Abstract: Embodiments of the present invention provide a gateway system and a communication method. The gateway system includes: a control plane entity connected or integrated with a mobility management network element, and configured to allocate an IP address to user equipment and configure a data path for connecting a user plane entity with a radio access network (RAN), a packet data network (PDN) or another gateway. One or more user plane entities located between the PDN and the RAN and independent of the control plane entity, are configured to forward data on the data path configured by the control plane entity. The gateway system is composed of the control plane entity and the user plane entity, which are independent of each other. The number of user plane entities may be independently changed to adapt to the change of network traffic without replacing all gateway entities, thus making the network deployment more convenient and lower cost.

Abstract: A load balancing method is provided: A load balancer obtains an invalidation notification, where the invalidation notification includes an identifier of an invalid object on a target side, and the invalid object includes an invalid interaction node, an invalid session group on an interaction node, or an invalid session in a session group; the load balancer broadcasts the invalidation notification, where the invalidation notification is used to instruct an interaction node on a source side to delete recorded information about a load balancing protocol of the invalid object; and the load balancer reassigns an interaction node to an application interaction request when the load balancer receives the application interaction request sent by the interaction node on the source side and destination data in the application interaction request is empty. In this way, reliability of message exchanging is ensured when an interaction node is abnormal.

Abstract: A method includes receiving, by an ingress network element, a data packet, wherein an ingress flow entry is stored in the ingress network element. The ingress flow entry comprises flow description information and a processing network element indication, where the flow description information matches the data packet, and the processing network element indication is used to indicate a processing network element that processes the data packet after the ingress network element. The method further includes sending, by the ingress network element, the data packet to the processing network element according to the ingress flow entry, so that the processing network element performs context processing on the data packet.
