20150156107 | Method, Controller, and System for Processing Data Packet - A method, a controller, and a system for processing a data packet are disclosed. The method includes receiving, by a controller, a data packet that is reported by a switch and does not match a forwarding rule; after it is determined that a type of the data packet is a broadcast data packet, generating a forwarding rule for the data packet, where the forwarding rule includes an action attribute being discarded; and sending the forwarding rule of the data packet to the switch, so that when receiving the data packet again, the switch discards the data packet according to the action attribute of the forwarding rule. In the present invention, a broadcast storm on a network can be avoided without shielding a port of a switch. Therefore, for a fully-connected network, a forwarding capability of a port and a quantity of available transmission links on the network are ensured. | 06-04-2015 |
20150195201 | Topology Stratification Method and Apparatus, and Flooding Processing Method and Apparatus - The method includes the following steps. First, a controller receives a data packet that is reported by a switch connected to a source host; then the controller searches a local media access control (MAC) address table of physical addresses of devices to determine whether a destination address of the data packet exists, and the controller acquires a destination port if no destination address of the data packet exists, where the destination port is a port of a switch connected to a destination host, and the destination host is another host different from the source host; and finally, the controller uses the destination port as a destination address to generate a routing table, and sends the routing table to the switch connected to the source host, so that the switch connected to the source host forwards the data packet according to the routing table. | 07-09-2015 |

20120296956 | Method and system for synchronizing data between QUALCOMM platform terminal and PC side - The present disclosure discloses a method for synchronizing data between a Qualcomm platform terminal and a Personal Computer (PC) side, which comprises the following steps: the DIAG module of the Qualcomm platform terminal receives a request packet from the PC side, converts the request packet into a pseudo request packet, and transmits the pseudo request packet to an application layer module of the Qualcomm platform terminal via an Original Equipment Manufacturer (OEM) layer module of the Qualcomm platform terminal; the application layer module fills a pseudo response packet according to the pseudo request packet transmitted from the OEM layer module and then transmits the pseudo response packet to the DIAG module via the OEM layer module; and the DIAG module converts the pseudo response packet transmitted from the OEM layer module into a real response packet and then transmits the real response packet to the PC side. The present disclosure also discloses a system for synchronizing data between a Qualcomm platform terminal and a PC side. In the present disclosure, the implementations of a bottom layer and an application layer are not mixed together any more, which reduces code coupling degree, avoids the occurrence of a fault in a data synchronization process and facilitate the extension of new functions. | 11-22-2012 |
20120306871 | Method and apparatus for redrawing widget - A method for redrawing a Widget is provided, which specifically includes: creating a three-dimensional container, and inserting a Widget with plane coordinates and a Z coordinate into the 3D container; informing the three-dimensional container when the Widget is changed; determining, by the three-dimensional container, whether the Z coordinate of the changed Widget is equal to a Z coordinate of another Widget, if yes, performing a redrawing according to a Widget redrawing flow on the same plane, otherwise, redrawing the changed Widget and completing the redrawing. An apparatus for redrawing a Widget is further provided. By means of the above method and apparatus, Widgets in different layers can be redrawn without a redundant redrawing operation, so that a refresh efficiency of a display interface is improved | 12-06-2012 |
20120307311 | Image copying method and device - The disclosure discloses an image copying method, which includes the steps of: copying, an image to be copied, to a destination address line by line, in the case of the image to be copied having a width of one pixel; copying, the image to be copied, to the destination address by a number of bytes according to a size of the image to be copied, in the case of the image to be copied not having a width of one pixel. The image copying method can save the image copying time and deduce the Central Processing Unit (CPU) occupation rate. | 12-06-2012 |
