Kugona kwakasimba kweGPON/EPON kwakabatanidzwa

1. Kugona kuwana EPON 

Magadzirirwo ePoint to Multi-Point (P2MP) anoshandiswa kutsigira passive optical

kutapurirana kuburikidza neEthernet. Mwero we1.25 Gbit/s unotsigirwa kuti upe masevhisi eBroadband anomhanya zvakanyanya, zvichizadzisa bandwidth.

zvinodiwa nevashandisi vekushandisa mukana.

Munzira yekudzika, bandwidth inogovaniswa nevashandisi vakasiyana mu encrypted

nzira yekuparadzira. Munzira yekukwira, nguva yekupatsanura multiplex (TDM) inoshandiswa kugovera bandwidth.

MA5683T series inotsigira dynamic bandwidth allocation (DBA) ine granularity ye64 kbit/s. Nokudaro, bandwidth yevashandisi veONT terminal inogona kugoverwa zvinoenderana nezvinodiwa nemushandisi.

Sisitimu yeEPON inoshandisa tekinoroji yekutumira ma "passive optical transmission", uye "optical splitter" inoshandisa P2MP mode uye inotsigira "split ratio" ye1:64.

Nhanho yekutakurwa kwegetsi inotsigirwa inosvika makiromita makumi maviri.

Tekinoroji yekuparadzanisa inogona kuva kuronga kupatsanura, otomatiki kupatsanura, kana kutanga kupatsanura.

Kugona kuwana GPON

Mutengo wepamusoro unotsigirwa. Mutengo wepasi unosvika 2.488 Gbit/s uye mutengo wepamusoro unosvika 1.244 Gbit/s.

Kureba kunotsigirwa. Kureba kwakanyanya kwekutumira kweONT imakiromita makumi matanhatu. Kureba pakati peONT iri kure neONT iri pedyo kunogona kusvika makiromita makumi maviri.

Chiyero chekupatsanura chakakwirira chinotsigirwa. Bhodhi reGPON rine maport masere rinotsigira chiyero chekupatsanura che1:128, izvo zvinowedzera kugona uye zvinochengetedza zviwanikwa zve fiber ye optical.

Kuwanda kwehuwandu hwepamusoro kunotsigirwa. MA5683T series inopa mukana wekuwana GPON ine maports masere kana mana

bhodhi rekuwedzera kugona kwesystem.

Basa reH-QoS (hierarchical quality of service) rinotsigirwa kuti risangane neSLA

zvinodiwa nevatengi vakasiyana-siyana vemabhizinesi.

Kugona kweQoS kwakasimba

Mapurogiramu eMA5683T anopa mhinduro dzinotevera dzeQoS dzakasimba kuti zvive nyore

manejimendi emabasa akasiyana-siyana:

Inotsigira prioritycontrol (zvichibva pachiteshi, kero yeMAC, kero yeIP, TCP port ID, kana UDP port ID), priority mapping uye modification zvichibva paToS field ne802.1p, uye DSCP differential services.

Inotsigira kudzora bandwidth (zvichienderana nechiteshi, kero yeMAC, kero yeIP, TCP port ID, kana

ID yechiteshi cheUDP) ine granularity yekudzora ye64 kbit/s.

Inotsigira nzira nhatu dzekuronga queue: priority queue (PQ), weighted round robin (WRR), uye PQ+WRR.

Inotsigira HQoS, iyo inovimbisa bandwidth yemasevhisi akawanda kune vashandisi vakawanda: Danho rekutanga rinovimbisa bandwidth yemushandisi, uye danho rechipiri rinovimbisa bandwidth yebasa rega rega remushandisi wega wega. Izvi zvinovimbisa kuti bandwidth yakavimbiswa inogoverwa zvakakwana uye bandwidth yakasununguka inogoverwa zvakaenzana.

Matanho akakwana ekuchengetedza

Nhevedzano yeMA5683T inosangana nezvinodiwa zvekuchengetedza zvemasevhisi ekutaurirana, inoshandisa zvizere maprotocol ekuchengetedza, uye inovimbisa zvizere kuchengetedzwa kwesystem nemushandisi.
