Data center networks continually seek higher network performance to meet the ever increasing application demand. Recently, researchers are exploring the method to enhance the data center network performance by intelligent caching and increasing the access points for hot data chunks. Motivated by this, we come up with a simple yet useful caching mechanism for generic data centers, i.e., a server caches...
This paper presents an analytical model for analyzing the performance of the TDMA-based distributed reservation protocol for wireless multi-hop ad hoc networks. A novel three-way handshake process is presented which considers the hold-off and competition process before the transmission of scheduling messages. An explicit expression of expectation of the average delay of the three-way handshake process...
Today's interdomain routing is traffic agnostic when determining the single, best forwarding path. Naturally, as it does not adapt to congestion, the path chosen is not always optimal. In this paper, we focus on designing a multi-path interdomain forwarding (MIFO) mechanism, where AS border routers adaptively forward outbound traffic from a congested default path to an alternative path, without touching...
The flexibility of Cloud computing allows elastic services to adapt to changes in workload patterns in order to achieve desired Service Level Objectives (SLOs) at a reduced cost. Typically, the service adapts to changes in workload by adding or removing service instances (VMs), which for stateful services will require moving data among instances. The SLOs of a distributed Cloud-based service are sensitive...
Community Clouds, usually built upon community networks, operate in a more disperse environment compared to a data center Cloud, with lower capacity and less reliable servers separated by a more heterogeneous and less predictable network interconnection. These differences raise challenges when deploying Cloud applications in a community Cloud. Open Stack Swift is an open source distributed storage...
As inter-domain routing on today's Internet does not and basically cannot consider traffic load when determining best traffic forwarding paths, it is not always optimal for a router to forward packets along its default path, especially when the router's default output port incurs a long queuing delay. In this paper, we design a new approach called TED in which border routers of autonomous systems...
In this paper, we propose an improved utility-based radio resource allocation algorithm in orthogonal frequency division multiple access (OFDMA) wireless networks. The queue state information (QSI), channel state information (CSI), QoS requirements and transmitted packets are synthetically considered in the utility function, thus it can meet the needs of networks with multi-service better. Based on...
Network information monitoring technology (NIMT) is a key technology to the next generation of network defense system. The existed NIMTs mostly do not have a dynamic warning and controlling function, neither support IPv6. This paper provides a scalable network dynamic monitoring and warning system. It forms an associated dynamic security defense system based on traffic analyse, intrusion detection...
High-speed network content security applications often offload signature matching to hardware. In such systems, the throughput of the overall system, rather than the hardware engine alone, is significant. The authors offload virus scanning in the ClamAV antivirus package to the BFAST* hardware engine. They find that the data-passing processes significantly degrade system throughput.
