Ibisobanuro bya tekiniki bya huawei ma5680t gpon olt byakozwe na huawei ma5680 olt

Ibiranga by'ingenzi

Urubuga runini rusangiwe rufite ubushobozi bunini 

Uruhererekane rwa MA5680T rutanga urubuga runini ruhuza ubushobozi bwo guhinduranya ibintu rwihuta cyane.

Yakozwe hashingiwe ku rubuga rwa iMAP na porogaramu ya IAS ya Huawei, uruhererekane rwa MA5680T rukoresha imiterere n'ubuhanga buhanitse.

Ubushobozi bwo guhinduranya bw'inyuma bugera kuri 3.2 Tbit/s.

Ubushobozi bwo guhinduranya icyerekezo cy'ibiri by'ikibaho cyo kugenzura bugera kuri 480 Gbit/s.

Ishyirahamwe rya GPBD rishyigikira ibyambu umunani bya GPON naho igice cyose gishyigikira ibyuma bigera kuri 8K ONTs.

Ikarita ya EPBD ishyigikira imiyoboro umunani ya EPON. Hashingiwe ku gipimo cya 1:64 cy'igabanywa, subrack yose ishyigikira imiyoboro igera kuri 8K ONTs.

Isangiye urubuga rwo guteza imbere ibikoresho byo gukoresha interineti bya Huawei, uruhererekane rwa MA5680T rushyigikira imiterere ya Layer 2 na Layer 3 y'ibikoresho byo gukoresha interineti kugira ngo bitange imikorere ijyanye n'abakoresha n'iy'ejo hazaza.

Ubushobozi bukomeye bwo kugera kuri GPON/EPON buhujwe

1. Ubushobozi bwo kugera kuri EPON 

Imiterere ya point to multi-point (P2MP) ikoreshwa mu gushyigikira ikoranabuhanga ritagaragara

Kohereza ubutumwa kuri Ethernet. Igipimo cy’ikoranabuhanga cya 1.25 Gbit/s gishyigikiwe kugira ngo gitange serivisi za interineti yihuta cyane, ihuye n’uburyo bwa interineti

ibisabwa n'abakoresha uburyo bwo kwinjira.

Mu cyerekezo cyo hasi, bandwidth isangiwe n'abakoresha batandukanye mu buryo bwa "encrypted"

Uburyo bwo gusakaza. Mu cyerekezo cyo hejuru, igabanywa ry'igihe (TDM) rikoreshwa mu gusangira bandwidth.

Uruhererekane rwa MA5680T rushyigikira uburyo bwo gutanga bandwidth ihindagurika (DBA) hamwe n'ubugari bwa kbit/s 64. Kubwibyo, bandwidth y'abakoresha terminal ya ONT ishobora gutangwa hakurikijwe ibisabwa n'abakoresha.

Sisitemu ya EPON ikoresha ikoranabuhanga rya "passive optical transmission", naho "optical splitter" ikoresha uburyo bwa P2MP kandi igashyigikira "split ratio" ya 1:64.

Intera yo kohereza ubutumwa ishyigikiwe ni uburebure bwa kilometero 20.

Ikoranabuhanga ryo gupima rishobora kuba intera iri ku murongo, intera yikora, cyangwa intera y'ibanze.

Ubushobozi bwo kwinjira muri 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 yo kohereza ubutumwa bwa ONT ni kilometero 60. Intera isanzwe iri hagati ya ONT iri kure cyane na ONT iri hafi ishobora kugera kuri kilometero 20.

Igipimo cyo kugabanyuka kiri hejuru kirashyigikiwe. Ikibaho cyo kwinjiramo cya GPON gifite imiyoboro 8 gishyigikira igipimo cyo kugabanyuka cya 1:128, ibyo byongera ubushobozi kandi bikarinda umutungo wa fibre optique.

Ubucucike buri hejuru bushyigikiwe. Uruhererekane rwa MA5680T rutanga uburenganzira bwo kugera kuri GPON ifite imiyoboro 8 cyangwa imiyoboro 4

ikibaho kugira ngo hongerwe ubushobozi bwa sisitemu.

Imikorere ya H-QoS (urwego rw'ireme rya serivisi) ishyigikiwe kugira ngo ihuze na SLA

ibisabwa n'abakiriya batandukanye b'ubucuruzi.

Ubushobozi bukomeye bwa QoS

Uruhererekane rwa MA5680T rutanga ibisubizo bikomeye bya QoS bikurikira kugira ngo byorohereze

imicungire ya serivisi zitandukanye:

Ishyigikira uburyo bwo kugenzura ibintu mbere y’igihe (ishingiye ku muyoboro, aderesi ya MAC, aderesi ya IP, indangamuntu ya TCP, cyangwa indangamuntu ya UDP), igenamiterere ry’ibintu mbere y’igihe no guhindura ishingiye ku rubuga rwa ToS na 802.1p, na serivisi za DSCP zitandukanye.

Ishyigikira kugenzura umuyoboro wa interineti (ishingiye kuri pouteur, aderesi ya MAC, aderesi ya IP, indangamuntu ya pouteur ya TCP, cyangwa

UDP port ID) ifite ubunini bw'igenzura bwa 64 kbit/s.

Ishyigikira uburyo butatu bwo guteganya umurongo: umurongo w'ibanze (PQ), robin zungurutse ifite uburemere (WRR), na PQ + WRR.

Ishyigikira HQoS, yemeza ko umuyoboro wa serivisi nyinshi uboneka ku bakoresha benshi: Urwego rwa mbere rwemeza umuyoboro wa interineti w’umukoresha, naho urwego rwa kabiri rwemeza umuyoboro wa interineti w’umukoresha wese. Ibi byemeza ko umuyoboro wa interineti wemewe uboneka burundu kandi umuyoboro wa interineti w’umukoresha wose uboneka neza.

Ingamba zihamye zo kugenzura umutekano

Uruhererekane rwa MA5680T rwujuje ibisabwa mu mutekano wa serivisi z'itumanaho, rukoresha byimazeyo amabwiriza y'umutekano, kandi rugenzura byimazeyo umutekano wa sisitemu n'umukoresha.

1. Ingamba z'umutekano wa sisitemu

Uburinzi ku gitero cya DoS (kwanga serivisi)

Gushungura aderesi za MAC (uburyo bwo kugenzura uburyo bwo kwinjira mu itangazamakuru)

Igitero cya Anti-ICMP/IP packet

Gushungura inzira z'aderesi z'isoko

Urutonde rw'ababura

2. Ingamba z'umutekano w'umukoresha

Uburyo bwa DHCP (Dynamic Host Configuration Protocol) 82 bwo kunoza umutekano wa DHCP

Guhuza aderesi za MAC/IP na ports

Kurwanya MAC no kurwanya IP

Kwemeza hashingiwe kuri nimero y'uruhererekane (SN) n'ijambo ry'ibanga bya ONU/ONT

Uburyo bwo gufunga inshuro eshatu

Kohereza ubutumwa bwa elegitoroniki mu cyerekezo cya GPON ku bakoresha batandukanye,

nka AES (igipimo cyo gukingira kigezweho) gukingira biti 128

Ihuza ry'ubwenge n'ihuza ry'umuyoboro w'itumanaho rifite imiyoboro ibiri izamuka

Topology y'urusobe rw'itumanaho rihindagurika

Nk'urubuga rwo kugera kuri serivisi nyinshi, uruhererekane rwa MA5680T rushyigikira uburyo bwinshi bwo kugera kuri interineti n'imiterere myinshi y'itumanaho kugira ngo ruhuze n'ibisabwa n'imiterere y'itumanaho ry'abakoresha ku buryo butandukanye.

ibidukikije na serivisi.

Igishushanyo mbonera cy’ubwirinzi bw’urwego rw’imodoka

Kwizerwa kwa sisitemu ya MA5680T ni byo byitabwaho muri sisitemu,

ibikoresho bya elegitoroniki, n'imiterere ya porogaramu kugira ngo igikoresho kigende neza uko gisanzwe.
