  • Ravi Prakash
  • Swair Shah

TCP congestion control is the primary enabler for the coexistence of multiple application flows on a single link. It is designed to achieve long-term fairness between the multiplexed flows in a fully distributed manner. However, long-term fairness between TCP flows does not always translate into Quality-of-Experience (QoE) fairness between the ...

With the rapid rise in the number of diverse Internetbased applications, it is to be expected that network traffic patterns will vary widely. Significant traffic fluctuations from what is predicted may require corresponding routing adaptations to avoid congestion. Valiant Load Balancing (VLB), or equivalently two-phase routing, is a scheme that ...

  • Lanzerotti L.
  • Lotko W.
  • Siscoe G.

There are strong economic and "quality of life" reasons for developing a full-service, state-of-the-science National Space Weather Service. At present the nation's space weather services, as their operators acknowledge, fall short of providing forecasts with the reliability, accuracy, and specificity that customers desire. The technological, scientific, and infrastructural resources exist, ...
