All over the
world, companies are struggling to offer effective distance
services (tele-services) with real-time interactivity and trying
to come-up with complete domain specific solutions (for example
for health and education) in order to reduce the gap between
live and distance activity.
information and communication technology can play a pivotal role
for the provision of tele-education and tele-health services to
remote and rural areas. Out of many issues to be addressed for
the realization of such tele-services, one of the issues is the
provision of a data communication service which supports
sustainable data rates, redundancy, and performance as per
requirement of the service.
There are multiple network interfaces available which can be
used (aggregated bandwidth) to realize real-time interactivity
for such applications.
proposes to develop a software based product to be used for
bandwidth aggregation as per required quality of the service (QoS).
It will develop a system that, using the available wireless and
wired network interfaces, provides a dynamically aggregated
bandwidth which can be used to offer services requiring
sustainable data rates, redundancy, and real time performance.
will develop (design, optimize, implement- a research activity),
and test a system (a software module- a development activity)
for optimal utilization of multiple network interfaces by
aggregating the available bandwidth to achieve the required
quality of service of the application. The overall system
comprises of multiple software components for effective handling
and modularization of proposed bandwidth aggregation.
activity will include the formulation of a multi-constraint
optimization of multi-service, multi-server scheduling algorithm
with constraints of end to end delay, minimized re-order &
buffering overhead. The optimization of the algorithm is planned
to be carried out through simulation in Matlab/Simulink. The
development portion includes the implementation of the optimized
algorithm (a software system) to perform tasks like aggregation
and flow state management, augmenting TCP/IP stack with new data
structures to accommodate services proposed in the system,
tunneling services, and capacity estimation. The developed
system will be deployed on a test bed and shall be tested for
real time live video and audio applications (distance services
with interactivity) for e-Health and distance learning with
interactivity. The test bed will be remotely located multi-media
equipped PCs with multiple network interfaces to be used to show
real-time interactive distance service.
The key benefits of this project are given below:
- It will
develop a robust, maintainable, extendable system with all
the standard documentations and open many opportunities for
ICT industries to develop their product suite for multiple
mode (networked) terminals (MMTs).
Bandwidth Aggregation Router for interactive distance
services will be developed.
system once developed will open numerous opportunities to
offer services based on interactive voice and video
connectivity for distance services such as interactive
e-Health services providers for Patients; interactive
distance learning service providers for students; and
agriculture service providers for farmers.
project will benefit all major sectors of industry including
telecom, e-government, and health-care. It will also benefit
remote branches of commercial banks.
