趨勢說明 Cisco VNI Global Mobile Data Traffic Forecast, 2016–2021

https://communities.cisco.com/community/solutions/sp/vni-gci


By 2021, global mobile data traffic will reach an annual run rate of

587 exabytes per year, up from 87 exabytes in 2016

(7-fold growth).

122X More than mobile traffic generated in 2011

131 Trillion images (e.g., MMS or Instagram)

13 Trillion video clips (e.g., YouTube)

By 2021, a 5G connection will generate 30 GB/mo,

nearly 5X higher than the 6.3 GB/mo for

4G connections.

By 2021, M2M modules will be 29% of total global mobile devices and connections and will account for 5% (2.2 EBs/month) of mobile data traffic.


Extended Reality (XR) is a term referring to all real-and-virtual combined environments and human-machine interactions generated by computer technology and wearables. Examples: flying drones, underwater exploration.

Mixed Reality: Mixed reality (MR), sometimes referred to as hybrid reality, is the merging of real and virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time. Examples: entertainment industry.

Virtual Reality (VR) is an immersive multimedia or computer simulated environment which allows one to interact with it. Examples: complete immersive gaming, virtual aviation training, medical/surgical training, mental treatment.

Augmented Reality: Augmented reality (AR) is a view of a real-world environment whose elements are supplemented and enhanced by computer-generated sensory input such as sound, video, or graphics Examples: tourism, retail- furniture visualizers, clothes visualizer.

5G 主要的用例 5G Key Use Case & Enabling Technologies


From - Recommendation ITU-R M.2083

Enhanced Broadband (including fixed access) • Leverages mmwave “to the prem/device” for increased access

BW • Not concerned with connection density or latency. • May not need high mobility (e.g. for fixed access) • Data plane has to scale and deploy separately from

control plane and state management (CUPS)

IoT • Focused on low power wide area NB-IoT with high connection

density and energy efficiency • Slicing, flexible deployment, NFV Ultra-Reliable Low Latency • For mission critical use cases (self driving vehicles, ... Public

safety, ...) • Desired 1ms access time only refers to radio interface and

would be most useful in near field mission critical apps • Push data plane to the edge, remove state from user

plane

*https://www.itu.int/dms_pub/itu-t/oth/23/01/T23010000230001PDFE.pdf

Very high data rates Data plane has to scale orthogonally from control plane and state management

Very low latency Tactile and sheet of glass use cases need 1ms E2E latency* which implies MEC and IP at the edge

Mobile Edge Computing with CUPS

Mobile Control Plane

A very flat mobile core architecture based on CUPS • Internet access is via “Edge UP” • IMS and special APNs are accessed

via “centralized UP” • Edge UP+ CP is functionally equivalent

to StarOS and includes services (ADC, NAT, etc.)

Benefits • Offloaded traffic can be directed

to regional and metro caches for OTT video

• Offloaded traffic does not impinge on MSOs and is much simpler to network as it can be express directed to an Internet POC

5G CUPS Compared to LTE

RAN RAN

• 4G LTE requires all PDN connections for a given device to use the same SGW as a local anchor; whereas in CUPS, UP forwarding can be independently selected per PDN

• In 4G LTE, the control function is part of the network function whereas 5G decouples the control, functions consolidating them into a mobility control plane so that the user plane is fairly generic

• Policy, charging, and LI are all accessible via the common control plane in 5G CUPS and there is no need to go to each individual user plane function as in LTE

Cisco 5G-ready Network Architecture Recommendation

Packet switched infrastructure (Backhaul and Mid-haul has similar SLA/Transport requirement)

Fronthaul traditionally based on WDM - emergence of eCPRI and ROE (IEEE 1914.3) means packet based solution offering possible – Possible use of TSN (IEEE 802.CM)

Underlay evolving from IP/MPLS to MPLS/SR to SRv6 underlay with SDN techniques • Simplification and greater scale (if needed) addressed by SRv6 support

Greater b/w In the order of 4x (minimum) and potentially up to 8-10x over existing backhaul. • New platform position required - increased Ports and Performance with reduced cost per port – 50/100G required • Size and scale of backhaul and mid-haul determined on radio splits and RAN solution selected by operator.

Monitor Synchronization (Freq and Phase) requirements as will need to be supported in mid/backhaul in some deployment options.

• Support of PTP/SyncE mandatory with the option of 802.1CM (TSN).

Integration with Virtualisation stack/DC infra. is critical with “Network as a fabric” traction

E2E Security from application to network and access to core is key
