What and where is VINCE?

Vince has now on record as the first "publicaly available" software
source code in the ATM technology area. This work was carried out by the
Research Networks section of the Center for Computational Science at the
Naval Research Laboratory, with support from the Advanced Research Projects
Agency and NAVSEA. In the Grand Internet Tradition, these fine folks have
contributed their efforts to the community in support of further research.

VINCE RELEASE 0.6 ALPHA

Vince, the Vendor Independent Network Control Entity, is
publicly available (in source code form) as an
alpha release. Its primary function is to perform ATM
signalling and VC management tasks. It currently includes
a hardware module that allows it to run on Fore ASX-100(tm)
switches. Other hardware modules are under development.

Vince consists of a core which provides basic ATM network
semantics, and modules to perform specific functions. Modules
included in this release are:

spans - module which intereroperates signalling and routing
with Fore Systems ASX switch and various host interfaces.
SPANS is (tm) Fore Systems, Inc.

q93b - an implementation of signalling as specified in the ATM
Forum UNI 3.0 document. The vince core includes sscop
and aal5 in its protocol library.

sim - a software ATM switch or host that can be used to test
signalling and routing implementations without ATM
hardware.

sroute - an address independent VC routing module.

The Vince distribution also contains a driver that uses spans for
signalling and supports the Fore Systems SBA-100 under SunOS(tm).

Work has already begun on a kernel version of Vince, which will
allow ATM Forum UNI signalling for hosts. Also in development
are SNMP/ILMI support, interdomain routing, and support for other
switches.

The intent is to provide a redistributable framework which
allows for code sharing among ATM protocol developers.

Vince and its architecture document are available for
anonymous ftp at hsdndev.harvard.edu:pub/mankin
