Investigating the multipath extension of the GRE in UDP technology

A novel network layer multipath solution is proposed.MPT is a multipath extension of the GRE in UDP technology.Different mappings of tunnel traffic to paths are supported.Open control interface facilitates experimenting. Display Omitted MPT is a novel multipath technology based on the GRE in UDP tunnel specification. In this paper, the conceptual architecture of MPT is disclosed. The designed structure of MPT includes several useful components: the possibility for external software modules to change the run-time parameters (by using the control interface), the choice between flow-based and packet based mappings of tunnel traffic to paths, as well as optional guarantee of in-order packet delivery to the application. The throughput aggregation performance of MPT is investigated in both laboratory and production network environment. The production network measurements proved that MPT is capable for super-aggregation (i.e. the aggregated throughput is higher than the algebraic sum of the throughput of the paths).
