Cholumikizira cha mzere wa Huawei GPON OLT MA5683T Optical

Zinthu Zofunika Kwambiri

Kuphatikizana ndi kulumikizana

• Imapereka mphamvu yayikulu kwambiri yosinthira ma convergence. Makamaka, chipangizo cha MA5600T chimathandizira mphamvu ya backplane ya 1.5 Tbit/s, mphamvu yosinthira ya 960 Gbit/s, ndi ma adilesi a MAC 512,000.
• Imapereka mphamvu yotsika kwambiri yochotsera ma payipi. Makamaka, chipangizo cha MA5683T chimathandizira mautumiki okwana 24 x 10GE kapena 288 GE, popanda ma switch ena owonjezera.

Kudalirika kwambiri

• Imapereka mphamvu zodalirika kwambiri zolumikizirana ndipo imatsimikizira kuti pali njira ziwiri zosungiramo zinthu zotentha za OLT, kupirira masoka akutali, komanso kukweza mautumiki popanda kusokoneza.
• Imapereka ntchito zonse za Quality of Service (QoS) ndipo imathandizira kasamalidwe ka magulu a magalimoto, kuwongolera zinthu zofunika, ndi kuwongolera bandwidth. Ntchito ya Hierarchical-Quality of Service (H-QoS) imakwaniritsa zofunikira zosiyanasiyana za Pangano la Utumiki (SLA) la makasitomala amalonda.
• Imapereka kapangidwe kodalirika kwambiri kochokera kumapeto mpaka kumapeto (E2E), komwe kumathandiza kuzindikira njira zotumizira mauthenga (Bidirectional Forwarding Detection (BFD), Smart Link, ndi Link.
Chitetezo cha Aggregation Control Protocol (LACP) chobwerezabwereza ndi chitetezo cha mzere wa GPON mtundu wa B/mtundu wa C kumbali yakumtunda.

Kupeza mwayi wopezeka m'zochitika zambiri

• Imathandizira kupeza mautumiki angapo achinsinsi a E1, ndi Native Time-Division Multiplexing (TDM) kapena Circuit Emulation Services over Packet (CESoP)/Structure-Agnostic TDM over Packet (SAToP).
• Imathandizira ntchito ya Emulated Local Area Network (ELAN) ndi Virtual Local Area Network (VLAN)-based internal traffic exchange, zomwe zimakwaniritsa zofunikira za mabizinesi ndi ma network ammudzi.
• Imathandizira ogwiritsa ntchito intaneti ya Internet Protocol (IPTV) kuti asalumikizane ndi intaneti. Subrack imodzi imathandizira ogwiritsa ntchito ma multicast 8,000 ndi ma channel 4,000 a multicast.

Kusintha kosalala

• Imathandizira GPON, 10G Passive Optical Network (PON), ndi 40G PON papulatifomu, zomwe zimathandiza kuti zinthu zisinthe mosavuta komanso kuti anthu azitha kupeza bandwidth yambiri.
• Imathandizira ma IPv4/IPv6 dual stacks ndi IPv6 multicast, zomwe zimathandiza kusintha kosalala kuchokera ku IPv4 kupita ku IPv6.

Kusunga mphamvu

• Imagwiritsa ntchito ma chip apadera kuti isunge mphamvu. Makamaka, ma doko 16 pa bolodi la GPON amagwiritsa ntchito mphamvu zosakwana 73 W.
• Imathandizira kuzimitsa yokha kwa bolodi lopanda ntchito komanso kusintha liwiro la fan mwanzeru, zomwe zimachepetsa kugwiritsa ntchito mphamvu kwa bolodi lopanda ntchito.

Mphamvu yolumikizira ya GPON/EPON yolumikizidwa bwino

1. Kuthekera kopeza EPON 

Kapangidwe ka mfundo mpaka mfundo zambiri (P2MP) kamagwiritsidwa ntchito kuthandizira kuwala kosagwira ntchito

Kutumiza kudzera pa Ethernet. Mitengo yofanana ya 1.25 Gbit/s imathandizidwa kuti ipereke ntchito za broadband yothamanga kwambiri, zomwe zimakwaniritsa bandwidth

zofunikira za ogwiritsa ntchito mwayi wopeza.

Mu njira yotsikira, bandwidth imagawidwa ndi ogwiritsa ntchito osiyanasiyana mu encrypted

njira yofalitsira. Pa njira yopita kumtunda, nthawi yogawa ma multiplex (TDM) imagwiritsidwa ntchito kugawana bandwidth.

Mndandanda wa MA5683T umathandizira kugawa kwa bandwidth yosinthika (DBA) ndi kuchuluka kwa 64 kbit/s. Chifukwa chake, bandwidth ya ogwiritsa ntchito terminal ya ONT ikhoza kugawidwa mosinthika kutengera zomwe ogwiritsa ntchito akufuna.

Dongosolo la EPON limagwiritsa ntchito ukadaulo wotumizira mawayilesi opanda kuwala, ndipo chogawanitsa mawayilesi chogwiritsa ntchito mawonekedwe a P2MP ndikuthandizira chiŵerengero chogawanitsa cha 1:64.

Mtunda wothandizidwa ndi magiya otumizira ndi mpaka 20 km.

Ukadaulo wosinthira ukhoza kukhala wokonzekera kusinthasintha, wodziyimira pawokha, kapena woyambira kusinthasintha.

Kutha kupeza GPON

Mtengo wapamwamba umathandizidwa. Mtengo wotsika ndi 2.488 Gbit/s ndipo mtengo wapamwamba ndi 1.244 Gbit/s.

Mtunda wautali umathandizidwa. Mtunda wapamwamba kwambiri wotumizira mauthenga a ONT ndi 60 km. Mtunda weniweni pakati pa ONT yakutali kwambiri ndi ONT yapafupi ukhoza kukhala 20 km.

Chiŵerengero chachikulu cha kugawanika chimathandizidwa. Bolodi lolowera la GPON la madoko 8 limathandizira chiŵerengero cha kugawanika cha 1:128, chomwe chimawonjezera mphamvu ndikusunga zinthu za ulusi wa kuwala.

Kuchuluka kwa thupi kumathandizidwa. Mndandanda wa MA5683T umapereka mwayi wopeza ma GPON a ma 8-port kapena ma 4-port

bolodi kuti liwonjezere mphamvu ya dongosolo.

Ntchito ya H-QoS (ubwino wautumiki) imathandizidwa kuti ikwaniritse SLA

zofunikira za makasitomala osiyanasiyana amalonda.

Mphamvu ya QoS yamphamvu

Mndandanda wa MA5683T umapereka mayankho amphamvu a QoS otsatirawa kuti athandize

kasamalidwe ka mautumiki osiyanasiyana:

Imathandizira kulamulira zinthu zofunika (kutengera doko, adilesi ya MAC, adilesi ya IP, ID ya doko la TCP, kapena ID ya doko la UDP), mapu ndi kusintha zinthu zofunika kutengera gawo la ToS ndi 802.1p, ndi mautumiki osiyanasiyana a DSCP.

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

ID ya doko la UDP) yokhala ndi kuchuluka kwa 64 kbit/s.

Imathandizira njira zitatu zokonzekera mndandanda: mzere woyambira (PQ), robin wozungulira wolemera (WRR), ndi PQ+WRR.

Imathandizira HQoS, yomwe imatsimikizira bandwidth ya mautumiki ambiri kwa ogwiritsa ntchito angapo: Gawo loyamba limatsimikizira bandwidth ya ogwiritsa ntchito, ndipo gawo lachiwiri limatsimikizira bandwidth yautumiki uliwonse wa wogwiritsa ntchito aliyense. Izi zimatsimikizira kuti bandwidth yotsimikizika yagawidwa kotheratu ndipo bandwidth yophulika yagawidwa moyenera.

Njira zotsimikizira chitetezo mokwanira

Mndandanda wa MA5683T umakwaniritsa zofunikira za chitetezo cha mautumiki olumikizirana, umagwiritsa ntchito mokwanira njira zachitetezo, ndikuwonetsetsa mokwanira chitetezo cha makina ndi wogwiritsa ntchito.

1. Muyezo wa chitetezo cha dongosolo

Chitetezo ku kuukira kwa DoS (kukana utumiki)

kusefa adilesi ya MAC (media access control)

Kuukira kwa paketi ya Anti-ICMP/IP

Kusefa njira zoyendetsera ma adilesi a gwero

Mndandanda Woipa

2. Muyezo wa chitetezo cha ogwiritsa ntchito

Njira 82 ya DHCP (Dynamic Host Configuration Protocol) yowonjezerera chitetezo cha DHCP

Kulumikizana pakati pa ma adilesi a MAC/IP ndi madoko

Kusokoneza kwa Anti-MAC ndi kusokoneza kwa anti-IP

Kutsimikizira kutengera nambala ya seri (SN) ndi mawu achinsinsi a ONU/ONT

Kubisa katatu

Kutumiza kwa mauthenga obisika mu GPON komwe kuli pansi pa mtsinje kwa ogwiritsa ntchito osiyanasiyana,

monga AES (muyezo wotetezera wapamwamba) 128-bit encryption

GPON mtundu B OLT dual homing

Ulalo wanzeru ndi ulalo wowunikira wa netiweki yokhala ndi njira ziwiri zokwezera

Topology yosinthasintha ya netiweki

Monga nsanja yolumikizirana ndi mautumiki ambiri, mndandanda wa MA5683T umathandizira njira zingapo zolumikizirana ndi ma topology angapo a netiweki kuti akwaniritse zofunikira za topology ya netiweki ya ogwiritsa ntchito pazinthu zosiyanasiyana.

chilengedwe ndi ntchito.

Kapangidwe kodalirika ka gulu la chonyamulira

Kudalirika kwa dongosolo la mndandanda wa MA5683T kumaganiziridwa mu dongosolo,

mapangidwe a zida, ndi mapulogalamu kuti zitsimikizire kuti chipangizocho chikuyenda bwino.

Mndandanda wa MA5683T:

Amapereka ntchito zoteteza mphezi komanso zoletsa kusokonezedwa.

Imathandizira chenjezo la zolakwika pasadakhale pa zida zonse (zomwe zagwiritsidwa ntchito) ndi zida zina, monga fan,

magetsi, ndi batri.

Chitetezo cha 1+1 (mtundu B) cha doko la PON ndi kusintha kwa chitetezo cha 50 ms kwa ulusi wa optical wa msana kumathandizidwa.

Imathandizira kukweza komwe kukuchitika.

Imathandizira kuzindikira kutentha kwambiri kuti iwonetsetse kuti dongosololi ndi lotetezeka.

Ntchito zofufuza kutentha kwa bolodi, kukhazikitsa malire a kutentha, ndi kutseka kutentha kwambiri zimathandizidwa.

Imagwiritsa ntchito 1+1 redundancy backup ya bolodi lowongolera ndi bolodi loyang'anira la pamwamba.

Imathandizira kusinthana kwa hot pa ma board onse ogwirira ntchito ndi ma board owongolera.

Amapereka chitetezo cha soft-start, chitetezo cha current-limit, chitetezo cha current-limit, ndi chitetezo cha short circuit

mphamvu yolowera ya mabolodi omwe ali mu subrack kuti ateteze mabolodiwo ku kugunda kwa mphezi ndi kukwera kwa mafunde.

Imathandizira GPON mtundu B/mtundu C OLT dual homing.

Imathandizira ulalo wanzeru komanso ulalo wowunikira wa netiweki yokhala ndi njira ziwiri zokwezera.
