Abstract: A method provided in one embodiment includes receiving a first data packet of a data flow at a first classifier in which the first data packet includes a first identifier. The method further includes determining a second classifier associated with the first identifier in which the second classifier is further associated with at least one service chain of a service chain environment. The method still further includes forwarding the first data packet to the second classifier. The second classifier is configured to receive the first data packet, determine a particular service chain of the at least one service chain to which the first data packet is to be forwarded, and forward the first data packet to the particular service chain.

Abstract: A method provided in one embodiment includes receiving, at a first network element, a first data packet of a data flow, wherein the data flow is associated with a subscriber. The method further includes receiving subscriber information associated with the subscriber, and encapsulating the subscriber information with the first data packet to form an encapsulated data packet. The method still further includes determining a service chain including one or more services to which the encapsulated data packet is to be forwarded, and forwarding the encapsulated data packet to the service chain.

Abstract: In an embodiment, a method is provided for enabling in-band data exchange between networks. The method can comprise receiving, by a first enveloping proxy located in the first network, at least one regular secure sockets layer (SSL) record for a SSL session established between a client and a server; receiving the data from a network element located in the first network; encoding the data into at least one custom SSL record; and transmitting the at least one regular SSL record and the at least one custom SSL record to an enveloping proxy. In another embodiment, a method can comprise receiving at least one regular secure sockets layer (SSL) record and at least one custom SSL record for a SSL session established between a client and a server; extracting the data from the at least one custom SSL; transmitting the at least one regular SSL record.

Abstract: A method is provided in one example and includes receiving a request from a first network element associated with a first network for establishing a first communication session between the first network element to a first user device associated with a second network. The request includes a first user identifier used to identify a first user associated with the first user device within the first network. The method further includes translating the first user identifier to a second user identifier in which the second user identifier is used to identify the first user within the second network. The method still further includes sending a first query including the second user identifier to a second network element, and receiving a first response message including quality of service information indicated by a policy associated with the second user identifier.
