It is widely believed that IP over optical networks will be a major component of the next
generation Internet However, it is not efficient to map a single multicast IP flow into one light …

The popularity of broadband streaming applications requires communication networks to
support high-performance multicasting at the optical layer. Suffering from transmission …

It is widely believed that IPTV will be one of the major applications in future IP networks and
that IP over optical networks will be a major component of the next generation Internet …

In this paper, we study the problem of multicast flow aggregation combined with light-tree
establishment in optical networks. We first give the network model with a tri-partite …

In this paper, we address the dynamic multicast flow aggregation problem and propose a
novel graph model with different aggregation policies. We first give the network model with …

The impact of IP over optical two-layer multicasting on the performance of channel zap**
is discussed through two simple experiments and evaluated by an large scale concurrent …

TV distribution is changing rapidly as traditional analog systems are replaced by
theirdigitized counterparts, which are more interactive and use bandwidth more efficiently …

To support large-scale IP-TV signal delivering, a new multicast-IP over light-tree network
model was proposed in W. Sun et al. In this paper, we study the problem of topology …

In this paper, we study the problem of multicast flow aggregation with the objective of
minimizing the total number of trees. Each established tree can choose a line rate from …

Existing multicast models have taken traffic concentration, source-end delay, delay jitter into
consideration, while some dynamic application like digital TV delivery poses a new …
