Abstract Broadband access network is being regarded as one of the best
solutions for the next generation Internet. The Dynamic Resource
Allocation (DRA) algorithms play an important role in efficiently
allocating the resource in the network. Moreover, the Quality of
Service (QoS) is also necessary to support multi services. However,
many proposed DRA algorithms which support QoS are focus on cycle
process and still unable to solve the problem of system load and
packets delay which caused by resource reallocated. Therefore, this
paper proposes a QoS Constraint Dynamic Resource Allocation
algorithm (QCDRA). The QCDRA realizes the calculation of QoS
constraint and resource reallocated value, and quantifies the size
of resource allocation which satisfies the constraint conditions. We
conduct detailed simulation experiments under the environment of
various parameters and compared with other algorithms. Simulation
results show that our proposed algorithm can reduce the system load
and packets delay about 12\% and 8\% respectively, and improve the
system throughput about 5\%.
