Zofunika Kwambiri

Kuphatikizika ndi mwayi wopezeka

• Amapereka wapamwamba lalikulu convergence kusintha mphamvu.Makamaka, chipangizo cha MA5600T chothandizira 1.5 Tbit/s backplane capacity, 960 Gbit/s switching capacity, ndi 512,000 maadiresi a MAC.
• Amapereka wapamwamba mkulu-kachulukidwe cascading mphamvu.Mwachindunji, chipangizo cha MA5683T chimathandizira ntchito zochulukirapo za 24 x 10GE kapena 288 GE, popanda ma switch owonjezera osinthira.

Kudalirika kwakukulu

• Amapereka maukonde odalirika kwambiri ndikuwonetsetsa zosunga zobwezeretsera zapawiri-OLT, kulolerana ndi masoka akutali, ndikukweza mautumiki popanda kusokonezedwa.
• Amapereka ntchito zonse za Quality of Service (QoS) ndikuthandizira kasamalidwe ka magulu a magalimoto, kuyang'anira patsogolo, ndi kuwongolera bandwidth.Ntchito ya Hierarchical-Quality of Service (H-QoS) imakwaniritsa zofunikira zosiyanasiyana za Service Level Agreement (SLA) za makasitomala amalonda.
• Amapereka mapangidwe odalirika kwambiri, omwe amathandiza Bidirectional Forwarding Detection (BFD), Smart Link, Link
Aggregation Control Protocol (LACP) redundancy chitetezo ndi GPON mtundu B/mtundu C chitetezo mzere kumtunda malangizo.

Multi-scenario access

•Imathandiza kupeza maulendo angapo a E1 achinsinsi, ndi Native Time-Division Multiplexing (TDM) kapena Circuit Emulation Services over Packet (CESoP)/ Structure-Agnostic TDM over Packet (SAToP) ntchito.
• Imathandizira ntchito ya Emulated Local Area Network (ELAN) ndi Virtual Local Area Network (VLAN) yotengera kusinthana kwa magalimoto mkati, kukhutiritsa mabizinesi ndi ma netiweki amtundu wamagulu.
• Imathandizira mwayi wosalumikizana ndi ogwiritsa ntchito ma TV a Internet Protocol (IPTV).Gulu limodzi laling'ono limathandizira ogwiritsa ntchito ma multicast 8,000 ndi ma tchanelo 4,000 a multicast.

Chisinthiko chosalala

• Imathandiza GPON, 10G Passive Optical Network (PON), ndi 40G PON pa nsanja, zomwe zimathandiza kuti zisinthidwe bwino komanso kukwaniritsa ultra-bandwidth access.
• Imathandizira ma IPv4/IPv6 ma stacks apawiri ndi IPv6 multicast, kupangitsa kusinthika kosalala kuchokera ku IPv4 kupita ku IPv6.

Kupulumutsa mphamvu

• Amagwiritsa ntchito tchipisi tapadera posunga mphamvu.Makamaka, madoko 16 pa bolodi la GPON amadya mphamvu zosakwana 73 W.
• Imathandizira kutulutsa mphamvu kwa board yopanda pake komanso kusintha kwanzeru kwa fan, ndikuchepetsa kugwiritsa ntchito magetsi osagwira ntchito.

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 MA5683T 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 MA5683T 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 MA5683T 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 MA5683T umakwaniritsa zofunikira zachitetezo cha ma telecommunication, gwiritsani ntchito ndondomeko zachitetezo, ndikuwonetsetsa chitetezo cha makina 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

Blacklist

2. Muyezo wachitetezo cha ogwiritsa ntchito

DHCP (Dynamic Host Configuration Protocol) Njira 82 kuti muwonjezere chitetezo cha DHCP

Kumanga pakati pa ma adilesi a MAC/IP ndi madoko

Anti-MAC spoofing ndi anti-IP spoofing

Kutsimikizika kutengera nambala ya serial (SN) ndi mawu achinsinsi a ONU/ONT

Katatu churning encryption

Kutumiza kwachinsinsi kumayendedwe a GPON kutsika kwa ogwiritsa ntchito osiyanasiyana,

monga AES (advanced encryption standard) 128-bit encryption

GPON mtundu B OLT wapawiri homing

Ulalo wa Smart ndikuwunika ulalo wa netiweki yokhala ndi njira ziwiri zakumtunda

Flexible network topology

Monga nsanja yopezera mautumiki ambiri, mndandanda wa MA5683T umathandizira njira zingapo zolumikizirana komanso ma topology angapo a netiweki kuti akwaniritse zofunikira za ogwiritsa ntchito pamanetiweki pazosiyana.

chilengedwe ndi ntchito.

Mapangidwe odalirika onyamula katundu

Kudalirika kwadongosolo kwa mndandanda wa MA5683T kumaganiziridwa mu dongosolo,

hardware, ndi mapangidwe a mapulogalamu kuti atsimikizire kuti chipangizocho chikuyenda bwino.The

Zithunzi za MA5683T

Amapereka ntchito zotsutsa mphezi komanso zotsutsana ndi kusokoneza.

Imathandizira chenjezo lolakwika pamagawo onse (ogwiritsidwa ntchito) ndi magawo, monga fani,

magetsi, ndi batri.

Chitetezo cha 1 + 1 (mtundu wa B) cha doko la PON ndi switchover ya 50 ms level service chitetezo cha backbone fiber fiber imathandizidwa.

Imathandizira kukweza mu-service.

Imathandizira kuzindikira kutentha kwakukulu kuti zitsimikizire chitetezo chadongosolo.

Ntchito zofunsa kutentha kwa bolodi, kukhazikitsa malire a kutentha, ndi kutentha kwakukulu kumathandizidwa.

Imatengera zosunga zobwezeretsera za 1 + 1 pa bolodi lowongolera ndi bolodi yolumikizira kumtunda.

Imathandizira kusinthana kotentha kwa matabwa onse ogwira ntchito ndi ma board owongolera.

Amapereka mayendedwe oyambira pang'onopang'ono, chitetezo chozungulira, chitetezo chocheperako, komanso chitetezo chachifupi

kwa mphamvu yolowera ya matabwa mu subrack kuteteza matabwa ku mphezi ndi mafunde.

Imathandizira GPON mtundu B / mtundu C OLT wapawiri homing.

Imathandizira ulalo wanzeru ndikuyang'anira ulalo wa netiweki yokhala ndi njira ziwiri zakumtunda.
