5G et network slicing
Cum 5G late, network slicing maxime de quibus technology in illis. Network Operators ut KT, Sk Telecom, Sina Mobile, DT, KDDI, NTT, et Equipment Vendolius ut Ericsson, Nokia est idealis network ad 5G era.
This new technology allows operators to split multiple virtual end-to-end networks in a hardware infrastructure, and each Network Slice is logically isolated from the device, access network, transport network and core network to meet the different characteristics of various types of services.
Nam network scalpere, dedicated opibus ut virtualem servientibus, network Sed et qualitatem servituti plene praestatur. Cum crustae sunt separenta ab invicem, errores vel defectis in unum scalpere non afficit communicationis alia crustae.
Quid est 5G opus network slicing?
Ex praeteritis ad current 4g network, mobile networks maxime serve mobile phones, et plerumque tantum facere aliquid optimization ad mobile phones. Sed in 5G era, mobile networks postulo ut servire cogitationes de variis generis et requisita. Multi de application missionibus de quibus includit mobile broadband, magna-scale iot, et missionem, discrimine. Et omne opus diversis rationes networks et diversis requisitis in mobilitate, ratio, securitatem, consilium imperium, latency, reliability et sic est.
Exempli gratia, magna-scale ioot ministerium coniungit fixum sensoriis ut metiretur temperatus, humiditas, pluvias, etc non est opus ad handovers, location updates et aliis features de principalis servientes phones in mobili network. Insuper, missio-discrimine iot servicia ut autonomae incessus et remotis imperium robots eget finis-ut-finem laency de pluribus milliseconds, quod est ipsum a mobili broadband officia.
Pelagus application missiones de 5g
Non hoc medium opus dedicated network pro se ministerium? Eg quis serves 5G mobile phones, qui servit 5G mole Iot, et unus serves 5G Missionis discrimine IT. Non opus est, quia non potest utor network slicing ad scindendum ex multa logica networks a separatum corporalis network, quod est valde cost-effective approach!
Applicationem requisitis ad network slicing
Et 5G network scalpere descripsit in 5G albus charta dimisit a NGMN ostenditur infra:
Ut faciam nobis efficiendum finem-ut-finem network slicing?
(I) 5G Wireless Access Network et Core Network: NFV
In hodie mobile network, pelagus fabrica est mobile phone. Cucurrit (du et Ru) et Core functiones sunt aedificata a dedicated network apparatu provisum est a cucurrit venditor. Ad effectum deducendi network slicing, network munus virtualization (NFV) est praerequisita. Basically, pelagus ideam de NFV est explicandi network munus software (ie mme, s / p-gw et pcrf in packet core et du in cucurrit) omnes in dedicated network in commercial servientibus pro separatim in dedicated network cogitationes. Et hoc modo, cucurrit, quod tractata est in ore nubes, dum core munus est tractata sicut core nubes. Nexum inter vms sita in ore gladii et in core nubes est configuratur per SDN. Deinde, a FRUSTUM est creatus pro se ministerium (id est Phone FRUSTUM, Massive IOT FRUSTUM, Missionis Critical IOT FRUSTUM, etc).
Quam ad effectum deducendi unum de network slicing (i)?
Formam infra ostendit quomodo se muneris-specifica applicationem potest esse virtualized et installed in se scalpere. Exempli gratia, slicing potest configurari ut sequitur:
(I) Uhd Slicing: Virtualizing Du, 5g Core (Sursum) et Cache Servers in ore gladii nubes et virtualizing 5g core (CP) et MVV
(II) Phone Slicing: Virtualizing 5g coros (et CP) et IMS servers cum plenum mobilitatem capabilities in core nubes
(III) magna-scale iooth slicing (eg, sensorem networks) Virtualizing a simplex et leve 5g core in core nubes non mobilitatem administratione elit
(IV) Missionis-discrimine IOT Slicing: Virtualizing 5G (Sursum) et consociata servientibus (eg, v2x servientibus) in extremis nubes ad minimizing tradenda latency
Ita longe, ut non opus ad creare dedicated crustae pro servicia cum diversis requisitis. Et virtualis network munera ponuntur in diversis locis in se scalpere (id est, ora nubes et core nubem) secundum diversas servitium characteres. Praeterea, quidam network functiones, ut exosculatio, consilium imperium, etc., potest esse necessarium in aliqua crustae, sed non in aliis. Operators potest customize network slicing via volunt, et verisimile maxime cost-efficens via.
Quam ad effectum deducendi unum de network slicing (i)?
(II) Network Slicing Inter Edge et Core Nubes: IP / MPLS, SDN
Software defined networking, quamvis simplex conceptu cum primum introducta est, fit magis magis complexu. Taking forma deaurabis ut exemplum, SDN technology potest providere network iunctio inter virtual machinis in existentium network infrastructure.
Finem-ad-finem network slicing
Uno modo, ut videamus quam ut in network iunctio inter ripam nubes et core nubes virtual machinis est secure. In network inter virtualem machinis postulo ut implemented secundum IP / MPLS, SDN et onerariam SDN. In hac charta, ut focus in IP / mplls, SDN provisum est per iter itineris. Ericsson et Juniperus et offer IP / mpls SDN Network Architecture Products. Operationes sunt leviter diversis, sed connectivity inter SDN, secundum VMS est simillima.
In core nubes sunt virtualized servientibus. In hypervisor de calculonis servi, currere in aedificata, in Vrouter / Vswitch. Et SDN Controller praebet cuniculum configuratione inter virtualized servo et DC G / W Router (in PE iter gignit MPLS L3 VPN in nube data Center). Partum SDN Tunnels (id MPLS GRE aut VXLAN) inter se virtualis apparatus (eg 5g IOT Core) et DC G / W speters in Core Nubes.
Et SDN moderatoris ergo manages in mapping inter haec cuniculis et MPLS L3 VPN, ut IOT VPN. Processus est in ore gladii nubes creando IOT FRUSTUM coniuncta a margine nubes in IP / MPLS backbone et usque ad core nubem. Hoc processus potest implemented secundum technologiae et signa quae sunt mature et available usque.
(III) Network Slicing Inter Edge et Core Nubes: IP / MPLS, SDN
Quid manet nunc est mobile fronthawall elit. Ut quid interficiam hoc mobile fronthold network inter ripam nubes et 5g ru? Primum omnium, 5G frontem, haut network esse defined primum. Sunt quidam options sub disputationem (eg, introducendis novum packet, secundum deinceps network per Redefining functionality of du et Ru), sed non vexillum definitio est adhuc. In his figure est diagram presented in ITU IMT MMXX operantes coetus et dat exemplum de virtui fronhaul network.
