Recently, Cloud computing has emerged as a new computing paradigm on the Internet. Cloud computing facilitates flexible and efficient computer resource management via virtualization technologies at anytime and from anywhere, so that users can add and/or delete IT resources. Users can set up and boot the required resources and they have to pay only for the required resources. However, they have to...
In order to enhance the performance of the concurrent access in the WebGIS, this paper proposes a solution of the Loading Balance which is based on Parameter Weighted Method. This solution considers the three technical factors on the WebGIS server in terms of processing capability, response time and service loading. By using the Comprehensive Parameter Weighted Method, we implement the solution of...
We develop a protocol through which multipath enabled IP routers collectively engage in dynamic traffic engineering, to optimize performance in concert with legacy TCP congestion control. We build on recent theory which shows a globally optimum resource allocation across the TCP/IP layers can be achieved through control of rates and multipath routing fractions following a consistent congestion signal...
With the deployment of more and more resilience-critical Internet applications, there is a rising demand for multi-homed network sites. This leads to the desire for simultaneously utilising all available access paths to improve application data throughput. This is commonly known as Concurrent Multipath Transfer (CMT); approaches for several Transport Layer protocols have been proposed. Combined with...
In this paper, we propose a load balancing scheme for heterogeneous multiple AS (Application Server) system in IMS (IP Multimedia Subsystem) network. In IMS network, S-CSCF (Serving Call Session Control Function) utilizes iFC(initial Filter Criterion) downloaded by HSS(Home Subscriber Server) and generates service trigger through the SIP message. To perform load balancing among multiple AS with different...
HSPA (High Speed Packet Access) technologies have become an attractive solution for broadband wireless Internet access. This article evaluates the quality of service experimented by one HSPA user in the presence of multiple terminals sharing the cell capacity. The study focuses on Web traffic and includes analytical and simulation results, providing a basis for dimensioning and admission control in...
In order to ensure the optimum allocation of resources, the collecting and aggregating information among management computers, power apparatus, communication devices, transmission lines and so on in electrical network will grow more and more important. In this paper, the management system enable exchange and readily use information securely and effectively between two or more networks, systems, devices,...
A new streaming media network-architecture based on the fusion of P2P and CDN is proposed in this paper. It uses P2P network as the backbone, selects nodes of high-performance, high-bandwidth, and stable online time as CDN edge servers, and provides non-P2P users with streaming media services under the schedule of the load-balancing servers. Since P2P has the inherent drawback of flow disorder, an...
Research and discussion on the Internets addressing and routing scalability problems has been for more than a decade. IP aware growing population, and learned needs in terms of site multi-homing, traffic engineering, non-aggregatable address allocations and policy based routing have resulted in the continuous alarming growth of the routing tables in the Default Free Zone (DFZ). Constraints posed by...
As an all-IP network provides not only services that have been traditionally provided on the Internet but also many other services, it has a dramatically higher risk than conventional networks that an occurrence of congestion in one service leads to congestion in other services. Unlike conventional networks, an all-IP network should provide not only bandwidth but also processing ability simultaneously...
BitTorrent (BT) is an extremely successful peer-to-peer (P2P) application providing efficient file sharing over the Internet. The ever-increasing traffic among the peers has also put unprecedented pressure to Internet Service Providers (ISPs). P2P locality has therefore been widely suggested, which explores finding local resources to optimize the cross-ISP/AS traffic. However, the ISPs would fail...
For the general scenario of data distribution from one to many, the paper indicates that Internet includes large number of NAT and firewall equipments. In order to distribute data to all clients, the paper proposes that the clients use Web Service to fetch data. Taking into account that using Web Service will consume much of server's resource, the system uses both TCP Socket (to push data) and Web...
With the rapid growth of both information and users, how to effectively improve the quality of network service becomes an urgent problem to be addressed. Load balancing is to overcome this problem in an effective way. At present it is mainly achieved by the load-balancing hardware and software, but there are also many problems, such as unscientific and inaccurate algorithm, imperfect and impractical...
China's networks and railways develop rapidly, which urgently requires mobile Internet access. However there exist challenges on network integration of access schemes, on network applications of the transition period, on high cost of all-coverage access, on high bit error rate, on frequent interruption, and on traffic explosion. The proposed multi-homing hierarchy DTN-based train mobile Internet access...
The following topics are dealt with: data center; Internet networking; location sensing; RFID; clouds; grids; data streaming; querying; IP networks; system security; data management; network security; sensor networks; fault tolerance; routing; social networks; resource allocation; network coding; P2P; and wireless networks.
Although significant efforts have been devoted in the literature to measurements of the Internet topology, little attention has been given to the qualification of routing deviations and multipath dynamics at the Autonomous System (AS) routing level. We observed Internet AS-level routes toward thousands of destinations for several weeks between 2009 and 2010 to have a better understanding of these...
In this paper, we propose a non-weighted load balanced fast local protection scheme for survivable IP networks. Unlike conventional shortest path based routing, we relax shortest path constraints in computing working and backup routes to achieve load balancing purposes. Once a failure occurs, those nodes adjacent to the failure point use their backup routing tables to achieve fast local failure recovery...
The following articles are dealt with: Network-based context-aware input method editor; Task scheduling in wireless sensor networks; FINLAN packet delivery proposal in a next generation Internet; Distributing service against BGP path inflation; UPnP extensions for public IPv4 sharing in IPv6 environment; No break of virtual network during live migration; Distributed simulation environment for the...
Structured P2P system doesn't consider the actual physical topology when building the logical overlay, which would cause a serious mismatching between logical overlay network and physical network and affect the routing performance of the system. An advanced algorithm of K-bucket updating strategy base on structured Kademlia system was proposed. Using Landmark Binning algorithm and RTT detection will...
Multihoming load balancing improves network performance and makes better use of network resource by leveraging the traffic among the access links in a multihomed network. Currently, no effective load balancing system is available to handle the inbound traffic in a multihomed stub network, where the traffic volume is unknown to the network and the route of the traffic is hard to control. In this paper,...
