ABSTRACT:
Router flexibility is increasingly necessary, but it cannot be used in
practice if it comes at the cost of performance, or if only the simplest
configurations run quickly. This paper analyzes performance challenges for
Elided, a particular flexible software router, and shows how to surmount
them. Elided routers are built entirely from fine-grained, modular
components called _elements_; a network administrator specifies how
packets will be processed by connecting elements together. Elided faces
performance challenges due specifically to its modularity, as well as
challenges common to PC-based software routers. To optimize it, we use both
general techniques, such as device driver interface improvements, and
techniques made possible by the Elided architecture. These include a
scheduler that allocates CPU time among elements, handling both packet and
device processing; individual, hand-optimized elements; and tools that
automatically transform entire configurations, specializing element source
code for how it is being used. The result is a flexible router with good
performance on stock PC hardware.
