Abstract:
A method is provided in one example embodiment and may include receiving a first Internet protocol (IP) flow for an IP session for a subscriber; selecting a first service function group from a plurality of service function groups to perform one or more services for the IP session for the subscriber, wherein each of the plurality of service function groups comprises a plurality of service function chain types and wherein each service function chain type comprises an ordered combination of one or more service functions; assigning the IP session for the subscriber to the first service function group; and forwarding the first IP flow for the IP session of the subscriber across a first service function chain type for the first service function group based, at least in part, on a service policy for the subscriber.
Abstract:
An example method includes reporting location changes for one or more users from a first network element to a second network element based on transitions for each of the one or more users in relation to a policy location area, wherein the policy location area is defined by one or more first user location information (ULI) information elements (IEs); communicating a per-peer Rx authorization and accounting request (Rx AAR) message to initiate a policy change, wherein the per-peer Rx AAR message comprises the one or more first ULI IEs; communicating a per-Diameter-peer Gx reauthorization request (Gx RAR) message including the one or more first ULI IEs; identifying one or more users for the policy change based, at least in part, on a corresponding ULI IE for each user and the one or more first ULI IEs; and applying the policy change to each of the identified one or more users.

Abstract:
In one embodiment, a method includes receiving one or more packets of a communication session from one or more interfaces, such that the interface is a subscriber interface or a network interface. The method further includes associating the communication session to an end user with a source Internet Protocol (IP) address of the packet if the packet is received from the subscriber interface or to an end user with a destination IP address of the packet if the packet is received from the network interface.
