Presentation Transcript
OpenFlow-based load balancing for wireless mesh infrastructure Consumer Communications and Networking Conference (CCNC), 2014 IEEE 11th Dept. of Electr. & Comput. Eng., Clemson Univ., Clemson, SC, USA Author(s): Fan Yang, Gondi, V., Hallstrom, J.O., Kuang-Ching Wang, Eidson, G. 1
Outline Introduction Routing protocols in Wireless Mash Networks OpenFlow vs Traditional forwarding OpenFlow Technology Motivation System architecture Load Balancing Test Cases Experimental analysis Conclusion Reference 2
Routing protocols in Wireless Mash Networks Ad hoc On-Demand Distance Vector (AODV) Optimized Link State Routing Protocol (OLSR) link-state routing protocol Nodes advertise information only about links with neighbors. 3
Motivation Many routing protocols use pre-selected nodes for relaying traffic, causing those nodes to be heavily used, while leaving other nodes idle. It ensures that each node has approximately equal traffic to forward, so that optimal network performance is achieved throughout the network. 6
Load Balancing Test Cases Basic setup of data flow paths 8
Load Balancing Test Cases(Cont.) Data flow redirection between mesh nodes 9
Conclusion Traditional solutions require compute- intensive routing algorithms running at each mesh node. Presented combines OpenFlow Controller and a performance monitoring tool to enable real time data flow redirection. 11
