چکیده

We investigate reliable multicast communication over satellite networks. We compare a scenario where receivers can use a feedback channel to signal loss to a scenario where no feedback channel is available. We show that the introduction of a feedback channel is the key to allow for bandwidth-e cient, robust, and fully reliable multicast communication via satellite.

Scalable IP Multicast Sender Access Control for Bi-directional Trees

Bi-directional shared tree is an efficient routing scheme for interactive multicast applications with multiple sources. Given the open-group IP multicast service model, it is important to perform sender access control so as to prevent group members from receiving irrelevant data, and also protect the multicast tree from various Denial-of-Service (DoS) attacks. Compared with source specific tree...

Effects of Multi-directionality on Pedestrian Flow Characteristics

In design and analysis, standard references assume the pedestrian flow as unidirectional. In reality however, pedestrian flow is usually bi-directional. The main question pursued in this paper is that whether the main characteristics of pedestrian flow the same under uni- and bi-directional conditions. In order to achieve this goal, effect of bi-directional stream is inv...

Scalable sender access control for bi-directional multicast routing

Bi-directional shared tree is an efficient routing scheme for interactive multicast applications with multiple sources. Given the open-group IP multicast service model, it is important to support sender access control in order to prevent group members from receiving irrelevant data, and also to protect the multicast tree from Denial-of-Service (DoS) attacks. Compared with source specific and un...

Scalable Adaptive Group Communication on Bi-directional Shared Prefix Trees

E cient group communication within the Internet has been implemented by multicast. Unfortunately, its global deployment is missing. Nevertheless, emerging and progressively establishing popular applications, like IPTV or large-scale social video chats, require an economical data distribution throughout the Internet. To overcome the limitations of multicast deployment, we introduce and analyze B...
