  3. 3. 3 | AMD EMBEDDED SYSTEMS | MARCH 2015 | IoT NETWORK WITHOUT GATEWAYS OR “LIGHT GATEWAYS” CloudMobile / Wireline Access Network Data CenterThings Control Devices Cellular Network WAN Network IOT PAN/LAN Network
  4. 4. 4 | AMD EMBEDDED SYSTEMS | MARCH 2015 | ISSUES WITH NON-GATEWAY NETWORK / CLOUD CENTRIC APPROACH Network issues ‒ Cellular Network Limitations : Range, Bandwidth, Reliability in Buildings, power, penetration ‒ Cost of Spectrum ‒ Capacity ‒ Cost No Gateway / “Light” non-processing Gateway ‒ No redundancy if the Network Connection/Cloud App. is lost ‒ No local processing : this will impact processing time ‒ It will be difficult to implement uniform security policies.
  5. 5. 5 | AMD EMBEDDED SYSTEMS | MARCH 2015 | ENTERPRISE SOLUTION FOR IOT WITH GATEWAYS Security + Access Control Business Premise IOT Network Cloud Data Center HVAC + Power + Lighting Irrigation and Water Mgmt. Control Devices IOT Access Gateway Solar Energy Management IOT Gateway • Local Intelligence : provides redundancy during network/cloud outages • Faster local processing • Future proofed for enhanced Applications Support • Mitigates access bottlenecks • Uniform security policies can implemented Cellular Network WAN Network Mobile / Wireline Access Network
  6. 6. 6 | AMD EMBEDDED SYSTEMS | MARCH 2015 | IoT GATEWAY CHALLENGES IOT Access Gateway Multi-protocol Connectivity Support all the protocols used to connect sensors, actuators, control devices and network uplinks High Performance Processing For certain specialized workloads such as Machine Vision and Biometric processing for fast response time Manageability Support SDN enabled Networking stacks for configuration, management, automation, orchestration. Cost effective solution Gateway is cost optimized for lower BOM cost. Lower power, fan less operation. CPU throughput / redundancy CPU throughput to support standalone operation in case of loss of connection to the cloud Scalability Platform HW and SW architecture must be built for addition of future applications and related devices OS Platform OS platform should have wide acceptability and must support a diverse device and applications ecosystem Device Ecosystem Gateway platform should support rich ecosystem of present and future devices : sensors, actuators, control devices Local Processing vs Cloud The Gateway Architecture should partition this very carefully the main tradeoff is between faster response time vs cloud/big data capabilities
