Wireless communication has seen a tremendous growth in the last decades. Continuing on this trend, wireless multi-hop networks are nowadays used or planned for use in a multitude of contexts, spanning from Internet access at home to emergency situations. The Transmission Control Protocol (TCP) provides reliable and ordered delivery of a data and is used by major Internet applications such as we...

We study the performance of TCP-based media transport when combined with packet path diversity (PPD) in the Internet. We present a simple PPD-TCP transmission scheme where the acknowledgments (ACKs) from the receiver are duplicated and sent across independent network paths. We also investigate a PPD-TCP scheme where in addition to path-diversified ACKs on the backward path, packet path diversit...

Standard TCP is the de facto reliable transfer protocol for the Internet. It is designed to establish a reliable connection using only a single network interface. However, standard TCP with single interfacing performs poorly due to intermittent node connectivity. This requires the re-establishment of connections as the IP addresses change. Multi-path TCP (MPTCP) has emerged to utilize multiple ...

The canonical multi-path NUM model which is extended directly from the single-path NUM has been studied widely in the literature. Most of the previous approaches do not specify the case of subflows on paths with different characteristics. Moreover, the transport protocol derived from the canonical multi-path NUM exhibits flappiness in the subflows because of the non-strictly convexity of the op...

Advances in cellular technology have increased the demand of accessing the Internet dramatically. Cellular technology not only enables mobility, but also allows redundant connectivity using multiple wireless paths to improve availability, reliability, and performance. Multiple paths enable the potential to shift traffic from broken or congested paths to higher-quality ones as traffic characteri...

We propose an adaptive flow-level multi-path routing-based traffic engineering solution for an IP backbone network carrying TCP/IP traffic. Incoming TCP flows are switched between two explicitly routed paths, namely the primary and secondary paths (PP and SP), for resilience and potential goodput improvement at the TCP layer. In the proposed architecture, PPs receive a preferential treatment ov...

MPTCP is proposed by IETF working group, it allows a single TCP stream to be split across multiple paths. It has obvious benefits in performance and reliability. MPTCP has implemented in Linux-based distributions that can be compiled and installed to be used for both real and experimental scenarios. In this article, we provide performance analyses for MPTCP with a laptop connected to WiFi acces...

In this paper we analyze the performance of a TCP-like ow control mechanism. The transmission rate is considered to increase linearly in time until the receipt of a congestion notiication (via loss detection in context of TCP) where the transmission rate is multiplicatively decreased. We introduce a general model based on a multi-state Markov chain for the moments at which the congestion is det...

Parallel TCP, which opens multiple TCP connections over a single path, and Multi-Pathing, which concurrently uses multiple paths to transfer data, have both been proved to be effective methods to improve end-to-end throughput. How much throughput can we ultimately achieve between a source and a destination if we use multiple overlay paths and open multiple TCP connections on each used path? In ...
