Abstract: A load balancing system implemented in a data center network (DCN) includes a controller and a server. The controller generates topology information of the DCN based on information about a network node in the DCN, and sends the topology information to the server. The server obtains a data flow and selects a forwarding path corresponding to the data flow from a plurality of load balancing paths, wherein the plurality of load balancing paths are generated based on the topology information.

Abstract: Example communication methods and apparatus in a wireless network are described. One example communication method includes establishing dual connections to a first access network device and a second access network device by a terminal device. A connection that is between the terminal device and the first access network device and that is included in the dual connections is a radio resource control (RRC) connection. The terminal device receives first configuration information sent by the first access network device. The first configuration information includes signaling radio bearer (SRB) configuration information of the second access network device and a trigger condition for using the SRB configuration information. When the trigger condition is met, the terminal device uses the SRB configuration information of the second access network device to establish an RRC connection to the second access network device.
