Evaluation of the Aggregation Capability of the MPT Network Layer Multipath Communication Library and Multipath TCP

2019 Acta Polytechnica Hungarica  
Multipath communication techniques can bring in a new era for Cognitive Infocommunication, due to ensuring resilient and high-speed data transfer. In this paper, we evaluated the MPT network layer multipath communication library, which creates an UDP tunnel, based on the GRE in UDP tunnel protocol. We compared the aggregation capability of MPT to that of MPTCP, which stands for Multi-Path TCP and based on TCP sub-flows to aggregate the transmission capacities of different physical interfaces

In this article, we used 100 Mbps and 1 Gbps speed channels to compare the aggregation capabilities of these two different multipath communication solutions. We used several scenarios for the evaluation. We tested both IPv4 and IPv6 both as underlying and as encapsulation protocols. We used several channels up to 12 to evaluate the aggregation capabilities with the industry standard iperf tool, even with different numbers of iperf threads. Meanwhile we measured the CPU usage of the two examined multipath technologies to get further insight into their operation. On the basis of our measurement results, we also set up a mathematical model of their channel aggregation capabilities.
