Abstract:
1. A method for improving packet loss due to fast optical power fades in a Free Space Optical (“FSO”) communication link, comprising: obtaining, by a network node, channel fade statistics for the FSO communication link, where the channel fade statistics are determined using information specifying at least one of an optical power parameter of the FSO communication link and an environmental parameter; analyzing, by the network node, the channel fade statistics to dynamically determine if a redundant packet transmission is required to mitigate fast optical power fading; if it is determined that the redundant packet transmission is required, performing first operations, by the network node, at a data link layer of a protocol stack to generate a plurality of first packets, each having at least a first sequence number disposed between a data link layer header and a network layer header; and automatically transmitting the plurality of first packets from the network node over the FSO communication link at least two times without any request by another network node to transmit the plurality of first packets.
