Packet Forwarding Method, Path Reconstrucitng Method and State Transition Method For Avoiding Packet Loss During Handover

摘要

Provided is a method of packet forwarding over partial mesh network to avoid packet loss during handover. The method includes: based on first trigger information of a layer 2 obtained when a mobile node (MN) moves from a domain of a currently connected first BS to another domain, expecting a second BS of the domain to which the MN moves; if the first BS acquires second trigger information of the layer 2 indicating a disconnection between the first BS and the MN, forwarding packets destined for the MN to the second BS through the links; and if the second BS buffers the packets forwarded from the first BS and third trigger information of the layer 2 indicating a connection between the second BS and the MN, transferring the buffered packets to the MN.
