A cikin tsarin Mai ba da Sabis na hanyar sadarwa, ISP (wanda ake kira dillali) yana ba da haɗin kai tsaye zuwa mai biyan kuɗi. Kamar yadda aka nuna a cikin wannan adadi na sama, BNG yana a gefen na'ura mai ba da hanya tsakanin hanyoyin sadarwa, kuma aikinsa shine haɗi zuwa cibiyar sadarwa ta hanyar haɗin kai.
Shiga Mai Bayar da hanyar sadarwa
Hoton da ke gaba yana nuna yanayin yanayin tsarin Samfuran hanyar sadarwa.
A cikin tsarin Mai ba da hanyar sadarwa ta hanyar sadarwa, mai ɗaukar hanyar sadarwa (wanda ake kira wholesaler) ya mallaki ababen more rayuwa na cibiyar sadarwa, kuma yana ba da haɗin yanar gizo ga mai biyan kuɗi. Duk da haka, mai ɗaukar hanyar sadarwa ba ya mallaki cibiyar sadarwa na broadband. Madadin haka, mai ɗaukar hanyar sadarwa yana haɗawa zuwa ɗaya daga cikin ISPs waɗanda ke sarrafa hanyar sadarwar watsa labarai.
Mai ɗaukar hanyar sadarwa ne ke aiwatar da BNG kuma aikinsa shine mika zirga-zirgar masu biyan kuɗi zuwa ɗaya daga cikin ISPs da yawa. Aikin kashe hannu, daga mai ɗaukar kaya zuwa ISP, ana aiwatar da shi ta hanyar Layer 2 Tunneling Protocol (L2TP) ko Layer 3 Virtual Private Networking (VPN). L2TP yana buƙatar ɓangarori biyu na hanyoyin sadarwa:
- L2TP Access Concentrator (LAC) — BNG ne ke samar da LAC.
- Sabar hanyar sadarwa ta L2TP (LNS) - ISP ne ke samar da LNS.
