Abstract: A switch/switching fabric is configured to load balance traffic. The switch fabric includes a plurality of switches. A packet is received at a first switch of the plurality of switches. The first switch load balances the packet to a particular entity among a plurality of entities. Each of the entities is connected to one of the plurality of switches. The first switch determines a particular switch of the plurality of switches to which the packet should be directed, the particular entity being connected to the particular switch of the plurality of switches. The particular switch receives the packet, and determines which interface of the particular switch to direct the packet to the particular entity. The plurality of entities include servers and network appliances as physical devices or virtual machines.
