Packet buffering based on hop count number in a multi-hop network

摘要

A source node of a multi-hop network is provided with a route table in which a number of routes from the node to all destinations are mapped to hop count numbers. In response to a request for transmission of data, the node determines a hop count number from the route table corresponding to a route indicated in the request and segments the data into a number of data segments according to the hop count number. The data segments are converted into packets and transmitted. In a transit node, the packets are placed into one of a set of queuing buffers that corresponds to the hop count number of the packets. The stored packets are scheduled for transmission according to their hop count number.
