In one embodiment, a method for load balancing in a software-define networking (SDN) system includes, upon receiving a packet, determining whether a matching entry for the packet in a server distribution table contains both a current and new server selection. If the matching entry contains both, it is determined whether there is a matching entry for the packet in a transient flow table, where the transient flow table maintains server selections when at least one of the plurality of servers is reconfigured. Upon determining that there is no matching entry for the packet in the transient flow table, the method determines whether the packet is a first packet of a traffic flow. If the packet is the first packet of a traffic flow, the packet is forwarded according to the new server selection of the matching entry in the server distribution table, and the transient flow table is updated.

Exemplary methods for performing service chaining include generating a plurality of service chaining (SC) next hops (NHs) by, for each SC NH hop, generating a plurality of SC maps, each SC map identifying a chain of one or more service modules, wherein each service module is to apply a corresponding service on a packet. The methods further include generating a plurality of hosted NHs, each hosted NH including forwarding information that causes the packet to be forwarded to a corresponding service module. The methods further include in response to receiving a first packet, identifying a SC NH of the plurality of SC NHs based on an Internet Protocol (IP) address of the first packet, and forwarding the first packet to a service module based on the identified SC NH.

A method/system for removing redundancy in packets is disclosed. In one embodiment, for each of the sets of one or more consecutive bytes within the packet, the method divides the one or more consecutive bytes into a plurality of non-overlapping, consecutive segments; generates a segment feature for each of the plurality of non-overlapping, consecutive segments through application of a plurality of cryptographic hash functions with different random seeds; generates a single duplication feature based on a combination of the segment features for the plurality of non-overlapping, consecutive segments; and generates a single compressed string when a predetermined condition is met, based on a comparison of the single duplication feature and a set of stored duplication features. The method continues with sending the resulting strings in place of the packet toward the packet's destination.
