New life for old routers

From Network World’s Tim Greene:

A team of computer scientists has proposed a new algorithm that makes routers operate more efficiently by automatically limiting the number of network route or link-state updates they receive.

The algorithm could be important in large heterogeneous corporate networks where the oldest, slowest routers make all the others wait while they absorb updates and recalculate their path tables. The Approximate Link State (XL) algorithm suppresses the updates so only those routers that are directly affected receive them, says Professor Stephan Savage, who along with three other computer scientists at the University of California at San Diego developed the algorithm. Savage presented a paper this week about XL at the Association for Computing Machinery’s conference of its Special Interest Group on Data Communications.
