System and method for transporting information to services in a network environment
First Claim
1. A method, comprising:
- receiving an update for a service at a local policy anchor included in a gateway, wherein the service is included in one or more service chains accessible by the gateway and wherein the update is at least one of a policy update and a charging update;
determining if the local policy anchor has a session established with the service;
communicating the update to a classifier within the gateway if the local policy anchor does not have a session established with the service;
determining, by the classifier, one or more service chains including the service if the local policy anchor does not have a session established with the service;
injecting, by the classifier, a packet including a service header containing the update into the one or more determined service chains including the service if the local policy anchor does not have a session established with the service; and
communicating the update to the service from the local policy anchor if the local policy anchor has a session established with the service.

Abstract
An example method is provided in one example embodiment and may include receiving a packet for a subscriber at a gateway, wherein the gateway includes a local policy anchor for interfacing with one or more policy servers and one or more classifiers for interfacing with one or more service chains, each service chain including one or more services accessible by the gateway; determining a service chain to receive the subscriber'"'"'s packet; appending the subscriber'"'"'s packet with a header, wherein the header includes, at least in part, identification information for the subscriber and an Internet Protocol (IP) address for the local policy anchor; and injecting the packet including the header into the service chain determined for the subscriber.

7. One or more non-transitory tangible media encoding logic that include instructions for execution that, when executed by a processor, is operable to perform operations comprising:
-
receiving an update for a service at a local policy anchor included in a gateway, wherein the service is included in one or more service chains accessible by the gateway and wherein the update is at least one of a policy update and a charging update; determining if the local policy anchor has a session established with the service; communicating the update to a classifier within the gateway if the local policy anchor does not have a session established with the service; determining, by the classifier, one or more service chains including the service if the local policy anchor does not have a session established with the service; injecting by the classifier a packet including a service header containing the update into the one or more determined service chains including the service if the local policy anchor does not have a session established with the service; and communicating the update to the service from the local policy anchor if the local policy anchor has a session established with the service. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus, comprising:
-
a gateway; a memory element for storing data; and a processor that executes instructions associated with the data, wherein the processor and memory element cooperate such that the apparatus is configured for; receiving an update for a service at a local policy anchor included in the gateway, wherein the service is included in one or more service chains accessible by the gateway and wherein the update is at least one of a policy update and a charging update; determining if the local policy anchor has a session established with the service; communicating the update to a classifier within the gateway if the local policy anchor does not have a session established with the service; determining, by the classifier, one or more service chains including the service if the local policy anchor does not have a session established with the service; injecting, by the classifier, a packet including a service header containing the update into the one or more determined service chains including the service if the local policy anchor does not have a session established with the service; and communicating the update to the service from the local policy anchor if the local policy anchor has a session established with the service. - View Dependent Claims (14, 15, 16, 17)
