Claim Text:
1. A method for providing redundancy in a service insertion architecture, comprising: providing a service classifier (SCL) that performs traffic classification and service header insertion, the service header including service ordering information related to one or more service nodes that apply service-specific policies to packets received at the SCL; providing a first services virtualization endpoint (SVE) and a second services virtualization endpoint (SVE), the first SVE and the second SVE each sharing a same virtual IP address in a control path, the first SVE and the second SVE each connected to the one or more service nodes in a data path; providing identical service chaining information in the first SVE and the second SVE, the identical service chaining information being indicative of a next hop associated with a service path; redirecting the packets received at the SCL to the virtual IP address such that both the first SVE and the second SVE are configured to forward the packets across the data path when the first SVE is active and then to the one or more service nodes, in accordance with a mapping for processing, the mapping being an ordered list of the one or more service nodes and a path connecting the one or more service nodes; and returning the packets to the SCL.
