“…Furthermore, the code rate is defined, from an implementation point of view, as in [6]: the rate between source and coded symbols, which is different from the definition in [29]. Thus, the code rate used in this study represents the number of source symbols after which a coded symbol should be inserted.…”

“…This extension is subsequently converted into a portable plugin, integrated along with multipath and other transport features in the pluginized QUIC [7]. Garrido et al presented the first version of rQUIC [6], an extension of QUIC with an adaptive FEC. We improve the initial implementation by designing a more generic scheme, which might be configured to feature different coding solutions.…”

We introduce rQUIC, an integration of the QUIC protocol, and a coding module. rQUIC has been designed to feature different coding/decoding schemes and is implemented in go language. We conducted an extensive measurement campaign to provide a thorough characterization of the proposed solution. We compared the performance of rQUIC with that of the original QUIC protocol for different underlying network conditions as well as different traffic patterns. Our results show that rQUIC not only yields a relevant performance gain (shorter delays), especially when network conditions worsen, but also ensures a more predictable behavior. For bulk transfer (long flows), the delay reduction almost reached 70% when the frame error rate was 5%, while under similar conditions, the gain for short flows (web navigation) was ≈ 55%. In the case of the video streaming the QoE gain (p1203 metric) was, approximately, 50%.

“…In that case, robustness is more important than extra data and battery usage. Thus, the action set can have redundancy characteristics, e.g., packet duplication or FEC [57], etc. The reward should also be modified so that it can be mathematically proven to have a delay bound.…”

Multipath transport protocols utilize multiple network paths (e.g., WiFi and cellular) to achieve improved performance and reliability, compared with their single-path counterparts. The scheduler of a multipath transport protocol determines how to distribute the data packets onto different paths. However, state-of-the-art multipath schedulers face the challenge when dealing with heterogeneous paths with dynamic path characteristics (i.e., packet loss, fluctuation of delay). In this paper, we propose Peekaboo, a novel learning-based multipath scheduler that is aware of the dynamic characteristics of the heterogeneous paths. Peekaboo is able to learn scheduling decisions to adopt over time based on the current path characteristics and dynamicity levels -from both deterministic and stochastic perspectives. We implement Peekaboo in Multipath QUIC (MPQUIC) and compare it with state-of-the-art multipath schedulers for a wide range of dynamic heterogeneous environments, upon both emulated and real networks. Our results show that Peekaboo outperforms the other schedulers by up to 31.2% in emulated networks and up to 36.3% in real network scenarios.

This article proposes a discussion on the strengths, weaknesses, opportunities, and threats related to the deployment of QUIC end-to-end from a satellite-operator point-of-view. The deployment of QUIC is an opportunity for improving the quality of experience when exploiting satellite broadband accesses. Indeed, the fast establishment of secured connections reduces the transmission time of short files.Moreover, removing transport-layer performance-enhancing proxies reduces the cost of network infrastructures and improves the integration of satellite systems.However, the congestion and flow controls at end points are not always suitable for satellite communications due to the intrinsic high bandwidth-delay product. Further acceptance of QUIC in satellite systems would be guaranteed if its performance in specific use cases were increased. Based on an emulated platform and on open-source software, this paper proposes values of performance metrics as one piece of the puzzle. The final performance objective requires consensus among the different actors. The objective should at least provide acceptable performance for satellite operators to allow QUIC traffic but reasonable enough to keep QUIC deployable on the Internet.
