Performance Analysis of AL-FEC for RTP-Based Streaming Video Traffic to Residential Users
Source: University of Glasgow
Real-time applications used by residential customers, such as streaming video and IPTV, are sensitive to packet losses, whether due to IP-layer congestion, or link-layer problems such as bit errors induced by impulse noise. To achieve acceptable user experience for these applications, numerous Application-Layer Forward Error Correction (AL-FEC) schemes have been proposed. The authors evaluate some of the FEC schemes developed as part of the OpenFEC project, using packet loss traces of IPTV0-like traffic measured on ADSL and Cable links.
