An example method for load balancing in a network environment is provided and includes receiving a packet from a first stage load-balancer in a network environment, where the packet is forwarded from the first stage load-balancer to one of a plurality of second stage load-balancers in the network according to a hash based forwarding scheme, and routing the packet from the second stage load-balancer to one of a plurality of servers in the network according to a per-session routing scheme. The per-session routing scheme includes retrieving a session routing state from a distributed hash table in the network. In a specific embodiment, the hash based forwarding scheme includes equal cost multi path routing. The session routing state can include an association between a next hop for the packet and the packet's 5-tuple representing a session to which the packet belongs.
