The present invention provides for mapping of plurality of IP flows to a plurality service instances. A plurality of IP flows are received at a PDSN. The header information associated with each IP flow at the PDSN is parsed. Each IP flow is mapped to its corresponding service instance. The mapping criteria are defined by a flow filter. The flow filter can be generated within the PDSN, or outside of the PDSN such as by an MS. Each IP flow is transmitted on its corresponding service instance to its endpoint, such as an MS.
