This is the port of the Click Modular Router. From the web page: Click is a new modular software router for PCs developed by MIT LCS's Parallel and Distributed Operating Systems group. Click routers are flexible, configurable, and easy to understand at a high level. They're also pretty fast (for software routers running on commodity hardware); on a 700 MHz Pentium III, a Click IP router can handle up to 435,000 64-byte packets a second. WWW: http://www.pdos.lcs.mit.edu/click/ This port of click runs only as a user mode process on FreeBSD. Kernel implementations run on Linux. There is a move afoot to port this code tot the FreeBSD kernel as well. See the mailing list (available via the web page) for more information. George V. Neville-Neil gnn@neville-neil.com
