Wireless adaptor and method for transmitting and receiving message

Abstract

A method for transmitting and receiving a message is provided. The method includes steps of providing a bridge device having a bridge hardware address and a first end, receiving a first message including a first hardware address, a first protocol address and a second protocol address from the first end, recording the first hardware address and the first protocol address on a table, replacing the first hardware address with the bridge hardware address, transmitting the first message to a second end having a second hardware address corresponding to the second protocol address; transmitting a second message including the first protocol address, the second protocol address, the bridge hardware address, and the second hardware address from the second end to the bridge device, replacing the bridge hardware address with the first hardware address according to the table; and transmitting the second message to the first end.

1 . A method for transmitting and receiving a message, comprising steps of 
 providing a bridge device having a bridge hardware address and a first end;    receiving a first message from said first end, wherein said first message comprises a first hardware address, a first protocol address and a second protocol address;    recording said first hardware address and said first protocol address on a table;    replacing said first hardware address with said bridge hardware address;    transmitting said first message to a second end having a second hardware address corresponding to said second protocol address;    transmitting a second message from said second end to said bridge device, wherein said second message comprises said first protocol address, said second protocol address, said bridge hardware address, and said second hardware address;    replacing said bridge hardware address with said first hardware address according to said table; and    transmitting said second message to said first end.    
   
   
       2 . The method according to  claim 1 , wherein said bridge device is a wireless bridge.  
   
   
       3 . The method according to  claim 1 , wherein said first end is a client end and said client end is one of an Ethernet end and a wireless adaptor.  
   
   
       4 . The method according to  claim 1 , wherein said second end is a server end.  
   
   
       5 . The method according to  claim 4 , wherein said server end is one of an access point (AP) and a second wireless bridge.  
   
   
       6 . The method according to  claim 4 , wherein said server end comprises a dynamic host configuration protocol (DHCP) server.  
   
   
       7 . The method according to  claim 1 , wherein said first message is an address resolution protocol (ARP) packet.  
   
   
       8 . A bridge device having a bridge hardware address, comprising: 
 a first end receiving a first message from a client end, wherein said first message comprises a first hardware address, a first protocol address, and a second protocol address;    a table recording said first hardware address and said first protocol address, wherein a transformation between said bridge hardware address and said first hardware address is based on said table;    a second end receiving a second message from a server end, wherein said second message has a second hardware address corresponding to said second protocol address;    wherein when said first message is received by said first end, said first hardware address is replaced by said bridge hardware address, and when said second message is received by said second end, said bridge hardware address is replaced by said first hardware address.    
   
   
       9 . The device according to  claim 8 , wherein said second message further comprises said first protocol address, said second protocol address, and said bridge hardware address.  
   
   
       10 . The device according to  claim 8 , wherein said second message having said second hardware address is transmitted from said first end to said client end.  
   
   
       11 . The device according to  claim 8 , wherein said bridge device is a wireless bridge.  
   
   
       12 . The device according to  claim 8 , wherein said client end is one of an Ethernet end and a wireless adaptor.  
   
   
       13 . The device according to  claim 8 , wherein said second end is one of an access point (AP) and a second wireless bridge.  
   
   
       14 . The device according to  claim 8 , wherein said bridge device is a wireless bridge.  
   
   
       15 . A bridge device having a bridge hardware address, comprising: 
 a first end receiving a first message from a client end, wherein said first message has a first hardware address and a first protocol address;    a table recording said first message, wherein a transformation between said bridge hardware address and said first hardware address is based on said table;    a second end receiving a second message from a server end, wherein said second message has a second hardware address;    wherein, when said first message is received by said first end, said first hardware address is replaced by said bridge hardware address, and when said second message is received by said second end, said bridge hardware address is replaced by said first hardware address.    
   
   
       16 . The device according to  claim 15 , wherein said first message further comprises a second protocol address.  
   
   
       17 . A bridge device having a bridge hardware address, comprising a table for recording a hardware address and a protocol address in a message.  
   
   
       18 . The device according to  claim 17 , wherein a transformation between said bridge hardware address and said hardware address is based on said table;  
   
   
       19 . The device according to  claim 17 , wherein said bridge device is a wireless bridge;  
   
   
       20 . The device according to  claim 17 , wherein said message is from a client end.  
   
   
       21 . The method according to  claim 17 , wherein said message further comprises a second protocol address.
