  As broadband access to high speed research and education networks has become
increasingly available to radio telescopes around the world the use of e-VLBI
has also increased. High bandwidth e-VLBI experiments have been achieved across
wide areas (Whitney et al., 2003). e-VLBI has also been used for the transfer
of data from "production" experiments. As the use of e-VLBI becomes more and
more prevalent, the need to have some form of standard framework for
facilitating interoperability between various acquisition, transport and
processing systems around the world is becoming increasingly important. This is
the motivation behind the VLBI Standard Interface - Electronic (VSI-E)
standard. VSI-E is currently in draft form [\cite{bib-vsie}] and is going
through the standards process within the VLBI community. In this poster, we
describe an initial reference implementation of the VSI-E protocol. The
implementation has been done using the C/C++ language and is in the form of a
re-useable library. It has been developed on the Linux platform and can be
easily ported to most POSIX-compliant platforms. The reference implementation
also includes a high-performance application level transport protocol. That can
be used to transport data within the framework of VSI-E.
