Dr. Dobb's Journal August 1998: Fast IP Routing with LC-Tries

Fast IP Routing with LC-Tries

By Stefan Nilsson and Gunnar Karlsson

Dr. Dobb's Journal August 1998 

node = T[0];
pos = node.skip;
branch = node.branch;
adr = node.adr;
while (branch != 0) {
   node = T[adr + EXTRACT(pos, branch, s)];
   pos = pos + branch + node.skip;
   branch = node.branch;
   adr = node.adr;
}
return adr;

Example 1: Pseudocode for finding the string s in the LC-trie T.

    Modernize your Development by Moving Build and Code Quality Upstream
    Moderated by Jon Erickson, Editor-in-Chief of Dr. Dobb's, this interactive panel discussion brings industry experts Anders Wallgren, CTO of Electric Cloud and Gwyn Fisher, CTO of Klocwork together for a candid discussion of the cost savings, productivity and quality benefits that can be achieved by stabilizing builds and code quality as early in the development cycle as possible.

    The reality of today's development environment - geographically distributed teams, the use of Agile development practices, increasing application complexity, etc. - is straining the viability of the traditional coding, build and release process. To stay ahead of the curve, development teams are modernizing their approach to dealing with these issues, and as a result are achieving new levels of development productivity.
