    Abstract: An example method for distributed network address and port translation (NAPT) for migrating flows between service chains in a network environment is provided and includes distributing translation state for a flow traversing the network across a plurality of NAPT service nodes in the network, with packets belonging to the flow being translated according to the translation state, associating the flow with a first service chain at a flow classifier in the network, and updating the association when the flow migrates from the first service chain to a second service chain, with packets belonging to the migrated flow also being translated according to the translation state. The method may be executed at a pool manager in the network. In specific embodiments, the pool manager may include a distributed storage located across the plurality of NAPT service nodes.

    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 translation: 在一个实施例中提供的方法包括在第一分类器处接收数据流的第一数据分组，其中第一数据分组包括第一标识符。 该方法还包括确定与第一标识符相关联的第二分类器，其中第二分类器进一步与服务链环境的至少一个服务链相关联。 该方法还包括将第一数据分组转发到第二分类器。 第二分类器被配置为接收第一数据分组，确定要转发第一数据分组的至少一个服务链的特定服务链，并将第一数据分组转发到特定服务链。

    Abstract: In one embodiment, a router includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors. The one or more computer-readable non-transitory storage media include instructions that, when executed by the one or more processors, cause the router to perform operations including receiving software-defined networking in a wide area network (SD-WAN) policies from a component of an SD-WAN network. The operations also include establishing a session with a mobile device and receiving information associated with the mobile device in response to establishing the session with the mobile device. The operations further include filtering the SD-WAN policies based on the information associated with the mobile device to generate SD-WAN device-specific policies and communicating the SD-WAN device-specific policies to the mobile device.
