Front and rear views of High Speed 

 Network (HNET) Testbed 



nese 64 Unix processors attaclied to 

 64 custom-chip switch nodes, each with 

 seven ports, serve as a high speed net- 

 worit. routing protocol testbed. The sys- 

 tem can be configured to be an 

 Asynchronous Transfer fvlode (ATlVl) 

 switch, for example, to allow expenmen- 

 tation with the efficiency of currently 

 evolving commercial offerings.
