We present a design of an OpenFlow controller handling IP multicast and a method to switch
a multicast tree to the other with little packet loss. Reducing packet loss during …

We propose a multicast tree management method in an OpenFlow controller that handles
both fast failure recovery and dynamic multicast group membership changes. Multicast …

WiFi-based localization is a promising candidate of indoor localization. In this paper, we
present a distributed localization system using a WiFi ad-hoc wireless positioning network …

Service providers are currently seeking to offer high-quality IP video service on single
broadband IP network infrastructures, including ADSL and passive optical networks (PON) …

We propose an IP broadcasting system architecture using passive optical networks (PON)
utilizing the optical broadcast links of a PON with a downstream bandwidth allocation …

A dimensioning process of Gigabit Passive Optical Network (GPON) involves the selection of
a split ratio that determines the allocated bandwidth per subscriber sharing a single passive …

According to deployment of broadband access networks like FTTH (Fiber-To-The-Home),
many Internet Service Providers in Japan start providing video broadcasting services via IP …

This paper presents a renovative priority queuing algorithm for jitter-sensitive MPEG-2
Transport Stream distribution on home network. Upon the dissemination of broadband …

In this paper, we propose design and implementation of a practical end-to-end system which
implements multi-channel digital television (DTV) multicasting to the home over broadband …

Internet protocol (IP) is emerging as a ubiquitous protocol for communications and
applications. IP-based services aims to provide consumers anytime-anywhere access to …
