Abstract: The present invention provides a media gateway device and a method for forwarding data frames. The media gateway device comprises: a master module, a switch module, a relay access module and a media resource module; the switch module comprises three independent Virtual Local Area Networks (VLANs), i.e., a first VLAN, a second VLAN and a third VLAN, respectively; the media resource module is connected to the switch module through the second VLAN, and the switch module is connected to an external Internet Protocol (IP) packet network through the third VLAN; the media gateway device further comprises a network layer static routing table. By using the media gateway device and the method for forwarding data frames according to the present invention, the number of the external interfaces of the media gateway device can be reduced, and the interface of the switch module can be managed by the VLAN.

Abstract: A method for accessing data is provide, the method includes: receiving a first address and identification information used to identify an address type; and when the identification information indicates a logical address type, converting the first address into a first physical address, and accessing at least one corresponding flash memory chip in the storage device; or when the identification information indicates a physical address type, directly accessing at least one corresponding flash memory chip in the storage device. When the storage device is accessed, a type of an accessed address is determined according to the identification information. If the address is a logical address, the storage controller maps the logical address to a physical address and accesses the physical address; or if the address is a physical address, the storage controller directly accesses the physical address sent by the host.

Abstract: The present invention relates to the field of communications technologies and discloses a phase shifter and a feed network. The phase shifter includes at least one phase shift component. The phase shift component includes a substrate, a microstrip coupling structure disposed on a first plane of the substrate, a microstrip transmission line connected to and coplanar with the microstrip coupling structure, and a microstrip/coplanar-waveguide coupling structure, where the microstrip/coplanar-waveguide coupling structure includes a microstrip connected to and coplanar with the microstrip transmission line, and a coplanar waveguide disposed opposite to the microstrip on the substrate and coupled with the microstrip. A phase shifter using a microstrip/coplanar-waveguide coupling structure has a small volume and costs low, thereby facilitating feed network design.
