HSRM: a hierarchical scalable reliable multicast model for conferencing control over Internet
- Trang 75-80
A number of reliable multicast (RM) protocols have been proposed previously.
However, when used in conferencing control over the Internet, they are all faced
with challenges of poor scalability and robustness, or too much redundant
packets and abuse of network bandwidth, especially with the growth of group size
and scope. We present a new RM protocol named HSRM (hierarchical scalable
reliable mult...

Analysis by queuing model of multi-threshold mechanism in ATM switches
- Trang 147-151
In this paper, we present a queuing model for a congestion control mechanism in
ATM (asynchronous transfer mode) switches for ABR (available bit rate) services.
ABR services are designed to support applications that are loss sensitive but
tolerant to delay. ABR sources dynamically adjust their transmission rates in
response to congestion feedback from the network, and according to a congestion
con...

Applications of liquid crystal spatial light modulators in optical communications
- Trang 239-242
Advances in liquid crystal (LC) materials and VLSI technology have enabled the
development of multi-phase spatial light modulators (SLM) that can perform
high-resolution, dynamic optical beam positioning as well as temporal and
spatial beam shaping in the 1550 nm optical communication window. These
attractive features can effectively be used to achieve optical switching,
optical spectral equalizat...

Performance optimization in GSM networks through dynamic power control
- Trang 197-201
This paper deals with the detailed analytical overview of performance
optimization through dynamic power control in GSM Networks. The strategies for
power control as applicable for mobile stations and base stations have been
discussed. Concept of performance optimization diagram as applicable to live GSM
and GPRS networks has been presented from quality, received level and Handovers
point of view....

A design of subject model for Web-based education system
- 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...

Image capture using integrated 3D SoftChip technology
- Trang 19-23
Mobile multimedia communication has rapidly become a significant area of
research and development. The processing requirements for the capture,
conversion, compression, decompression, enhancement, display, etc. of high
quality multimedia content places heavy demands even on current ULSI (ultra
large scale integration) systems, particularly for mobile applications where
area and power are primary c...

A genetic algorithm for the degree-constrained multicasting problem
- Trang 315-319
In communication networks, the degree-constrained multicasting problem is of
great importance, which can be formulated as finding a minimal cost tree in the
presence of constraints on the copying ability of the individual switch nodes in
the networks. Up to now, there are few efficient algorithms for solving this
problem because of its NP-hard complexity. A new approach for solving this
degree-con...

The Dynamic User-oriented QoS Specification and Mapping for multimedia Differentiation Services
- Trang 365-369
In this paper, we proposed the Dynamic User-oriented QoS Framework (DUQF), which
provides effective adaptation control schemes for dynamic QoS specification and
mapping based on the combination of DiffServ and IntServ network architecture. A
DUQF network consists of a DiffServ WAN and lots of attached IntServ LAN that
connect to each other via a RSVP-aware router and a differentiation edge router,...

A method of designing a path restoration scheme for MPLS based network
- Trang 218-222
We present the design of a fault management scheme for an MPLS network. We use a
backup path restoration scheme and a dynamic restoration scheme which preassigns
an alternative path for the active transit path and also assigns a dynamic
alternate path for a link failure to avoid loss. This proposed method achieves
very high throughput as compared to existing methods. It is also suitable for
high s...
