Abstract

A network relay apparatus and method using a software module that easily support various network protocols and new network protocols. The network relay apparatus includes a first modem unit communicating with a first network using a first protocol, a second modem unit communicating with a second network using a second protocol, a bridge unit converting data to be suitable for the first and second protocols when the data is exchanged between the first modem unit and the second modem unit, and a controller generating the first and second modem units and the bridge unit in a software manner.

Claims

1. A network relay apparatus comprising:

a storage unit configured to store program files that are configured to implement one or more signal processors; and

a controller configured to selectively load program files for implementing the one or more signal processors needed to perform modem functions stored in the storage unit, and configured to dynamically create each of a first modem unit, a second modem unit and a bridge unit, wherein the first, second, and bridge units are generated via only software,

wherein each of the first modem unit and the second modem units is dynamically created by dynamically combining a pre-stored set of the one or more signal processors needed to perform modem functions,

wherein the one or more signal processors are generated via only software, and

wherein the first modem unit is configured to communicate with a first network using a first protocol, the second modem unit is configured to communicate with a second network using a second protocol, and the bridge unit is configured to convert data to be suitable for the first and second protocols when the data is exchanged between the first modem unit and the second modem unit.

2. The network relay apparatus of claim 1, wherein each of the one or more signal processors is one of reused to create one or more modem units and used for different modem units at a same time.

3. The network relay apparatus of claim 1, wherein the controller further creates at least one modem unit configured to communicate with a network using a protocol different from one of the first and second protocols.

6. The network relay apparatus of claim 1, wherein one of the one or more signal processors is at least at least a Fourier transform (FFT) processor, a carrier sense multiple access with collision avoidance (CSMA/CA) processor, or a quadrature phase shift keying (QPSK) processor.

4. A network relay method comprising:

decoding, by a first modem unit, a signal received from a first network using a first protocol;

converting, by a bridge unit, the decoded signal to be suitable for a second protocol; and

coding, by a second modem unit, the converted signal and transmitting, by the second modem unit, the coded signal to a second network using the second protocol,

wherein each of the first modem unit, the second modem unit, and the bridge unit are dynamically created via only software,

wherein each of the first modem unit and the second modem units is dynamically created by dynamically combining a pre-stored set of one or more signal processors needed to perform modem functions, wherein the one or more signal processors are generated via only software by selectively loading program files for implementing the one or more signal processors needed to perform the modem functions stored in a storage unit.

5. The network relay method of claim 4, wherein each of the one or more signal processors is one of reused to create one or more modem units and used for different modem units at a same time.

7. The network relay method of claim 4, wherein one of the one or more signal processors is at least at least a Fourier transform (FFT) processor, a carrier sense multiple access with collision avoidance (CSMA/CA) processor, or a quadrature phase shift keying (QPSK) processor.
