Sentence examples for dba schemes from inspiring English sources

However, the existing Dynamic Bandwidth Allocation (DBA) schemes for EPONs only consider the upstream bandwidth requests.

DBA schemes call for adjustment only when the current estimate of the mean deviation of the quality characteristic from target jumps outside the action limits.

This paper considers DBA schemes under a general model framework, which includes nonstationary disturbances — possibly containing deterministic drifts — and delayed dynamics.

The algorithm is designed to efficiently and fairly distribute the amount of excess bandwidth based on a profit value derived from the excess bandwidth usage of each ONU, which resolves the problems of previously reported DBA schemes that are either unfair or inefficient.

For performance evaluation in terms of average delay, average queue size, loss rate and utilization, five DBA schemes are simulated, namely AP-Sort DBA, interleaved polling with adaptive cycle time (IPACT), dynamic bandwidth allocation with a modified grant table generation algorithm and fair-excess allocation (DBA2-FE), Sort-DBA and double phase polling algorithm (DPA).

Balancing fairness in bandwidth distribution with network efficiency is also the primary aim of the DBA scheme proposed in [38], which targets XG-PONs.

The authors also proposed a QoS-aware DBA scheme which can support bandwidth fairness at the VOB level and class of traffic fairness at the SS level.

Yang et al.[6] presented a converged network architecture based on the concept of virtual ONU-BS (VOB) and proposed a QoS-aware dynamic bandwidth allocation (DBA) scheme.

DBA scheme based on Load balance algorithm (LBA) and wavelength recycle mechanism (WRM) for multi-wavelength upstream transmission is proposed in this paper.

The proposed QoS-aware DBA scheme is operated in a hierarchical manner and therefore can support bandwidth fairness at the VOB level as well as class of traffic fairness at the SS level.

CRDtHoweverthequal to 0.4 for the purpose of simulations.
