What’s hindering IoT? Fragmentation Software, Services and Algorithms Multiplicity of standards Lack of open IP-Based Connectivity No cross-industrial standard / reference design Delay in IPv6 deployment Interoperability issues at different levels of Low Power “Self-healing sensor Network” software and hardware Efficient protocol and topology to form Heterogeneous Mesh Networks Creating flexible and scalable systems Security & Privacy Secure and authorized access IPv Privacy of User Data Models for decentralized authentication Data integrity at consumer devices Collective Intelligence Device & Data Management Seamless plug-n-play of sensor nodes Individual nodes and sensors may not be Managing millions of connected smart objects & “Smart” enough real time event handling Need to leverage big data and cluster of sensors/device to bring in collective intelligence Handling the huge data generated by IoT devices A.De 10
Software-Defined Networking (SDN) to IoT Separation of Control and Data Plane Heterogeneity in IoT Networks Network controlled by SW Applications; suitable Lack of open IP-Based Connectivity; delay in IPv6 backbone for mobile network deployment Uses general purpose hardware and commodity Efficient protocol and topology to form Heterogeneous servers Mesh Networks Enables automated, policy-based control of even Objects and protocols have specific design; forcing them to massive network fit with common and singular protocol not good option. Abstraction of Network Devices Not reference by individual devices IPv Plug-and-play set up of IoT devices Automatic remediation of security threats Software-defined things (SDT) Edge Computing and Analytics Server Virtualization and Connections Individual nodes and sensors potentially could generate tons of data Cloud network; one server acting as multiple servers Provisioning of edge computing/analytics turn Architecture for network OS with service/application data into insights oriented namespace Between server: east-west traffic 11
Summary: SDN Benefits to IoT Data Modeling and Parameters Connectivity, Robustness Real-time, Delay, Jitter, QoS Security, Reliability Dynamic Load Management: This enables operators to monitor and orchestrate automatic changes in bandwidth given overall network load. Ideal for global IoT providers readying for exponential increases in devices and data. Service Chaining: This enables operators to provision virtual security features like VPNs, firewalls and authentication and fix policy tolerances for performance in line with given subscriber’s entitlements. Also, distribution possible for NAT, DPI, Access control etc. Bandwidth Calendaring: This allows operators to schedule when and how much traffic a customer or application will need at specific time. Applicable to IoT services as many devices send data periodically only. 12
