Ibintu by'ingenzi

Ubushobozi bunini busangiwe 

Urukurikirane rwa MA5680T rutanga urubuga runini rusangiwe rushyigikira ubushobozi bwihuse bwo guhinduranya.

Yatejwe imbere ishingiye kumurongo wibikoresho bya iMAP hamwe na software ya IAS ya Huawei, serivise ya MA5680T ikoresha imyubakire igezweho.

Ubushobozi bwo guhinduranya indege yinyuma igera kuri 3.2 Tbit / s.

Ubushobozi bwo guhinduranya ibyerekezo byubuyobozi bugenzura bigera kuri 480 Gbit / s.

Ubuyobozi bwa GPBD bushigikira ibyambu umunani bya GPON naho subrack yose ishyigikira kugeza 8K ONT.

Ubuyobozi bwa EPBD bushigikira ibyambu umunani bya EPON.Ukurikije igipimo cyo gutandukana 1:64, subrack yose ishyigikira kugeza 8K ONT.

Kugabana urubuga rwiterambere hamwe nibikoresho byogukoresha umurongo mugari wa Huawei, serivise ya MA5680T ishyigikira umurongo wa 2 na Layeri 3 yibikoresho byogukoresha umurongo mugari kugirango utange ibikorwa-byerekanwa nabakoresha.

Ubushobozi bukomeye bwa GPON / EPON ubushobozi bwo kubona

1. Ubushobozi bwa EPON 

Ingingo kuri point-point (P2MP) yubatswe ikoreshwa mugushigikira pasiporo optique

kwanduza kuri Ethernet.Symmetrical upstream and downstream rates ya 1.25 Gbit / s irashyigikirwa mugutanga serivise yihuta ya serivise, ihura numuyoboro mugari

ibisabwa kubakoresha.

Mu cyerekezo cyo hasi, umurongo mugari usangirwa nabakoresha batandukanye mubanga

uburyo bwo gutangaza.Mu cyerekezo cyo hejuru, igihe cyo kugabana multiplex (TDM) ikoreshwa mugusangira umurongo.

Urukurikirane rwa MA5680T rushyigikira imbaraga zagutse (DBA) hamwe nubunini bwa 64 kbit / s.Kubwibyo, umurongo mugari wa ONT ukoresha urashobora gutangwa muburyo bushingiye kubakoresha.

Sisitemu ya EPON ikoresha tekinoroji ya optique yohereza, kandi optique itandukanya ikoresha uburyo bwa P2MP kandi ishyigikira igabana rya 1:64.

Intera yo gushyigikira intera igera kuri 20 km.

Ikirangantego cya tekinoroji gishobora kuba giteganijwe, cyikora, cyangwa icyiciro cya mbere.

Ubushobozi bwa GPON

Igipimo cyo hejuru kirashyigikiwe.Igipimo cyo hasi kigera kuri 2.488 Gbit / s naho igipimo cyo hejuru kigera kuri 1.244 Gbit / s.

Intera ndende irashyigikiwe.Intera ntarengwa yoherejwe na ONT ni 60 km.Intera igaragara hagati ya ONT ya kure na ONT yegereye irashobora kugera kuri 20 km.

Umubare munini wo gutandukana urashyigikiwe.Ikibaho 8-icyambu cya GPON gishyigikira igabanywa rya 1: 128, ryongera ubushobozi kandi rikabika ibikoresho bya fibre optique.

Ubucucike buri hejuru burashyigikiwe.Urukurikirane rwa MA5680T rutanga ibyambu 8 cyangwa ibyambu 4 bya GPON

kibaho kugirango yongere ubushobozi bwa sisitemu.

Imikorere ya H-QoS (ubuziranenge bwa serivisi) ishyigikiwe no guhura na SLA

ibisabwa kubakiriya batandukanye.

Ubushobozi bukomeye bwa QoS

Urukurikirane rwa MA5680T rutanga ibisubizo bikurikira QoS ibisubizo kugirango byorohereze

imicungire ya serivisi zitandukanye:

Shyigikira ibyihutirwa (bishingiye ku cyambu, aderesi ya MAC, aderesi ya IP, indangamuntu ya TCP, cyangwa icyambu cya UDP), gushushanya mbere no guhindura bishingiye ku murima wa ToS na 802.1p, na serivisi zitandukanye za DSCP.

Gushyigikira umurongo mugari (ukurikije icyambu, aderesi ya MAC, aderesi ya IP, indangamuntu ya TCP, cyangwa

Icyambu cya UDP) hamwe nubugenzuzi bwa 64 kbit / s.

Shyigikira uburyo butatu bwo gutondekanya umurongo: umurongo wambere (PQ), uburemere bwa robin (WRR), na PQ + WRR.

Shyigikira HQoS, yizeza umurongo wa serivise nyinshi kubakoresha benshi: Urwego rwa mbere rwemeza umukoresha umurongo, naho urwego rwa kabiri rwemeza umurongo wa buri serivisi ya buri mukoresha.Ibi byemeza ko umurongo wizewe watanzwe rwose kandi umurongo wagutse wagabanijwe neza.

Ingamba zuzuye zo kwishingira umutekano

Urukurikirane rwa MA5680T rwujuje ibyangombwa bisabwa byumutekano wa serivisi zitumanaho, gukoresha byimazeyo protocole yumutekano, no kurinda byimazeyo umutekano wa sisitemu nuyikoresha.

1. Igipimo cyumutekano wa sisitemu

Kurinda igitero cya DoS (guhakana serivisi)

MAC (kugenzura itangazamakuru) kugenzura aderesi

Igitero cyo kurwanya anti-ICMP / IP

Inkomoko ya aderesi yerekana inzira

Urutonde

2. Igipimo cyumutekano wabakoresha

DHCP (Dynamic Host Configuration Protocol) Ihitamo 82 kugirango uzamure umutekano wa DHCP

Guhuza hagati ya MAC / IP aderesi hamwe nicyambu

Kurwanya anti-MAC no kurwanya IP

Kwemeza bishingiye kuri numero yuruhererekane (SN) nijambobanga rya ONU / ONT

Inshuro eshatu

Guhishira amakuru yoherejwe muri GPON icyerekezo cyo hasi kubakoresha batandukanye,

nka AES (ibanga ryambere ryibanga) 128-bitobora

Ubwoko bwa GPON B OLT gutaha kabiri

Ihuza ryubwenge kandi ukurikirane ihuza ryumuyoboro ufite imiyoboro ibiri yo hejuru

Imiterere ihindagurika ya topologiya

Nka porogaramu nyinshi yo kugera kuri serivise, urutonde rwa MA5680T rushyigikira uburyo bwinshi bwo kugera hamwe na topologiya ya topologiya kugirango uhuze abakoresha topologiya ibisabwa kubitandukanye.

ibidukikije na serivisi.

Igishushanyo mbonera cyabatwara

Sisitemu yo kwizerwa ya serivise ya MA5680T yitabwaho muri sisitemu,

ibyuma, hamwe na software ishushanya kugirango igikoresho gikore muburyo busanzwe.Uwiteka
