Use Case Proposal for the Wireless & Mobility Working Group Daniel Corujo, Carlos Guimarães, Rui Aguiar Charles Perkins Subir Das MISU OpenFlow_PoA

Outline Introduction Base Scenario Proposed System Plan MISU OpenFlow_PoA

Introduction IEEE targets the facilitation and optimization of handover scenarios  In multi-technology environments It provides technology-agnostic…  … Link layer events (i.e., link up, link down, link parameter changes  RSSI)  … Link layer commands (i.e., device link actions, network point of attachment query and commit) MISU OpenFlow_PoA

Introduction (cont’d) These are quite useful for  Detecting and acting regards the dynamics of wireless environments  Convey this information/actions in a remote way Different scenarios become enabled  Handover optimization  Monitoring  Load balancing  … MISU OpenFlow_PoA

Base Scenario Empower networking control/management/configuration mechanisms with the ability to  Perceive the Mobile Terminal’s perspective on its wireless link to the network, and leverage it to …  Determine an action to re-optimize/re-configure/re- control/re-manage that wireless link  And others involved/impacted MISU OpenFlow_PoA

Base Scenario (cont’d) Specific SDN impact of the scenario  The controller gets “fed” with link status information from wireless network entities  Either through query or triggered events –Thresholds can be pre-configured and events registered  The controller can re-organize SDN flows affected by wireless link conditions  Either wireless backhaul, or links terminating in wireless Points of Attachment  It also enables preemptive actions, through the preparation of links before the mobile nodes move there MISU OpenFlow_PoA

Examples – Load Balancing OpenFlow PoA #1 OpenFlow PoA #2 MN OpenFlow Switch OpenFlow Controller MN MISU OpenFlow_PoA

Examples – Handover Optimization PoA sends monitoring data to Controller (i.e., Load Values) OpenFlow PoA #1 OpenFlow PoA #2 OpenFlow Switch OpenFlow Controller MN MISU OpenFlow_PoA

Examples - Monitoring OpenFlow PoA #1 OpenFlow PoA #2 MN OpenFlow Switch OpenFlow Controller CN MN MISU OpenFlow_PoA

Proposed System Wireless Interfaces (at Network Equipment and mobile terminals)  Able to provide wireless link related information to an “OpenFlow Controller”  New counters, parameters… OpenFlow PoA #1 OpenFlow Switch OpenFlow Controller MN MN wireless interface information PoA wireless interface information Ctrl combines MN and PoA Wireless info w/ Ethernet Switch Info, for optimization MISU OpenFlow_PoA

Proposed System (cont’d) Controller is able to send commands to wireless entities  Controlling wireless link aspects operation Controller makes use of previously collected/received wireless information  Reconfigures both wired/wireless affected equipment OpenFlow PoA #1 OpenFlow Switch OpenFlow Controller MN MISU OpenFlow_PoA

Plan Dual evolution process  Some aspects discussed here can also motivate evolutions in IEEE  IEEE – Services and Use Cases  For example, PoA-based events Leverage from existing work, showcasing OpenFlow and Wireless integration scenarios  I.e., previous demo Next step: Assess architectural and protocol impact to OpenFlow  Identify parameters, structures and procedures MISU OpenFlow_PoA
