Title:
Analysis and characterization of IPTV user behavior
Type:
conference paper
Abstract:
Today, due to the fast development of Internet Protocol
TV (IPTV), which is the combination of IP technology and
two-way broadband networks, the telecom industry is undergoing
fundamental changes. Network operators and service providers
around the world are making significant investments in order
to deliver digital video content to their subscribers. Video puts
very high demands on the network and utilizes a large fraction
of the available bandwidth. Consequently, it is important to
understand the technical demands that IPTV requires of the
network infrastructure as well as user behavior and network
traffic patterns to further optimize network operation.
The purpose of this paper is to characterize IPTV traffic
and study end user behavior by analyzing and modeling IPTV
traffic collected from a Swedish municipal network. The focus
of the measurements was put on Internet Group Management
Protocol (IGMP) packets. Apart from the measurement results
and analysis, the paper provides background information about
the technologies and issues of IPTV. IP multicast which is used for
transferring Live TV content is based on the concept of a group.
IGMP is used to manage the membership of multicast groups.
Based on this information, traffic parameters for analysis were
chosen and measured.
