Quality of Service and MPLS Methodologies
White Paper Applications such as Web access, email, and file transfer can typically withstand network delays, but delay-sensitive applications such as voice, video, and other real-time applications cannot. Faster links require faster memory/buffers or more... [18 Jul 2008]
PLDT, the Leading Telecommunications Provider in the Philippines, Selects Allied Telesis Advanced Gigabit Switches for the Layer 2 Aggregation Requirements of Its Next Generation Network
White Paper The challenge was to minimize delays for voice and real-time traffic to meet customer service level agreements and expectations. Philippine Long Distance Telephone Company (PLDT) started out as a POTS (plain old telephone service) provider. [18 Jul 2008]
The Problem of Upstream Traffic Synchronization in Passive Optical Networks
White Paper Because distance from central office to every network unit is different, if every unit will transmit in its own time slot, due to differences in propagation delays, data will collide in the point where fibers from different network units join... [18 Jul 2008]
Experiments With Adaptive QoS Management for Multimedia Applications in Heterogeneous Environments
White Paper Furthermore, these applications can suffer severe performance degradation under conditions of unpredictable delays and losses in the network, as is the case in the Internet today. The Internet is a dynamic network of heterogeneous transmission... [17 Jul 2008]
Measuring Bandwidth Signatures of Network Paths
White Paper Forecaster is practical since it does not assume any a priori knowledge about the measured path, does not make any simplifying assumptions about the nature of cross-traffic, does not assume the ability to capture accurate packet dispersions or... [11 Jul 2008]
Path Selection and Bandwidth Allocation in MPLS Networks
White Paper The optimization is based upon the minimization of a non-linear objective function which under light load simplifies to OSPF routing with link metrics equal to the link propagation delays. Multi-protocol Label Switching extends the IP destination... [11 Jul 2008]
Distributed Load Balancing in the Presence of Node Failure and Network Delays
White Paper This algorithm is able to handle the loss of some computational nodes, the connectivity of the network, and the variations in tasks and transfer delays. The distribution of computational load across available resources is referred to as the load... [10 Jul 2008]
Dynamic Load Balancing in Distributed Systems in the Presence of Delays: A Regeneration-Theory Approach
White Paper The approach considers the heterogeneity in the processing rates of the nodes as well as the randomness in the delays imposed by the communication medium. A regeneration-theory approach is undertaken to analytically characterize the average overall... [10 Jul 2008]
Load Balancing in Distributed Systems With Large Time Delays: Theory and Experiment
White Paper In distributed-computing environments with high communication delays and cost, limiting the number of balancing instants in scheduling algorithms results in an improved performance compared to the case where load balancing is executed continuously. [10 Jul 2008]
Construction Company Reduces Construction Delays by 50 Percent With Portal Solution
White Paper By automating its knowledge management and quality management processes Colpatria improved communications with employees and contractors and helped reduce design and construction delays. Constructora Colpatria (Colpatria), a leader in Colombia's... [10 Jul 2008]
Dynamical Discrete-Time Load Balancing in Distributed Systems in the Presence of Time Delays
White Paper The implementation of a load balancing policy on a continuous basis in a delay-limited distributed computing environment may not only drain the computational resources of each Computational Element (CE), but can also lead to an unnecessary... [10 Jul 2008]
The Effect of Time Delays on the Stability of Load Balancing Algorithms for Parallel Computations
White Paper A deterministic dynamic nonlinear time-delay system is developed to model load balancing in a cluster of computer nodes used for parallel computations. The model is shown to be self consistent in that the queue lengths cannot go negative and the... [10 Jul 2008]
Implementation of Load Balancing Algorithms Over a Local Area Network and the Internet
White Paper It emphasize on the effects of delays in the exchange of information among nodes, and the constraints these effects impose on the design of a load balancing strategy. The results show the effect of the network delays and variances in the tasks... [10 Jul 2008]
Load Balancing in Distributed Computing Over Wireless LAN: Effects of Network Delay
White Paper The model takes into account uncertainty in network delays and the variability in the processors' speeds. The statistics of the network delays are estimated experimentally and used in the analytical model to show the effect of the balancing instant... [10 Jul 2008]
MPLS Networking for Non-GEO Satellite Constellations
White Paper However, communication over geostationary satellites suffers from high free space attenuation and long delays. On the contrary Low Earth Orbit (LEO) satellites with their smaller delays have the potential for a worthwhile solution. [10 Jul 2008]
