Data access method and network device using the same

Abstract

This invention provides a data access method and a network device. The network device includes an external storage interface, a network server, and a digitizer. The external storage interface is configured to couple to external storage resources. The network server is coupled to the external storage interface and configured to establish a network shared data area supporting a first network communication protocol, wherein the network shared data area emulates the external storage resources as local storage devices. The digitizer is coupled to the network server and supports a second network communication protocol, wherein the digitizer receives data access requests corresponding to the second network communication protocol and, in response to the data access requests, accesses the external storage resources through the network shared data area and the external storage interface.

Claims

1. A network device, comprising: An external storage interface configured to couple to an external storage resource; A network server, coupled to the external storage interface and configured to establish a network shared data area supporting a first network communication protocol, wherein the network shared data area emulates the external storage resource as a local storage device; and a digitizer, coupled to the network server and supporting a second network communication protocol, wherein the digitizer receives a data access request corresponding to the second network communication protocol and, in response to the data access request, accesses the external storage resource through the network shared data area and the external storage interface.

2. The network device as claimed in claim 1, wherein the external storage resource includes a cloud storage space.

3. The network device as claimed in claim 1, wherein the first network communication protocol includes a Samba protocol.

4. The network device as claimed in claim 1, wherein the second network communication protocol includes a Digital Living Network Alliance (DLNA) protocol.

5. The network device as claimed in claim 1, wherein the network device includes a router.

6. The network device as claimed in claim 1, wherein the network device is not provided with a general serial bus interface for connecting an external storage device.

7. A data access method, executed by a network device, comprising: Couple an external storage resource to the external storage interface of the network device; Establish a network shared data area supporting a first network communication protocol and simulate the external storage resource as a local storage device; and receive a data access request corresponding to a second network communication protocol, and access the external storage resource through the network shared data area and the external storage interface in response to the data access request.
