5G: Hyped Expectations or Reality?With 5G and IoT, the use-cases and network requirements explode

• Programmatically defining the 5G virtualized network infrastructure to fit the behavior,
latency, bandwidth and security requirements of• Different IoT applications/verticals
• The ISP
• The Mobile Network Operator (MNO)
• The Mobile Virtual Network Operator (MVNO)
• The regional/global IoT service provider
5G and IoT: It’s all about the networkA platform for unconstrained provisioning and management or arbitrary networks

Monolithic networks cannot scale to support the
plethora of new 5G and IoT services.
Creation and management of isolated end-to-end
virtual networks with prescribed QoS SLAs.

The Need for Network Slicing

o The difference between VSNs and NSso VSN: A declarative definition of a service network
o NS: An imperative definition of a subset of a VSN
o Tools/languages for declarative definition of purpose-built networks
o Methods for clients to discover and attach to the appropriate slice
o Full automation in provisioning smart, dynamic virtual service networks

• Declarative instantiation of
VSNs & Slices (“one-click”)
• Hierarchical SDN control and
NFV integration
• Multi-cloud support
• Distributed Slice Selection
• QoS SLA enforcement through
dynamic resource management
and network optimization.
