Abstract
This project aims to study the key
enabling technologies and the
architecture planning issues for the
Dual-Mode Hybrid Broadband Access,
using ADSL and WLAN in parallel as
two complementary access technologies.
Under this Dual-Mode Hybrid access
scenario, each end user’s router or host
computer will be provided with both
ADSL access as well as Outdoor/Public
WLAN access so that the total access
bandwidth can be boosted, while the
service and applications over this
network can be provisioned
dynamically over different network
interfaces. The quality of service for
each specific application stream shall
be maintained to meet its own traffic
characteristics and the traffic load of between the WLAN link and ADSL link
can be balanced intelligently. In order
to boost the instantaneous access
bandwidth, in the first year, we have
completed the preliminary studies and
proposed designs for the following key
technologies and issues:
a. A smart application level load
balancing routing mechanism for the
router and the middleware for the host
computer directly on the Dual-Mode
Hybrid Broadband Access
b. An efficient network status
monitoring mechanism and a smart
classification mechanism
c. The Network Planning model and
optimization issues for the Dual-Mode
Hybrid Broadband Access architecture
We plan not only to propose
novel network monitoring mechanism,
classification algorithm, the Dual-Mode
Hybrid Access routing engine, the
middleware, and its detailed network
architecture, an integration test beds
will be established.
