Abstract

In a mesh network, when a wireless mesh link exists between a first mesh access point and a second mesh access point, the first mesh access point can deliver a multicast packet to the second mesh access point through the wireless mesh link. When the second mesh access point determines that the multicast packet from the first mesh access point is a redundant packet, the second mesh access point will send a multi-path notice to the first mesh access point. After receiving the multi-path notice, the first mesh access point stops delivering the multicast packet through the path.

Claims (14)

1. A method of delivering multicast packets for a mesh network, comprising: establishing a first wireless mesh link between a first mesh access point and a second mesh access point; establishing a second wireless mesh link between the second mesh access point and a third mesh access point; the second mesh access point receiving a multicast packet from the first mesh access point through the first wireless mesh link; the second mesh access point receiving the multicast packet from the third mesh access point through the second wireless mesh link; the second mesh access point sending a multi-path notice to the third mesh access point; and the third mesh access point stopping delivering a subsequent multicast packet to the second mesh access point after receiving the multi-path notice.

2. The method of claim 1 , wherein the step of the second mesh access point sending the multi-path notice to the third mesh access point is when the second mesh access point determines the multicast packet from the third mesh access point as a redundant.

3. The method of claim 1 , wherein the third mesh access point stops delivering the subsequent multicast packet to the second mesh access point during a predetermined period after receiving the multi-path notice.

4. The method of claim 1 , further comprising:

establishing a third wireless mesh link between the first mesh access point and the third mesh access point; and

the third mesh access point receiving the multicast packet from the first mesh access point through the third wireless mesh link.

5. The method of claim 4 , further comprising:

the third mesh access point receiving the multicast packet from the second mesh access point through the second wireless mesh link; and

the third mesh access point sending the multi-path notice to the second mesh access point.

6. The method of claim 5 , wherein the step of the third mesh access point sending the multi-path notice to the second mesh access point is when the third mesh access point determines the multicast packet from the second mesh access point as a redundant.

7. The method of claim 5 , further comprising:

the second mesh access point stopping delivering the subsequent multicast packet to the third mesh access point during a predetermined period after receiving the multi-path notice.

8. The method of claim 1 , wherein the multi-path notice comprises a medium access control (MAC) address of the first mesh access point.

9. The method of claim 1 , wherein the multi-path notice is provided according to the standard of IEEE 802.11 and 802.11s.
