Datacenter is usually shared among different applications and tenants as cloud service infrastructure. Traditional network allocation reserves the bandwidth but the traffic behavior is unpredictable. InfiniBand (IB) is more widely applied in the construction of datacenter cluster and attracts more interest from the academic field as well. In this paper, we first propose an IB bandwidth allocati...

-Cloud computing is a new development emerging in IT environment with vast requirements of infrastructure and resources. Band width allocation and Load balancing is an important aspect of cloud computing environment. Bandwidth allocation plays a most important part in sharing the resources to the data center networks. In this paper we propose a new bandwidth allocation scheme based on unused ba...

In this research, we focused on fair bandwidth allocation on the Internet. The Internet provides communication services based on exchanged packets. The bandwidth available for each customer is often fluctuated. Fair bandwidth allocation is an important issue for ISPs to gain customer satisfaction. Static bandwidth allocation allows an exclusive bandwidth for specific traffic. Although it gives ...

In this paper, we propose a bidirectional bandwidth-allocation mechanism to improve TCP performance in the IEEE 802.16 WiMAX networks. According to the IEEE 802.16 standard, when serving a downlink TCP flow, the transmission of the uplink ACK, which is performed over a separate unidirectional connection, incurs additional bandwidthrequest/allocation delay. Thus, it increases the round trip time...

An available bit rate (ABR) service allows applications to access a time-varying network capacity. In a basic ABR service, the available network capacity is divided \fairly" amongst active connections, without regard to the utility that each application derives from the bandwidth allocation. The goal of this paper is to improve both the global and individual utility obtained by applications usi...

We consider the problem of bandwidth allocation in a substrate network as an optimization problem for the aggregate utility of multiple applications with diverse requirements and describe a simulation scheme for dynamically adaptive bandwidth allocation protocols. The proposed simulation model based on Coloured Petri Nets (CPN) is realized using CPN Tools. Keywords—Bandwidth Allocation Problem,...
