A network coding approach to the shipper detection problem
Christina Fragouli, Lorenzo Keller, Abdulkadir Karaagaç
This paper experimentally studies the reliability and delay of flooding based multicast protocols for a sniper detection application. In particular using an emulator it studies under which conditions protocols based on network coding deliver performance im ...
2011On the Capacity of Noncoherent Network Coding
Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani
We consider the problem of multicasting information from a source to a set of receivers over a network where intermediate network nodes perform randomized linear network coding operations on the source packets. We propose a channel model for the noncoheren ...
Institute of Electrical and Electronics Engineers2011Achieving high-throughput State Machine Replication in multi-core systems
André Schiper, Nuno Filipe de Sousa Santos
State machine replication is becoming an increasingly popular technique among online services to ensure fault-tolerance using commodity hardware. This has led to a renewed interest in its throughput, as these services have typically a large number of users ...
2011Multi-Graph Regularization For Efficient Delivery Of User Generated Content In Online Social Networks
We present a methodology for enhancing the delivery of user-generated content in online social networks. To this end, we first regularize the social graph via node capacity and link cost information associated with the underlying data network. We then desi ...
2011Algebraic techniques for deterministic networks
Christina Fragouli, Javad Ebrahimi Boroojeni
We here summarize some recent advances in the study of linear deterministic networks, recently proposed as approximations for wireless channels. This work started by extending the algebraic framework developed for multicasting over graphs in [1] to include ...
2010NC Node Selection Game in Collaborative Streaming Systems
Pascal Frossard, Nikolaos Thomos, Eymen Kurdoglu
Network coding has been recently proposed as an efficient method to improve throughput, minimize delays and remove the need for reconciliation between network nodes in distributed streaming systems. It permits to take advantage of the path and node diversi ...
2010On Source Transmission over Deterministic Relay Networks
Lossless transmission of a set of correlated sources over a deterministic relay network is considered for two traffic requirements. In distributed multicast, the set of sources are to be delivered to a set of destinations. The source exchange requires all ...
2010Bandwidth Adaptation in Streaming Overlays
Dejan Kostic, Nedeljko Vasic, Simon Schubert
A major challenge for real-time streaming overlays is to distribute high bit-rate streams with uninterrupted playback. Hosts usually have sufficient inbound bandwidth to support streaming, but due to the prevalence of asymmetric links in broadband networks ...
2010Scalable Multicasting in One-Pump Parametric Amplifier
We report the experimental demonstration of all-optical
wavelength multicasting of OC-768 (40 Gbps) channel using
a single-pass, pump modulated parametric amplifier. The performances
of 1-to-20 and 1-to-40 multicasting with excellent signal fidelity
we ...
Institute of Electrical and Electronics Engineers2009Multicast Parametric Sampling of 320 Gb/s Return-to-Zero Signal
Technology for simultaneous demultiplexing of subrate tributaries is described and applied to 320-Gb/s return-tozero input. The parametric architecture is scalable with respect to processed input rate and relies on cascaded all-optical multicasting and sub ...
