Uburyo bwo gukoresha OTN

OTN na PTN
Byagombye kuvugwa ko OTN na PTN ari ikoranabuhanga ritandukanye rwose, kandi mu buryo bwa tekiniki, byagombye kuvugwa ko nta sano ririho.
OTN ni umuyoboro w’ubwikorezi bw’amajwi, wakomotse ku ikoranabuhanga risanzwe ryo kugabanya ubunini bw’umuraba. Yongeraho ahanini imikorere y’ikoranabuhanga ryo guhinduranya amajwi mu buryo bw’ubwenge. Ishobora gukora crossover y’amajwi binyuze mu gushyiraho amakuru nta fibre jumpers zakozwe n’intoki. Uburyo bwo kubungabunga no koroshya imikoranire y’ibikoresho bya WDM birarushaho kunozwa cyane. Muri icyo gihe, umuyoboro mushya wa OTN ugenda uhinduka buhoro buhoro ugera ku muyoboro munini w’amajwi, uduce duto, no kurinda bikomeye.

PTN ni umuyoboro w’itumanaho utwara amapaki, ukaba ari umusaruro wo guhuza umuyoboro w’itumanaho n’umuyoboro w’amakuru. Porotokole nyamukuru ni TMPLS, ifite ibice bike bya IP n’amapaki menshi yo hejuru kurusha ibikoresho by’itumanaho. Ishobora gukora imiyoboro y’itumanaho n’uburinzi. Ni umuyoboro w’itumanaho ukoresha uburyo bwa carrier (imiyoboro isanzwe y’itumanaho ntishobora kuzuza ibisabwa n’urwego rw’itumanaho). Umuyoboro w’itumanaho wa PTN ni muto ugereranije n’uwa OTN. Muri rusange, umuyoboro ntarengwa wa PTN ni 10G, umuyoboro umwe wa OTN ni 10G, inzira y’itsinda ishobora kugera kuri 400G-1600G, kandi ikoranabuhanga rigezweho rishobora kugera kuri umuyoboro umwe wa 40G. Ni wo musingi w’umuyoboro w’itumanaho.

OTN na SDH, WDM

OTN ishingiye ku ikoranabuhanga rya WDM, ubushobozi bukomeye bwo gukora, kubungabunga, gucunga no gutanga serivisi (OAM) bwa SDH bukoreshwa hashingiwe ku bushobozi bunini cyane bwo kohereza amakuru. OTN ikoresha FEC isanzwe, ikungahaye ku nshingano zayo zo kubungabunga no gucunga amakuru, kandi ikwiriye serivisi nini zo gukosora amakosa ya FEC, ibyo bikaba binoza imikorere y’amakosa ya biti kandi byongera igihe cyo kohereza amakuru hakoreshejwe optique.

Uburyo bwo gukoresha OTN

Umuyoboro w’ikoranabuhanga ushingiye kuri OTN uzatanga igisubizo cyiza cyo kohereza serivisi za interineti nini. Umuyoboro w’ubwikorezi ugizwe ahanini n’umuyoboro w’ubwikorezi hagati y’intara, umuyoboro w’ubwikorezi hagati y’intara, n’umuyoboro w’ubwikorezi hagati y’intara. Umuyoboro w’ubwikorezi hagati y’intara ushobora kugabanywamo urwego rw’ibanze, urwego rw’ikusanyirizo n’urwego rw’ubugenzuzi. Ugereranyije na SDH, inyungu nini y’ikoranabuhanga rya OTN ni ugutanga gahunda n’uburyo bwo kohereza urwego rw’ubugenzuzi. Kubwibyo, niba ikoranabuhanga rya OTN rikoreshwa mu byiciro bitandukanye by’imiyoboro biterwa n’ingano y’urugero rw’urugero rw’umuyoboro w’ingenzi. Dukurikije uko umuyoboro umeze ubu, ibice by’ingenzi by’umurongo w’ibanze w’umuyoboro w’ubwikorezi hagati y’intara, umuyoboro w’ubwikorezi hagati y’intara n’umuyoboro w’ubwikorezi hagati y’intara muri rusange ni Gb/s no hejuru. Ikoranabuhanga ryiza rya OTN ryo kubaka.
Ku bijyanye no guteranya no kugera ku rwego rw'umuyoboro w'ubwikorezi mu gace k'umujyi (mu gace), iyo ibice by'ingenzi bigena gahunda bigeze ku rwego rwa Gb/s, ikoranabuhanga rya OTN naryo rishobora gukorwa neza.

1. Umuyoboro w’ubwikorezi bw’amatara mu gihugu hose Hamwe n’umuyoboro na serivisi bishingiye kuri IP, iterambere rya serivisi nshya n’ubwiyongere bwihuse bw’abakoresha interineti, urujya n’uruza rwa IP kuri trunk y’igihugu rwiyongereye cyane, kandi icyifuzo cy’umuyoboro w’amatara cyariyongereye cyane umwaka ku wundi. Umuyoboro w’amatara mu gihugu hose wa WDM utanga serivisi zo gukora intera ndende za PSTN/2G, serivisi zo gukora intera ndende za NGN/3G, na serivisi zo gukora intera ndende za interineti. Bitewe n’ubwinshi bwa serivisi zo gutwara, imiyoboro y’amatara mu gihugu hose ya WDM ikeneye byihutirwa kurinda serivisi zo gutwara. Nyuma yo gukoresha ikoranabuhanga rya OTN, uburyo bwo gutwara bwa IP y’umuyoboro w’igihugu hejuru ya OTN bushobora kurinda SNCP, kurinda umuyoboro w’impeta nk’iya SDH, kurinda umuyoboro wa MESH n’ubundi buryo bwo kurinda umuyoboro. Byagabanutse cyane.

2. Umuyoboro w’ubwikorezi bw’amatara mu ntara/mu karere. Routa z’imbere mu ntara/mu karere zitwara serivisi hagati y’ibiro bikorera kure (NGN/3G/IPTV/umurongo wihariye ku bakiriya bakomeye, nibindi). Binyuze mu kubaka umuyoboro w’ubwikorezi bw’amatara mu ntara/mu karere, serivisi zo kohereza amakuru mu buryo bwizewe kandi bwizewe za GE/10GE, serivisi za 2.5G/10GPOS nini zishobora kugerwaho; imiyoboro y’amatara, imiyoboro y’amatara igoye, n’imiyoboro ya MESH irashobora gushingwa; umuyoboro ushobora kwaguka uko ubikeneye; Kumenya gahunda n’uburyo bwo gutunganya serivisi z’uburebure bw’amatara/ubugari bw’amatara, no gutanga serivisi z’uburebure bw’amatara ku bakiriya banini; no kohereza izindi serivisi nka STM-1/4/16/64SDH, ATM, FE, DVB, HDTV, ANY, nibindi.

3. Umuyoboro w’ubwikorezi bw’amashanyarazi mu mujyi wa Metro/mu gace. Ku rwego rw’ibanze rw’umuyoboro wa metro, umuyoboro w’ubwikorezi bw’amashanyarazi mu mujyi wa OTN ushobora gutanga serivisi nini za interineti hagati ya router ya metro aggregation, router ya interineti yo mu gace C4 (akarere/akarere) na router ya metro core. Send. Interineti yo hejuru ya router ahanini ni GE/10GE, kandi ishobora no kuba 2.5G/10GPOS. Umuyoboro w’ubwikorezi bw’amashanyarazi mu mujyi wa Metro core l.
