METHOD FOR SENDING AN ACKNOWLEDGEMENT TO AN INGRESS MESH POINT IN A MESH NETWORK AND A MEDIUM ACCESS CONTROL FRAME FORMAT

摘要

The present invention relates to a method for confirming the delivery of a data packet in a mesh network by sending an acknowledgement (ACK) to an ingress mesh point (IMP). A mesh network comprises a plurality of mesh points that are wirelessly linked together. A data packet sent by a station (STA) is received by an IMP. A MAC frame is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (EMP) in order to provide a service by the mesh network. The MAC frame includes a field comprising an IMP address and an EMP address. When the EMP, (or optionally an intermediate mesh point), receives a data packet successfully, the EMP or the intermediate mesh point sends an ACK to the IMP or preceding mesh point.

主权项

1. A method for routing a data packet using a mesh network having at least an ingress mesh point and an egress mesh point, the method comprising:
receiving a data packet that includes control information with a plurality of addresses and a flag, the flag indicating whether the data packet is in one of: (1) a first format in which the data packet includes a first address of the ingress mesh point and a second address of the egress mesh point or (2) a second format in which the data packet does not include the first address of the ingress mesh point or the second address of the egress mesh point; and on condition that the flag indicates that the data packet is in the first format, reading the second address of at least the egress mesh point.
