| The OpenOnload User-level Network Stack |
 |
Google Tech Talks
February, 7 2008
ABSTRACT
The architecture of conventional networked systems
has remained largely
constant for many years now. However, some
specialised application domains
have adopted alternative architectures. For
example, the HPC community
uses message passing libraries which perform
network processing in
user-space in conjunction with the features of
user-accessible network
interfaces. Such user-level networking reduces
networking overheads
considerably without sacrificing the security and
resource management
functionality that the operating system normally
provides.
Supporting user-level TCP/UDP/IP networking for a
more general set of
applications poses considerable challenges,
including: intercepting system
calls, binary compatability with existing
applications, maintaining
security, supporting fork() and exec(), passing
sockets through Unix domain
sockets and advancing the protocol when the
application is not scheduled.
This talk presents the OpenOnload architecture for
user-level networking.
We describe our solutions to the challenges
outlined above, and novel
techniques to reduce CPU overhead, avoid lock
contention, minimise
interrupt overheads and improve cache efficiency.
Finally we present
performance results of the OpenOnload stack
including protocol compliance,
and plans for further work within the open source
community.

| Ravi Shankar - US Network Debut ? |
 |
The master of the sitar's 1968 appearance on the
Smothers Brothers show. Probably his first
network TV appearance in the US. Arguably the
greatest musician I've ever seen in my life. His
dexterity is astonishing.
