Research projects

Planet-wide content distribution. Scalable solutions for global content management, traffic mapping and load balancing in large-scale Content Distribution Networks (CDNs).

Latency-sensitive multicast. Minimum-delay event notification to large (dynamic) groups of receivers with significantly better latency and scalability over existing techniques.

pCache. A high performance and transparent proxy cache server for P2P traffic --BitTorrent and others-- relieving their substantial burden for ISPs.

svcAuth. A light-weight authentication scheme for H.264 (SVC and AVC) video streams that enables to digitally sign a stream once and then verify any possible substreams extracted from it. Released as an open source Java library.

Peer-assisted streaming of videos with scalable (flexible) encoding. Approximation algorithms and analytical frameworks for streaming resource allocation and forecasting.
