Abstract

In an example, a network switch is configured to operate natively as a load balancer. The switch receives incoming traffic on a first interface communicatively coupled to a first network, and assigns the traffic to one of a plurality of traffic buckets. This may include looking up a destination IP of an incoming packet in a fast memory such as a ternary content-addressable memory (TCAM) to determine whether the packet is directed to a virtual IP (VIP) address that is to be load balanced. If so, part of the source destination IP address may be used as a search tag in the TCAM to assign the incoming packet to a traffic bucket or IP address of a service node.
