Abstract
The Virtual Interface Architecture (VIA) is an industry standard user-level communication architecture for
system area networks. The VIA provides a protected, directly-accessible interface to a network hardware,
removing the operating system from the critical communication path. In this paper, we design and
implement a user-level Sockets layer over VIA, named SOVIA (Sockets Over VIA). Our objective is to
use the SOVIA layer to accelerate the existing Sockets-based applications with a reasonable effort and to
provide a portable and high-performance communication library based on VIA to application developers.
SOVIA realizes comparable performance to native VIA, showing a minimum one-way latency of 10.5 μs
and a peak bandwidth of 814 Mbps on Giganet’s cLAN. We have shown the functional compatibility
with the existing Sockets API by porting File Transfer Protocol (FTP) and Remote Procedure Call (RPC)
applications over the SOVIA layer. Compared to the Giganet’s LAN Emulation (LANE) driver which
emulates TCP/IP inside the kernel, SOVIA easily doubles the file transfer bandwidth in FTP and reduces
the latency of calling an empty remote procedure by 77% in RPC applications.
