Abstract: The disclosed embodiments relate to a system that compresses and transmits packets. During operation, the system obtains packets-to-be-compressed at a compressor located at a transmitter that transmits packets through a channel over a network link to a decompressor located at a receiver. The system also obtains cross-layer information regarding the network link from lower-layer network entities in the transmitter. Next, the system uses the cross-layer information to generate estimations for a state of the channel and a state of the decompressor. The system then determines a compression level for the packets-to-be-compressed based on a compression policy and the estimations for the state of the channel and the state of the decompressor. The system subsequently generates packets-to-be-transmitted by compressing headers of the packets-to-be-compressed, wherein the headers are compressed at different levels based on the determined compression level.

The MTC device may determine channel metrics of the cells from the MTC communication and may identify a cell with which to associate from the channel metrics. The association may be to a best downlink cell or a best uplink cell based on the operating profile of the MTC device.

Abstract: The present invention discloses a service processing method and apparatus, which belong to the field of Internet technologies. After the AP and an STA first perform MAC address change notification and then establish a first MAC connection, the AP sends service data of the STA to the STA through the first MAC connection by using a resource related to a second MAC connection. Therefore, in a MAC address change process, there is no need to re-establish a resource at an upper layer of a MAC layer, and only a change in invoking a MAC layer resource is required at a layer at which the MAC layer resource is used. Time and a resource for processing a service can be reduced without affecting service continuity and stability of the upper layer. Therefore, the service is processed in a timely manner and service processing efficiency is improved.

Abstract: The disclosure relates to technology for supporting a virtual switch to change data plane providers on a framework supporting multiple data plane providers. A processing device receives a request to change a first data plane provider, where the virtual switch is configured with a topology on the first data plane provider to use a flow management protocol.
