Abstract

Members of the Faculty of Information Technology, Brno University of Technology, take part in the Cesnet Research Plan, namely in 4 research activities - programmable hardware, distance education support, medical applications and virtual collaborative environment. We play a key role especially in the first domain which is described below.

Programmable hardware

The general aim of this activity is the development of specialised network devices based on the principle of hardware-software codesign. On the hardware side, we plan both to reuse the existing COMBO family of cards and also to create new designs utilising primarily high-performance programmable hardware components (FPGA, CPLD, TCAM etc.). Thanks to their flexibility, very different functions can be realised on the same hardware just by changing the appropriate microcode. A significant part of software development efforts will thus be spent on programming the microcode in the VHDL language, but we will also address the system and application software necessary for each particular device.

Besides design and development of the devices we use modern approches of modelling and verification to prove functionality of the systems. We use model checkers IF, TReX, Uppaal and others to simulate and verify certain properties of the system.

Our short-term goals are mostly related to our (ongoing or future) participation in EU projects. In 2004 we will continue the development of an IPv6 router (Liberouter) for the 6NET project, a traffic monitoring device for the SCAMPI project and start the development of a stand-alone NetFlow collector in the frame of the GN2 project. Also, we will finish a prototype of an optical repeater.

In a longer term, our goal is to build a sophisticated team consisting of researchers and students from several universities, CESNET and possibly other institutions. This team will cooperate closely with other CESNET research activities on the development of new devices, for example in the areas of optical technology, multimedia, security, large-scale computation etc.
