1

 Build network packet / traffic generator
(using ML310 board with Virtex-II Pro chip and Linux OS as a platform).
 Such generator can be used for various network testing purposes (connectivity, stress, etc.)
2

 Allow generation of different traffic patterns
 Including well-known attacks, such as Syn attack, Smurf attack, ping-of-death, etc.
 Allow customization and fine-tuning of the various packet generation parameters at different network stack layers (Ethernet frame, IP packet,
TCP/UDP packet)
3

 Learn Linux development in the embedded environment
 Gain deep knowledge of network protocols and network programming constrained by the limited resources of embedded system
4

 Build configurable, extensible and efficient system

 Implementing the main functionality in software allows us to build relatively complex system
 When using different Linux kernel services there’s no need to write everything from scratch
 Debugging is easier

Weeks 5-7
Weeks 8-10
Study the system, install and run Linux
Write prototype kernel module
Weeks 11-14,
Exams (break),
Finish after the exams
Implement “IP packet generator” object
Be able to send configurable IP packets with specified rate
Set up basic testing environment
(done concurrently with other stages)
