Kucheka kwe5G neNetwork
Kana 5G ichitaurwa zvakanyanya, Network Slicing ndiyo tekinoroji inonyanya kutaurwa nezvayo. Vashandi venetwork vakaita saKT, SK Telecom, China Mobile, DT, KDDI, NTT, pamwe nevatengesi vemidziyo vakaita saEricsson, Nokia, neHuawei vese vanotenda kuti Network Slicing ndiyo network architecture yakakodzera yenguva ye5G.
Iyi tekinoroji itsva inobvumira vashandisi kupatsanura ma network akawanda e-virtual kubva kumagumo kuenda kumagumo muzvivakwa zvehardware, uye Network Slice yega yega inoparadzaniswa nemudziyo, network yekupinda, network yekufambisa uye network huru kuti isangane nehunhu hwakasiyana hwemhando dzakasiyana dzemasevhisi.
PaNetwork Slice yega yega, zvinhu zvakatsaurirwa zvakaita semavirtual servers, network bandwidth, uye mhando yebasa zvinovimbiswa zvizere. Sezvo zvidimbu zvakaparadzana, zvikanganiso kana kukundikana kwechidimbu chimwe hazvizokanganisi kutaurirana kwezvimwe zvidimbu.
Sei 5G ichida Network Slicing?
Kubva kare kusvika pari zvino pari zvino pari zvino pari zvino pave ne4G network, ma network enharembozha anonyanya kushandira nharembozha, uye kazhinji anongogadzirisa nharembozha chete. Zvisinei, munguva ye5G, ma network enharembozha anofanirwa kushandira midziyo yemhando dzakasiyana siyana uye zvinodiwa. Zvizhinji zvezviitiko zvekushandisa zvinosanganisira mobile broadband, large-scale iot, uye mission-critical iot. Ose anoda marudzi akasiyana enetwork uye ane zvinodiwa zvakasiyana mukufamba, accounting, security, policy control, latency, reliability nezvimwewo.
Semuenzaniso, sevhisi yakakura ye iot inobatanidza masensa akagadziriswa kuti aone tembiricha, hunyoro, mvura inonaya, nezvimwewo. Hapana chikonzero chekupa vanhu, kugadzirisa nzvimbo, nezvimwe zvinhu zvemafoni makuru ari munharembozha. Pamusoro pezvo, masevhisi e iot akakosha sekutyaira kwega uye kudzora marobhoti ari kure anoda nguva yekunonoka kubva pakupera kusvika pakupera kwemamirisekonzi akati wandei, izvo zvakasiyana zvikuru nesevhisi dze mobile broadband.
Maitiro Makuru Ekushandisa e5G
Izvi zvinoreva here kuti tinoda network yakatsaurirwa kune yega yega sevhisi? Semuenzaniso, imwe inoshandisa nharembozha dze5G, imwe inoshandisa 5G massive iot, uye imwe inoshandisa 5G mission critical iot. Hatifanirwe kudaro, nekuti tinogona kushandisa network slicing kupatsanura network dzakawanda dzinonzwisisika kubva kune imwe network chaiyo, inova nzira inoshanda zvikuru!
Zvinodiwa zveKushandisa paNetwork Slicing
Chikamu che network ye5G chinotsanangurwa mupepa jena re5G rakaburitswa neNGMN chinoratidzwa pazasi:
Tinoita sei kuti Network Slicing ishande kubva pakutanga kusvika pakupedzisira?
(1) Network ye5G isina waya uye network huru: NFV
Mune network yemazuva ano yenharembozha, chishandiso chikuru inharembozha. RAN(DU naRU) uye mabasa epakati anovakwa kubva pamidziyo yenetwork yakatsaurirwa inopihwa nevatengesi veRAN. Kuti pave ne network slicing, Network Function Virtualization (NFV) chinhu chinodiwa. Pfungwa huru yeNFV ndeyekuisa software ye network function (kureva MME, S/P-GW uye PCRF mupacket core uye DU muRAN) zvese mu virtual machines pa commercial servers pane kuti ive yoga mumidziyo yavo yenetwork yakatsaurirwa. Nenzira iyi, RAN inobatwa se edge cloud, nepo core function ichibatwa se core cloud. Kubatana pakati peVMS iri pamucheto uye mu core cloud kunogadziriswa uchishandisa SDN. Zvadaro, slice inogadzirwa yebasa rega rega (kureva phone slice, massive iot slice, mission critical iot slice, nezvimwewo).
Maitiro ekushandisa imwe yeNetwork Slicing (I)?
Mufananidzo uri pazasi unoratidza kuti application yega yega yebasa inogona sei kuiswa pakombiyuta uye kuiswa muchikamu chimwe nechimwe. Semuenzaniso, kucheka kunogona kugadziriswa seinotevera:
(1) Kucheka UHD: kuita kuti DU, 5G core (UP) uye cache servers zvivepo mu edge cloud, uye kuita kuti 5G core (CP) neMVO servers zvivepo mu core cloud zvivepo.
(2) Kucheka nharembozha: kushandisa 5G cores (UP neCP) neIMS servers zviri nyore uye zvine simba rekufamba-famba mu core cloud.
(3) Kucheka ma iot akawanda (semuenzaniso, masensa network): Kuisa 5G core iri nyore uye yakareruka mu core cloud haina hunyanzvi hwekutonga kufamba.
(4) Kucheka iot zvine chinangwa chikuru: Kuisa macores e5G (UP) nemasevha akabatana nawo (semuenzaniso, maseva eV2X) mu edge cloud kuderedza nguva yekutumira data.
Kusvika pari zvino, tave tichida kugadzira zvidimbu zvakatsaurirwa zvemasevhisi ane zvinodiwa zvakasiyana. Uye mabasa enetwork ari munzvimbo dzakasiyana muchikamu chimwe nechimwe (kureva, edge cloud kana core cloud) zvichienderana nehunhu hwesevhisi hwakasiyana. Pamusoro pezvo, mamwe mabasa enetwork, akadai sekubhadharisa, kudzora mutemo, nezvimwewo, anogona kudiwa mune mamwe zvidimbu, asi kwete mune mamwe. Vashandisi vanogona kugadzirisa network slicing nenzira yavanoda, uye pamwe ndiyo nzira inodhura zvakanyanya.

(2) Kucheka network pakati pemupendero negore repakati: IP/MPLS-SDN
Kubatana kwesoftware, kunyangwe kuri pfungwa iri nyore payakatangwa kekutanga, kuri kuramba kuchiwedzera kuoma. Tichitora chimiro cheOverlay semuenzaniso, tekinoroji yeSDN inogona kupa network yekubatana pakati pema virtual machines pane network infrastructure iripo.
Kucheka Network kubva kumagumo kusvika kumagumo
Kutanga, tinoongorora kuti tingava sei nechokwadi chekuti kubatana kwenetiweki pakati peedge cloud necore cloud virtual machines kwakachengeteka. Network iri pakati pevirtual machines inofanirwa kushandiswa zvichibva paIP/MPLS-SDN neTransport SDN. Mupepa rino, tinotarisa paIP/MPLS-SDN inopihwa nevatengesi verouter. Ericsson neJuniper vese vanopa zvigadzirwa zveIP/MPLS SDN network architecture. Mashandiro acho akasiyana zvishoma, asi kubatana kuri pakati peSDN-based VMS kwakafanana zvikuru.
Mugore guru mune maserver akajairwa. Mu hypervisor yeseva, mhanyisa vRouter/vSwitch yakavakirwa mukati. SDN controller inopa magadzirirwo etunnel pakati peserver yakajairwa neDC G/W router (PE router inogadzira MPLS L3 VPN mu cloud data center). Gadzira SDN tunnels (kureva MPLS GRE kana VXLAN) pakati pemuchina wega wega (semuenzaniso 5G IoT core) uye DC G/W routers mu core cloud.
Mutongi weSDN anozogadzirisa mapping pakati pematunnel aya neMPLS L3 VPN, senge IoT VPN. Maitiro acho akafanana mu edge cloud, achigadzira iot slice yakabatana kubva ku edge cloud kuenda ku IP/MPLS backbone uye kusvika ku core cloud. Maitiro aya anogona kuitwa zvichibva pa tekinoroji nemazinga akura uye aripo kusvika pari zvino.
(3) Kucheka network pakati pemupendero negore repakati: IP/MPLS-SDN
Chinosara ikozvino inetwork ye mobile fronthawall. Tingacheka sei network iyi ye mobile fronthold pakati pe edge cloud ne 5G RU? Chekutanga, network ye 5G front-haul inofanira kutanga yatsanangurwa. Pane dzimwe sarudzo dziri kukurukurwa (semuenzaniso, kuunza network itsva ye packet-based forward nekushandura patsva mashandiro e DU ne RU), asi hapana tsananguro yakajairika yakaitwa parizvino. Mufananidzo unotevera idhayagiramu inoratidzwa muboka rekushanda re ITU IMT 2020 uye inopa muenzaniso we network ye virtualized fronhaul.
