Zofunika Kwambiri

nsanja yogawana zambiri 

Mndandanda wa MA5680T umapereka nsanja yogawana mphamvu zambiri zomwe zimathandizira kusinthasintha kothamanga kwambiri.

Wopangidwa kutengera nsanja ya iMAP hardware ndi nsanja ya pulogalamu ya IAS ya Huawei, mndandanda wa MA5680T umatenga zomanga ndi mapangidwe apamwamba.

Kuthekera kosinthira kwa ndege yakumbuyo kumafikira 3.2 Tbit / s.

Mphamvu yosinthira pawiri ya bolodi yowongolera ndikufika ku 480 Gbit/s.

Gulu la GPBD limathandizira madoko asanu ndi atatu a GPON ndipo subrack yonse imathandizira mpaka 8K ONTs.

Gulu la EPBD limathandizira madoko asanu ndi atatu a EPON.Kutengera kugawanika kwa 1:64, subrack yonse imathandizira mpaka 8K ONTs.

Kugawana nsanja yachitukuko ndi zida za Huawei zofikira pa burodibandi, mndandanda wa MA5680T umathandizira mawonekedwe a Layer 2 ndi Layer 3 pazida zolumikizirana ndi burodibandi kuti apereke ntchito zongogwiritsa ntchito komanso zamtsogolo.

Kuthekera kophatikizana kwa GPON/EPON

1. Kuthekera kwa EPON 

Zomangamanga zamitundu yambiri (P2MP) zimagwiritsidwa ntchito kuthandizira mawonekedwe osawoneka

kutumiza kudzera pa Ethernet.Ma Symmetrical kumtunda ndi kutsika kwa 1.25 Gbit/s amathandizidwa kuti apereke ntchito zothamanga kwambiri, kukwaniritsa bandwidth.

zofunikira za ogwiritsa ntchito.

Kumbali yakutsika, bandwidth imagawidwa ndi ogwiritsa ntchito osiyanasiyana mu encrypted

njira yowulutsira.Kumtunda kwamtunda, nthawi yogawanika multiplex (TDM) imagwiritsidwa ntchito kugawana bandwidth.

Mndandanda wa MA5680T umathandizira kugawa kwa bandwidth (DBA) ndi granularity ya 64 kbit/s.Chifukwa chake, bandwidth ya ogwiritsa ntchito ma terminal a ONT atha kugawidwa mwachangu kutengera zomwe ogwiritsa ntchito akufuna.

Dongosolo la EPON limagwiritsa ntchito ukadaulo wopatsirana wopatsa mphamvu, ndipo chowotcha chamagetsi chimagwiritsa ntchito mawonekedwe a P2MP ndikuthandizira kugawanika kwa 1:64.

Mtunda wotumizira wothandizidwa ndi mpaka 20 km.

Ukadaulo wosiyanasiyana ukhoza kukonzedwa mosiyanasiyana, wongoyambira, kapena woyambira.

Kuthekera kwa GPON

Mtengo wapamwamba umathandizidwa.Kutsika kwamadzi kumafika ku 2.488 Gbit/s ndipo kumtunda kwa mtsinje kumafika ku 1.244 Gbit/s.

Mtunda wautali umathandizidwa.Mtunda wopitilira muyeso wamtundu wa ONT ndi 60 km.Mtunda wapakati pakati pa ONT yakutali kwambiri ndi ONT yapafupi ukhoza kukhala 20 km.

Kugawanika kwakukulu kumathandizidwa.Gulu lofikira la 8-port GPON limathandizira kugawanika kwa 1:128, komwe kumawonjezera mphamvu ndikusunga zida za fiber.

High kachulukidwe amathandizidwa.Mndandanda wa MA5680T umapereka mwayi wa GPON wa madoko 8 kapena 4

board kuti muwonjezere mphamvu ya dongosolo.

Ntchito ya H-QoS (hierarchical quality of service) imathandizidwa kuti ikwaniritse SLA

zofunika za makasitomala osiyanasiyana amalonda.

Mphamvu ya QoS

Mndandanda wa MA5680T umapereka mayankho amphamvu awa a QoS kuti athandizire

kasamalidwe ka ntchito zosiyanasiyana:

Imathandizira kuyang'anira patsogolo (kutengera doko, adilesi ya MAC, adilesi ya IP, ID ya doko la TCP, kapena ID ya doko la UDP), kupanga mapu ndikusintha kutengera gawo la ToS ndi 802.1p, ndi ntchito zosiyanitsa za DSCP.

Imathandizira kuwongolera kwa bandwidth (kutengera doko, adilesi ya MAC, adilesi ya IP, ID ya doko la TCP, kapena

UDP port ID) yokhala ndi granularity yowongolera 64 kbit/s.

Imathandizira mitundu itatu yokonzekera mizere: mzere woyamba (PQ), robin yolemetsa (WRR), ndi PQ + WRR.

Imathandizira HQoS, yomwe imatsimikizira kuchuluka kwa mautumiki kwa ogwiritsa ntchito angapo: Gawo loyamba limatsimikizira bandwidth ya wogwiritsa ntchito, ndipo gawo lachiwiri limatsimikizira bandwidth pa ntchito iliyonse ya wogwiritsa ntchito aliyense.Izi zimatsimikizira kuti bandwidth yotsimikizika imaperekedwa mwamtheradi ndipo bandwidth yophulika imaperekedwa moyenera.

Njira zotsimikizira chitetezo chokwanira

Mndandanda wa MA5680T umakwaniritsa zofunikira zachitetezo cha ma telecommunication, gwiritsani ntchito ndondomeko zachitetezo, ndikuwonetsetsa chitetezo chadongosolo ndi wogwiritsa ntchito.

1. System chitetezo muyeso

Chitetezo ku DoS (kukana ntchito).

MAC (media access control) kusefa adilesi

Anti-ICMP/IP paketi kuwukira

Kusefa kwamaadiresi kochokera
