An augmented chained fault-tolerant ATM switch
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612) - - Trang 397-400
A new fault-tolerant ATM switch architecture based on multistage interconnection network (MIN) was proposed. Multiple paths between each input-output pair of the network are accomplished by connecting together switching elements within the same stage. Besides that, 2/sup n/2/spl times/2 switching element were distributed between stage n to n+1 in MIN to increase the paths for each input-output pai...... hiện toàn bộ

A design of subject model for Web-based education system
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612) - - Trang 32-36
With the rapid growth of the Internet, its users and its applications, there has been considerable interest in Web-based education systems that facilitates distance education. We propose a subject model for a Web-based education system. The designed model uses a tree with multiple links. Each link weight has been derived from relationships among the concepts of the subject. The designed modular tr...... hiện toàn bộ

On fast computing bypass tunnel routes in MPLS-based local restoration
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612) - - Trang 234-238
We outline a mechanism for fast rerouting IP traffic around link failures using MPLS bypass tunnels. As the main component of this mechanism we propose a simplified single-pair incremental Dijkstra algorithm. We evaluate the algorithm and restoration mechanism performance when used in regular and random network topologies.

Investigation of JPEG2000 image transmission over next generation wireless networks
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612) - - Trang 71-74
The JPEG2000 standard was introduced for image compression. An analytical model is proposed for accurately predicting the resulting quality of JPEG2000-encoded images, if the bit-stream is transmitted over error-prone wireless channels. The estimation accuracy of the analytical model is validated by simulation results. Such an analytical model can be utilized by the base station to design efficien...... hiện toàn bộ

An unequal error protection using Reed-Solomon codes for real-time MPEG video stream
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612) - - Trang 254-258
Real-time MPEG video stream over a packet switching network is very sensitive to losses and errors. In the same way as the priority encoding transmission (PET) scheme, our purpose is to protect the different contents of the MPEG video stream according to their importance for video sample quality played out at the receiver side. However, our approach considers as very important the latency delay fo...... hiện toàn bộ

Performance analysis of queue scheduling mechanisms for EF PHB and AF PHB in DiffServ networks
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612) - - Trang 101-104
Expedited Forwarding Per-Hop Behavior (EF PHB) and Assured Forwarding Per-Hop Behavior (AF PHB) are the forwarding schemes operating in DiffServ networks. EF PHB is appropriate for flows with low delay, low latency and low jitter, and AF PHB provides guaranteed services with minimum bandwidth and buffer. The two PHB can be implemented by several queue scheduling mechanisms such as weighted round-r...... hiện toàn bộ

IGMP snooping: a VLAN-based multicast protocol
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612) - - Trang 335-340
This paper introduces a VLAN-based multicast protocol, which supports multicast communication over switch Ethernet. This protocol restricts the multicast traffic of an IP multicast group in a VLAN. It starts with a table including an IP multicast group and the corresponding VLAN. Then it can get the multicast session information to maintain the table by snooping the IGMP messages sent by hosts or ...... hiện toàn bộ
