Netdev 0x16 - High Performance Programmable Parsers

Speakers: Tom A Herbert Info: Protocol parsing is perhaps the most common and performance sensitive operation in a networking stack. Every packet received on a network interface needs to be parsed for a variety of purposes, and hence there is a great deal of motivation to build parsers that are highly efficient and programmable to handle a wide variety of protocols. However, protocol parsing is notoriously difficult since it is inherently serialized processing, the number of protocol elements can be combinatorial, and the input to the parser is nondeterministic and sometimes even has malevolent intent (aka a Dos attack). In this paper we will delve into both the theory and implementation of programmable parsers that run with the highest performance in a given target environment. The implementation focus will be on software based parsers, however the techniques can be extrapolated for mapping to hardware implementation. See more: https://netdevconf.info/0x16/session....
