Fair Network Bandwidth Allocation in IaaS Datacenters via a Cooperative Game
Approach
Abstract:
With wide application of virtualization technology, tenants are able to access
isolated cloud services by renting the shared resources in Infrastructure-as-a-
Service (IaaS) datacenters. Unlike resources such as CPU and memory, datacenter
network, which relies on traditional transport-layer protocols, suffers unfairness
due to a lack of virtual machine (VM)-level bandwidth guarantees. In this paper,
we model the datacenter bandwidth allocation as a cooperative game, toward
VM-based fairness across the datacenter with two main objectives: 1) guarantee
bandwidth for VMs based on their base bandwidth requirements, and 2) share
residual bandwidth in proportion to the weights of VMs. Through a bargaining
game approach, we propose a bandwidth allocation algorithm, Falloc, to achieve
the asymmetric Nash bargaining solution (NBS) in datacenter networks, which
exactly meets our objectives. The cooperative structure of the algorithm is
exploited to develop an online algorithm for practical real-world implementation.
We validate Falloc with experiments under diverse scenarios and show that by
adapting to different network requirements of VMs, Falloc can achieve fairness
among VMs and balance the tradeoff between bandwidth guarantee and
proportional bandwidth sharing. Our large-scale trace-driven simulations verify
that Falloc achieves high utilization while maintaining fairness among VMs in
datacenters.

The document proposes a Covert Flows Confinement mechanism (CFCC) for virtual machine (VM) coalitions in cloud computing environments. CFCC uses a prioritized Chinese Wall model to control covert information flows between VMs based on assigned labels, allowing flows between similarly-labeled VMs but disallowing flows between VMs from different conflict of interest sets. The architecture features distributed mandatory access control for all VMs and centralized information exchange. Experiments show the performance overhead of CFCC is acceptable. Future work will add application-level flow control for VM coalitions.

Energy efficient virtual base station formation in optical-access-enabled clo...

ieeepondy

In recent years, the increasing traffic demand in radio access networks has led to significant growth in the number of base stations and energy consumption. This paper proposes forming virtual base stations in an optical-access-enabled Cloud-RAN to improve energy efficiency. A virtual base station is dynamically formed for each cell by assigning virtualized fronthaul links and baseband processing resources. An integer linear program is used to optimize the virtual base station formation. Simulation results show that the proposed virtual base station formation approach achieves significant energy savings compared to traditional radio access networks and Cloud-RAN without virtualization.

VPN service providers have traditionally kept their network topology private from IP-VPN customers, limiting interaction between them. This document proposes a Topology Abstraction (TA) service that provides controlled visibility of the service provider's network to VPNs. The TA service generates abstracted views of the network for each VPN accurately and fairly. Three decentralized schemes are developed to generate TAs with different performance characteristics, improving call performance for VPNs, fair resource sharing, and higher network utilization for the service provider. Simulation results validate the TA service concept and evaluate the proposed techniques over various network topologies.

Chorus is a new protocol that improves the efficiency and scalability of wireless broadcast using self-interference cancellation. It allows packet collisions at the MAC/PHY layers by effectively detecting and decoding overlapping packets carrying the same data. Chorus resolves collisions using symbol-level interference cancellation and combines the resolved symbols to restore packets. It also uses a cognitive sensing and scheduling MAC scheme. Evaluation shows Chorus has superior performance over CSMA/CA in scalability, reliability, delay, and various network scenarios.

FLEXIBLE VIRTUAL ROUTING FUNCTION DEPLOYMENT IN NFV-BASED NETWORK WITH MINIMU...

IJCNCJournal

In a conventional network, most network devices, such as routers, are dedicated devices that do not have much variation in capacity. In recent years, a new concept of Network Functions Virtualisation (NFV) has come into use. The intention is to implement a variety of network functions with software on general-purpose servers and this allows the network operator to select any capabilities and locations of network functions without any physical constraints. This paper focuses on the deployment of NFV-based routing functions which are one of critical virtual network functions, and present the algorithm of virtual routing function allocation that minimize the total network cost. In addition, this paper presents the useful allocation policy of virtual routing functions, based on an evaluation with a ladder-shaped network model. This policy takes the ratio of the cost of a routing function to that of a circuit and traffic distribution in the network into consideration. Furthermore, this paper shows that there are cases where the use of NFV-based routing functions makes it possible to reduce the total network cost dramatically, in comparison to a conventional network, in which it is not economically viable to distribute smallcapacity routing functions

Java capacity of hybrid wireless mesh networks with random a ps

Ecway Technologies

The document discusses the capacity of a hybrid wireless mesh network architecture that utilizes connections to randomly placed access points (APs) of wireless local area networks (WLANs). It presents that theoretical analysis shows the asymptotic capacity of such a three-tier hybrid network is affected by the number of mesh router cells connected to APs, the ratio of access link bandwidth to backbone link bandwidth, and traffic balance among mesh routers with AP access. The network architecture and results suggest hybrid wireless mesh networks can significantly improve capacity by taking advantage of widely deployed WLANs.

JungIn Jung

This document proposes EYWA, a virtual network architecture for cloud environments that aims to overcome scalability limitations of conventional architectures. EYWA uses virtual routers distributed across hypervisor hosts to provide high availability and load balancing for public networks without bottlenecks. It employs VxLAN to provide large private IP subnets for tenants by eliminating issues like VLAN limits and MAC flooding. Key to EYWA is an agent on each hypervisor that monitors virtual routers, caches ARP entries, and controls ARP packets according to rules to enable multiple virtual routers per tenant with a single IP address.

From IaaS to PaaS to Docker Networking to … Cloud Networking Scalability

DaoliCloud Ltd

This document discusses the scalability challenges of cloud networking and proposes a solution using Network Virtualization Infrastructure (NVI) technology. It reasons that NVI can provide scalable cloud networking by connecting independently orchestrated clouds, each with a modest physical scale, using network patching. This is presented as a solution to the lack of scalability in today's cloud networking practices, which are discussed and shown to involve non-virtualization and scale-up approaches that limit overall size.

Optimizing the placement of cloud data center in virtualized environment

IJECEIAES

In cloud mobile networks, precise assessment for the position of the virtualization powered cloud center would improve the capacity limit, latency and energy efficiency (EEf). This paper utilized the Monte Carlo oriented particle swarm optimization (PSO) and genetic algorithm (GA) to first, obtain the optimal number of virtual machines (VMs) that maximize the EEf of the mobile cloud center, second, optimize the position of the mobile data center. To fulfil such examination, a power evaluation framework is proposed to shape the power utilization of a virtualized server while hosting an amount of VMs. In addition, the total power consumption of the network is examined, including data center and radio units (RUs). This evaluation is based on linear modelling of the network parameters, such as resource blocks, number of VMs, transmitted and received powers, and overhead power consumption. Finally, the EEf is constrained to many quality of service (QoS) metrics, including number of resource blocks, total latency and minimum user's data rate.

This document discusses how VMware Infrastructure can leverage Fibre Channel shared storage in a virtualized environment. It describes how NPIV enables individual VMs to have unique identifiers on the SAN fabric. This allows features like quality of service, monitoring, and security to be applied at the VM level rather than just the physical server. The document also provides examples of how NPIV and Brocade's adaptive networking capabilities can optimize performance and resource allocation for VMs during storage intensive tasks like backups.

Psdot 1 optimization of resource provisioning cost in cloud computing

ZTech Proje

The document discusses optimizing resource provisioning costs in cloud computing. It proposes an optimal cloud resource provisioning (OCRP) algorithm that formulates a stochastic programming model to minimize the total cost of reserving resources from cloud providers over multiple stages. The OCRP algorithm considers demand and price uncertainty and can be solved using different approaches like deterministic equivalent formulation or sample-average approximation. It allows cloud consumers to reduce resource provisioning costs compared to static pricing schemes.

Proposal of a Transparent Relay System with vNIC for Encrypted Overlay Networks

IJCSIS Research Publications

New generations of applications call for new demands that are totally different from previous uses of the Internet (e.g., cross-layer and network function virtualization), and the existing networks are not optimized for these new demands due to being overwhelmed by enormous numbers of external network protocols. Overlay network technologies aim to respond to such future network demands. Systems on overlay networks mitigate this protocol overload by exploiting the unlimited programmability of the overlay nodes comprising the system. This paper proposes an overlay node that works as a transparent proxy server and router for encrypted communication over overlay networks. This overlay node acts as a virtual switch over multiple layers of the OSI reference model (the datalink, network, transport, and session layers) using general-purpose components (a personal computer, physical network interface card, and virtual network interface card, developed using the C language). The ideas behind this proposal derive from the effectiveness of software-defined networks and network function virtualization. Finally, we examine the performance of the overlay node experimentally and suggest possible designs for future overlay networks.

1) The document discusses using ant colony optimization (ACO) algorithms to perform data mining across different clouds in a cloud data center. ACO algorithms are well-suited for this task as clouds can be logically partitioned. 2) It describes how ants would gather data from virtual machines in different clouds via a cloud management system. The ants would then use this data to discover useful patterns and classifications via probabilistic rules and pheromone updating. 3) Performing unsupervised mining with asynchronous, parallel agents avoids overloading the data center resources while it continues serving the clouds. The ACO approach is proposed as a light-weight solution for knowledge discovery in cloud data centers.

On the Optimal Allocation of VirtualResources in Cloud Compu.docx

hopeaustin33688

On the Optimal Allocation of Virtual Resources in Cloud Computing Networks Chrysa Papagianni, Aris Leivadeas, Symeon Papavassiliou, Vasilis Maglaris, Cristina Cervelló-Pastor, and �Alvaro Monje Abstract—Cloud computing builds upon advances on virtualization and distributed computing to support cost-efficient usage of computing resources, emphasizing on resource scalability and on demand services. Moving away from traditional data-center oriented models, distributed clouds extend over a loosely coupled federated substrate, offering enhanced communication and computational services to target end-users with quality of service (QoS) requirements, as dictated by the future Internet vision. Toward facilitating the efficient realization of such networked computing environments, computing and networking resources need to be jointly treated and optimized. This requires delivery of user-driven sets of virtual resources, dynamically allocated to actual substrate resources within networked clouds, creating the need to revisit resource mapping algorithms and tailor them to a composite virtual resource mapping problem. In this paper, toward providing a unified resource allocation framework for networked clouds, we first formulate the optimal networked cloud mapping problem as a mixed integer programming (MIP) problem, indicating objectives related to cost efficiency of the resource mapping procedure, while abiding by user requests for QoS-aware virtual resources. We subsequently propose a method for the efficient mapping of resource requests onto a shared substrate interconnecting various islands of computing resources, and adopt a heuristic methodology to address the problem. The efficiency of the proposed approach is illustrated in a simulation/emulation environment, that allows for a flexible, structured, and comparative performance evaluation. We conclude by outlining a proof-of- concept realization of our proposed schema, mounted over the European future Internet test-bed FEDERICA, a resource virtualization platform augmented with network and computing facilities. Index Terms—Federated infrastructures, resource allocation, resource mapping, virtualization, cloud computing, quality of service Ç 1 INTRODUCTION CLOUD computing promises reliable services deliveredthrough next generation data centers that are built on compute and storage virtualization technologies. According to Buyya et al., [1] “a cloud is a type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and the consumers” and accessible as a composable service via web 2.0 technologies. Therefore, with respect to cloud computing there exist the “as a service” definitions, which include software as a service (SaaS), infrastructure as a se.

Aashish Pande

The document proposes a Wireless Network Cloud (WNC) architecture that uses cloud computing technology to virtualize base stations. The WNC allows wireless access networks to operate in a cloud mode by separating hardware and software and providing resources in a centralized manner. It analyzes challenges like computational requirements for virtual base stations. Mobile cloud computing is also discussed, which moves computing and storage away from mobile devices into powerful cloud platforms accessed over wireless connections using thin clients. This approach extends battery life and improves data storage and processing capabilities for mobile users.

Service description in the nfv revolution trends, challenges and a way forward

ieeepondy

The telecommunications landscape is undergoing major changes with the introduction of SDN and NFV, which allow new ways of designing networks and deploying network functions. Accurately describing the services to be provided is crucial for integrating and ensuring interoperability between different NFV proposals. However, fully realizing the benefits of NFV presents unique challenges that the current service description proposals do not fully address. This paper reviews current NFV service description proposals, identifies key challenges, and proposes a straw man model for service and resource description that could guide future initiatives in addressing these challenges.

It derives a closed-form upper bound on system block error rate via union bound analysis. Then, it proposes adaptive transmission schemes and practical power optimizations based on both block error rate and pair-wise error probability to reduce energy use at remote radio heads while meeting a predefined non-zero block error rate quality of service requirement.
