Online Resource Inference in Network Utility Maximization Problems

The amount of transmitted data in computer networks is expected to grow considerably in the future, putting more and more pressure on the network infrastructures. In order to guarantee a good service, it then becomes fundamental to use the network resource ...

A Bayesian Bandit Approach to Adaptive Delay-based Congestion Control

Pascal Frossard, Stefano D'Aronco

Adapting the transmission rate of video telephony Internet applications in order to guarantee the maximal communication quality is still an open and extremely challenging problem. The congestion control algorithm, which is the algorithm responsible for adj ...

Network utility maximization for delay-sensitive applications in unknown communication settings

Stefano D'Aronco

In the last decades the Internet traffic has greatly evolved. The advent of new Internet services and applications has, in fact, led to a significant growth of the amount of data transmitted, as well as to a transformation of the data type. As a matter of ...

Distributed Rate Allocation in Switch-Based Multiparty Videoconferencing System

Pascal Frossard, Sergio Mena, Stefano D'Aronco

Multiparty videoconferences, or more generally multiparty video calls, are gaining a lot of popularity as they offer a rich communication experience. These applications have, however, large requirements in terms of both network and computational resources ...

Switching Between Loss-Based and Delay-Based Mode for Real-Time Media Congestion Controllers

Sergio Mena, Stefano D'Aronco

Congestion control may be provided. A set of rules may allow a congestion control process to switch from delay-mode to loss-mode (e.g., in the presence of loss-based flows) and back to delay-mode (e.g., when loss-based flows stop). Fairness properties of t ...

Improved Utility-based Congestion Control for Low-Delay Communication

Pascal Frossard, Sergio Mena, Laura Toni, Stefano D'Aronco

Due to the presence of buffers in the inner network nodes, each congestion event leads to buffer queueing and thus to an increasing end-to-end delay. In the case of delay sensitive applications, a large delay might not be acceptable and a solution to prope ...

Price-based Controller for Utility-aware HTTP Adaptive Streaming

Pascal Frossard, Laura Toni, Stefano D'Aronco

HTTP Adaptive Streaming (HAS) permits to efficiently deliver video to multiple heterogenous users in a fully distributed way. This might however lead to unfair bandwidth utilization among HAS users. Therefore, network-assisted HAS systems have been propose ...

Congestion control for media flows

Sergio Mena, Laura Toni, Stefano D'Aronco

An apparatus can include a congestion controller at a source endpoint node of a network that is configured to send substantially real-time media data at a variable sending rate to another endpoint node via the network. The congestion controller can be conf ...

Price-based Controller for Quality-Fair HTTP Adaptive Streaming

Pascal Frossard, Laura Toni, Stefano D'Aronco

HTTP adaptive streaming (HAS) has become the universal technology for video streaming over the Internet. Many HAS system designs aim at sharing the network bandwidth in a rate-fair manner. However, rate fairness is in general not equivalent to quality fair ...
