Dynamic upstream bandwidth allocation over ethernet PONs
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005Ethernet passive optical networks (EPONs) are a low-cost:, high-speed solution to the bottleneck problem of the broadband access network. A critical issue of EPONs is the utility of a shared upstream channel among the local users, and thus, an efficient bandwidth allocation mechanism is required in order to facilitate statistical multiplexing among the

Dynamic fair bandwidth allocation for DiffServ classes
2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003The assured forwarding per hop behavior standardized by the IETF Differentiated Services working group provides four class-based differentiated IP services. In this service, however, unexpected service degradation may occur and differentiation among classes may be disordered if the network is designed to minimize over-provisioning or is under ...

Dynamic Bandwidth Allocation in IEEE 802.16
2006IEEE 802.16 has gained significant research attention because of its broadband wireless services over a large coverage area. Bandwidth allocation plays very important role at the link layer of IEEE 802.16. In this paper, by considering the Automatic Repeat reQuest (ARQ) scheme for an erroneous wireless channel, a dynamic bandwidth allocation algorithm ...

Prediction-based dynamic bandwidth allocation in WiFi
SPIE Proceedings, 2004We study the dynamic allocation of bandwidth for video traffic in wireless networks. Our approach consists of two stages. In the first stage, we apply the FARIMA (Fractional Autoregressive Integrated Moving Average) models to forecast traffic based on online traffic measurements.

Dynamic bandwidth allocation algorithm utilizing full band
Journal of Electronics (China), 2006A kind of Dynamic Full Bandwidth Utilized (DFBU) allocation algorithm is introduced. This algorithm allows a single link to use bandwidth far beyond its fair share bandwidth in a multi-service packet transporting system. Three important parameters as the bound on maximum and minimum bandwidth, the maximum packet delay and the minimum band width ...

Delay Sensitive EPON Dynamic Bandwidth Allocation Mechanism
2006 IEEE International Conference on Systems, Man and Cybernetics, 2006Ethernet passive optical network (EPON) is one of the potential solutions for the next generation access technology. Its economical equipment and maintenance costs are particularly attractive to telecommunication service providers. The EPON has a tree topology and the upstream bandwidth from optical network terminals to the optical line terminal is ...

Dynamic bandwidth allocation for multiple network connections
Proceedings of the 2014 ACM SIGCOMM workshop on Capacity sharing workshop, 2014Users expect a high level of application quality without annoying interruptions or delays when using applications in a communication network. This is particularly important in mobile environments where varying channel conditions, user mobility, and interference lead to a variation of the available network resources which ultimately affects application ...

Optimal dynamic bandwidth allocation for complex networks
Physica A: Statistical Mechanics and its Applications, 2013Abstract Traffic capacity of one network strongly depends on the link’s bandwidth allocation strategy. In previous bandwidth allocation mechanisms, once one link’s bandwidth is allocated, it will be fixed throughout the overall traffic transmission process. However, the traffic load of every link changes from time to time.
