Query: Capacity Scalability of Line Networks with Batched Codes   The capacity of line networks with buffer size constraints is an open, but
practically important problem. In this paper, we consider line networks formed
by discrete memoryless channels, and study the achievable rate of batched
codes, which include several existing coding schemes studied in literature for
line networks as special cases. A batched code has an outer code and an inner
code. The outer code encodes the information messages into batches, each of
which is a group of coded symbols, while the inner code performs recoding on
the symbols belonging to the same batch at all nodes that forwarding a batch.
Batched codes enable us to impose various block-length and buffer size
constraints by tuning coding parameters. Using a technique that captures the
communication bottleneck of line networks, we derive upper bounds on the
achievable rates of batched codes as functions of line network length for
several coding parameter sets. We also discuss specific recoding schemes that
can achieve rates of the same order of the line network length for these coding
parameter sets. Our results shed light on how to design large multi-hop network
communications in practical scenarios using a unified coding framework instead
of the traditional layered approach.
