Abstract The communication capacity of a network of line topology is studied, where only two adjacent nodes are connected by communication channels, and the intermediate network nodes have a buffer size constraint. Let L be the number of hops from the source node to the destination node. For general channels, we provide schemes to achieve Ω(1/ln L) rates using a buffer of size B1+B2 bits, where B1 does not change with L and B2 = O(lnln L). In particular, B1 bits of the buffer are used to store the data generated from the communication messages, and the other B2 bits of the buffer are used to store the status of counters with the maximum value O(ln L).
