This white paper concentrates on the particular aspect of scalable network design using SLB and illustrates how the Catalyst 6000, with its accelerated SLB capabilities utilizing server cache technology, provides network managers with the ability to balance services across numerous servers at speeds of millions of packets per second. To explain how accelerated SLB works in the Catalyst 6000 family, this paper provides an overview of the Catalyst 6000 family and its architecture, and then discusses traditional DNS methods of load-balancing and its shortcomings.
