摘要： A data flow is received from a mobile network relating to a mobile subscriber. Subscriber data is received for the subscriber identifying a service path corresponding to the subscriber and at least one service policy corresponding to the subscriber, the service path including a set of network service nodes in a plurality of network service nodes. Packets of the data flow are routed according to the service path, the packets corresponding to a request for a resource. At least one packet is appended with service header data identifying the service policy. Each service node performs at least one service based on received request data, each service node in the set of service nodes performing a service defined in a service subscription of the subscriber. At least one particular service node in the set of network service nodes performs a particular service based at least in part on the service policy.

摘要： A control plane (CP) entity is to adaptively reroute user plane traffic of a mobile node (MN) with use of a segment routing (SR) for IPv6. A message indicating an attachment of the MN to the mobile network is received selecting a first user plane (UP) anchor node. A first set of home network prefixes (HNPs) are allocated to the MN. An IP traffic flow using a first HNP prefix is established between the MN and a correspondent node (CN) along a first network path—defined at least in part by the first UP anchor node and an anchor node of the CN. In response to a handover of the MN, a message indicating a subsequent attachment of the MN is received selecting a second UP anchor node. The second UP anchor node is instructed to host the first HNP prefix previously allocated by the first UP anchor node.

摘要： A method provided in one embodiment includes receiving, at a packet gateway, a first binding update message from a mobile access gateway. The first binding update message has a destination address associated with a local mobility anchor. The method further includes extracting at least one session identifier associated with the mobile access gateway from the first binding update message, constructing an option field including the at least one session identifier, and appending the option field to the first binding update message to form a second binding update message. The method further includes sending the second binding update message to the local mobility anchor.
