Abstract

Method for MAC addressing in a device operating in OSI layers 2 and 3, the method comprising the steps of: receiving a connection request ( 400 ) from a first 2MAC client ( 102 ) wherein the request comprises: the client's ( 102 ) first MAC address gMAC ( 406 ) being globally unique, the client's ( 102 ) second MAC address uMAC ( 407 ) being unique within a local 2MAC clients ( 102, 105 ) group; and a targets IP address and port ( 408 ); establishing ( 401 ) a connection between the server ( 108 ) and the first 2MAC client ( 102 ). Additionally, there is presented a method for MAC addressing in a device operating in OSI layer 2 or OSI layers 2 and 3, the method comprising: constructing ( 253 ) a packet from a first 2MAC client ( 102 ) targeted at another 2MAC client ( 105 ) wherein the packet comprises: the client's ( 102 ) first MAC address gMAC ( 406 ) being globally unique and the client's ( 102 ) second MAC address uMAC ( 407 ) being unique within a local 2MAC clients ( 102, 105 ) group.

First claim

1 . Method for MAC addressing, in a client-server arrangement, in a device operating in OSI layers 2 and 3, the method being characterized in that it comprises the steps of:
receiving a connection request ( 400 ) from a first 2MAC client ( 102 ) wherein the request comprises:
the client's ( 102 ) first MAC address gMAC ( 406 ) being globally unique,
the client's ( 102 ) second MAC address uMAC ( 407 ) being unique within a local 2MAC clients ( 102 , 105 ) group;
and a target's IP address and port ( 408 );
establishing ( 401 ) a connection between the server ( 108 ) and the first 2MAC client ( 102 ).

2 . The method according to claim 1 characterized in that it further comprises:
receiving ( 402 ) data from a client ( 114 ) addressed to the 2MAC client ( 102 );
constructing an Ethernet packet ( 403 ), based on the received ( 402 ) data, for the 2MAC client comprising:
the client's ( 102 ) first MAC address gMAC ( 406 ) being globally unique,
the target client's ( 105 ) first MAC address gMAC ( 406 ) being globally unique,
the IP options field of the Ethernet packet comprising the client's ( 102 ) second MAC address uMAC ( 407 ) being unique within a local 2MAC clients ( 102 , 105 ) group;

transmitting ( 404 ) the packet to the 2MAC client ( 102 ).

3 . The method according to claim 1 characterized in that it further comprises:
sending data received from the 2MAC client ( 102 ) to the client ( 114 ).

4 . Method for MAC addressing, in a client to client transmission, in a device operating in OSI layer 2 or OSI layers 2 and 3, the method being characterized in that it comprises the steps of:
constructing ( 253 ) an Ethernet packet from a first 2MAC client ( 102 ) targeted at another 2MAC client ( 105 ) comprising:
the client's ( 102 ) first MAC address gMAC ( 204 ) being globally unique,
the target client's ( 105 ) first MAC address gMAC ( 203 ) being globally unique,
the IP options field of the Ethernet packet comprising the client's ( 102 ) second MAC address uMAC ( 214 ) and the target client's ( 105 ) second MAC address uMAC ( 213 ) both being unique within a local 2MAC clients ( 102 , 105 ) group;
transmitting ( 254 ) the constructed packet.

5 . The method according to claim 2 characterized in that the IP options field comprises option length ( 212 ) word in order to ensure consistency of the packet.

6 . The method according to claim 2 characterized in that the content of the IP options field is selected with regard to IANA-IP option numbers and RFC6814.

7 . The method according to claim 6 characterized in that the IP options field comprises uMAC option type identifier, uMAC option length identifier, the destination uMAC, the own uMAC,

8 . The method according to claim 7 characterized in that the destination uMAC and the own uMAC are 6-byte addresses.

9 . A non-transitory computer readable medium storing computer-executable instructions performing all the steps of the computer-implemented method according to claim 1 when executed on a computer.

10 . A computer network being characterized in that it comprises:
at least one 2MAC client ( 102 , 105 ) having assigned:
the client's ( 102 ) first MAC address gMAC ( 406 ) being globally unique, wherein the gMAC ( 406 ) address is the same for all 2MAC clients;
the client's ( 102 ) second MAC address uMAC ( 407 ) being unique within a local 2MAC clients ( 102 , 105 ) group ( 101 ).

11 . The computer network according to claim 10 characterized in that it further comprises:
at least one 2MAC server ( 108 ) configured to avow the communication of the devices in a 2MAC group ( 101 ) and the remainder of the clients ( 112 , 114 ) wherein any 2MAC client, communicating with another client outside of the group ( 101 ), does it via the 2MAC sever ( 108 ) using this server's MAC address ( 109 ) as destination address.

12 . The computer network according to claim 10 characterized in that the 2MAC client ( 102 , 105 ) has an IP address assigned ( 408 ).

13 . The computer network according to claim 10 characterized in that it further comprises a DHCP server ( 110 ) wherein all 2MAC clients receive same responses to DHCP queries and thus have the same IP address assigned by the DHCP server.
