“…Since multicast is a technology of choice for VEs, some of the network QoS requirements to be considered in supporting large-scale systems are enumerated in the following taxonomy [13]. However, the taxonomy does not determine how the QoS may be ensured by the Internet.…”

The field of shared virtual environments, which also encompasses online games and social 3D environments, has a system landscape consisting of multiple solutions that share great functional overlap. However, there is little system interoperability between the different solutions. A shared virtual environment has an associated problem domain that is highly complex raising difficult challenges to the development process, starting with the architectural design of the underlying system. This paper has two main contributions. The first contribution is a broad domain analysis of shared virtual environments, which enables developers to have a better understanding of the whole rather than the part(s). The second contribution is a reference domain model for discussing and describing solutions - the Analysis Domain Model.

“…In general, DVEs require high bandwidth to support multiple users and multimedia-rich VE content. The multiuser support leads to multipoint communication/distribution schemes [23]. As for VE content, it usually incorporates not only static and/or animated 3-D graphics primitives and models [24], but also other (multi)media types, such as images, audio, and video.…”

A framework for multi-user distributed virtual environments (DVEs) has been proposed. The proposed framework, incorporating two models (the functional model and the interconnection model), attempts to represent the common functionality, communication issues and requirements found in multi-user DVEs. The functional model concentrates on the DVE's functionality, while the interconnection model concentrates on how the components are interconnected to realize the required functionality. The models have been specified using the Unified Modeling Language (UML). An experimental case study demonstrates the applicability and generality of the proposed approach.

“…Clearly, message confidentiality is a very important issue for multicasting. 10,11,12 Cryptographic algorithms are often employed to secure multicast transmissions, where multicast packets are encrypted with cryptosystems. Only legitimate group members with the secret key can acquire the communication contents.…”

Scalable and lightweight key distribution for secure group communications

Securing group communications in dynamic and large-scale groups is more complex than securing one-to-one communications due to the inherent scalability issue of group key management. In particular, cost for key establishment and key renewing is usually relevant to the group size and subsequently becomes a performance bottleneck in achieving scalability. To address this problem, this paper proposes a new approach that features decoupling of group size and computation cost for group key management. By using a hierarchical key distribution architecture and load sharing, the load of key management can be shared by a cluster of third parties without revealing group messages to them. The proposed scheme provides better scalability because the cost for key management of each component is independent of the group size. Specifically, our scheme incurs constant computation and communication overheads for key renewing. In this paper, we present the detailed design of the proposed scheme and performance comparisons with other schemes. Briefly, our scheme provides better scalability than existing group key distribution approaches.
