In distributed computing frameworks like MapReduce, Spark, and Dyrad, a coflow is set of flows transferring data between two stages job. The job cannot start its next stage unless all in the finish. To improve execution performance such job, it crucial to reduce completion time coflow, as can contribute more than 50 percent time. While several schedulers have been proposed, we observe that rout...

We investigate source–controlled resource allocation for orthogonal transmission of heterogenous sources over a multiuser system. The system resources bandwidth and power are shared among all users in such a way that the average distortion for all users is minimised. Especially in mobile communications, the allocation of resources among users with different applications is a challenging task. T...

Efficient dynamic resource provisioning algorithms are necessary to the development and automation of Quality of Service (QoS) networks. The main goal of these algorithms is to offer services that satisfy the QoS requirements of individual users while guaranteeing at the same time an efficient utilization of network resources. In this paper we introduce a new service model that provides per-flo...

Bandwidth Allocation Models (BAMs) configure and handle resource allocation (bandwidth, LSPs, fibre) in networks in general (IP/MPLS/DS-TE, optical domain, other). BAMs currently available for IP/MPLS/DS-TE networks (MAM, RDM, G-RDM and AllocTC-Sharing) basically define resource restrictions (bandwidth) by “class” (traffic class, application ś class, user ś class or other grouping criteria) and...

We consider a single node which multiplexes a large number of traffic sources. We restrict ourselves to consideration of aggregates of i.i.d. flows that can modelled using effective bandwidth results. We are concerned with the amount of buffer and bandwidth that should be allocated to this aggregate, under a maximum overflow probability constraint. Unlike previous approaches which assume that t...

IEEE 802.16 Wireless Network technology is a hot research issue in recent years. It provides wider coverage of radio and higher speed wireless access, and Quality-of-Service plays an important part in the standard. For mobile multihop wireless network, IEEE 802.16j/MR network not only can supply large area wireless deployment, but also can provide high quality network service to mobile users. A...

The distributed queue dual bus (DQDB) protocol, the media access protocol of the IEEE 802.6 standard for metropolitan area networks, does not fully take advantage of the capabilities of a dual bus architecture. Although a fair bandwidth distribution among the stations is guaranteed when using the socalled bandwidth balancing mechanism, the protocol requires a considerable amount of time to adju...
