This demo will provide three modes to show the CAPWAP offloading capability of QorIQ platform. mode Iis the core-through mode which can be implemented by the CAPWAP stack to send the CAPWAP stack packets; Mode II is the offloading-mode which demonstrates the CAPWAP Encapsulation/De-capsulation capability of the SoC, and can be used in the AC case; Mode III is the net-bridge mode which is the basic usage for EAP which bridge the packets from PCIE to SEC and FM for offloading CAPWAP manipulation, the bridge is zero-memory copy in order to get high performance data. Together with the throughput data, this demo will help the customer to evaluate the EAP design with QorIQ platform.




  • QorIQ T1 processors handle secure WLAN tunnels with offload engines instead of CPU cycles
  • CAPWAP tunneling firmware performs extra tasks (frag/ reassembly) and interfaces to the Linux user
  • Highly efficient bridging to WLAN radios ensures maximum WLAN performance
  • CAPWAP fragmentation and reassembly
