PTP: Path-specified transport protocol for concurrent multipath transmission in named data networks

This paper introduces a compromise solution-Path-specified Transport Protocol (PTP). PTP supports both the label switching and the addressless routing schemes. Specifically, the label switching scheme allows 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 reduces the computational burden on routers and consequently increases the system scalability. The experimental results show that PTP significantly increases users' downloading rates and improves network throughput.
