- MiniFrame SoftXpand
- After I posted on Ncomputing (see Ncomputing: Sharing the power of a single computer), MiniFrame's PR agency contacted me and asked that I take a look at SoftXpand. At first glance, it appeared that MiniFrame was walking down the same path that many others had taken, creating technology in the...

- Selecting the Best Spanning Tree in Metro Ethernet Networks Using Genetic Algorithm
- IEEE Spanning Tree Protocol STP is a layer-2 protocol which ensures a loop free topology in Metro Ethernet networks. It is based on Minimum Spanning Tree solution that involves determining the links which can join all the nodes of a network together such that the sum of the costs of...

- Load Balancing of the Direct Linear Multisplitting Method in a Grid Computing Environment
- Many scientific applications need to solve very large sparse linear systems in order to simulate phenomena close to reality. Grid computing is an answer to the growing demand of computational power but communication times are significant and the bandwidth is variable, therefore frequent synchronizations slow down performances. The use of...

- Load Balancing in Dynamic Structured P2P Systems
- This paper proposes an algorithm for load balancing in such heterogeneous, dynamic P2P systems. This simulation results show that in the face of rapid arrivals and departures of objects of widely varying load, this algorithm achieves load balancing for system utilizations as high as 90% while moving only about 8%...

- Online Client-Server Load Balancing Without Global Information
- A distributed online algorithm is considered for maximizing throughput in a network of clients and servers, modeled as a bipartite graph. Unlike most prior work on online load balancing, it do not assume centralized control and seek algorithms and lower bounds for decentralized algorithms in which each participant has only...

- Multicast Group Communication as a Base for a Load-Balancing Replicated Data Service
- This paper gives a rigorous account of an algorithm that provides sequentially consistent replicated data on top of the view synchronous group communication service previously specified by Fekete, Lynch and Shvartsman. The algorithm performs updates at all members of a majority view, but rotates the work of queries among the...

- Dynamic Load Balancing in WDM Networks
- This paper new load balancing techniques are proposed based on IP-like routing, where the forwarding mechanism is only driven by the destination address. The aim of this work is to consider the applicability of this approach in the context of optical networks. The proposed algorithm (RSNE - Reverse Subtree Neighborhood...

- Load Balancing by Domain Decomposition: The Bounded Neighbours Approach
- This paper presents a new domain decomposition approach whose main goal is the computation of a load balancing partition while reducing the overhead to compute such a partition. In the proposed approach, the number of neighbours of each sub-domain produced by the decomposition can be bounded by a user supplied...

- Stateless Load Balancing Over Multiple MPLS Paths
- The paper proposes a flow-independent approach to balance the load coming from several multimedia applications (i.e., IP Telephony) over multiple paths between a source and a destination. The proposed strategy exploits the advanced path-controlling and packet-forwarding features of the MPLS technology to set up the paths computed by the routing...

- Improving Packing Algorithms for Server Consolidation
- Minimizing the number of servers and preparing sufficient resources are contradictory requirements in server consolidation. These requirements can be formalized as a variant of the bin packing problem, which is known to be NP-hard. The least-loaded, a load-balancing algorithm, is applied to the problem and compared to the classical First-Fit...

- Joint MAC-Aware Routing and Load Balancing in Mesh Networks
- Past approaches to routing in mesh networks either do not account for the MAC-layer interactions between the links in a tractable manner, or are agnostic to load-balancing across gateways. The answer to these problems is MaLB (MAC-aware and Load Balanced routing algorithm), a greedy tractable, and distributed mesh routing algorithm....

- Robust Load Balancing
- This paper studies the problem of balancing the traffic load in a network by route selection. The traditional approach starts from a given traffic matrix. However, as the traffic matrix is seldom available, estimated traffic matrices have to be used. Thus, the solution of the load balancing algorithm is not...

- Dynamic Association for Load Balancing and Interference Avoidance in Multi-Cell Networks
- Next-generation cellular networks will provide higher cell capacity by adopting advanced physical layer techniques and broader bandwidth. Even in such a next-generation system, boundary users would suffer from low throughput due to severe Inter-Cell Interference ICI and unbalanced user distributions among cells, unless additional schemes to mitigate this problem are...

Using techniques from mechanism design theory a mechanism for fair load balancing is designed in heterogeneous distributed systems. It...
