Abstract

Make-before-break roaming may be provided. A first packet and a second packet may be created. The first packet and the second packet may comprise replicants of one another. The first packet and the second packet may comprise a sequence number. The first packet may be received by a first link and the second packet may be received by a second link. The first packet may be forwarded from the first link and the second packet may be forwarded from the second link.

First claim

1 . A method comprising:
creating a first packet and a second packet, the first packet and the second packet comprising replicants of one another, wherein the first packet and the second packet comprise a sequence number; receiving the first packet by a first link and the second packet by a second link; and forwarding the first packet from the first link and the second packet from the second link.

2 . The method of claim 1 , wherein creating the first packet and the second packet is performed on an Ethernet network.

3 . The method of claim 1 , wherein creating the first packet and the second packet is performed on a wireless network.

4 . The method of claim 1 , further comprising receiving, by a computing device, the first packet and the second packet.

5 . The method of claim 4 , wherein the computing device comprises a client device.

6 . The method of claim 4 , further comprising eliminating one of the first packet and the second packet based on the sequence number.

7 . The method of claim 6 , further comprising resequencing, within a packet stream, one of the first packet and the second packet that was not eliminated based on the sequence number.

8 . A non-transitory computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:
creating a first packet and a second packet, the first packet and the second packet comprising replicants of one another, wherein the first packet and the second packet comprise a sequence number; receiving the first packet by a first link and the second packet by a second link; and forwarding the first packet from the first link and the second packet from the second link.

9 . The non-transitory computer-readable medium of claim 8 , wherein creating the first packet and the second packet is performed on an Ethernet network.

10 . The non-transitory computer-readable medium of claim 8 , wherein creating the first packet and the second packet is performed on a wireless network.

11 . The non-transitory computer-readable medium of claim 8 , further comprising receiving, by a computing device, the first packet and the second packet.

12 . The non-transitory computer-readable medium of claim 11 , wherein the computing device comprises a client device.

13 . The non-transitory computer-readable medium of claim 11 , further comprising eliminating one of the first packet and the second packet based on the sequence number.

14 . The non-transitory computer-readable medium of claim 13 , further comprising resequencing, within a packet stream, one of the first packet and the second packet that was not eliminated based on the sequence number.

15 . A system comprising:
a first memory storage; and a first processing unit coupled to the first memory storage, wherein the first processing unit is operative to:
create a first packet and a second packet, the first packet and the second packet comprising replicants of one another, wherein the first packet and the second packet comprise a sequence number;
receive the first packet by a first link and the second packet by a second link; and
forward the first packet from the first link and the second packet from the second link.

16 . The system of claim 15 , wherein the first processing unit being operative to create the first packet and the second packet is performed on an Ethernet network.

17 . The system of claim 15 , wherein the first processing unit being operative to create the first packet and the second packet is performed on a wireless network.

18 . The system of claim 15 , further comprising:
a second memory storage; and a second processing unit coupled to the second memory storage, wherein the second processing unit is operative to receive the first packet and the second packet.

19 . The system of claim 18 , wherein the second processing unit is disposed in a client device.

20 . The system of claim 18 , wherein the second processing unit is further operative to eliminate one of the first packet and the second packet based on the sequence number.
