摘要： A method is provided in one example embodiment and includes receiving at a network element a packet associated with a flow and determining whether a flow cache of the network element includes an entry for the flow indicating a classification for the flow. The method further includes, if the network element flow cache does not include an entry for the flow, punting the packet over a default path to a classifying service function, in which the classifying service function classifies the flow and determines a control plane service function for handling the flow, and receiving from the classifying service function a service path identifier (“SPI”) of a service path leading to the determined control plane service function. The flow is subsequently offloaded from the classifying service function to the network element.

摘要： 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.

摘要： 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.

摘要： 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.
