New load-balancing options using source or destination IP address only

New load-balancing options based solely on the source or destination IP address are available. Using only source IP or destination IP as the basis for generating load-balancing hashes helps service providers to ensure that both incoming and outgoing traffic through provider edge (PE) routers is sent toward the content server that maintains subscriber state for a given subscriber. These options are intended for use in deep packet inspection (DPI) networks with per-subscriber awareness and in environments that employ transparent caching.
