5G uye Network Slicing
Kana 5G ichitaurwa zvakanyanya, Network Slicing ndiyo yakanyanya kukurukurwa tekinoroji pakati pavo. Vashandi veNetwork vakaita seKT, SK Telecom, China Mobile, DT, KDDI, NTT, uye vatengesi vemidziyo vakaita saNokia, Nokia, uye Huawei vese vanotenda kuti Network Slicing ndiyo yakanakira network yekuvaka yenguva ye5G.
Iyi tekinoroji nyowani inobvumira vashandisi kupatsanura akawanda chaiwo ekupedzisira-kusvika-kumagumo network mune yehardware zvigadzirwa, uye imwe neimwe Network Slice inonzwisisika yakasarudzika kubva kune mudziyo, kuwana network, yekufambisa network uye musimboti network kusangana neakasiyana maitiro emhando dzakasiyana dzemasevhisi.
Kune yega yega Network Slice, zviwanikwa zvakatsaurirwa zvakaita sevhavhavhavha, network bandwidth, uye mhando yebasa zvinovimbiswa zvizere. Sezvo zvimedu zvakaparadzaniswa kubva kune mumwe nemumwe, zvikanganiso kana kukundikana mune imwe chidimbu hazvizokanganisa kutaurirana kwezvimwe zvimedu.
Sei 5G ichida Network Slicing?
Kubva kare kusvika kune yazvino 4G network, nharembozha dzinonyanya kushandira nharembozha, uye kazhinji inongoita imwe optimization yenharembozha. Nekudaro, munguva ye5G, nharembozha dzinoda kushandira michina yemhando dzakasiyana uye zvinodiwa. Mazhinji emamiriro ekushandisa akataurwa anosanganisira mobile Broadband, yakakura-chiyero iot, uye mishoni-yakakosha iot. Vese vanoda marudzi akasiyana emanetiweki uye vane zvinodiwa zvakasiyana mukufamba, accounting, chengetedzo, kutonga kwepolicy, latency, kuvimbika uye zvichingodaro.
Semuenzaniso, yakakura-yakawanda iot sevhisi inobatanidza yakagadziriswa sensors kuyera tembiricha, humidity, kunaya kwemvura, nezvimwewo. Hapana kudikanwa kwekupihwa, kugadziridzwa kwenzvimbo, uye mamwe maficha emafoni makuru ekusevha munharembozha. Pamusoro pezvo, mishoni-yakakosha iot masevhisi akadai sekutyaira akazvimirira uye kure kure kudzora kwemarobhoti kunoda kupera-kusvika-kumagumo latency yemamilliseconds akati wandei, ayo akasiyana zvakanyanya nenharembozha Broadband masevhisi.
Main Application Scenarios ye5G
Izvi zvinoreva here kuti tinoda network yakatsaurwa yesevhisi yega yega? Semuenzaniso, imwe inoshandisa nharembozha dze5G, imwe inoshandira 5G yakakura iot, uye imwe inoshandira 5G mission yakakosha iot. Hatidi kudaro, nekuti isu tinogona kushandisa network slicing kupatsanura akawanda ane musoro network kubva kune yakaparadzana yemuviri network, inova nzira inodhura kwazvo!
Zvido zvekushandisa zveNetwork Slicing
Iyo 5G network chidimbu inotsanangurwa mune 5G chena bepa rakaburitswa neNGMN inoratidzwa pazasi:
Isu tinoita sei kuguma-kusvika-kumagumo Network Slicing?
(1) 5G isina waya yekuwana network uye yakakosha network: NFV
Munharembozha yanhasi, mudziyo mukuru inharembozha. RAN (DU uye RU) uye mabasa epakati anovakwa kubva kune yakatsaurwa network michina inopihwa neRAN vatengesi. Kuita network slicing, Network Function Virtualization (NFV) chinhu chinodiwa. Chaizvoizvo, iyo pfungwa huru yeNFV ndeyekuisa network basa software (kureva MME, S/P-GW uye PCRF mupakati pepakiti uye DU muRAN) ese ari mumichina chaiyo pamasevha ekutengesa pachinzvimbo chekuparadzana mune yavo yakatsaurirwa. network zvishandiso. Nenzira iyi, iyo RAN inobatwa segore rekumucheto, nepo basa repakati rinobatwa segore repakati. Kubatana pakati peVMS iri kumucheto uye mukati mepakati gore kunogadziriswa uchishandisa SDN. Zvadaro, chimedu chinogadzirwa chesevhisi yega yega (kureva runhare mbozha, hombe iot slice, mission yakakosha iot slice, nezvimwewo).
Maitiro ekuita imwe yeNetwork Slicing (I)?
Iyo nhamba iri pazasi inoratidza kuti yega yega sevhisi-chaiyo application inogona kuvharidzirwa uye kuiswa muchikamu chega chega. Somuenzaniso, slicing inogona kugadzirwa sezvinotevera:
(1) UHD kucheka: virtualizing DU, 5G musimboti (UP) uye cache maseva ari mupendero gore, uye virtualizing 5G musimboti (CP) uye MVO maseva ari mukati megore.
(2) Kucheka kwefoni: virtualizing 5G cores (UP uye CP) uye maseva eIMS ane akazara ekufamba-famba mukati megore repakati.
(3) Yakakura-yakakura iot slicing (semuenzaniso, sensor network): Virtualizing iri nyore uye isina kuremerwa 5G musimboti mukati mepakati gore haina mafambiro ekufambisa masimba.
(4) Mission-yakakosha iot slicing: Virtualizing 5G cores (UP) uye maseva anosanganisirwa (semuenzaniso, V2X maseva) mumucheto wegore kuti uderedze kutapurirana latency.
Parizvino, isu tave kuda kugadzira zvimedu zvakatsaurirwa masevhisi ane zvakasiyana zvinodiwa. Uye iwo chaiwo network mabasa anoiswa munzvimbo dzakasiyana mune yega yega (kureva, mupendero gore kana musimboti gore) zvinoenderana neakasiyana masevhisi maitiro. Mukuwedzera, mamwe mabasa etiweki, akadai sekubhadhara, kutonga kwemitemo, nezvimwewo, zvingave zvakakosha mune zvimwe zvimedu, asi kwete mune zvimwe. Vashandi vanogona kugadzirisa network slicing nenzira yavanoda, uye pamwe ndiyo inonyanya kudhura nzira.
Maitiro ekuita imwe yeNetwork Slicing (I)?
(2) Network slicing pakati pemupendero uye musimboti gore: IP/MPLS-SDN
Software inotsanangurwa networking, kunyangwe iri nyore pfungwa payakatanga kuunzwa, iri kuramba ichinetsa. Kutora chimiro cheKuvharira semuenzaniso, SDN tekinoroji inogona kupa network yekubatanidza pakati pemashini chaiwo pane iripo network network.
Kupera-ku-kuguma Network Slicing
Chekutanga, isu tinotarisa maitiro ekuona kuti network yekubatanidza pakati pemupendero gore uye musimboti wegore virtual michina yakachengeteka. Iyo network pakati pemakina chaiwo inoda kuitwa zvichibva paIP/MPLS-SDN uye Transport SDN. Mupepa rino, tinotarisa IP/MPLS-SDN inopiwa nevatengesi ve router. Ericsson uye Juniper vese vanopa IP/MPLS SDN network yekuvaka zvigadzirwa. Mabasa acho akasiyana zvishoma, asi kubatana pakati peSDN-based VMS kwakafanana.
Mukati megore mune virtualized maseva. Mune hypervisor ye server, mhanya yakavakirwa-mukati vRouter/vSwitch. Iyo SDN controller inopa tunnel yekumisikidza pakati peiyo virtualized server uye DC G/W router (iyo PE router inogadzira iyo MPLS L3 VPN munzvimbo yegore data). Gadzira tunnels dzeSDN (kureva MPLS GRE kana VXLAN) pakati pemuchina wega wega (semuenzaniso 5G IoT musimboti) uye DC G/W marauta ari mukati megore.
Iyo SDN controller inobva yagadzirisa mepu pakati pematanho aya neMPLS L3 VPN, senge IoT VPN. Maitiro acho akafanana mumakore ekumucheto, achigadzira iot slice yakabatana kubva kumucheto gore kuenda kuIP/MPLS musana uye nzira yese kuenda kupakati gore. Iyi nzira inogona kuitwa zvichibva pamatekinoroji uye zviyero zvakakura uye zviripo kusvika parizvino.
(3) Network slicing pakati pemupendero uye musimboti gore: IP/MPLS-SDN
Chasara parizvino inharembozha fronthawall network. Isu tinocheka sei iyi mobile fronthold network pakati pemupendero gore ne5G RU? Chekutanga pane zvese, iyo 5G yekumberi-haul network inofanirwa kutanga yatsanangurwa. Pane dzimwe sarudzo dziri kukurukurwa (semuenzaniso, kuunza itsva pakiti-yakavakirwa kumberi network nekutsanangudza mashandiro eDU neRU), asi hapana tsananguro yakajairwa yaitwa. Iyi inotevera dhizaini inoratidzwa muITU IMT 2020 inoshanda boka uye inopa muenzaniso weiyo virtualized fronhaul network.
