Query: PTP: Path-specified Transport Protocol for Concurrent Multipath
  Transmission in Named Data Networks   Named Data Networking (NDN) is a promising Future Internet architecture to
support content distribution. Its inherent addressless routing paradigm brings
valuable characteristics to improve the transmission robustness and efficiency,
e.g. users are enabled to download content from multiple providers
concurrently. However, multipath transmission NDN is different from that in
Multipath TCP, i.e. the "paths" in NDN are transparent to and uncontrollable by
users. To this end, the user controls the traffic on all transmission paths as
an entirety, which leads to a noticeable problem of low bandwidth utilization.
In particular, the congestion of a certain path will trigger the traffic
reduction on the other transmission paths that are underutilized. Some
solutions have been proposed by letting routers balance the loads of different
paths to avoid congesting a certain path prematurely. However, the complexity
of obtaining an optimal load balancing solution (of solving a Multi-Commodity
Flow problem) becomes higher with the increasing network size, which limits the
universal NDN deployments. This paper introduces a compromising solution -
Path-specified Transport Protocol (PTP). PTP supports both the label switching
and the addressless routing schemes. Specifically, the label switching scheme
facilitates users to precisely control the traffic on each transmission path,
and the addressless routing scheme maintains the valuable feature of retrieving
content from any provider to guarantee robustness. As the traffic on a
transmission path can be explicitly controlled by consumers, load balancing is
no longer needed in routers, which reduce the computational burden of routers
and consequently increase the system scalability. The experimental results show
that PTP significantly increases the users' downloading rates and improved the
network throughput.
