SUBJECT F6)

S. Keshav has announced the university release of a native-mode ATM protocol stack for x86 PCs running FreeBSD 2.0.5. The stack, described in a recent paper in Infocom 96 is based on work from the Indian Institute of Technology, Delhi. It provides:

• A reliable transport layer that does timeouts and retransmissions, with window flow control (developed from scratch)
• Leaky-bucket regulation at the transport layer
• A library that allows easy porting of socket/TCP applications to native-mode ATM
• SPANS signalling in user space. OS support automatically cleans up after applications that crash (see paper in Sigcomm '94).
• An example native-mode application: FTP
• High performance: 55 Mbps user-to-user with 486/66 PCs
• Operational since April '95; intensively tested
• Plug and play with Fore HPA-200 EISA cards and ASX series switches
• Four papers fully documenting the work are part of the distribution
• Source code for everything except the driver (driver source is available from Fore Systems).
