    Abstract: An example method for load balancing in a network environment is provided and includes receiving a packet from a first stage load-balancer in a network environment, where the packet is forwarded from the first stage load-balancer to one of a plurality of second stage load-balancers in the network according to a hash based forwarding scheme, and routing the packet from the second stage load-balancer to one of a plurality of servers in the network according to a per-session routing scheme. The per-session routing scheme includes retrieving a session routing state from a distributed hash table in the network. In a specific embodiment, the hash based forwarding scheme includes equal cost multi path routing. The session routing state can include an association between a next hop for the packet and the packet's 5-tuple representing a session to which the packet belongs.

    Abstract: A method is provided in one example embodiment and may include communicating information between a plurality of network function virtualized (NFV) based applications; and creating at least one service chain using at least two of the plurality of NFV-based applications based on the information communicated between the plurality NFV based applications. In some instances, the information can be communicated using border gateway protocol (BGP) exchanges between the NFV-based applications. In some instances, the information can include at least one of: next-hop address information for one or more ingress points of a particular NFV-based application; one or more capabilities by which a particular NFV-based application can receive data on one or more ingress points; and a method by which one or more egress points of a previous NFV-based application in a particular service chain is to perform load balancing for a subsequent NFV-based application in the particular service chain.

    Abstract: A method is provided in one example embodiment and includes sending, by a first entity associated with an access network, a first request message including a session identifier associated with a user session to a second entity associated with a core network. The method further includes establishing a first control channel with the second entity in which the first control channel is associated with the session identifier. The first control channel is an in-band channel between the first entity and the second entity. The method further includes receiving policy information associated with the user session from the second entity using the first control channel. The policy information is indicative of one or more policies to be applied in the access network to user data associated with the user session.
