Pattern Matching (PM) is a key building block for many emerging network applications. Modern multicore platforms are becoming performance competitive with traditional hardware solutions, which are expensive and hard to adapt to the rapid diversification of Internet applications. However, due to uneven network flow sizes and the need to retain packet order within each flow, traditional parallel processing...
The traditional client-server architecture widely adopted on the Internet is not adequate to meet the increasing user loads and bandwidth demands in live streaming systems especially for multimedia content delivery. Peer-to-peer P2P) overlay networks provide excellent system scalability and high resource utilization, which make it an attractive solution to this problem. This paper considers a hybrid...
Recently network virtualization is considered as a powerful way to overcome the current ossification of Internet, and is viewed as the keystone of the next-generation network architecture. In network virtualization, virtual network (VN) embedding problem, which assigns virtual nodes and links to physical network, plays an important role. Due to the scarcity of physical resource, efficient and effective...
Load balance is an important problem of cluster. The core of cluster task distribution is the load balance algorithm. LVS load balance technology is introduced briefly, the known load balancing algorithms and their merits and demerits are discussed in this paper; A Residual Load Rate based the combination of static and dynamic balance strategy is proposed after analyzing static balance technology...
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...
Cloud platforms enable enterprises to lease computing power in the form of virtual machines. An important problem for such enterprise users is to understand how many and what kinds of virtual machines will be needed from clouds. We formulate demand for computing power and other resources as a resource allocation problem with multiplicity, where computations that have to be performed concurrently are...
The future Internet is driven by applications that require simultaneous access to multiple heterogeneous IT resources interconnected by high-speed optical network. Current research on network and IT resource co-allocation address advanced reservations in which each resource-type is optimised independently. However, emerging applications demand a resource co-allocation model that views and optimizes...
MMOG usually adopts multiple servers cluster to do with avatars' request. But its tussle and walk makes servers over-loaded. This paper presents a dynamic load balancing algorithm between local and global algorithms, which is called Finding Less-loaded Server algorithm, and has a detailed analysis of the algorithm. It is useful for over-loaded servers to find less-loaded ones, and keeps game's real-time...
As Grid technologies evolve quickly on Internet, research related to resource scheduling faces new opportunities and challenges. These new technologies, ideas and approaches provide a new environment for researching and developing the economy-based resource scheduling system. Aiming at the hierarchical Grid model, following utility optimization thinking, while an universal flexible utility function...
The hybrid application layer multicast (ALM) has been shown its efficiency by leveraging the conventionally main structures of application layer multicast, tree-based and mesh-based. However, how to select the proper node to construct the overlay and how to establish the connection between any two nodes are still unsolved. Therefore, this paper is to design a novel construction algorithm for the hybrid...
Traditional intrusion detection equipments hardly satisfy the application requirements as the data rates of modern networks rise. Adaptive load balancing algorithm (Adaptive HRW Hashing) may make attacks undetected due to flow remapping. So, the load balancing algorithms in network intrusion detection system (NIDS) are firstly studied, and then a load balancing algorithm based on Bloom Filters is...
Information infrastructures such as Internet have been a great success in the past few decades and gradually become mature, diversified user requirements continue to grow at a fabulous speed. Multiplex services on secure networked environments are now deemed as an application licensed to customers for use as a trustworthy service on demand. The flexible reconfiguration network is the next step to...
Load balancing is critical to the performance of parallel processing systems. It is more difficult for network systems such as NIDS and Web Servers, because they must preserve flow order. But traditional flow-based load balancing schemes of network parallel processing systems, such as LLF, cost much resource and introduce lots of communication overhead. With the rapid popularization of multi-core...
Distributed Virtual Environment (DVE) has attracted much attentions in recent years due to the rapid advances in the areas of E-learning, Internet gaming, human-computer interfaces, and etc. Meanwhile, in recent years, the emergence of Service Oriented Architecture (SOA) provides a more flexible and inter-operable framework for building more advanced DVE based applications. In such a background, service...
Nowadays, due to the advantage of technology and the Internet popularization, Peer-to-Peer (P2P) computing technology has been gradually becoming the mainstream on the distributed system applications. However, the main purpose of P2P computing technology is to process the large-scale task through the distributed system computer cooperatively. Therefore, how to efficiently assign tasks to every nodes...
We study the online stochastic bipartite matching problem, in a form motivated by display ad allocation on the Internet. In the online, but adversarial case, the celebrated result of Karp, Vazirani and Vazirani gives an approximation ratio of 1- 1/e ?? 0.632, a very familiar bound that holds for many online problems; further, the bound is tight in this case. In the online, stochastic case when nodes...
The existing load balancing technology in the content distribution network (CDN) only emphasizes even load distribution among servers, and it does not make the best of network topological information and the historical information of file accessed, so user request can not get timely response. To solve the above problem, this paper presents a load balancing a algorithm based on the Distributed binning...
The usage of network resources by content providers is commonly governed by service level agreements (SLA) between the content provider and the network service provider. Resource usage exceeding the limits specified in the SLA incurs the content provider additional charges, usually at a higher cost. Hence, the content provider's goal is to provision adequate resources in the SLA based on forecasts...
A generic and self-managing service hosting infrastructure, provides a means to offer a large variety of services to users across the Internet. Such an infrastructure provides mechanisms to automatically allocate resources to services, discover the location of these services, and route client requests to a suitable service instance. In this paper we propose a dynamic and latency-aware algorithm for...
Load balancing is an effective technique that keep network from congestion when link is over load or link failures occur. The performance of balancing system is determined by granularity of load splitting. The finer the granularity is, the better performance can be attained. But splitting schemes must make a tradeoff between slicing granularity and packets reordering. Packet-level granularity can...
