Future Internet: My Interests
• Ubiquitous
KC Wang, Clemson University Nov 18 2010 2
• Reliable • Performance• Secure• Information, context-centric • Customization
Future Internet = Computing + Connectivity + ClientsFuture Internet = Computing + Connectivity + Clients

ECE Wireless Labs –mobile and mesh networks, cognitive/software defined radio
GENI experimentation grants– Mobile gigabit wireless access (with
P. Ramanathan, UW-Madison)– Security and traffic analysis (with R.
Brooks)– Data sharing over heterogeneous
networks (with H. Shen)
GENI Programmable Wireless• GENI Cognitive Radio
– Clemson partners with Rutgers WINLAB on remote experimentation framework

Experiment DesignExperiment Design
• Hosts,storage• Network
• Entity: Application? Protocol? Middleware?• Goal: Get performance on real network
• Pick interesting scenario• Identify GENI resources
• Pick or design protocols (including those you normally don’t care!)
• In-network processing• Instrumentation (measurement tools)
• Real traffic• create DDoS
An Example
• Key features:– End hosts to emulate video server, video clients
– Legacy or OpenFlow switch in network backbone and edge network– Agent hosts next to network switches
– Mobile ad hoc network testbed

On-Campus Experiments• Four OpenFlow switches on campus recreate nationwide topology.• tc (netem) software to emulate different network characteristics (latency,
bandwidth, loss).• Measure at different points in network: iperf, tcpdump/wireshark, switch
statistics, ping, …
