    Use Cases & RINA Exploitation Opportunities

    2 May 22nd. 2018

    Market Perspective

     Potential 5G ‘Showstoppers’ Demand New Solutions/Stds

     Things 5G Needs that Only RINA Can Do…..especially for Network Slicing

     ‘Everything Moves …sometimes’ IoT Needs Mobility Mgt. within Slice

     Slices vary in Scope (RAN, MEC & Edge etc.) …New Approaches/Stds. Needed

     Killer App. for CSPs - Global vLANs for Enterprise – SD-WAN & VPN ‘On Demand’

     Multi-Carrier Network Problem ‘Bridging’ w/o Private Address Spaces

    Potential 5G ‘Showstoppers’ Demand New Solutions/Stds

    3

    Reference: Multi-billion dollar market opportunities may be lost unless Next Generation Broadband meets Seven Key Challenges

    Potential ‘Showstopper’ Potential Issues Possible 5G Solutions that Require Standards

    5G Access faster than Fixed

    Network

     Access no longer the Broadband Bottleneck - Fixed IP Network may be the ‘Choke Point’

     Multi-Access Edge Computing (MEC) w. Processing in 5G Infrastructure  Load Management at the Edge/PGW

    5G Small Cells, Multi-Frequency

    HetNets Interact Dynamically w.

    Devices/ Apps.

     Small cells require smooth fast ‘Soft Handover’ and dynamic SON based power control

     Smart User Applications can Request ‘Class of Service’

     Multi-Homing of Devices  Intelligent Channel Selection across Multi-frequency HetNet

    IoT Scale lacks Security Mechanisms  IoT entities exhaust Address Space  ‘Dumb’ IoT entities create Security problems

     Network Independent Personal or Unique Digital Identifiers (eSIM ‘like’)

    Security Threats demand Shift away

    from Assuming Trust to Positive

    Validation

     Massive DDoS Attacks on Network Infrastructure  Network Slices/Service Logic Chains and Hypervisor etc.

    Vulnerable e.g. to 'Phantom Attacks’  Large Scale Fraudulent User Service Access

     Separation of ‘IDs’ or Names from Network Addresses ‘No user App. should ever see a Network Address’

     Inherent Security w. Service Layer Isolation that Isolates Network from Users and Users from one another

     Authentication to Service Layer based on combined User/App./Device/ID.

    ‘Nailed Up’ 5G Net-work Slices

    Impede NFV Resource Allocation

     Network Slices conflict with NFV resource allocation - only guarantee QoS if ‘nailed up’ w. Tunnels and VPNs

     True Service Layers: End-to-End or with Variable Network Scope - Not 'Stacked Silos'. All resources/PNFs available to all VNFs

    Gigabit Traffic Bursts can Collapse

    TCP based networks

     Lack of Flow Control - Bursty Video and P2P Live Streaming could Crash Network

     Pro-Active Congestion Avoidance/Policy Based Load Management

    Data Centers do not Scale Globally

    w. Telco Cloud

     Network Scales but Data Center Islands hit limit - e.g. Exceed VXLAN I Million address limit

     Global Multi-Protocol Layer 2 Interworking for Software Defined Data Centers (SDDCs)

    Things Only RINA Can Do…5G Needs them all..

     Protocol Independent Layer 1 and Layer 2 Access & Services

     Global Layer 2 support for vLANs

     True End to End (E2E) Layer Management with Low Overhead

     Guarantee QoS/SLAs for ‘Network Slicing’

     Flow Control & Bursty Traffic Optimization

     Inherent Mobility: “Names are not Addresses” Personal or Unique Digital Identifiers are Network Independent

     Inherent Security: Isolation and Positive Authentication

     Inherent Order of Magnitude Improvement in Efficiency e.g. for 3GPP 5G Phase 2 ‘Service Based Architecture’ (SBA) Management/Control Transactions

    New Approaches and Standards Needed

    May 22, 2018 Copyright© 2018 Strategy Analytics, Inc.. 7

    What needs to be done in next 2 years to:

     Characterize Inbound Apps in Real Time and Dynamically Assign Apps to Slices

     Test Network Slicing under LTE with Flow Management over Shared Virtual Resources

     Ensure SLA guarantees are met efficiently

    New approaches, ecosystem collaboration and standards are needed to fully enable:

     Real Time Profile & Event based Application/Service Flow Allocation/Reallocation to New Slice(s)

     Enable Slices to share all Physical Resources in the Network

     Develop Business cases by Class/Quality of Service that generate 5G Revenues

    ngena – Global vLANs for Enterprise – SD-WAN & VPN solutions

    “ngena solutions allow enterprises to benefit from consistent data connectivity services around the globe.….. ngena provides a central cloud platform that merges the local networks of all alliance partners, forming a single global Software Defined Wide Area Network (SD-WAN). All ngena partners can deliver performant IP-VPN services to their end customers on a global scale. With this, enterprise customers get a global network service which is secure, stable, scalable and easy to use; and they profit from the local access and local care of their regional telecommunication provider.”

    “…..building a global backbone network connected via 20 data centers run by Equinix, which provide the jump-off point into the networks owned and run by their carrier partners via either Layer 2 Ethernet switches or Internet gateways. The clever part of its solution lies with the OpenStack-based software that Ngena runs on

    Cisco hardware in the data centers and in every customer network…. This code acts as a fully virtualized, software-based "service platform" that rides over the top of the Ethernet/IP transport network. All the apps, services and network orchestration are based in software, and delivered as VNFs (virtual network functions), allowing Ngena to manage the network end to end, all the way into the customer prem.”
