About Me

I am a Ph.D student at the Dept. of Communication and Networking and my advisor is Prof. Jörg Ott. I mainly work in the area of multimedia and networks (for example: IPTV, over the top streaming [http], interactive peer-to-peer communication, telepresence) with emphasis on congestion control and rate-adaptation.

Currently writing up my doctoral thesis, see progress here (the page is written using Python, D3.js, Github and Parse APIs).

Congestion Control using FEC for Conversational Multimedia Communication; Nagy M., Singh V., Ott J., Eggert L., MMSys 2014, Singapore [PDF]

Special assignments:

  • Hack OpenWRT for flow monitoring.

Multipath RTP

Adding multipath features to RTP/RTCP requires protocol extensions. MPRTP also requires additional algorithms for load balancing and adaptive playout.

Congestion Control

Rate-control for conversational interactive real-time media in heterogeneous environments (for example: WLAN, 3G and high throughput-low latency networks).

View details »

HTTP Streaming

Interaction of congestion-control with CDN caching (media segment size, cache size). Also challenges with pre-buffering in 3G environments.
