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,...
This paper targets at service provisioning and bandwidth allocation in single-service overlay multicast network by modeling it as a first-price monopoly auction. We propose a game theoretic pricing mechanism for determining the distribution of a typical multimedia content from an origin server, via the unicast links. By leveraging the rich theory of strategic mechanism design of microeconomics, we...
In this paper, the Multiprocessor Bandwidth Inheritance (M-BWI) protocol is presented, which constitutes an extension of the Bandwidth Inheritance (BWI) protocol to symmetric multiprocessor and multicore systems. Similarly to priority inheritance, M-BWI reduces priority inversion in reservation-based scheduling systems, it allows the coexistence of hard, soft and non-real-time tasks, it does not require...
BitTorrent(BT)-like P2P traffic which occupy main network bandwidth affect other normal network applications badly. This paper presents a triggered dynamic mechanism for BT-like P2P bandwidth management. According to the variety of utilization percentage of egress router input/output cache, this mechanism could estimate the potential network congestion and be triggered to control the BT-like P2P bandwidth...
The broadcast method is the most efficient approach to deliver a popular video for utilizing bandwidth. By combining the Fibonacci and staircase methods, this paper presents a hybrid broadcasting method with low buffer requirement to deliver a constant bitrate compressed video. The proposed method allows users with bandwidth of double of the consumption rate to download and watch the video without...
With the rapid advance of computer and network technology, more and more applications are deployed in the customer-side network. These applications require different quality of service (QoS), but have to share a few bandwidth limited Internet connections. Owing to the IP network's best-effort delivery mechanism, the QoS requirements are hard to be satisfied. There have been plenty of QoS solutions...
The increasingly popular online hosting systems are designed to provide versatile and convenient platforms for content hosting and sharing. To guarantee adequate levels of service quality while conserving prohibitive server costs, such systems are often designed to integrate peer bandwidth contributions with strategic server resource provisioning in a complementary and transparent manner. This paper...
Network bandwidth allocation is crucial for certain applications with quality of service (QoS) requirement such as multimedia in network storage system. And the iSCSI OSD storage system is a object-based system which is a novel network storage technology. In this paper associating with the character of the iSCSI OSD storage system, we propose the priority-based greed bandwidth allocation (PBGBA) algorithm...
P2P technology offers a promising scalable solution for video-on-demand (VOD) service. Recent studies have found that departure misses are the major cause of server load in P2P-based VOD. Inspired by this finding, this paper addresses the design of bandwidth allocation policy to decrease departure misses and thereby reduce server load further. We first formulate the minimum departure misses problem...
According to the problems of existing live media streaming system, a P2P-based live media streaming system is brought forward, each peer in the system is not only consumer of live streaming service, but also provider of live streaming service. It overcomes the server bottleneck of current existing systems when the user scale is large, and has the characteristic of low requirement of network bandwidth...
Currently, most research and educational backbone networks consist of 10 G-bps network and some hosts connect to this backbone with 10-Gbps. When the hosts try to transfer data with high speed, network often experiences congestion at the backbone due to a confliction with commodity traffic. In such situations, queue size at the bottleneck point has an impact on the throughput performance of TCP data...
Peer-to-peer SIP (P2PSIP) based server farm is proposed to provide distributed solution of multimedia applications. In this paper, we focus on the bandwidth requirements of both DHT and SIP packets from the perspective of a single server node in P2PSIP based server farm to quantitatively evaluate the overhead caused by distributed architecture. Furthermore, the efficiency of server node is also studied...
NAS and SAN have their own advantages respectively and they are two primary network storage systems nowadays. But they also have their own limitations and can't meet the demand of the high-speedly increasing network application. This paper presents a new network storage architecture made by integrating NAS and SAN in IP: the high performance storage network (HPSN). Firstly, with the help of the Global...
Multicast service of multimedia data messages are attractive network application. In conventional TCP/IP computer network, all functions of group membership management, routing and bandwidth reservation are required to be supported by all intermediate routers and availability of the multicast service is not always enough for network users. The overlay multicast is an expected solution where only logical...
Computer network is an important phenomenon for digital information world. Computer network having the various problem due to more demand such as congestion control security, reliability, scalability, fairness etc. Multicast service helps computer network to flow information from one end to another end. In this paper, we provide BDQP approach to minimize the congestion control. NS-2 result shows,...
In order to guarantee continuous delivery of video streaming over best-effort (BE) forwarding network, some quality-of-service (QoS) strategies such as RSVP and DiffServ must be used to improve the transmission performance. However, these methods are too difficult to be employed in practical applications since their technical complexity. In this paper, we design and implement an efficient local bandwidth...
Peer-to-Peer (P2P) file sharing applications use multiple TCP connections between peers to transfer data. The aggressiveness and robustness of P2P technology remarkably improve transfer efficiency and network bandwidth utilization. However, while the network bottleneck link is congested, P2P applications tend to unfairly steal bandwidth from other traditional Internet applications (Client/Server mode),...
We consider the general scenario where content hosted by the server comprises streams and each peer can subscribe one or more streams. Multiple multicast trees are built to deliver the streams to respective peers while exploiting the overlap of their interests for efficient and scalable delivery. We propose an optimization framework for allocating server bandwidth to minimize distortion across the...
In this paper, we present a method for providing quality of service using bandwidth limitation. In practical demonstration of the idea, we have used an algorithm for packet queuing, a technique applicable in a setup where the systems are connected to the Internet through a server and the server receives and distributes all the packets requested from the all the users in the network. The idea basically...
We present a new method for managing bandwidth which is allocated among several services. In implementation of the idea, we have used a queuing algorithm, a packet queuing technique applicable in a setup where the systems are connected to the Internet through a server (running our module) and the server receives all the packets requested from the all the services.
